Submersible pump should be equipped with protection zero or leakage protection device, work within 30 meters around the pump water, no people, livestock into. Submersible pump should be installed in a strong basket and then put into the water, can also be set up in the water around the pump a strong protective fence. The pump shall be upright in the water with a depth not less than 0.5m, and shall not be used in the water containing mud and sand. When the submersible pump is put into the water or put out of the water, the power should be cut off first, and it is forbidden to pull the cable or the outlet pipe.
Pre-start inspection items shall meet the following requirements:
The cable is well insulated.
2. No sundries in impeller and inlet joint
3. Water pipe ligation is firm.
4. Screw plug for air release, water release and oil filling is tightened.
After the power is connected, it should be tested first, and check and confirm that the rotation direction is correct, and the running time outside the water shall not exceed 5 hours. The change of water level should be observed frequently. The distance from the center of impeller to the level should be between 0.5 and 3.0m. The pump body should not sink into sludge or come out of the water. The cable shall not rub against the shaft wall or pool wall.
New pump or new seal ring, after 50 hours of use, should turn open the water seal plug, check the amount of water, oil leakage. When the leakage amount exceeds 5mL, a pressure test of 0.2mpa shall be carried out to find out the cause and eliminate it, and monthly inspection shall be conducted thereafter. When the leakage amount does not exceed 25mL, it can continue to be used. The specified lubricating oil should be changed after inspection.
The repaired oil-immersed submersible pump shall first undergo a 0.2mpa air pressure test to check all parts without leakage, and then add the lubricating oil into the upper and lower shells.
When the temperature is lower than 0℃, after stopping the operation, shenyang submersible pump should be removed from the water and dried up and stored indoors. The insulation resistance of the stator windings of the motor should be measured every three days, and its value should not decline.
