Abstract

The invention discloses a test board for flow rate pressure of a pressure regulating valve, which comprises an oil tank, wherein the oil tank is connected with an oil inlet pipeline, and the oil inlet pipeline is connected with an oil pump, a flow rate meter and a pressure sensor and is connected to the pressure regulating valve to be tested, and the pressure regulating valve to be tested is connected with an oil return pipeline; the oil return pipeline is connected with the pressure sensor and is connected to an oil return box; and a data acquiring and controlling device is connected to a flow rate meter and the oil pump to control the oil pump to output a certain quantity of test liquid, wherein the data acquiring and controlling device comprises a processor which is connected to the pressure sensor and used for processing the acquired flow rate pressure data. The test board for the flow rate pressure of the pressure regulating valve achieves the multifunctional test capability to the pressure regulating valve, can simulate the working states of the pressure regulating valve under multiple conditions, and has high automation and intellectualization and high efficiency.

Description

technical field [0001] The invention relates to a testing technology for auto parts, in particular to a testing device for a pressure regulating valve used in an auto. Background technique [0002] At present, the performance test of automotive pressure regulating valve involves the flow pressure relationship test under various working conditions. The current common test method is to use a few sensors to build a simple test pipeline and perform the test manually, which is inefficient. Moreover, the error of manual testing is relatively large, the accuracy of the data cannot be guaranteed, and the data cannot be further analyzed, which seriously affects the testing of automotive pressure regulating valves. [0003] In addition, the existing equipment cannot measure the flow-pressure relationship characteristics of different types of pressure regulating valves by changing different fixtures. The existing equipment cannot display and adjust working parameters in real time; it ...
