Slurry floating ring seal
With the rapid development of agriculture and industry , more and more high pressure pumps , pump inlet pressures up to 100 kg / cm ^ 2 , or 200 kg / cm ^ 2 , the liquid temperature up to 200-400C. In this condition there is a certain mechanical seals difficult, and a floating ring seal is more appropriate . Floating ring seal structure is relatively simple ( compared with mechanical seal ) . Run vent most mesons between mechanical seals and packing . Reliable operation, but slightly larger than the axial dimension of other sealing mechanism . Floating ring seal is to use a floating ring face contact and floating units to achieve the axial end face seals , radial shaft seal is a cylindrical surface by floating ring surface of the inner circle of a narrow slit to produce throttling sealed.
Compared with other forms of seals , floating ring seal with self-aligning advantages. Because they can self-aligning, the radial clearance can be done quite so small . Floating ring and the gap between the sleeve and the gap length is an important factor affecting the amount of leakage .
Figure 9-13 in the spring three floating rings play supporting role . Floating ring seal can be designed as a single ring , can also be used in several rings connected with each other , made of a long sealed. Under normal circumstances , should be out of the relief holes floating ring connected to the low pressure region , so as to play a throttling effect of the sealing gap , but not able to block the relief hole . Introduced more than several commonly used seal centrifugal type, slurry pump manufacturer with the scientific and technological development, seal technology itself is evolving , rubber seals, packing , mechanical seals, floating ring seal itself is still in development and improvement, and it is entirely possible the emergence of new seal structure , it is only in the practice of changing reality in order to continue to discover and grasp the inherent law of external things , to promote the development of things .
Centrifugal rotor bearings are bearing components , radial and axial loads. According to the bearing structure can be divided into two categories rolling and sliding bearings .
