1 Vickers Service Guide Vane Pump & Motor Design Guide For Mobile Equipment Revised 8/98 353

2 Introduction Over the past twenty years, the application of hydraulics in agricultural, construction and materials handling vehicles has seen a meteoric rise. In fact, virtually all modern vehicles use fluid power, and new vehicles and markets are appearing as fast as the development of new products and concepts will allow. Vehicle size and work capacity are growing. Today s front-end loaders, for example, have bucket capacities equal to the capacities of scrapers of just a few years ago. To provide equipment with still larger load capacities, and increased speed to do the job faster, the trend is toward high-speed, high-pressure hydraulic pumps and motors that allow system components to remain relatively small. To meet the ever increasing demands for fast positive action, longer service life and economical vehicle operation, Vickers offers you the large selection of top-quality, precision-built pumps and motors described in the following pages. They are backed by over seven decades of experience with every type of hydraulic equipment. You can always depend on Vickers for the finest, most advanced hydraulic products and the best in customer service. Vickers has the worldwide facilities and skilled personnel to give you prompt deliveries, volume production, and application and service assistance when you need it. 2

5 Applying Vane Units Pump Characteristics Maximum Speed Maximum rated pump speeds are based on one atmosphere of inlet pressure (14.7 psia) with the pump at sea level and operating with SAE 1W oil at 38 to 82 C (1 to 18 F), unless otherwise specified. Minimum Speed Minimum recommended starting speed, under fluid conditions stated above, is generally 6 r/min. However, the pump size, system characteristics and environmental conditions can raise or lower this speed. A lower speed can often be achieved after the pump has primed. If low starting or operating speeds are required, consult your Vickers representative. Inlet Pressure Recommended inlet pressure is to,34 bar ( to 5 psi) gauge. Inlet pressure should not exceed 1,38 bar (2 psi). Inlet depressions should not exceed,17 bar (5 of Hg or 12.2 psia). Rated Pressure Pumps should not be operated at or near rated pressures at idle speeds for extended periods. Localized overheating and damage can result. Never assume pumps in a double, triple or thru-drive pump assembly can be simultaneously loaded to rated pressure. Shaft loading must be checked for excessive torque and side loads. Pump Supercharge Pressure A pressurized reservoir system does not always assure a positive(supercharge) pressure at the pump inlet. Vacuum at the pump inlet can result during cold start-ups. Avoid high speeds until the circuit has warmed and supercharge pressure actually exists at the pump inlet. When vacuum breaker pressure caps are used on the reservoir, exercise implements to obtain reservoir precharge. Motor Characteristics Minimum Speed Normal operating motor speeds can be as low as 5 to 1 r/min. Lower operating speeds are permissible depending on torque requirements of the motor and characteristics of the driven load. Stall Torque Motor stall torque ranges between 65% and 1% of 12 r/min running torque for a given pressure differential across the motor. This is dependent on the specific angular position of the shaft at stall and the volume supply of fluid to the motor. Hydraulic Braking Motors may be used as retarders but may not be used as hydraulic brakes. Systems requiring positive holding capabilities must be provided with externally operated mechanical holding devices. The maximum pressure obtainable in a system using a motor as a retarder (pumping) is dependent upon speed. At speeds below 1 r/min, maximum obtainable pressure is proportionally diminished relative to speed as speed approaches stall. When a motor is used as a retarder, adequate pressure must be provided at the inlet port to prevent cavitation. Consult your Vickers representative before using motors as retarders. Drives Recommended Drives Vickers units are designed for use on direct coaxial drives using spline connections and/or flexible couplings. If drives imposing radial or axial loads, or key drives, are being considered, consult your Vickers representative for additional information. Drive Alignment Concentricity and angular alignment of shafts are important to pump life. Misalignment can induce heavy loads on bearings, causing premature failure. Flexible coupling halves must be aligned according to the coupling manufacturer s recommendations. Universal Joints When using double universal joint couplings, the shafts must be parallel and the yokes must be in line. The offset should be kept as low as possible. Maximum allowable offset will, of course, vary with application conditions. The pump shaft to universal joint diametral fit should be close (major diameter fit) with no looseness. Mounting Pad Accessory Drives A splined shaft is recommended on applications where the pump shaft is coupled directly into a transmission or gearbox. Spline drives should be lubricated. The possibility of interference between the shaft and transmission splines, due to tolerance stack-up, can exist. To reduce this possibility, side tooth spline fits should be used. A side tooth fit and short length of engagement permits more flexibility and less tendency for side loading than does a major diameter fit spline or long spline engagement. 5

