Separation plate for centrifugal fine filter

Abstract

The invention discloses a separation plate for a centrifugal fine filter. An oil passing hole for enabling a front fine filtering chamber and a rear fine filtering chamber of the fine filter to be communicated is formed in the separation plate. A whole separation plate structure is adopted, and when the separation plate is used for the fine filter, all the beneficial effects of an existing fine filter are kept, and good centrifugal filtering capacity is still achieved at a low rotating speed; meanwhile, if the existing structure of one side oil inflow and one side oil outflow is adopted, oil inflow and outflow direct connection is avoided, centrifugal filtering efficiency is improved, and when the separation plate is installed on an engine, the good centrifugal filtering effect is achieved at the low rotating speed; mainly, the oil passing hole formed in the separation plate serves as a channel enabling lubricant to pass, the connecting strength of the separation plate is improved, secondary convergence of the lubricant and impurities is avoided in the separation and purification process, and the better separation effect is achieved; and along with prolonging of the service cycle, the separation effect is not affected seriously.

Description

technical field [0001] The invention relates to an accessory part of an engine and its engine, in particular to a lubricating oil filtering device and its engine. Background technique [0002] The centrifugal fine filter is an important equipment for the engine to purify the lubricating oil and ensure the normal operation of each friction pair. The centrifugal fine filter is generally driven by the rotation of the crankshaft and uses the centrifugal force of the centrifugal guide part to purify the lubricating oil, and the effect is more obvious. The centrifugal fine filter generally includes a shell and a centrifugal guide part located in the shell. After the lubricating oil enters the shell, it flows along the centrifugal guide part through centrifugal force. The solid particles with high density are located at the farthest end of the centrifugal diameter, near the center That is clean lubricating oil. [0003] In the prior art, in order to ensure a good separation and p...

Problems solved by technology

However, this structure is used to pass the lubricating oil through the gap formed between the edge of the separation plate and the housing, and according to the filtering principle of the fine filter, impurities will also accumulate on the edge through the action of centrifugal force, so that the lubricating oil and impurities are separated After blocking and converging, the separation continues in the secondary centrifugation (the inner surface of the separation plate), and the endless accumulation of impurities leads to the gradual deterioration of the separation and purification effect with the prolongation of the service life
