Engine part and whole airtightness detection device

Abstract

The invention provides an engine part and whole airtightness detection device, belonging to the technical field of machinery and solving the technical problems of high cost, poor suitability, and the like of the conventional airtightness detection device. The engine part and whole airtightness detection device comprises a stop valve, a multi-head joint, a digital pressure meter and an interface to be tested, wherein the stop valve is connected with a gas source; the stop valve, the digital pressure meter and the interface to be tested are connected with the multi-head joint; gas output by thegas source passes by the stop valve, reaches the multi-head joint and respectively flows to the digital pressure meter and the interface to be tested by the multi-head joint; the stop valve can communicate or break the gas path; and the digital pressure meter can display the pressure value of the gas path. The device has simple structure, low investment cost and great flexibility; and the digitalpressure meter has two alarm colors and is more convenient and intuitive to view.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an engine component and an airtightness detection device for a complete machine. Background technique [0002] The main parts of the engine, such as the cylinder block and cylinder head, etc. should be tested for air tightness of the water jacket and oil passage before installation, and the air tightness test should also be carried out after the assembly of the whole machine is completed. The sealing performance test of the engine can not only detect parts quality problems and assembly quality problems early, but also prevent three leaks to improve the quality and performance of the engine product, that is, prevent air leakage to improve the output power of the engine, prevent water leakage to reduce engine failure, and prevent oil leakage to save energy and protect the environment. ; And for the new engine development process, it can reduce the failure of the engine caused by le...

AI Technical Summary

Problems solved by technology

For this kind of demand, the existing professional air tightness testing equipment such as leak tester can not meet, the professional equipment is expensive, and some of the functions can not be used when testing the air tightness of the engine, resulting in poor performance waste, relatively low cost performance

Other non-professional air tightness detection devices cannot meet the needs of various types of engines, and generally need to purchase several sets of spares, which undoubtedly increases the investment
