      With the decrease of winter temperature, pumps in many occasions stop using because of the temperature. At this time, the maintenance and repair of pumps become particularly important. The following is a small edition to share with you the maintenance and repair methods of winter pumps.

      1. When the pump is out of service, it is necessary to drain the remaining water in the pump and pipeline, and clean the external soil, so as not to cause the pump body and pipeline to burst after freezing and freezing.

      2. Iron castings such as bottom valves and elbows of water pumps shall be cleaned with steel wire brushes, then coated with anti-rust paint and then painted, and stored in ventilated and dry places in machine rooms or storage rooms after drying.

      3. Driven by belt, the belt is washed and dried with warm water after it is unloaded and hangs in a dry place without direct sunlight. Also, it should not be stored in a place with oil, corrosive substances and smoke. Under no circumstances should the belt be stained with oil, diesel or gasoline, and not with rosin or other sticky substances.

      4, check ball bearings, such as wear and tear of the inner lining, wear of the ball or surface spots should be replaced. Clean and clean the bearings without changing the available gasoline or kerosene.

      5. Check whether there are cracks or small holes in the impeller of the pump, whether the impeller fixing nut is loose or not, and if there is damage, repair or replace it. If the impeller is worn too much or has been damaged, new impeller should normally be replaced. Local damage can be repaired by welding or by epoxy mortar. The repaired impeller should be tested by static balance test. Check the clearance of impeller wear ring, if it exceeds the specified value, repair or replace it.

      6. Pump shafts with serious bending or wear should be repaired or replaced, otherwise the unbalance of the rotor and wear of related parts will be caused.

      7. The unloaded screw is soaked in diesel oil and washed with wire brush, and coated with oil or butter. It can be reinstalled or wrapped in plastic cloth and put in place (or preserved in diesel oil) to avoid rust or loss.

      Six ways to prevent water pump from freezing

      Icing of pumps is common, especially in northern areas, it is easy to freeze in winter. In view of this situation, we summarize the following measures to maintain the pumps. The following six points for winter pump attention. More maintenance should be made to prevent freeze water pumps and shorten the service life of pumps.

      1, emptying the water in the pump, add water when it is used. Prevent water pump from freezing and cracking.

      2, if the pump freezes, use hot water or boiled water to pour ice into the pump. Or heating the pump housing.

      3. Use downhole pump. The water pump is put underground, and the water pump in the general well is deep from the ground, and it will not freeze.

      4, the use of insulation water...... Add the steam or heat to the insulation layer to freeze the water pump.

      5, the use of non self suction centrifugal pump. When used, add water.

      6, put the pump in a normal temperature environment. Zero degrees.
