1, screw pump and motor from the emptying medium (to prevent the motor, toxic media wounding);
  
2, remove the screw pump discharge body (1);
  
3, remove the screw pump stator (6), if necessary, according to the axis of the pump shaft for auxiliary;
  
4, remove the rotor (5) and the intermediate shaft (7);
  
5, remove the drive shaft (44) and shaft seal;
  
6, Remove the screw pump bearing (39) (41), positioning sleeve (40), should be taken out from the bearing housing;
  
7, long-term without the screw pump, to make anti-rust treatment, the method is to use anti-rust grease smear non-painted metal surface, including the shaft surface, the filler housing cavity, and lubrication.
  
Screw pump assembly, precautions:
  
1, the assembly should be carefully cleaned screw parts, inspection, damaged parts should be replaced;
  
2, the correct installation of bearings so that the shaft rotation flexible, no jamming phenomenon.
  
3, shaft seal installation: stuffing box (18) installation, should make the packing gland (16) the position of the bolt in the shell installation window, easy to adjust the bolt wrench;
  
4, mechanical seal installation should be careful, friction deputy face should be clean and coated with grease;
  
5, the drive shaft twenty thousand joints to the assembly, the ring should be checked for damage, filled with grease in the cavity;
  
6, when installing the stator, smearing the rotor with the lubricant, the surface of the stator cavity is conducive to the stator installation;
  
7, the body pressed tight, the nut should be tightened uniform;
  
8, installation and assembly, the coupling installation deviation: △ Y ≤ 0.2mm, △ α ≤ 30 '.
