Fuel Injector Test Rig Gas

VPU 500 LGIP offers reliable and accurate testing for MAN Propane injectors

VPU 500 LGIP is a gas fuel injector testing rig designed for effective testing of fuel valves in marine 2-stroke gas engines running on liquid gas. The test unit is a specialized pneumatic/hydraulic test rig designed for testing MAN Propane injectors. This versatile gas fuel injector test rig is equipped with an engine-specific valve holder, making it compatible with various fuel injector valves for precise testing.

Features of the VPU 500 LGIP test rig

• Safety Valves and Sensors: Guarantees safe testing conditions by continuously monitoring system pressure and performance.
• Gas Leakage Monitor: Easily monitors test results and detect gas leakage.

Key benefits of using the VPU 500 LGIP test rig

Increased Operational Flexibility: Ideal for testing various components of gas engine systems, including injectors, valves, and more.

Precision Testing: Ensures accurate results with custom settings for different gas engine models.

Safety Features: Designed with comprehensive safety mechanisms to ensure secure operation during testing.

Comprehensive Gas Injector and Valve Testing with the VPU 500 LGIP test rig

VPU 500 LGIP can perform a range of gas sealing tests and injector tests to evaluate the performance and integrity of your gas engine components. As a result, peak performance and safety can be ensured.

Available Tests: Ensuring Optimal Gas Engine Performance

Non-return valve seal test: Ensures proper sealing performance of non-return valves.

Nozzle leakage test: Detects and measure nozzle leakage for accurate fuel injection.

Function test: Evaluates the full operational performance of fuel injectors and blow-off valves.

Blow-off-, Window-, Resume valve etc.: Tests the functionality and pressure tightness additional valves

To summarize, well-functioning and non-leaking fuel valves are essential for gas engines. Not only for the purpose of efficient combustion, but also to provide safe operation. The VPU 500 LGIP offers reliable and accurate testing for MAN fuel system. As a result, ship owners and technical staff can rest assured that their engine components perform as expected.
Dual fuel systems are particularly important in energy generation, for instance in maritime vessels, power plants and mines. The systems offer greater operational flexibility, cost savings and environmental advantages. In addition, they offer improved energy security, making them valuable across a range of sectors.

MAKE status

The VPU 500 LGIP is specified by MAN as having MAKE status.
