Description
Technical field
The present invention is a platform for detecting leakage of pressurizing device, relates to dynamo-electric field.This testing table is developed for supercharger factory or supercharger research unit, is specifically designed to the testing table of supercharger Leak Detection.
Background technology
Between the intermediate of turbosupercharger and the pneumatic plant and between intermediate and the turbine, when static state, allow certain leakage rate.If but the leakage rate when static is excessive, after then supercharger gets into smooth, easily causes faults such as gas leakage, lubricating oil leakage.
At present also there is not the special equipment that is used for the supercharger Leak Detection, so domestic supercharger manufacturer all avoids this detection.Performance when causing homemade supercharger to dispatch from the factory can not get guaranteeing that the homemade supercharger of part just existed and leaks comparatively serious phenomenon after running a period of time.There is this test item in external manufacturer, but relevant devices is not appeared in the newspapers.
Industrial general leak test plant can not be used for the Leak Detection of supercharger at present.Because industrial general leak test plant all is to be used for detecting atomic little leakage rate or leak free situation at present, and turbosupercharger under normal circumstances allows certain leakage rate, and need to know exactly the size of leakage rate when detecting, so general leak test plant ubiquity range is not enough, can't show problems such as leakage flow size.And because the singularity on the supercharger structure, general leak test plant can't be finished the clamping and the sealing of supercharger at all.
So this testing table is developed at this situation just.
Summary of the invention
This testing table is just to detect supercharger when static, under certain gaseous tension, intermediate to turbine end, intermediate to pneumatic plant end, turbine end to intermediate and pneumatic plant end to the leakage rate of intermediate for detecting target.Adopt the digital display flowmeter as testing tool, adopt the clamping and the hermetically-sealed construction of particular design, guaranteed the effective and easy row of supercharger Leak Detection.Designed special supercharger clamping device, made that the location of supercharger and clamping are simple and reliable.
Adopt a plurality of solenoid valves to switch different gas channels, solved the problem that a flowmeter need detect diverse location place leakage flow.
