Analysis of Submersible Pump Not Pumping and its Solution

1. Submersible pump may be a strong vibration motor rotor imbalance, or coupling with poor, bearing wear and tear may also be rotating parts loose, rupture; may be due to the pipe stent is not strong and so on. Can be taken to adjust, repair, reinforcement, replacement and other methods to deal with. 2. Pipe leakage or leakage may be installed when the screw nut is not tight. 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 overheating and packing due to too much pressure packing too tight, cooling water into less than filler, or shaft surface damage. 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. Frequency conversion pump does not absorb or not drain the main reason for the end of the valve stuck, partial blockage of the water, absorbent height is too high or water leakage, may also be due to steering, impeller runner 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.
