Abstract

The invention provides an engine oil pump noise reduction method and device, electronic equipment and a storage medium. The method comprises the steps that a current oil distribution phase of an oil pump is obtained; based on the current oil distribution phase, a phase adjusting strategy of the oil pump is determined, and the phase adjusting strategy is used for reducing an oil suction and discharge port interval angle of the oil pump; and based on the phase adjusting strategy, the current oil distribution phase of the oil pump is adjusted. According to the method and device, the electronic equipment and the storage medium, the oil suction and discharge port interval angle of the oil pump is reduced by adjusting the current oil distribution angle so as to rationalize the oil distribution phase of the oil pump, so that the oil pump can discharge oil in the cavity in time in the high-speed rotation process, the occurrence probability of sudden change of pressure in the cavity is reduced, and the service life of the oil pump is prolonged, and pressure pulsation is reduced, and noise reduction of the oil pump is achieved.

Description

technical field [0001] The invention relates to the technical field of gear oil pumps, in particular to a noise reduction method, device, electronic equipment and storage medium for an engine oil pump. Background technique [0002] The improvement of automobile environmental protection requirements makes the development of engine oil pumps tend to be high-pressure. However, when the oil pump is working, it will emit sharp noise due to excessive oil supply pressure, which will affect the NVH (Noise, Vibration, Harshness) performance of the cockpit. [0003] At present, noise reduction measures for engine oil pumps mainly use sound-absorbing cotton in the engine room to filter the noise of the oil pump, or simply cover the surface of the oil pump with noise reduction technology to reduce noise, but the noise reduction effect is not ideal and cannot meet the requirements Actual noise reduction needs. Contents of the invention [0004] The invention provides an engine oil pu...