6 Mounting Dimensions Requirements Dimensional control requirements of the customer s mounting pad to which the pump or motor is affixed are as follows. Pilot Diameter Concentricity of the customer s female pilot diameter relative to the effective axis of the female drive must be within,1 mm (.4 in.) total indicator reading. The clearance between the male and female pilot diameters must be +,1 to +,5 mm (+.5 to +.2 in.). Mounting Face The customer s mounting face to which the pump or motor is affixed must be square to the axis of the female drive within,381 mm per mm (.15 inch per inch). Shafts Dimensions of keyed shaft receivers must be between +,3 and +,3 mm (+.1 and +.1 in.) of the maximum shaft diameter shown on the Vickers installation drawing. Circuitry Requirements Valves In the event of acceleration or deceleration of the drive or driven members, overrunning loads or system bleed-off, control valves and circuitry must provide a continuous supply of oil to the pump or motor. This supply should be sufficient to prevent transient or continuous cavitation, but not so large as to result in speeds beyond the published maximum speed. Protect against hydraulic surge pressures (inlet, outlet or drain) applied to or generated by the pump or motor. Relief valves must prevent these surges from exceeding published pressure ratings. Never assume a relief valve setting is the maximum pressure a pump experiences. Shock conditions may exist which can exceed circuit and pump limitations. Piping Hydraulic lines should be as short and have as large an inside diameter as possible. Where lines are long, it is desirable to adapt to a larger capacity line than a unit s ports specify. Inlet, outlet and drain lines should not be smaller than the nominal port size shown on installation drawings. A Y shaped inlet should not be used to feed two separate pumps because one may be starved and cavitate. There should be as few bends and fittings in lines as possible. High-pressure lines and fittings are restrictive to flow and may result in excessive pressure drop through the system. They should be used only where necessary in a pressure line. Hose Because steering components move during operation, their working hydraulic lines consist mainly of flexible hoses. Long lines may be partly flexible hose and partly tubing where flexibility is not required. When installing a hose, allow enough slack to avoid kinking. A taut hose will not allow movement with pressure surges. Slack in the line compensates for surges, relieving strain. The hose should not be twisted during installation or while in operation. Twisting will weaken the hose and loosen connections. For power steering pumps using a remote reservoir, connecting hoses should not exceed three feet in length. It is highly desirable to design the reservoir-pump relationship so that there is always a static head on the pump inlet port. A neater installation is usually obtainable by using extra fittings to minimize unusually long loops in a line. Hoses should be clamped to prevent rubbing and entanglement with moving parts. Where hoses are subject to chafing, they should be run through protective neoprene hose or shielded metallic guards. Fluid Considerations Preferred Viscosity Normal pump operation (at rated conditions) is based on the use of SAE 1W oil in the 38 to 82 C (1 to 18 F) range (or comparable viscosities). Permissible Viscosity When operating with SAE 1W oil in the 86 to 4 cst (4 to 18 SUS) range (-12 to 35 C or 1 to 95 F oil temp.), the speed and pressure of the pump should be limited to 5% or less of their respective rated value until the system has warmed up. Caution must be used in starting units when fluid viscosity is greater than 86 cst (4 SUS). Care should be exercised to warm up the entire system (fluid). Remote components (cylinders, motors) should be actuated during the warm-up process. Fluid viscosities must not be less than 6 SUS, and temperatures should not exceed 99 C (21 F), because the life expectancy of rotating groups and elastomers will decrease. Care should be taken to change to appropriate oil viscosities when climatic conditions change. See recommendations for mobile hydraulic systems on pages 12 and 121. Consult your Vickers representative for applicable decreases in ratings, and modifications, if fluids other than SAE type oils are considered. Fluid Cleanliness Proper fluid condition is essential for long and satisfactory life of hydraulic components and systems. Hydraulic fluid must have the correct balance of cleanliness, materials, and additives for protection against wear of components, elevated viscosity and inclusion of air. Essential information on the correct methods for treating hydraulic fluid is included in Vickers publication 561; Vickers Guide to Systemic Contamination Control, available from your local Vickers distributor or by contacting Vickers, Incorporated. Recommendations on filtration and the selection of products to control fluid condition are included in this publication. Recommended cleanliness levels using petroleum oil under common conditions are based on the highest fluid pressure levels in the system. See Figure 1. Fluids other than petroleum, severe service cycles or temperature extremes are cause for adjustment of these cleanliness codes. See Vickers publication 561 for exact details. 6

