The attention of screw pump assembly:
1. The assembly should be carefully cleaned, check the parts of the screw pump, the damaged parts should be replaced;
2. Transmission shaft two universal joint assembly, should check whether the sealing ring is damaged, filled with grease in the cavity;
3. The correct installation of the bearings so that the shaft rotation is flexible, no blocking phenomenon.
4. And seal installation: stuffing installation, should make the packing gland bolts position in the shell is installed in the window, easy to adjust wrench bolts;
5. The discharge body pressure fastening timing, screw nut should be uniform;
6. Mechanical seal installation should be careful, the friction pair should be cleaned and coated with grease;
7. When the stator is installed, the rotor and the inner cavity surface of the stator are coated with lubricating oil, which is beneficial to the installation of the stator;
8. Installation, installation of coupling deviation: Delta Y = 0.2mm, delta alpha = 30.
Screw pump removal procedure:
1. Screw pump and motor out of the evacuation of the medium (to prevent motor, toxic medium wounding);
2. Remove the screw pump discharge body;
3. Remove the screw pump stator, if necessary, according to the pump shaft steering wheel for auxiliary shaft;
4. Demolition of the rotor and shaft;
5. Remove the drive shaft and shaft seal;
6. The long-term use of the screw pump, to be used for anti rust treatment, the method for the use of anti rust grease on non painted metal surface, including the shaft surface, the inner cavity of the filler shell, etc..
