Kettle mechanical seal

Abstract

The invention discloses a kettle mechanical seal applied to the field of mechanical sealing. The kettle mechanical seal comprises a shaft sleeve, a dynamic ring assembly, a bottom flange and a static ring assembly which take the axis of a rotating shaft as a mounting axis, wherein the dynamic ring assembly is connected to the outer surface of the shaft sleeve, the bottom flange is connected to one end of the dynamic ring assembly, the static ring assembly comprises a dynamic ring connecting portion and a flange connecting portion, the flange connecting portion is fixedly connected to the side, far away from the dynamic ring assembly, of the bottom flange, the dynamic ring connecting portion is used for being in sealing connection with the dynamic ring assembly, a through equipment connecting hole position is formed in the flange connecting portion and the bottom flange, and the equipment connecting hole position is used for realizing connection between the mechanical seal and equipment. Direct connection operation between the mechanical seal structure and the equipment is realized through the equipment connecting hole, applications of equipment flanges are reduced, meanwhile, influence on the static ring structure of the mechanical seal cannot be caused when stress is not uniform in the installation process, so that a guarantee is provided for the overall stability of the mechanical seal.

Description

technical field [0001] The invention relates to a mechanical seal for kettles applied in the field of mechanical seals. Background technique [0002] The mechanical seal is a shaft seal device of a rotating machine, and its installation direction is different according to different application environments. For example, when the mechanical seal is applied to a reactor, it is usually installed vertically to the ground plane. The original mechanical seal for the kettle realizes the connection between the mechanical seal and the equipment flange through a long screw. At this time, the static ring seat is in contact with the equipment flange and is subject to a certain installation extrusion force. Usually, the static ring seat is made of silicon carbide material. In this installation process, if the connection force is not well controlled or the force is uneven, the static ring seat will be broken, and the mechanical seal will fail and leak, which is not conducive to the stabil...

AI Technical Summary

Problems solved by technology

Although the wear of the moving ring assembly is small during the working process, the wear debris generated by friction during the working process is also inevitable.

The wear debris can enter the reaction chamber with the pressure, and then produce impurities in the produced product, which is not conducive to the guarantee of product quality and reduces the qualified rate of the product

In addition to the above pointed out that the wear debris generated by the mechanical seal during operation will directly fall into the kettle, or the sealing lubricating fluid will all fall into the kettle after the mechanical seal fails, which will affect the product quality and seriously cause the materials in the kettle to be scrapped. , causing huge losses
