Set installed seal - cartridge seal |
The first is set using the transport seal installed in the "container" concept, resulting in a cartridge seal. This seal rotating and stationary parts of preloaded before installation into a whole, after inspection and pressure test kit in the seal chamber after passing the shaft with set screws fixed to the shaft, the gland bolts, remove the container positioning pieces, mechanical seals can work in parallel to the surface state, put into operation. This not only easy to assemble and assembly quality assurance. Currently welded metal bellows mechanical seal are made cartridge seal, it has the above advantages. Cassette seal is also a cartridge mechanical seal. This seal stationary ring, ring, sleeve and gland and secondary seal before installation are set by a sleeve mounted together, easy to check the quality of assembly. After passing the examination as long as the tight cover, tighten the screw. Such prior assembly, inspection and testing of the seal assembly, easy installation and assembly quality assurance.
This cartridge seal has the following characteristics:
(A) without measuring the working length of the seal installation;
(2) axis can be adjusted at any time;
Leakage problem (3) does not happen to start, because seals are pre-tested;
(4) Set the installation just close the cover bolts, easy assembly quality assurance;
(5) protect the sealing surface before installing or starting from debris contamination or damage due to operator error;
(6) Machinery and equipment of thermal expansion can be re-adjusted;
(7) can use with self-centering;
(8) the sealing member be easily removed for cleaning and inspection without disassembling the pump device. API682 standards recommend the use of all mechanical seal cartridge mechanical seal.
