Problems solved by technology

Since it takes a long time when the oil is heated or cooled, the oil pump performance test takes a long time and the test efficiency is low
For manufacturers of mass-produced oil pumps, the slow detection speed cannot meet the needs of mass production and affect the economic benefits of the enterprise

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 and figure 2 As shown, the oil pump performance testing device of the present invention includes a workbench 1 and an oil tank 2. The workbench 1 is connected with an oil pump 3 to be tested, and it also includes a control module 12 and a data display module 13. The oil tank 2 communicates with the oil suction port of the oil pump 3 to be detected, the oil outlet of the oil pump 3 to be detected is connected with an oil discharge pipe 6, and the outlet end of the oil discharge pipe 6 is connected with a main oil pipe 9 and an oil return pipe 10, and the main oil pipe 9 is connected with an oil return pipe 10. The outlets of the oil pipe 9 and the oil return pipe 10 are all in communication with the oil tank 2; the oil discharge pipe 6 is sequentially connected with a flow sensor 4, a first pressure sensor 5 a...

Abstract

The invention discloses a performance testing device for an oil pump. The device comprises a workbench, an oil tank, a control module and a data display module, wherein the oil tank is communicated with an oil suction port of an oil pump to be detected; an oil outlet of the oil pump to be detected is communicated with an oil discharging pipe; the outlet end of the oil discharging pipe is communicated with a main oil pipe and a return oil pipe; outlets of the main oil pipe and the return oil pipe are communicated with the oil tank; a flow sensor, a first pressure sensor and a first pressure regulation valve are sequentially connected to the oil discharging pipe along an oil discharging direction; a second pressure sensor is connected to the main oil pipe; a second pressure regulation valve is connected to the return oil pipe. According to the performance testing device for the oil pump, a changing relationship between the pressure and the flow of an outlet of the oil pump at different temperature is simulated and tested at the same temperature, and the device is short in testing time and high in testing efficiency.

Description

technical field [0001] The invention relates to the technical field of engine oil pump performance detection, in particular to an engine oil pump performance test device. Background technique [0002] The role of the oil pump is to provide reliable lubrication to key parts such as the engine and gearbox of the car. The oil pump is generally composed of a housing, an inner rotor, an outer rotor and a pump cover. Before the oil pump leaves the factory, a bench test for performance testing is generally carried out to ensure the qualified products of the factory. Generally, when performing the performance test of the oil pump, it is necessary to test the curve of the relationship between the outlet pressure and flow of the oil pump at different specified oil temperatures, so as to compare it with the curve of the relationship between the outlet pressure and flow of the oil pump at different specified oil temperatures Yes, so as to determine whether the performance of the oil p...
