A rotary joint capable of filtering impurities

Abstract

The invention relates to the technical field of rotating connectors, and discloses a rotating connector capable of filtering impurities. The rotating connector comprises a hollow rotating shaft and a shaft sleeve. An end cover is arranged at one end of the shaft sleeve, a union joint is arranged at the other end of the shaft sleeve, bearings are arranged between the hollow rotating shaft and the shaft sleeve, framework sealing rings are arranged between the hollow rotating shaft and the shaft sleeve, an inner filtering net is fixed to the end of the hollow rotating shaft, an outer filtering net is arranged between the outer side of the end of the hollow rotating shaft and the union joint, one end of the outer filtering net is fixedly connected with the hollow rotating shaft through an annular connecting base, the periphery of the inner filtering net is connected with the annular connecting base, a connecting groove is formed in the inner end of the union joint, the other end of the outer filtering net extends into the connecting groove to form rotating connection, a collecting filtering net is arranged on the annular connecting base, and an annular impurity storage cavity is formed inside the collecting filtering net and communicated with an annular impurity channel. The rotating connector has the advantages that impurities in oil liquid can be filtered out, stored and isolated and can be prevented from entering a sealing face, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of rotary joints, in particular to a rotary joint capable of filtering impurities. Background technique [0002] At present, in metallurgy, ship lifting, chemical industry, pharmaceutical and other industries, in rigid pipelines conveying high-pressure fluid, a rotary joint needs to be installed between two relatively rotating pipelines. The rotary joint generally includes a hollow shaft, a shaft sleeve, a connecting The connecting head is connected with the fixed pipe, the hollow shaft is connected with the rotating pipe, and the hollow shaft rotates in the sleeve, so as to realize the connection between the rotating pipe and the fixed pipe. Due to the high-speed rotation of the hollow shaft, high-pressure fluid is conveyed in the hollow shaft. In order to prevent fluid leakage between the hollow shaft and the sleeve, a sealing ring is installed between the outer circumference of the hollow shaft and the sl...

AI Technical Summary

Problems solved by technology

In this type of rigid adapter, when solid particles in the oil enter between the sealing lip and the sealing surface, the wear of the sealing ring will be aggravated, resulting in oil leakage and reducing the service life of the sealing ring
