Structure and Function
  1 HW type mixed flow pump include pump body, pump top, impeller and bearing
  2 pump is the part which connect pump with inlet, there is standard clearance between its end surface and impeller, friction will appear if the clearance too small, the efficiency will reduce if the clearance too big, you can achieve the standard clearance by add or decrease paper tray.
  3 seal devices are included by stuffing box, water seal, and ceruse. Purpose:
  1 prevent the air absorbing into pump
  2 prevent the water outflow from pump.
  4 bearing is used to protect the axes rubbing directly with filling.
  5 pump axes' two supporting is the bearing in the bearing body, there is lubricating grease in the bearing.
  6 water-retaining ring can prevent the water flowing into bearing, protected the bearing
