High-temperature-resistant mechanical seal unit

Abstract

The invention discloses a high-temperature-resistant mechanical seal unit which structurally comprises a fastening and sealing bearing, a bearing nesting cover, a mechanical sealing column casing, a rubber sealing ring, an outer welding ring, an inner column casing pipe, an inner welding ring, a bearing nesting base, a fixing bolt hole and a mechanical sealing base. The mechanical sealing column casing is vertically nested in the bearing nesting cover; the rubber sealing ring and the axis of the mechanical sealing column casing are collinear; the rubber sealing ring is horizontally embedded inthe mechanical sealing column casing; the inner column casing pipe is arranged between the outer welding ring and the inner welding ring; the inner column casing pipe and the mechanical sealing column casing are welded into an integrated structure through the outer welding ring and the inner welding ring. The fastening and sealing bearing is provided with a fastening and sealing column casing, afastening and sealing opening, a clockwise-rotating sealing bearing and an anticlockwise-rotating sealing bearing, high-temperature-resistant flexible mechanical sealing bearing reinforcement is achieved, the sealing performance is more stable, disassembling and assembling are convenient, the matching degree is high, sealing is efficient, and falling is not likely to happen.

Description

technical field [0001] The invention relates to a high temperature resistant mechanical seal, which belongs to the technical field of mechanical seal equipment. Background technique [0002] Mechanical seals are one of the basic components of machinery with precision and complex structures. They are key components of various pumps, reaction synthesis kettles, turbocompressors, submersible motors and other equipment. Their sealing performance and service life depend on many factors. Such as selection, machine accuracy, correct installation and use, etc. [0003] The prior art discloses a high-temperature-resistant mechanical seal with the application number of CN90221154.4, which is a mechanical seal device with special structure and materials. Assembly, and can effectively transmit the torque required for sealing work. The wedge-shaped auxiliary gasket made of special materials enables the seal to withstand high temperatures. This utility model is a balanced mechanical seal...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a high temperature resistant mechanical seal to solve the problem that the flexibility of the high temperature resistant mechanical seal is not high, the spring pressurized nested seal is often used, and the sealing parts cannot be fastened, and the spring If it is loose, it is easy to fall off, and the problem of incomplete sealing
