Products Description
As sensing element, shock absorber element, compensation element, sealing element, valve element and pipeline connecting part,metal bellow pipe is widely used in automatic control and measuring instrument, vacuum technology, mechanical industry, electric power industry, transportation and atomic energy industry and other fields.
The characteristics of metal bellows are that they can produce corresponding displacement under the action of pressure, axial force, transverse force or bending moment, and have the characteristics of pressure resistance, vacuum sealing, corrosion resistance, temperature stability and long-term service life.

Main Characteristics

It has superior following ability.As a result of its full closure, in the structure of the elimination of the common spring seal in the ring and axle sleeve (or shaft) of the moving ring seal ring, so that the bellows their elastic rate is fully used to form a specific pressure.
High temperature resistance.As the bellows seal is not affected by the common spring seal in the moving ring seal, the applicable medium and temperature greatly expanded.
Balance.Bellows seal and ordinary seal, do not need to process steps on the shaft sleeve, itself can be established to balance the diameter, in a balanced state (generally for partial balance).
Little leakage.The sealing point of moving ring and static ring is sealed and connected with metal or non-metal gasket by means of bolt fastening, so it is very difficult to leak. In fact, the leakage point of bellows seal is only the friction pair, which is the dynamic sealing point, so there is no doubt that the leakage probability is greatly reduced.
Vibration resistance and high speed.The bellow seal eliminates the moving ring seal ring, greatly reduces the vibration caused by the pump body vibration or axial vibration through the moving ring seal ring transmission caused by the moving ring vibration, so that the moving ring from the big impact, which is usually called the floating seal.
The specific pressure of spring can be reduced.In the use of ordinary mechanical seal process, the specific pressure of spring is generally designed in 0.15 ~ 0.25mpa, and the specific pressure of the bellows seal spring is generally designed between 0.05 ~0.15mpa. When the bellows seal is static structure, the spring is significantly smaller than the pressure.
Itself can transmit torque.Bellows seal can transmit torque directly, which can be simplified in structure, avoid the failure caused by transmission structure, and improve the reliability of mechanical seal.
