Hydraulic tube oil filter device

Abstract

The invention discloses a hydraulic tube oil filter device, which comprises a filter drum, wherein an end cover and a bottom cover are separately arranged on the upper end and the lower end of the filter drum; the end cover, the filter drum and the bottom cover form a first filter chamber together; a cannular filter element is arranged in the first filter chamber; the end cover, the filter element and the bottom cover form a second filter chamber together; a plurality of filter holes communicating the first filter chamber with the second filter chamber are formed in the cannular wall of the filter element; a first oil hole and a second oil hole are formed in the end cover; a first oil passage used for communicating the first oil hole with the first filter chamber is arranged in the end cover; and a second oil passage used for communicating the second oil hole with the second filter chamber is arranged in the end cover. The hydraulic tube oil filter device has the advantages that the structure is simple; the installation and maintenance are convenient; large particle impurities in a hydraulic tube can be filter out online in real time, and are effectively prevented from entering hydraulic equipment or a hydraulic station in the use process of the hydraulic equipment; and the operation stability of the hydraulic equipment and the hydraulic station is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure, in particular to a hydraulic pipe oil filter device for on-line filtering oil in a hydraulic pipe. Background technique [0002] At present, hydraulic equipment for steelmaking and continuous casting is generally controlled centrally through a hydraulic station, which is connected to the hydraulic equipment through hydraulic pipes. As the hydraulic equipment moves, the oil moves back and forth in the hydraulic pipes. During the use of hydraulic equipment, the oil in the hydraulic pipe will be mixed with large particles of impurities such as broken seals and iron oxide, and the number of large particles of impurities will continue to increase with the prolongation of the use of hydraulic equipment. When the large particles of impurities When the oil enters the hydraulic equipment, it is easy to jam the seals of the hydraulic equipment, resulting in internal leakage of the hydraulic equi...

Problems solved by technology

During the use of hydraulic equipment, the oil in the hydraulic pipe will be mixed with large particles of impurities such as broken seals and iron oxide, and the number of large particles of impurities will continue to increase with the prolongation of the use of hydraulic equipment. When the large particles of impurities When the oil enters the hydraulic equipment, it is easy to jam the seals of the hydraulic equipment, resulting in internal leakage of the hydraulic equipment; when large particles of impurities enter the hydraulic station with the oil, it is easy to jam the hydraulic valve in the hydraulic station, thereby affecting the hydraulic pressure. device action
