Water pump severe vibration May be uneven rotor, or coupling poor, bearing wear and tear may also be rotating part of the 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. Piping leaks or leaks Nuts may not be tightened during installation. 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. Overheating filler As a result of 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. Pump is not water or not drained The reason for the end of the valve stuck, filtered part of the blockage, high water absorption or water leaks, may also be due to the wrong direction, 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.
