The advantages of the bellows stainless steel hydraulic hose fittings

With excellent eliminate the bellows itself fully enclosed structure, ordinary spring seal ring and sleeve (or shaft) bombardment dynamic seal bellows structure is complete the formation of pressure hydraulic valve block(seal collar relative displacement due to the presence of seals card, heat treatment limits the accuracy of the size of the ring and the friction between the the counterweight part of the ring and sleeve (or wave) is very small so that it may be balanced by making use of the process of an ordinary mechanical seals are often given in the device changes, or follow the operation of the method, and many other causes of the phenomenon of pump, to the presence of the open end surface of the removable annular seal member can not be reset, so that the leakage of the seal member and the bellows is fixed to the structure to eliminate by nearly The independent seal failure evacuated by a pump, and shows a good balance, and can be easily found when the light hydrocarbons, the vacuum pump the superior floor pump, this function is an important reason of the popularity of the bellows.hydraulic manifold block
