The first is to use the concept of "containers" in transportation to produce container seals. The rotating and stationary parts of this seal are pre-assembled as a whole before installation. After inspection and pressure test, they are fitted on the shaft in the shaft seal box and fixed on the shaft with set screws. Positioning piece, mechanical seal can be put into operation in parallel plane. This not only facilitates but also ensures quality. Welded metal bellows mechanical seals are made into cartridge seals, which has 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 quality. After passing the inspection, just tighten the sealing cover and tighten the screws. Such pre-assembled, inspected and tested sealing components can easily ensure the quality of installation. This cartridge seal has the following characteristics:
(1) No need to measure the working length of the seal during installation;
(2) The axis can be adjusted at any time;
(3) The problem of leakage at startup will not occur because the seals have been tested in advance;
(4) Just install and tighten the sealing cover bolts during installation, the quality is easy to guarantee;
(5) Protect the sealing surface from debris contamination or damage due to operational errors before installation or starting;
(6) The machine equipment can be readjusted after thermal expansion;
(7) The center can be customized by using cooperation;
(8) It is easy to take out the seals for cleaning and inspection without disassembling the machine pump equipment. The API682 standard recommends that all mechanical seals use cartridge mechanical seals.
