Abstract

The invention discloses an impact test mechanism of a steering oil pump. The impact test mechanism comprises a fixed base, a pressure regulating mechanism, a pressure measuring mechanism and a loadingmechanism are correspondingly arranged on the fixed base, an oil inlet channel, an oil outlet channel and an oil return channel are correspondingly arranged in the fixed base, wherein an oil inlet ofthe oil inlet channel, an oil outlet of the oil outlet channel and an oil return port of the oil return channel are correspondingly arranged on the fixed base, the oil return channel is arranged between the oil inlet channel and the oil outlet channel, and the oil inlet channel, the oil outlet channel and the oil return channel are all communicated and connected. According to the impact test mechanism of the steering oil pump, the rotation of a rotating main shaft can be better controlled through the arranged loading mechanism, and the experiment success rate can be further improved; and themagnitude of the loaded pressure can be changed through the arranged pressure regulating mechanism, the oil pressure is further increased during a loading experiment, experiment data can be better obtained, and the impact test mechanism is convenient to use.

Description

technical field [0001] The invention relates to the technical field of steering oil pumps, in particular to an impact test mechanism for steering oil pumps. Background technique [0002] When performing a performance test on the steering oil pump, it is necessary to give a certain pressure and frequency of impact tests to the oil pump to assess the reliability index of the oil pump. According to the national standard, it is necessary to do 300,000 impact tests on it. At present, domestic steering oil pump impact tests can be done. There are only a few manufacturers, and the experimental equipment is relatively complicated, and the test cost is also high. Many steering oil pump factories can only do factory performance tests. It is realized by computer controlling the electromagnetic proportional valve, the signal of the pressure sensor is transmitted to the computer, and the computer controls the pressure and pressure holding time to realize closed-loop control. This test me...
