Advantages of corrugated hose

Bellows seal itself fully enclosed structure, its structure must occur in the ordinary spring sealing ring and sleeve (or shaft) of the dynamic sealing bellows bomb full advantage of the formation of pressure (seal due to the presence of seals, snap ring having excellent eliminate sets of friction occurs between the relative displacement of the consumption the counterweight part of the ring and sleeve (or axis socketless fitting) position of the ring size of the limitations of dimensional accuracy and heat treatment, its excellent follow-up during use, the balance is often because fluctuations of the apparatus or during the operation, and many other reasons, the phenomenon of the time spent to move the pump, ordinary mechanical seal ring to seal the opening end surface of the presence can not be reset, causing leakage of the mechanical seal and the bellows seal structure to eliminate seal failure means almost independent of the evacuation pump, showing its good compensation, and in light hydrocarbons pump, vacuum the bottom of the column pump excellent, this function is easy to find the bellows seal an important reason is the popularity of applications.sae hydraulic fittings
