220V Digital Common Rail Injector Test Bench with Flow-meters

The equipment adopts a digital display system, with intuitive and clear test data, which is convenient for operators to observe and judge in real time. With a reasonable overall structure design, it integrates functional modules such as oil temperature control, pressure regulation and speed control, which can meet the testing requirements of different types of common rail injectors. It is widely used in diesel fuel system maintenance stations, professional injector maintenance centers, engine manufacturing and R&D fields, and is an important tool for the detection and calibration of common rail injection systems.

The internal oil lines of the equipment are under high pressure during operation. Never loosen or disconnect any fuel line connections while the equipment is running to prevent serious injury from high-pressure fuel injection. Fuel is flammable — keep the operating area away from open flames and high-temperature heat sources.

2. Electrical Safety

Before using the equipment, make sure the power supply is properly grounded to avoid the risk of electric shock. Keep hands dry during operation. Do not touch the power plug or control panel with wet hands. When the equipment is not in use for an extended period, turn off the main power switch.

3. Keep Hands Clear During Operation

While the equipment is running, never insert hands or tools into the injector mounting station or areas with moving parts to avoid crushing or puncture injuries. In case of any abnormality, stop the machine immediately and cut off the power supply. Wait until the equipment comes to a complete stop before performing any inspection.

4. Personal Protective Equipment

Safety goggles must be worn during operation to protect against fuel splashes. Protective gloves are recommended to avoid skin contact with fuel and oil residue. The operating area should be well-ventilated to prevent inhalation of fuel vapors.

5. Maintenance and Care

Regularly inspect the sealing of oil lines and the condition of the filter. Replace filter elements promptly to maintain fuel cleanliness. Use approved cleaning agents for equipment cleaning; do not rinse electrical components with water. When the equipment is not in use for an extended period, cover it to protect from dust and store it in a dry, well-ventilated location.

Storage and Organization Design
The machine body integrates a drawer-type storage space, which can accommodate tools, accessories and testing consumables. It is convenient for access and storage, facilitating standardized on-site tool management.

Variable-frequency Electric Control System
Equipped with a variable-frequency control module and a neatly wired electrical box, it can flexibly adjust the equipment working conditions. The clearly arranged circuits facilitate later maintenance and troubleshooting.

Hydraulic Oil Monitoring Assembly
It has a built-in independent hydraulic oil tank and is equipped with a temperature observation component, allowing intuitive viewing of the oil temperature status. The specially designed oil drain interface facilitates oil replacement and maintenance operations.

Main Power Safety Switch
An external main load disconnector is installed on the machine body, which can quickly cut off the power of the whole machine. It realizes power-off protection during equipment maintenance and improves operation safety.

Heat Dissipation and Ventilation Structure
Ventilation holes and cooling fans are arranged in multiple positions on the machine body to accelerate internal air circulation during operation, timely dissipate the heat generated by equipment operation, and ensure long-term working stability.

Convenient Movement and Positioning
Equipped with movable casters, it is convenient for the whole machine to be moved and transferred. The casters come with a built-in locking structure, which can firmly fix the machine body during equipment commissioning to prevent displacement during operation.

1. Pre-start Preparation

Check that all oil line connections are secure and all electrical connections are in proper condition to ensure the equipment is in good working order. Verify that the fuel level in the tank is sufficient, and prepare the injectors to be tested according to the test requirements.

2. Injector Installation

Install the injector to be tested into the corresponding test station in the correct orientation, ensuring it is securely mounted and properly sealed to prevent leakage during the test.

3. Power-on and Parameter Setting

Connect the power supply and start the equipment. According to the injector model and test requirements, set the appropriate operating parameters through the control panel, including working pressure and operating speed, to bring the equipment into standby mode for testing.

4. Performing the Test

Start the test program. The equipment will automatically simulate the injector's working condition, with high-pressure fuel driving the injector operation. The operator can read injection quantity, return flow, and pressure data through the digital flow meter and display screen, while observing the spray atomization pattern to evaluate whether the injector performance meets the required standards.

5. Post-test Procedures

After testing is completed, turn off the equipment and release residual pressure in the system. Wait until the equipment has come to a complete stop before carefully removing the injector. Clean the work surface and perform routine maintenance on the equipment.