7 Applying Vane Units Aeration Reservoir and circuit design must prevent aeration of the fluid. Particular care must be used to employ joints, seals and gaskets that will not leak or deteriorate. This is especially important in low pressure and suction lines. Connections should always be tight to prevent air from entering the system. It is best to use windows and sight glasses in the reservoir and inlet lines during prototype evaluation to determine whether significant amounts of air are present in the fluid. Any opaqueness or milky appearance of the fluid in the lines or reservoir indicates excessive aeration. Bubbles on the surface of the reservoir fluid may indicate that excessive aeration is present. Reservoirs Oil Level The oil level of the reservoir should be as high as possible above the pump suction line opening. All return lines should discharge near the tank bottom, always below the oil level, and as far from the pump inlet as possible. For power steering pumps using a remote reservoir, the oil level should not be lower than one foot below the pump shaft centerline. Reservoirs should incorporate a sight gauge, dipstick or other means for easy checking of the oil level. Without these devices, the oil level often goes unchecked and, should a leak occur, the pump can be starved and damaged from loss of lubrication. Location Preferably, reservoirs should be located above pumps. This creates a flooded pump inlet which reduces the possibility of pump cavitation. Line Connections Pump suction and tank return lines should be attached to the reservoir by flanges or welded heavy-duty coupling. If the suction line is connected to the bottom of the reservoir, the coupling should extend above the bottom inside the tank. This prevents residual dirt from getting into the suction line when the tank is cleaned. The seals used on all suction line connections should be such that they will not deteriorate and leak. Baffle Plate A baffle plate in the reservoir is desirable to separate the suction and return lines. The plate causes return oil to circulate around the outer wall of the reservoir for cooling before it re-enters the pump. It also helps provide time for entrained air to separate from the oil. Baffle plate openings should be designed so that cascade effects and resultant air entrainment are minimized. Magnets Magnets in a reservoir should be able to pick up ferrous particles not retained by filters or strainers. Magnets should be assembled to the support bars located between suction and return lines, and be accessible for cleaning. Filler/Breather Most reservoirs are vented to the atmosphere through an opening that lets air leave or enter the space above the oil as the oil level rises or falls. A filler/breather unit containing an air filtering element, such as shown on page 118, is often used as the vent. It must be large enough to handle the air flow required to maintain atmospheric pressure whether the tank is full or empty. 7

