How to repair and maintain the water pump?
1. In addition to strictly following the installation and operation instructions, the use of the pump should also pay attention to two points:
First, it is important not to rely on experience alone. For example, when the bottom valve leaks from the water pump, some operators try to save trouble, before each start-up, fill some dry soil to the inlet nozzle, and then fill the soil with water to flush the bottom valve to make the bottom valve not leak. This method may seem simple and easy, but it is not advisable.
Because when the pump starts to work, the sand in the bottom valve will enter the pump with the water, wear the impeller, pump casing and shaft, etc., seriously affect the service life, the correct way should be to overhaul the bottom valve, which can not be repaired and replaced.
Second, if the fault is found, it should be eliminated in time, and the unit should not be allowed to work with illness. For example, when it is found that the packing of the pump shaft is seriously worn, the packing should be increased in time, otherwise the packing of the pump shaft will leak. The leakage of the shaft packing of the water pump not only makes the energy consumption of the unit too large, but also causes cavitation, which accelerates the damage of the impeller and directly affects the service life of the water pump.
For another example, if the pump is found to vibrate violently, it should be stopped immediately for inspection, otherwise if the pump is bent and deformed, a safety accident may occur. Web Links.
2. After a period of use, the pump unit and pipeline should do the following maintenance work.

Add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil standard, and the lubricating oil should be replaced or replenished in time.
Unscrew the water diversion plug of the BQS submersible pump body, and fill the water diversion (or slurry).
Close the gate valve of the outlet pipeline, the outlet pressure gauge and the inlet vacuum gauge.
Jog the motor and try to see if the motor is steering correctly.
Start the motor, when the BQS submersible pump is running normally, open the outlet pressure gauge and the inlet vacuum pump, and gradually open the gate valve after it shows the appropriate pressure, and check the motor load at the same time.
Try to control the flow and head of the BQS submersible pump within the range indicated on the sign, so as to ensure that the BQS submersible pump operates at a relatively high efficiency point, so as to obtain a relatively large energy-saving effect.
During the operation of the submersible pump, the bearing temperature should not exceed the ambient temperature of 35C, and the relatively high temperature should not exceed 80C.
If you find that the zhongmeibqs submersible pump has abnormal sound, you should stop it immediately and check the cause Ali 02.
When the submersible pump is to be stopped, close the gate valve and pressure gauge first, and then stop the motor.
The lubricating oil of the submersible pump shall be changed after 100 hours within the first month of operation, and the oil shall be changed once every 500 hours thereafter.
Adjust the packing gland frequently to ensure that the drip leakage in the packing chamber is normal (it is advisable to leak out the drip).
Regularly check the wear of the shaft sleeve, and replace it in time after the wear is large.
When the BQS submersible pump is used in the cold winter season, after stopping, the lower part of the pump body should be unscrewed to release the medium to prevent freezing and cracking.

1. Maintenance of submersible electric pump.
1.Electrical:
1) Always check the operating voltage and current of the submersible pump. The three-phase voltage measured by the voltmeter should be basically the same, and at 340 420V, the three-phase current measured by the clamp ammeter should be basically the same, and the rated current should be times the same.
2) Regularly check the thermal insulation resistance of the submersible electric pump to the ground. After 4 6 hours of normal continuous operation, the insulation resistance of the motor winding to the ground should be measured with a megohmmeter when the machine is stopped. For submersible electric pumps that have been out of service for a long time, such an inspection should also be done before use.
3) Before turning on the machine, check whether the sensitivity of the thermal relay and other protection devices are working normally.
4) Check whether the cable is damaged. For oil-immersed submersible pumps, it is necessary to pay attention to the damaging effect of oil seepage of the electric pump on the cable insulation rubber.
2.Mechanical:
1) Always check the mechanical seal of the submersible electric pump. Open the oil hole screw and release a small amount of oil, if the oil contains water, it means that the seal of the upper grinding block (or lower grinding block) has leaked, and the sealing box should be replaced and new cooling oil should be added. If there is a lack of oil in the oil hole or the oil quality is not good, the oil should be filled up (No. 5 or No. 10 mechanical oil, sewing oil or transformer oil) or replaced with new oil.
2) For the new or replacement of the submersible pump with grinding block, after using 50h, the water sealing plug should be unscrewed, check the amount of oil (water) leakage, <5ml indicates that the seal is normal, and can continue to be used, such as 5ml, then the oil (water) is drained and the sealing plug is tightened, and the second inspection is carried out after continuing to use for 50h, if it is still 5m1, it means that there is a problem with the seal. For used submersible pumps, check the leakage once a month, which should be 25ml, and can be used again after drying.
3) Check the vibration of the pump motor, and the synchronous speed is n0=3000r min, 1500r min, 1000r min, 750r min, and the vibration value is required to correspond to δ respectively.
4) Regularly check the bearing condition of the submersible electric pump. See whether the bearing is short of oil, whether there is a situation of running the inner ring or running the outer ring, and whether the bearing needs to be replaced (it is best to replace the bearing of the water-filled electric pump once a year). 3.Miscellaneous.
1) Always check whether the water inlet net cover of the submersible electric pump is blocked by weeds and dirt, and whether the impeller is entangled.
2) The submersible electric pump that has not been used for a long time should be lifted out of the water, cleaned and dried, and stored upright in a dry and ventilated room.
3) After the submersible electric pump runs for 1 or 2 years, the motor should be checked and cleaned with core pulling. If there is dirt, the motor can be immersed in the Haiou TX-10 or 105 detergent solution, heated to about 100 and stirred to speed up the dissolution of the dirt, 1 2h after the dirt is eliminated, and then rinsed with high-pressure tap water to clean the water droplets, put it in the furnace and dry it at low temperature. You can go to Xi'an South Pump Factory to have a look.
