Problems solved by technology

Due to the special danger of the operation and use of the marine diesel fuel injector test bench itself and the complexity of using two display systems in parallel, there have been personal injury accidents in which leaked high-pressure oil penetrated clothing and skin.
The main reason for this is that the components of the new technology product structure do not match and the design pressure is insufficient in the stage of discussion and use. Another important reason is that personal injury accidents and mechanical failure accidents occur due to irregular use and operation.

Abstract

The invention relates to a test stand for a marine diesel injector and a testing method for the injector, characterized in that the test stand for the marine diesel injector integrates a mechanical manometer display system and an electronic liquid crystal tester display system, mainly composed of a pneumatic hydraulic pump system, a system connecting the injector and fuel equipments and an electronic sensor system, capable of performing leakage test and calibration test on the injector, testing the release pressure of the slide valve in the nozzle component of the injector and the sealing property of a valve line, testing the open pressure of the injector, checking the atomization quality, and testing the seal of the sealing ring of the nozzle. Because of the two set of tester display systems of the testing stand, a tested injector has high precise and accurate testing quality; when the testing method is performed standardly, unsafe factors can be reduced and avoided.

Description

technical field [0001] The invention relates to the detection field of a fuel injector for a marine diesel engine, and relates to a test bench for a fuel injector of a marine diesel engine and a test method for a fuel injector Background technique [0002] In the repair and maintenance of diesel fuel system, especially in marine diesel fuel system, injector tester is one of the indispensable test instruments. The operating status of the fuel injector of a marine diesel engine has a great influence on the overall use effect of the diesel engine and the endurance of the ship. The detection of fuel injectors is one of the routine inspection and maintenance of ships. At present, manual and pneumatic test benches are generally used to detect fuel injectors at home and abroad. Manual type: The operator has high technical requirements, the number of manual operations should not be too small, and the force should not be too small. The atomization test requires at least two speeds...
