The difference between metal bellows mechanical seal and ordinary mechanical seal

The welded metal bellows mechanical seal has good floating and random compensation.

It can compensate for the leakage of the seal ring due to wear, axial turbulence and vibration.

The welded metal bellows itself acts both as an elastic element and as a seal.

There is no auxiliary seal in the middle of the metal bellows mechanical seal, which reduces a leak point;

The frictional resistance of the compensation mechanism improves the follow-up; in the petrochemical industry, the temperature of the welded bellows seal is used.

Not limited by the auxiliary seal; the disadvantages of the PTFE bell seal for corrosive media are

The bellows has a small spring force and an auxiliary spring is required.

The welded metal bellows are made by the interdigitated outer diameter of each wave plate, so that it does not need to consider the direction of the rotation regardless of whether it is used as a stationary or rotary type.

Welded metal bellows can be made of precipitation hardening type stainless steel, high temperature nickel base material and chrome nickel type corrosion resistant material.

Therefore, the welded metal bellows can be used in a wide range of temperatures (-11 ° C - 426 ° C), and in a variety of acid, alkali, salt media. Choose different

The thickness of the wave plate, the number of layers, allows it to withstand pressures of up to 7 MPa in a special pump. Welded metal ripple

The design of the pipe seal is generally balanced, so the pressure on the end face has little effect on the pressure of the end face.

Bellows mechanical seals are not only suitable for non-hydrocarbon media, but also for flashing hydrocarbon media. Close to ordinary machinery

Compared with its service life, the seal has also been greatly improved, so it has a high performance-price ratio.