8 Pump Start-up Procedure Preparation Prior to Start-up The reservoir and circuit should be clean and free of dirt and debris prior to filling with fluid. Circuit Cleanup The reservoir should be charged with filtered hydraulic fluid. The fluid level should be sufficient to prevent vortexing at the suction connection to the pump inlet. It is good practice to clean the system by flushing and filtering, using an external slave pump. Filling Pump and Removing Air If the pump is mounted above the fluid level, it should be filled with fluid through the outlet port. If the pump is mounted below the fluid level, the pump outlet fitting (or other downstream fitting or plug) can be loosened to allow fluid to displace the air. It may be necessary to loosen the fill cap on the reservoir to allow the fluid to flow freely. When a solid stream of fluid with no observed air begins to drain through the loosened fitting, the fitting should be retightened. An air bleed valve in the outlet circuit is also recommended to remove trapped air. If such a device is used, the pump should be filled with fluid before start-up. In some cases, it may be possible to prime the pump by running the engine starter for five to ten seconds with the throttle and/or ignition switch in the off position. It will be necessary to loosen a fitting or plug in the pump outlet to allow air to escape. Pump Start-up All controls should be placed in the neutral position so the pump is unloaded when started. Start the engine and run at low idle. Once the pump is started, it should prime and pump within a few seconds. If it does not, make sure there are no restrictions between the reservoir and the inlet to the pump, and that there are no air leaks in the inlet line and connections. Also, make sure that trapped air can escape from the outlet. Run at low engine idle for approximately five minutes. Then, while observing the reservoir fluid level, operate the implements. Extend all actuators to maximum safe limits to completely fill the system with fluid. Do not run with the fluid level below the low limit. Add fluid to the reservoir to bring the fluid to the proper fill level. 8

9 VQ Series High Speed, High Presure Pumps Design Features Performance Reliability & Efficiency In all pumps, except the rear pump of triple pumps, fluid flow is developed in a cartridge which consists principally of a cam ring, rotor, ten vanes, and unique side plates and support plates. The bimetallic flexible side plates are located on each side of the rotor with their bronze face toward the rotor and their steel face toward the support plate. Two cavities in each support plate hold high pressure oil against the flexible side plate, thereby hydrostatically balancing the flexible plate and providing optimum clearance with the rotor. For a combination of maximum horsepower in a small package, high efficiency, serviceability and economy, Vickers high output pumps are unequalled anywhere in industry. Durability Vickers high speed-high pressure pumps give more staying power they last. Their workhorse ruggedness has been proved on the newest types of giant earth-moving equipment. Axial and radial running clearances, along with lubricating oil film on the rotor and vanes, are optimized over the entire operating pressure range. Excellent cold-start capability and superior resistance to seizure make Vickers VQ pumps highly reliable and efficient. 9

10 Replaceable Cartridge The pump cartridge described under design features is easy to service and can normally be replaced in ten minutes or less, without removing the pump from its mounting. A small stock of cartridges can serve many pump models on a variety of vehicles. Hydraulic Balance Pump inlet and outlet pressure chambers are diametrically opposed as shown in Figure 2. As a result, the rotor is hydraulically balanced. Bearings thus encounter no hydraulic loads, assuring long life. Figure 3 shows an insert fitted into a slot in the vane. Outlet pressure is applied continuously only to the space between the vane and insert. Top and bottom areas of the vane are subject to either inlet or outlet pressure, depending upon the vane s location during rotor rotation. See Figure 2. Complete hydraulic balance is effected in the outlet pressure areas. Outward thrust by the vane in the inlet area is equal to the outlet pressure times the projected area of the end of the insert. Double Pumps Double pumps provide a single power source capable of serving two separate hydraulic circuits, or of providing greater volume through the combined delivery of both sections. In either type of application, two pumps in a single housing result in a more compact, simple installation and can be driven through a single shaft coupling. Triple Pumps Because triple pumps have three pumps in a single housing, they offer even more application versatility than do the double pumps described above. Thru-Drive Pumps These versions of single and double pumps have a rear pad for directly mounting and driving an additional pump. Many different multi-pump arrangements are thus possible. Integral Valve Options Single, double, and triple pumps are available with flow control and priority valve covers. The flow control cover limits flow to the operating system to the desired maximum. Excess flow is diverted to tank. On double and triple pumps, the deliveries of the shaft-end and center pumps are proportional to speed. The flow control cover also includes a relief valve to limit maximum operating pressure. Operating pressures of the shaft-end and center pumps of double and triple pumps must be controlled by separate, external relief valves. A typical application for the flow control is power steering, where it provides a constant supply of oil throughout the vehicle engine s mid to high speed range. The priority valve cover maintains a nearly constant flow to a primary circuit and diverts remaining flow to a secondary circuit. The amount of flow going to the secondary circuit is determined by pump delivery. The primary circuit is protected by an integral relief valve, but an external relief valve must be provided for the secondary and any additional circuit. 1

