Three screw pump removal and assembly considerations

Three screw pump removal steps:
1, screw pump and motor from the emptying medium (to prevent the motor, toxic media wounding);
2, remove the screw body discharge body;
3, remove the screw pump stator, if necessary, according to the axis of the pump shaft for auxiliary;
4, remove the rotor and the middle shaft;
5, remove the drive shaft and shaft seal;
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.

Three screw pump assembly considerations:
1, the assembly should be carefully cleaned screw parts, inspection, damaged parts should be replaced;
2, the drive shaft twenty thousand when the joint assembly, the seal should be checked for damage, filled with grease in the cavity;
3, the correct installation of bearings so that the shaft rotation flexible, no jamming phenomenon.
4, shaft seal installation: stuffing box installation, the packing gland should be placed in the shell to install the pressure bolt position, easy to adjust the bolt wrench;
5, the body pressed tight, nut tightening should be uniform;
6, mechanical seal installation should be careful, friction deputy face should be clean and coated with grease;
7, when installing the stator, with a lubricant smear rotor, stator cavity surface, is conducive to stator installation;
8, installation and assembly, the coupling installation deviation: △ Y ≤ 0.2mm, △ α ≤ 30 '.
