Chun Da screw pump assembly need to pay attention

Spring pump screw assembly matters needing attention 1, the assembly should be carefully cleaned screw parts, inspection, damaged parts should be replaced. 2, the drive shaft twenty thousand joints to the assembly, the seal should be checked for damage, the cavity filled with grease. 3, the correct installation of bearings so that the shaft rotation flexible, no jamming phenomenon. 4, shaft seal installation: packing culvert installation, should use the packing gland tight bolt position in the shell installation window, easy to adjust the bolt wrench. 5, the body pressed tight, tighten the nut 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, smear the rotor with a lubricant, the stator cavity surface, is conducive to the stator installation. 8, installation and assembly, the coupling installation deviation: △ γ ≤ 0.2mm, △ α ≤ 30. Chun Da screw pump disassembly steps 1, screw pump and motor from the emptying medium (to prevent the motor, toxic media wounding) 2, remove the screw pump 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. 6, long-term without the screw pump, to make anti-rust treatment, the method is to use non-painted metal surface smear rust, including the shaft surface, packing housing cavity, and lubrication.
