Transcription

1 Designed for multi-injector endurance testing, the ETB Test Bench can optionally provide shot-to-shot mass measurement. The injectors are precisely subject to variable controls and hydraulic pressures to establish accelerated aging cycles that reproduce the life of a vehicle. Test program cycling can be automated and results are measured and stored for engineering review. EFS distributed bench control delivers dedicated, dynamic control response with stability. But just as important, EFS test bench architecture delivers builtin diagnostics and monitoring connections to increase up-time and peace of mind. ETB Endurance Test Bench

2 Composition ETB - Instrumentation table (1800 mm x 1000 mm) - One EFS 250 cm 3 rail and 3 motor rails - Cooling system with heat exchanger (air / water) - High pressure management system comprising a drive motor and a high pressure pump - Extractable hydraulics drawer for ease of maintenance - Holding tank of 40 liters fitted with a level indicator, drain valve and handle for easy removal - Environmental security tank of 100 liters with level sensor - Cabinet comprising various safety alarms and interlock control - Air extraction vent 2 Composition

3 Benefits Bench for up to 12 injectors, simultaneously Touchscreen Software parameter setting with dedicated diagnostics and front panel status: rail pressure, tank temperature, coil or piezo timing control, test cycles... Flexible, wide range control of coil or piezo injector drive (IPoDs) Flexible, wide range control of the rail pump (HPC) Safety monitoring of the pump and rail (HPC) Equipment test up to 2200 bars (standard), opt. high pressure pump available. 3

4 Descriptive Each injector is fitted with pressure and temperature sensors to monitor the evolution of leak or return flow to determine durability state. Clamping of the injector Various nozzles can be tested by simply fixing adaptations and circuit connections. 4 Descriptive

5 High pressure rail EFS A main rail capacity of 250 cm 3 accumulates the test fluid at high pressure to feed the sub-rail configuration of actual vehicle operation. Max pressure: 3000 bar Length: 350 mm Diameter: 150 mm Connections HP pump inlet Three outputs to vehicule rails Pressure transmitter Safety valve Rupture disc 2500B DESP 97/23 IV Standard reference sensor Two inputs / outputs reserve. High pressure The high pressure pump is controlled by the HPC - a dedicated controller providing fast, tight control and safety monitoring. Software setup provides flexible control for any pump. Pressure: 2000 bar (higher option) Fixed speed: 3000 rpm Direction of rotation: anti-clockwise. 5

6 Descriptive Chassis - Type: Dimensions (mm): 1590 x 1000 x 1800 Low pressure The oil supply to the bench is provided by a low pressure pump motor. 6 The 40 l primary tank supplies the low pressure pump with 3 µm filtered fluid. The pressure can be adjusted via an overflow. The circuit low pressure feeds the high pressure pump. Descriptive

7 Cabinet Integral to the side of the bench, it includes the following elements: Soft starter, HP pump brake and booster pump, Security and safety modules, PLC Power supply module, Relays, fuses... Electrical characteristics Type: 3P + N + E Voltage: 400 V Frequency: 50 /60 Hz Power: 23 kva Hydraulics drawer The hydraulic drawer is located at the front of the bench, and comprises: Primary tank of 40 liters for supplying the oil to the injection pump, Control of feeding pressure, Temperature regulation of the test fluid (oil / water), and A precise filtering of the test fluid. This tank is equipped with security features (level sensors, temperature sensor, safety valve and thermostat). 7

8 Security Safety and interlock devices Starting the test only after locking the cover Control of the drive motors (soft start) Double checks at primary tank: - Temperature of the test fluid (temperature sensor and thermostat) - Fluid level test: two level sensors (critical and security) Check the pressure sensor and mechanical components of the high pressure rail (safety valve and breaking disc) Two emergency stop buttons (punch) Extraction of hydrocarbon vapors. This bench is equipped with an interlocking keyed system to protect against incorrect locking and unlocking. Monitoring primary tray Monitoring the temperature of the test fluid contained in the primary tank is ensured by the automatic bench. Temperature sensor allows for regulation Two level sensors 8 A 70 C pre-set thermostat prohibits exceeding this temperature in this tray (bench stopped). Security

9 Emergency stop The test bench is equipped with two emergency stop buttons: on the bench and on the measurement cabinet. A controller monitors the main functions of the test bench automatically and continuously. In the event of a detected fault on a device, it initiate an emergency stop. Interlock system The cover is made of aluminum profile with a polycarbonate window. Security is managed by the PLC. Opening allowed only if the pressure is below the minimum pressure (P < Pmin) set in the HPC. Opening allowed only if the nozzle outlet temperature (measured by a PT100 sensor) is less than 50 C. 9

10 Software Separate from the bench operating environment control, the ETB Bench supervisory software precisely and reliably configures and queues endurance cycles that are controlled through the fast responding, dedicated distributed controllers and the injector drive controller. The ETB Supervisory software also provides system monitoring of injectors under test. Measurement cabinet Measurement cabinet includes: Industrial PC on which the software is installed (cycle management and data archiving) Rail high pressure controller EFS 8549 (HPC) Injector drive power modules (solenoid or piezo, multi-injector) Diagnostics and buffered, isolated monitoring signals for drive and rail pressure control 24 VDC supply Security elements (light column signal, circuit breaker, disconnector...) 10 An inverter.
