Screw pump several common problems and solutions

Screw pump common several problems and solutions: 1. Screw pump violent vibration: electric rotor may be unbalanced, or bad coupling, bearing wear and tear; may also rotate part of the parts loose, rupture; may be due to pipe brackets Not strong and so on. Can be taken to adjust, repair, reinforcement, replacement and other methods to deal with. 2. Piping leaks or leaks: screw may not be tight when installing. If the leakage is not serious, in the place of leakage or leakage coated with cement or asphalt mixing oil slurry. Temporary repair can be painted wet mud or soft soap. If leakage occurs at the connector, tighten the nut by hand. Leak serious must re-disassembly. 3. Packing overheating: Because the packing is too tight, the cooling water can not enter the packing, or the shaft surface is damaged. Proper relaxation of packing can be taken to clear up the sealing tube blockage and other measures. Filler wear must be replaced by new ones. Soak it in the oil before installation, insert it in turn, and cut it off, which will reduce water leakage. After the last lap packing is installed, the gland should be installed tightly and the tightness should be adjusted during operation. 4. Screw pump is not absorbent or not drained: The reason for the end of the valve stuck more than the partial blockage of the water, absorbent height is too high or water leakage, may also be due to the wrong direction, the impeller flow blockage and so on. After one by one inspection, respectively, to take the end of repair valve, remove the blockage, correct steering, cleaning impeller and other measures to deal with.
