12PSD Diesel Injection Pump Test Bench

The 12PSD Diesel Injection Pump Test Bench is a professional testing solution designed for diesel injection pump inspection, adjustment, maintenance and performance testing. With a 12-cylinder testing structure and an 11kW variable-frequency drive system, the machine is designed to meet the requirements of professional diesel repair workshops, fuel injection service centers and engine maintenance facilities.

The test bench combines a Siemens PLC control system, touchscreen operation, Schneider electrical components, automatic electromagnetic oil collection and an independent engine-oil lubrication circuit to provide a practical working platform for diesel injection pump testing.

12-Cylinder Testing Capacity

The 12PSD is designed with a 12-cylinder testing system, allowing testing of multi-cylinder diesel injection pumps and measurement of fuel delivery performance.

The system can measure fuel delivery at different test speeds and evaluate important injection pump parameters. Its multi-cylinder configuration makes it suitable for workshops handling a wide range of mechanical diesel injection pumps.

11kW Variable-Frequency Drive System

The machine uses an 11kW, 380V three-phase main motor with variable-frequency drive.

The test speed can be adjusted according to the requirements of different injection pumps. This allows technicians to perform testing under different operating conditions while maintaining controlled drive speed.

The variable-frequency drive system also provides flexibility when testing different types of diesel injection pumps.

Main Testing Functions

The 12PSD can be used for multiple diesel injection pump testing and adjustment operations, including:

• Measuring fuel delivery from each cylinder at different speeds

• Testing the beginning of fuel delivery

• Testing fuel delivery interval angle

• Checking and adjusting mechanical governors

• Checking and adjusting distributor pumps

• Testing and adjusting boost compensators

• Measuring distributor pump return flow

• Testing 12V/24V distributor pump solenoid valves

• Measuring internal pressure of distributor pumps

• Checking injection pump housing sealing performance

• Testing feed pumps, including VE pump applications

• Providing engine-oil lubrication to the injection pump during testing

These functions make the 12PSD suitable for both routine inspection and professional diesel injection pump repair.

Siemens PLC and Touchscreen Control

The 12PSD uses a Siemens PLC control system for centralized machine control.

A touchscreen human-machine interface allows operators to set relevant testing parameters, operate the equipment and monitor machine status.

This configuration simplifies operation and provides an intuitive interface for daily workshop use.

Independent Engine-Oil Lubrication System

An important feature of the 12PSD is its independent engine-oil lubrication circuit.

During applicable injection pump testing procedures, the lubrication system can provide engine oil to the tested pump. This helps reduce abnormal wear caused by insufficient lubrication and supports stable operation during testing.

Electromagnetic Oil Collection Control

The oil collection tank uses electromagnetic control, eliminating the need for manual operation during the relevant testing process.

This improves operating convenience and increases the level of automation of the test bench.

Pressure and Temperature Monitoring

The 12PSD is equipped with multiple pressure gauges for different testing requirements, including:

• High-pressure gauge: 0–4 MPa

• Low-pressure gauge: 0–0.4 MPa

• Internal pressure gauge: 0–1.6 MPa

• Air pressure gauge: 0–0.16 MPa

• Vacuum gauge: -0.1–0 MPa

The fuel temperature control range is 0–99.9°C, with a temperature control accuracy of ±0.5°C. This helps technicians maintain stable testing conditions.

Standard Configuration

The standard configuration includes:

• 12-cylinder testing system

• 12 test injectors

• Standard pressure calibration nozzles

• S60H nozzle tester

• 40L graduated oil tank

• 12V/24V DC power supply
