Cooling and filtering structure of engine oil pump

Abstract

The invention relates to a cooling and filtering structure of an engine oil pump. The cooling and filtering structure comprises an oil outlet pipe, a cooler assembly, an oil duct, a filter, an oil return pipe and an accessory enamel; the cooler assembly is fixedly mounted on a side plane of the accessory enamel; the filter is mounted on a top plane of the accessory enamel; one end of the oil outlet pipe is upwards and slantwise connected to the cooler assembly, and the cooler assembly is connected with the filter through the oil duct; the oil return pipe is connected to the filter. The cooling and filtering structure of the engine oil pump has the advantages that a quality fault of engine oil pollution produced by possible leakage of the cooler assembly is avoided, the mounting efficiency and the assembly quality are improved, mounting, demounting and maintenance are enabled to become more convenient, the safety and reliability of an engine lubrication system are improved and the service life of the system is prolonged; further, due to an inside and outside temperature difference, water vapor easily gathers on the oil outlet pipe and prone to enter the cooler assembly, and therefore, the oil outlet pipe is arranged in an inclined form, such that the water vapor is led to a portion relatively far away from the cooler assembly along the inclined pipe to be discharged without entering the cooler assembly.

Description

technical field [0001] The invention relates to an oil pump domain, in particular to a cooling and filtering structure for an oil pump. Background technique [0002] The outer end of the existing car engine oil pump is provided with an accessory enamel on a slope, an oil cooler assembly is installed on the accessory enamel on the slope, and an oil filter assembly is superimposed on the oil cooler assembly. Its shortcomings are: because the cooler assembly is prone to water leakage, especially in the colder winter, the oil with higher temperature will easily produce water droplets when it encounters cold air, which increases the hidden danger of water leakage, and the car is easy to enter the engine oil due to water. The engine oil is polluted internally, which affects the lubricating performance and efficiency of the engine; moreover, since the oil filter assembly is superimposed on the oil cooler assembly, it is inconvenient to install, repair and maintain.
