Axial (Francis) pump flow
2015-06-24 Reads : 113
Axial (Francis) pump flow, commonly used in the extraction of river water or sea water, its spindle bearings generally use synthetic rubber bearings, need to inject water or lubricant to lubrication start, so external demand matching set provides a lubricating water equipment. The use of self-lubricating bearings can improve the starting performance of the pump, improve operational reliability of the pump, reducing bearing wear after replacement frequency and lower operating costs. 1 self-lubricating bearings self-lubricating bearing structure shown in Figure 1 by the jacket, rubber, polytetrafluoroethylene (PTFE) composed of three layers, the structure can be divided into integral, segmented and packaged type three, than the diameter hour with the overall structure. Jacket can be processed into a cylindrical form or flange form. Coat with brass or stainless steel material, corrosion resistant rubber layer is made of nitrile rubber. 2 2.1 performance self-lubricating bearings self-lubricating properties of rubber bearings used in the spindle starting and stopping the low speed range will produce viscous friction phenomenon, high friction, the bearing wear faster, especially if you do not start at the beginning of the injection of lubricant , the dry friction coefficient for fragile bearing, so before starting to be pre-filled into the clean water into the bearings lubricated by the lubricating device externally set. The new self-lubricating bearings with PTFE composites. PTFE has high chemical stability, operating temperature range of -180 ℃ ~ + 250 ℃, resistance to acid, alkali, excellent lubricity and low coefficient of static friction, and has a surface nonstick, so vertical After the axis (oblique) flow pump which does not require pre-injection in the starting lubricating water.
