Hydraulic tube oil filter device

Abstract

The invention discloses a hydraulic pipe oil filter device, which comprises a filter cartridge. The upper and lower ends of the filter cartridge are respectively covered with end covers and bottom covers. The end cover, filter cartridge and bottom cover together form a first filter chamber. A cylindrical filter element is arranged in the first filter chamber, and the end cover, filter element and bottom cover together form the second filter chamber, and a plurality of holes connecting the first filter chamber and the second filter chamber are arranged on the wall of the filter element. The filter hole is provided with a first oil passage and a second oil passage on the end cover, and a first oil passage for communicating with the first oil passage and the first filter chamber is provided in the end cover. The second oil passage and the second oil passage of the second filter chamber. The advantages of the present invention are: simple structure, convenient installation and maintenance, real-time online filtering of large particle impurities in hydraulic pipes, effectively preventing large particle impurities from entering hydraulic equipment or hydraulic stations during the use of hydraulic equipment, and improving hydraulic equipment and hydraulic stations. operation stability.

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...

AI Technical Summary

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
