Mechanical seals are usually made of moving rings, stationary rings, compression elements and sealing elements. Wherein the movable ring rotates together with the pump shaft, and the movable ring and the static ring are tightly bonded to form a sealing surface to avoid leakage of the medium. The action of the liquid in the sealed chamber causes the end face to press on the end face of the stationary ring and the occurrence of the mechanical seal on the end faces of the two rings and the adhesion of the manufacturer to maintain the seal The Compression of the component pressure, the pump can not work in the state, but also adhere to the end of the paste to ensure that the sealing medium does not leak, and to avoid impurities into the sealed end. The sealing element acts as a gap between the sealing ring and the shaft, the action of the static ring and the gap of the gland, and the oscillation of the pump with the elastic element. Mechanical seal in the practice of running with the other components of the pump together to run together, the normal operation of mechanical seals and its own function, external conditions are very linked. But we have to first ensure that their own parts function, auxiliary sealing equipment and equipment technical requirements so that the mechanical seal reflects its role.
Notes of installation
Pay more attention to avoid installation deviation
The compression quantity of the spring should be carried out according to the regulations. Bigger or smaller are not allowed. The error should be within 2 millimeters.
To ensure the beard can move flexibly on the shaft. And the spring should be able to automatically bounce back when the dynamic ring compressing the spring.
Notes of disassembling the mechanical seals
Be careful when disassembling the mechanical seals: don’t work by hammer and chisel in case damaging the mechanical seals. Steel wire hook is available.
Pay all attention to the all mechanical seals when they are used in the two ends of the pump.
Should change the dynamic and static ring parts when the mechanical seal is moved because of the loosening of the lid.
You can find different mechanical seals for pump in Sealcon, such as O Ring Mechanical Seals, PTFE Wedge Mechanical Seals, Flygt Mechanical Seals, O.E.M Mechanical Seals, Elastomer Bellow Mechanical Seals, Metal Bellow Mechanical Seals, PTFE Bellow Mechanical Seals, Single Cartridge Seals, Double Cartridge Seals and Stationary Seats. Meanwhile, we are searching and developing the mechanical seals for the agitator.
In SEALCON, equipped with advanced CNC processing equipment, you can not only buy the mechanical seals, but also buy the mechanical spare parts: sealing rings, spring, O-ring, sleeve and gland. All of our products conform to the standard of DIN24960, EN12756, ISO3069 API610, API682.
