Small centrifugal pump leakage fault are mostly due to seal aging, wear and tear, in addition to change the new seal, also can take the following simple method:
A small centrifugal pump seal ring, due to long-term use of losing elasticity, reveal a sealing ring at this time, then find a zero point three to zero point five mm thick piece of paper or cloth cut into slightly bigger than the original seal pad fit into grooves, finally put on the original seal ring.
Second, nylon seal seat in the rubber sealing ring wear, can take out the sealing ring, then switch installation location, such as sealing ring on the fastening lose elasticity or fracture, can remove spring, with an appropriate diameter of wire or iron wire tied tightly.
Three, the first ring is serious wear reveal a nylon ring, and then coated with butter asbestos rope, wrapped around the stainless steel cover on filling to slightly more than the original nylon seat, then fill the butter, then the nylon bolts compaction compaction.
Four, sealing box and cast iron seal ring lose elasticity, can remove seal from cast iron groove, looking for a zero point six to a millimeter thick YingZhiKe cut into the same size, mat in the slot, and then put the seal ring.
Five, the oil hole rubber sealing ring is damaged, can find a piece of fabric, cut into slightly greater than the bolt holes, top add flat mat, set oil hole in the bolt together. Welcome you visit Shanghai excitation resistance pump industry
