An integrated lubricating oil filter

Abstract

An integrated oil filter comprises a one-way valve, a bypass valve, a spiral spring, a self-seal valve, an oil filter element, an ail filter shell, an oil filter cover, a long screw, a self-locking nut, a shaft elastic retaining ring and an oil filter differential pressure transducer. The oil filter cover is mounted on the lower portion of the shaft elastic retaining ring through the self-locking nut and sleeved with the oil filter shell. The self-seal valve is mounted on the shaft elastic retaining ring through the spiral spring. The one-way valve is mounted on the upper portion of the shaft elastic retaining ring. The bypass valve is mounted on the side of the one-way valve and between an oil outlet and an oil inlet and separated by a partition on the upper portion of the shaft elastic retaining ring. The integrated oil filter has the advantages the oil filter connecting pipes are simplified, self-sealing of internal passages of the oil filer during decomposition oil filtering, oil discharge amount during oil filter decomposition is reduced effectively, oil refilling times are reduced, and system maintenance efficiency is increased.

Description

technical field [0001] The invention relates to the field of lubricating oil filter structure of a lubricating system, in particular to an integrated structure lubricating oil filter. Background technique [0002] The aviation gas turbine engine lubrication system is an important part of the aviation gas turbine engine. It is mainly responsible for the lubrication of the engine's high and low pressure rotor fulcrum bearings, transmission gears and other components. The lubricating oil filter is an accessory to ensure the cleanliness of the lubricating oil system, which can effectively filter the impurities in the lubricating oil. When there are too many impurities filtered in the lubricating oil filter, the filtering capacity of the lubricating oil filter will be reduced. Therefore, the lubricating oil filter needs to be maintained and cleaned frequently. [0003] Usually, the filter element of the lubricating oil filter is designed as a detachable structure, which is conve...

AI Technical Summary

Problems solved by technology

At present, the oil filter of the domestic engine lubricating oil system is usually designed with a one-way valve and a bypass valve, and the removal direction of most filter elements is not completely vertical downward. When disassembling the oil filter element, it is usually necessary to discharge a large amount of lubricating oil in the oil filter and the pipeline. After the oil filter is restored, it needs to replenish the oil, which increases the maintenance time, and at the same time, too much oil leakage from the filter part is easy to pollute the engine compartment