64 Maximum Torque Loading for Direct Drives Double Thru-drive Pumps As pictured at right, a coupled double VQT pump and thru-driven pump are essentially three pumps driven by one drive shaft. It is critical that the the sum of the torque required for each pumping section not exceed the maximum torque capability of the drive shaft. Use the following procedure to ensure proper loading on the drive shaft: Inlet for pumping sections 1 and 2 No. 2 pumping section (outlet) Inlet for pumping section no. 3 No.1 pumping section (outlet) Drive shaft 1. Determine maximum operating torque of pumping section #1 from Front Pump Torque Requirements figure #1 or #2 at right. 2. Determine maximum operating torque of pumping section #2 from Rear Pump Torque Requirements figure #3 on following page. 3. Determine maximum operating torque of thru-driven pump (pumping section #3) from its specific catalog data, or estimate the torque using the following formula: Torque = (1.15 displacement pressure) 6.28 Note: Actual torque may be higher or lower than estimated.

66 V1, V2, V21 & V22 Single & Double Pumps Versatile High flow, pressure and speed capabilities enable these pumps to meet the needs of modern vehicle hydraulic circuits. Optional flow control and priority valve covers offer even more versatility. Flow Control The flow control cover limits flow to the operating system to the desired maximum. Excess flow is diverted to tank. On double pumps, shaft-end pump delivery is proportional to speed. The flow control cover also includes a relief valve to limit maximum system pressure. A typical application of a flow control is in a power steering unit where it provides a constant supply of oil over the engine s mid to high speed range. Priority Valve The priority valve cover maintains nearly a constant flow to a primary circuit and diverts the remaining flow to a secondary circuit. Flow going to the secondary circuit is determined by pump delivery. The primary circuit is protected by an integral relief valve but an external relief valve must be provided for the secondary circuit. Reliable The superior design of these units makes them last longer... they ve proven they ll hold up in rugged applications such as trenchers, backhoes and tractors. Hydraulic Balance Internal inlet and outlet pressure chambers are diametrically opposed. As a result, pressure-induced radial loads are balanced... bearings have to carry the external load only. Performance Low vane tip/ring loading allows high pressure operation. High speeds are possible because the inlet flow paths are designed to give uniform oil acceleration - thus better filling - particularly at low inlet pressures. Low Cost Vickers efficient design produces extra horsepower per dollar of pump investment - providing industry with low pump cost per horsepower capacity. 66

103 High Speed - High Pressure Motors from 43,9 to 317,1 cm 3 /r (2.68 to in 3 /r) Reliable Vickers has field-proved these high performance motors over many years. They have been overwhelmingly successful on elevator scraper drives, hydrostatic drives and many other auxiliary applications. Efficient Vickers exclusive dual-alternate pressure plate design provides overall efficiency of about 86%. Reversibility Through the dual plate design, the motors may be reversed simply by reversing the direction of oil flow. See note below table on page 14 regarding pressure/rotation of model series 5M. Series Operation Inlet and outlet ports can be pressurized simultaneously without affecting service life or operating smoothness. These motors are suited to series applications. See note below table on page 14 regarding pressure/rotation of model series 5M. Replaceable Cartridge Replaceable cartridges permit motor overhauls in just 1 minutes - in the field! A cartridge can be replaced without removing the unit from the vehicle, and usually without disconnecting hydraulic lines. High Speed and Pressure These motors offer speeds to 3 rpm at maximum pressure. Speeds up to 4 rpm are obtainable, as in transmission applications where high travel speeds under light loads are required. 13

