High precision: The welded bellows acts as a spring, and it is a combination of many springs, so it solves the problem of ordinary spring deformation due to centrifugal force, adapts to high rotation, and makes the sealing surface evenly compressed, which helps prevent leakage.
Vibration resistance and flexibility: The bellows is highly flexible and has a very good vibration absorption effect, so it has a strong adaptability to radial runout, axial clearance, vibration and swing, and can effectively prevent leakage.
Simple structure: unlike other ordinary mechanical seals, which are composed of many parts, it has the characteristics of integrated assembly, simple structure and easy assembly
It can adapt to a variety of temperature conditions: the thermal expansion coefficient of the welded bellows is small, and it can be used at low or high temperatures, and there is no O-ring, which can get rid of the temperature restriction, and the design is relatively free.
Suitable for high-pressure working conditions: As the bellows itself can play a balancing role, the corresponding sealing area can be designed to offset the fluid pressure, reduce the friction of the sealing surface, thereby reducing heat generation and wear, and can be used in high-pressure working conditions.
No shaft sleeve effectively protects the pump: The welded bellows mechanical seal does not have an O-ring and does not need to install a shaft sleeve, so there will be no wear of the shaft or sleeve caused by the abrasion of the O-ring, so as to protect the pump. effect
Suitable for corrosive fluids: As long as the welded bellows is made of materials such as Hastelloy 276 with high corrosion resistance, the corrosion problems of springs and O-rings can also be avoided, and the sealing can be effectively realized.
Suspension leakage will not occur: ordinary push-ring mechanical seals, the leaked trace fluid will solidify and deposit when exposed to air, preventing the advancement of the O-shaped moving ring, and weakening or disappearing the bonding force of the seal end surface, resulting in leakage. On the contrary, the welded bellows mechanical seal does not have an O-ring, even if it is solidified, the effect is not large, and it can still rotate steadily, so it has a long service life.
With thread pumping function: The bellows itself has thread pumping function, which can effectively correspond to fluids containing solid particles and help flushing.
