Abstract

The invention relates to the technical field of product detection, and particularly discloses an oil pump quality detection system which comprises a pressure testing device and a height difference detection device, the pressure testing device comprises a testing table and a pressing mechanism, and the pressure testing device is located in the front process of the height difference detection device. The pressing mechanism comprises a pressing plate, a pressing disc connected to the pressing plate and a plurality of pressing rods, an upper sealing gasket is arranged at the bottom of the pressing disc, a lower sealing gasket is arranged on the testing table, and the upper sealing gasket and the lower sealing gasket can seal the upper end face and the lower end face of the oil pumping cavity of the pump body. According to the scheme, the pressure testing device is arranged between the height difference detecting devices, so that the opening pressure of the pressure regulating valve can be conveniently tested before the oil pumping structure is mounted on the pump body, and the problem that the performance of the oil pumping structure in the oil pumping cavity of the pump body is influenced by high pressure of high-pressure gas in the opening pressure testing process of the pressure regulating valve in the prior art is solved; in addition, through the height difference detection device, the height difference between the inner and outer rotors and the end face of the pump oil cavity of the pump body is rapidly and accurately detected.

Description

technical field [0001] The invention relates to the technical field of product detection, in particular to an oil pump quality detection system. Background technique [0002] Diesel (or gasoline) engines are generally equipped with an oil pump. The oil pump includes a pump body, an oil pump structure installed in the pump oil cavity of the pump body, and a pump cover that seals the pump oil cavity. The pump that sucks the oil into the oil pump through the oil pump In the oil chamber, the inhaled engine oil is discharged under pressure into the engine oil filter and each lubricating oil passage, so as to realize the functions of lubrication, friction reduction, cooling, corrosion protection, shock absorption and other functions for each transmission pair of the engine. [0003] The oil pumps equipped with large-flow diesel (or gasoline) engines need to be equipped with safety protection components, pressure regulating valves (also known as safety valves or pressure limiting v...
