Vane type oil pump and application thereof in engine lubrication system

Abstract

The invention is applicable to the technical field of automobile engine pre-lubrication, and provides a vane type oil pump. The vane type oil pump comprises: an oil pump mechanism used for introducingengine oil through rotation of vanes and pumping the engine oil by pressurization; a pneumatic mechanism being in connection and transmission with one side of the oil pump mechanism and used for driving and putting the oil pump mechanism into synchronous operation through a pneumatic mode; a driving mechanism being in transmission and connection with the oil pump mechanism and used for driving the oil pump mechanism to operate; and a pre-acting mechanism connected with and arranged on the pneumatic mechanism and used for generating gases before operation of the driving mechanism and timely transmitting the generated gas to the pneumatic mechanism. According to the invention, the pneumatic mechanism drives and puts the oil pump mechanism into operation, the oil is pumped out for lubrication before starting of the engine to reduce the wearing between each friction pair and effectively improve the service life of the engine and parts thereof, the repeated driving at any time can be achieved, the engine can be completely pre-lubricated only by installing one oil pump, and cost and space are saved.

Description

technical field [0001] The invention belongs to the technical field of pre-lubrication of automobile engines, and in particular relates to a vane type oil pump and its application in an engine lubrication system. Background technique [0002] According to statistics, at present, about 30% of the world's energy is consumed in various forms of friction, and the same is true for engines. The internal wear loss power of engines in different technical states accounts for 20% to 25% of the indicated power, and the wear is serious. The engine can even reach about 35%. The wear and tear of the vehicle engine is mainly manifested at the moment of starting, especially when it is cold or hot. The joint test of the American Society of Automotive Engineers and Douglas shows that the wear of the engine during cold start accounts for between 60% and 80% of the total wear. Therefore, in order to avoid the boundary friction and dry friction state that may be caused by the friction pairs of...
