Cartridge mechanical seal is one of the many types of mechanical seals, and it also has a wider range of use and characteristics. Therefore, in order to facilitate everyone's choice, let's learn about its relevant characteristics.

The first is to use the concept of 'container' in transportation to produce a container seal. The rotating and stationary parts of this seal are pre-assembled as a whole before installation. After inspection and pressure test are qualified, they are sleeved on the inner shaft of the shaft seal box, fixed on the shaft with set screws, tighten the gland bolts, and remove the container. The positioning piece, the mechanical seal can be in the working state of the parallel plane and put into operation. This not only facilitates assembly but also ensures assembly quality. Welded metal bellows mechanical seals are made of cartridge seals, which have the above advantages. The cassette seal is also a cartridge type mechanical seal. The static ring, moving ring, shaft sleeve, gland and auxiliary seal of this kind of seal are assembled together with a shaft sleeve before installation, which is convenient for checking the assembly quality. After passing the inspection, just tighten the sealing cover and tighten the screws. Such pre-assembled, inspected and tested sealing components are easy to ensure the quality of installation and assembly. This cartridge seal has the following features:

(1) There is no need to measure the working length of the seal during installation;

(2) The axis can be adjusted at any time;

(3) There is no leakage problem at start-up because the seals are pre-tested;

(4) When installing, it is only necessary to tighten the sealing cover bolts, and the assembly quality is easy to ensure;

(5) Protect the sealing surface from contamination by debris or damage due to operational errors before installation or start-up;

(6) The machinery and equipment can be readjusted after thermal expansion;

(7) The center center can be customized by using coordination;

(8) It is easy to take out the seals for cleaning and inspection without disassembling the pump equipment. Cartridge mechanical seals are recommended for all mechanical seals in the API682 standard.
