Air tightness test device for air cylinder cover of diesel engine

Abstract

The invention discloses an air tightness test device for an air cylinder cover of a diesel engine. The air tightness test device comprises a test table, a positioning transmission mechanism, a fixed mechanism and an oscillation temperature-rising mechanism. By the air tightness test device, the working condition of the air cylinder cover of the engine can be simulated by a detection device, the air tightness of the air cylinder cover is detected in real time, the detection data is more accurate and practical, the sealing effect of the air cylinder cover of the engine can be conveniently testedunder different temperatures, different pressures and different oscillation conditions, recording and improvement are further made, and the production efficiency is favorably improved.

Description

【Technical field】 [0001] The invention relates to the technical field of engine accessory processing equipment, in particular to the technical field of a diesel engine cylinder head sealing test device. 【Background technique】 [0002] The cylinder head of the engine is the most complex structure among all parts of the diesel engine, and bears the largest mechanical load and thermal load. It is a box-shaped part with a complex structure. Oil tank mounting hole. It is often in contact with high-temperature and high-pressure gas, so it needs to bear large thermal and mechanical loads. If the engine cylinder head leaks, oil leakage will occur, resulting in deviations in the internal pressure of the engine and making the engine unable to work normally. In order to ensure product quality in the process of processing, an air tightness tester is usually used to test the air tightness of the engine cylinder head, but because the use environment cannot be accurately simulated, it is ...

AI Technical Summary

Problems solved by technology

It is often in contact with high-temperature and high-pressure gas, so it needs to bear a large thermal load and mechanical load. If the engine cylinder head leaks, oil leakage will occur, resulting in a deviation of the internal pressure of the engine and making the engine unable to work normally.

In order to ensure product quality during processing, an air tightness tester is usually used to test the air tightness of the engine cylinder head, but because the use environment cannot be accurately simulated, it is only for the air tightness test in a static state, the test data There is a deviation from the data in the actual use process, which affects the detection effect
