Electronic pump assembly high and low temperature comprehensive performance test bench

Abstract

The invention discloses an electronic pump assembly high and low temperature comprehensive performance test bench. The test bench comprises a to-be-tested pump body, a test oil tank, an oil temperature machine, an oil storage tank, a detection oil path and a detection gas path, the to-be-tested pump body is mounted in the test oil tank, the oil temperature machine and the oil storage tank are respectively connected with the test oil tank, and the detection oil path and the detection gas path are respectively connected with the to-be-detected pump body and are used for detecting the to-be-detected pump body. A constant-temperature interlayer is arranged in the test oil tank of the test bench, low-temperature and high-temperature setting of oil liquid is achieved, and therefore the test efficiency and accuracy are improved.

Description

Technical field [0001] The present invention relates to the technical field of detecting the detection apparatus of the pump, and in particular, to an electronic pump assembly high and low temperature integrated performance test bench. Background technique [0002] At present, the electron pump effect on the market is to increase the oil to a certain pressure, and press the movement surface of the engine and the part of each part of the transmission. The electronic pump structure can be divided into two types of gear and rotor, and the electronic pump after production needs to be installed on various engines or large devices. If the electronic pump will fail, it will lead to abnormal consequences of engine work. Avoiding the above situation, the electronic pump has a test of analog engine industrial control before the factory. As the country has improved the requirements of energy conservation and emission reduction, a simple lubrication and cooling electronic pump on the market ...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many conventional electronic testing and mechanical testing equipment on the market, but there are few electronic pump assembly performance test equipment, especially the equipment that realizes the integration of cold and heat shock at high and low temperature of the assembly is even rarer, and the oil supply in the testing equipment The system has a simple structure and a single function. The control of oil pressure and flow is mainly adjusted by manually adjusting the valve. The adjustment method is not flexible. The oil pump fuel effect is not good, which affects the oil pump test

In addition, in the low-temperature performance test, multiple devices are required to assist, which is inefficient and greatly reduces the validity and authenticity of the test data

[0005] Current problems: 1. Traditional electronic pumps cannot test various products (various electronic pumps, lubricating oil pumps and cooling pumps); 2. Multiple devices are required for low-temperature performance tests; 3. It is impossible to realize one device for high-speed testing Low temperature test; 4. Inefficiency; 5. Unity of control and program; 6. Data collection and curves cannot test various report requirements