120 Oil Recommendations The oil in a hydraulic system serves as the power transmission medium. It is also the system s lubricant and coolant. Selection of the proper oil is a requirement for satisfactory system performance and life. The following recommendations will assist in the selection of suitable oils for use with Vickers products. Vickers does not publish a recommended oil list by brand name or supplier due to the extremely wide variety of oil types on the market. In most cases, use of these recommendations will lead to selection of a suitable oil. However, due to the complex nature of oil formulation, the variety of oils available and peculiarities of individual hydraulic applications, there will be rare instances where oil selected on the basis of these recommendations will yield unsatisfactory results. Vickers cannot be responsible for such exceptions. In this respect, the customer is encouraged to consult his Vickers representative when selecting an oil. Important Factors In Selecting An Oil Additives Hydraulic fluids contain a number of additive agents which materially improve various characteristics of oil for hydraulic systems. These additives are selected to reduce wear, increase chemical stability, inhibit corrosion and depress the pour point. Pump performance and reliability are directly affected by the antiwear additive formulation contained in the oil. Oils providing a high level of antiwear protection are recommended for optimum performance and long life. Viscosity Viscosity is the measure of fluidity. The oil selected must have proper viscosity to maintain an adequate lubricating film at system operating temperature. In addition to dynamic lubricating properties, oil must have sufficient body to provide an adequate sealing effect between working parts of pumps, valves, cylinders and motors, but not enough to cause pump cavitation or sluggish valve action. Optimum operating viscosity of the oil should be between 16 cst (8 SUS) and 4 cst (18 SUS). Viscosity index reflects the way viscosity changes with temperature; the smaller the viscosity change, the higher the viscosity index. The viscosity index of hydraulic system oil should not be less than 9. Multiple viscosity oils, such as SAE 1W3, incorporate additives to improve viscosity index (polymer thickened). Oils of this type generally exhibit both a temporary and permanent decrease in viscosity due to oil shear encountered in the operating hydraulic system. The actual viscosity can, therefore, be far less in the operating hydraulic system than what is shown in normal oil data. Accordingly, when such oils are selected, it is necessary to use those with high shear stability to ensure that viscosity remains within recommended limits while in service. Chemical Stability Oxidative and thermal stability are essential characteristics of oils for Mobile hydraulic systems. The combination of base stocks and additives should be stable during the expected lifetime of the oil when exposed to the environment of these systems. Suitable Types Of Oil Crankcase Oil Crankcase oil having letter designation SC, SD, SE or SF per SAE J183 FEB8. Note that one oil may meet one or more of these designations. Antiwear Hydraulic Oil These are produced by all major oil suppliers and should consist of good quality base stocks compounded with antiwear, anti-oxidation, and antirust additives. Due to the large number of different antiwear hydraulic oils, it is impossible for Vickers to test its products with all of them and recommend those that are suitable. Because of this, an evaluation procedure was developed for fluid suppliers to establish the suitability of their products for use in Vickers components. Publication M-2952-S, Pump Test Procedure for Evaluation of Antiwear Hydraulic Fluids for Mobile Systems, which gives the details of this test procedure, is available on request. Certain Other Types Of Petroleum Oil Other oils are suitable if they meet the following provisions: 1. Contain the type and content of antiwear additives found in the above designated crankcase oils, and have passed the pump tests as given in M-2952-S. 2. Have sufficient chemical stability for Mobile Hydraulic system service. 3. Meet the viscosity recommendations shown in the following tables.

121 Oil Recommendations and Hydraulic Formulae Arctic Conditions Arctic conditions represent a specialized field where extensive use is made of heating equipment before starting. If necessary, this and judicious use of the following recommendations should be used: 1. SAE 5W or 5W-2 oil. 2. Oils specially developed for use in arctic conditions, such as synthetic hydrocarbons, esters, or mixtures of the two. Skydrol must not be used. Operating temperature should be closely monitored to avoid exceeding a temperature of 54 C (13 F) with any lightweight oil. Special Requirements When special considerations indicate a need to depart from recommended oils or operating conditions, consult your Vickers representative.
