Mechanical seal assembly structure capable of avoiding oil seal leakage

Abstract

The invention provides a mechanical seal assembly structure capable of avoiding oil seal leakage, and relates to the technical field of bearing connection. The mechanical seal assembly structure aims to solve the problems that when an existing mechanical seal assembly structure is used, due to the fact that a pump, a compressor or a reaction stirring kettle and the like generate vibration in the operation process, the stability of the bearing connecting position of a mechanical seal assembly is low, the sealing effect is affected, and meanwhile, resonance is generated in the mechanical seal assembly, so that abrasion between a static ring and a limiting ring is serious, and the service life of the device is shortened. The mechanical seal assembly comprises a movable ring, the static ring is arranged on the right side of the movable ring, and an inner cylinder penetrates through the movable ring and the static ring. Due to the fact that a connecting ring is arranged between two oil seal rings, the two ends of a supporting spring are connected with the two oil seal rings in a supporting mode correspondingly, the inner diameter length of the connecting ring is matched with the inner diameter length of the oil seal rings, the connecting ring is connected with a clamping groove in a clamped mode through a clamping plate, the two oil seal rings can be prevented from shaking left and right, and the sealing effect of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of bearing connection, and more specifically relates to a mechanical seal component structure for avoiding oil seal leakage. Background technique [0002] Mechanical seal is a general shaft sealing device, which is commonly used in rotary fluid machinery such as pumps, compressors, and reaction stirring tanks, and is also used for sealing gear boxes, valves, rotary joints, and ship stern shafts. A device that solves the sealing between the rotating shaft and the machine body. [0003] For example, the application number: CN201921528667.3 relates to a leak-proof mechanical seal assembly, including a shaft sleeve and a positioning plate. There is a spacer inside, the left end of the static ring is connected with the bearing box through the supporting spring spring seat and the transmission seat, and the bearing cover is installed on the left end of the bearing box, and the positioning plate is fixed on the tr...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a mechanical seal assembly structure that avoids oil seal leakage, so as to solve the problem that the existing mechanical seal assembly structure is in use due to the vibration generated during the operation of the pump, compressor or reaction stirring tank, etc. The stability of the bearing connection of the mechanical seal assembly is low, which affects its sealing effect. At the same time, resonance occurs inside the mechanical seal assembly, resulting in serious wear between the stationary ring and the limit ring, which reduces the service life of the device.
