Abstract

The invention discloses an oil filter bypass valve opening pressure gas detection device, which includes a base, a lower mold fixedly installed on the base, a gasket arranged between the lower mold and the base, and a The top inflatable disk, the cylinder connected to the top of the piston rod and the inflatable disk, and the gas path. The invention adopts the air-inflated disk to apply pressure to the spring of the bypass valve. When the external air-intake pressure is greater than the spring force, the bypass valve is opened to realize rapid air intake; the invention uses a cylinder to press the inflatable disk to the lower mold Above, the two are sealed and connected, and the gas will not flow out from the gap between the two when the inflatable disc is inflated. The invention uses air as the test medium for testing, and the device has small volume, simple structure, and is convenient to use, and can be tested at normal temperature, and parts of bypass valves that pass the test can be used, and the device investment cost and detection cost are low.

Description

technical field [0001] The invention relates to a component detection in an engine accessory, more specifically, to the detection of the opening pressure of a bypass valve in a filter core component of an oil filter. Background technique [0002] The function of engine oil is to form a lubricating oil film on the friction surface of each moving part of the engine to lubricate, reduce the frictional resistance between relative moving parts in the engine, and reduce the wear of parts. However, the engine oil itself contains a certain amount of colloid, impurities, water and additives. At the same time, during the working process of the engine, the metal wear debris, the entry of impurities in the air, and the generation of oil oxides make the impurities in the engine oil Gradually increase. If the engine oil directly enters the lubricating oil circuit without being filtered, the sundries contained in the engine oil will be brought to the friction surface of the moving pair, w...
