Thin oil lubrication system and its anti-oil filter element and oil drain rod

Abstract

The invention provides an oil lubricating system, an anti-oil-overflow filter element of the system and an oil drain rod of the system. The anti-oil-overflow filter element comprises an annular top cover, a cylindrical outer filter net, a barrel-shaped inner filter net and a locking device, wherein the upper end of the outer filter net is fixed to the lower surface of the top cover; the inner filter net is provided with a bottom disc which is located at the lower portion of the inner filter net and closed and vertically and slidably arranged in the outer filter net; when the inner filter net slips into the outer filter net, the upper end of the inner filter net and the inner wall of the outer filter net or the top cover are sealed, and the lower end of the inner filter net and the lower end of the outer filter net are sealed; when the inner filter net slips out of the outer filter net, the upper end of the inner filter net and the inner wall of the lower end of the outer filter net are sealed; and the locking device is provided with a rod piece which can be inserted into the lower end of the outer filter net and pulled out manually and is used for controlling the position of the inner filter net in the outer filter net. According to the oil lubricating system, the anti-oil-overflow filter element of the system and the oil drain rod of the system, the inner filter net can slip out of the outer filter net, the oil flowing area and the oil flowing speed of the filter element are increased, and oil overflow of an oil return pool is prevented.

Description

technical field [0001] The invention relates to the technical field of thin oil lubrication, filtration and oil spill prevention, in particular to a thin oil lubrication system, an oil spill prevention filter element and an oil drain rod. 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. There are a plurality of through holes on the upper support plate 11, and a filter 2 is respectively placed in the through holes, and the thin oil f...
