Thin oil lubrication system and its oil spill prevention filter element with electromagnet

Abstract

The invention provides a diluted oil lubrication system and an oil overflow preventing filter element provided with an electromagnet thereof. The oil overflow preventing filter element comprises a top cover, an outer filter screen with the upper end fixed to the lower surface of the top cover, an inner filter screen provided with a closed chassis located at the lower portion and vertically arranged in the outer filter screen in a sliable mode, a locker provided with a rod-shaped member extending into the lower portion of the inner filter screen and used for controlling the position of the inner filter screen in the outer filter screen and a driving mechanism connected with the rod-shaped member and provided with the electromagnet for controlling the driving mechanism to pull the rod-shaped member, wherein the inner filter screen slides into the outer filter screen, the upper end of the inner filter screen is sealed with the inner wall of the outer filter screen or the top cover, the lower end of the inner filter screen is sealed with the lower end of the outer filter screen, and when the inner filter screen slides out of the outer filter screen, the upper end of the inner filter screen is sealed with the inner wall of the lower end of the outer filter screen. The inner filter screen of the oil overflow preventing filter element provided with the electromagnet can slide out of the outer filter screen, the oil passing area of the filter element is increased, the oil passing speed is improved, and oil overflow of an oil return pool is prevented.

Description

technical field [0001] The invention relates to the technical fields of thin oil lubrication, filtration and oil spill prevention, in particular to a thin oil lubrication system and an oil spill prevention filter element with an electromagnet. Background technique [0002] On the production line of metallurgical enterprises, hydraulic lubrication systems generally exist, such as thin oil lubrication systems, which mostly use net-type oil return filter 2 (referred to as filter 2 for short) to filter thin oil and return oil. Specifically, such as Figure 1-Figure 3 As shown, the high-temperature thin oil with impurities returns to the oil tank 1 through the oil return pipe 14, and the thin oil returned to the oil tank 1 first enters the oil return pool 15 composed of the oil tank wall and the upper support plate 11 placed horizontally. Oil return tank 15 is an open oil return tank. There are a plurality of through holes on the upper support plate 11, and a filter 2 is respect...
