[0004] However, during the actual use of the oil pump, the above factors will change due to different conditions such as speed, oil temperature and oil pressure.
However, the current oil pump test system has a single detection, such as the application number CN201420164999.9, the patent document entitled "Automotive Transmission Oil Pump Performance Detection Device", which makes the detection accuracy of the oil pump not high.

The invention discloses an oil pump test system which comprises a test table. The test table comprises a base, a motor and an oil tank. A test device is arranged in the oil tank, the drive end of the motor is connected with a speed regulation device, and the output end of the motor stretches into the oil tank and is connected with an oil pump assembly to be tested. The test system further comprises an oil inlet pipeline for being connected with an oil absorbing opening of the oil pump assembly to be tested, an oil outlet pipeline for being connected with an oil out of the oil pump assembly to be tested, an adjusting pipeline for adjusting the pressure of the oil pump assembly to be tested and a flow regulation valve, wherein the oil inlet pipeline is provided with a temperature sensor and an oil inlet pressure sensor; the oil outlet pipeline is provided with an oil outlet pressure sensor, an oil outlet pressure adjusting valve and a flow sensor; the adjusting pipeline is provided with a leakage pressure sensor and a leakage pressure adjusting valve; the flow adjusting valve is a one-way hydraulic control valve, the inlet end is communicated with the oil outlet pipeline, the outlet end is provided with a small oil tank , a first control opening of the small tank is communicated with the oil outlet pipeline, a second control opening of the small tank is communicated with the adjusting pipeline, and the flow adjusting valve is communicated when the oil pressure across the first control opening is larger than that of the second control opening. By means of the system, test accuracy is improved.
Description
technical field [0001] The invention relates to the technical field of oil pump testing systems, in particular to an oil pump testing system. Background technique [0002] In order to ensure the safety of the oil pump, it is necessary to test the performance of the oil pump. [0003] Among them, data such as output flow, discharge flow, oil suction pressure, and working torque are all factors used to judge the performance of the oil pump. [0004] However, during the actual use of the oil pump, the above factors will all change due to different conditions such as speed, oil temperature and oil pressure. However, the current oil pump test system has a single detection, such as application number CN201420164999.9, the patent document entitled "Automotive Transmission Oil Pump Performance Testing Device", which makes the detection accuracy of the oil pump not high. [0005] Therefore, how to improve the detection accuracy is an urgent problem to be solved by those skilled in ...
