What are the precautions for choosing a submersible pump?

How to maintain the submersible pump?

1. Electrical aspects

Let's talk about electrical problems, if you want to carry out electric maintenance of the submersible pump, you need to check the working voltage and current of the submersible pump, only the working voltage and current of the submersible pump are in a normal state, the submersible pump can work normally, otherwise there will be certain failures, and even pose a threat to people.

Submersible pump maintenance matters and precautions for operation

We all know that the submersible pump has a thermal insulation resistance to the ground, after a period of use, it is necessary to check, develop a good habit of regular inspection, before using the submersible pump, everyone should check the sensitivity of the thermal relay equipped with, in addition, we also have to see if other protective measures can work normally, if not, repair in time to prevent further hidden dangers.

2. Mechanical stainless

steel submersible pump manufacturers when it comes to maintaining stainless steel submersible pumps, we must not ignore mechanical problems, according to common sense, submersible pumps have certain mechanical seal performance, to check in time, if the mechanical seal of the fountain pump fails, it is recommended to repair it immediately, in addition, it is necessary to see whether the oil hole is short of oil, if there is a lack of oil, it should be replenished immediately to prevent the operation of the operation, in addition, it is recommended that you use engine oil, inferior oil will also affect the operation of the instrument, if necessary, you can replace the new oil.

Stainless steel submersible pump manufacturers: what should be paid attention to during the operation of submersible pumps?

(1) Pay attention to the sound and vibration of the submersible pump, if you find that the sound of the unit is abnormal or has a large vibration, you should stop to check the cause to prevent accidents.

(2) Pay attention to the position of the instrument pointer at any time, if there is any sudden change, check the reason, under normal circumstances, when the reading of the vacuum gauge rises suddenly, it is likely that the water level of the inlet pool drops too low or the inlet pipe is blocked by debris, and the reading of the pressure gauge drops suddenly, it is likely to be caused by the decrease in the speed of the power machine or the inhalation of air in the pump.

(3) stainless steel submersible pump manufacturers often check the temperature and lubrication of the bearing, for the bearing lubricated by the oil ring, pay attention to whether the oil ring rotation is flexible, add bearing oil in time, maintain the appropriate amount of oil, too much or too little oil will be heated, the oil quality should be clean, under normal circumstances, the sliding bearing should be replaced every 200-300 hours, but the number of oil changes should be reduced every six months, the rolling bearing should be checked and supplemented after 1500 hours of operation, and the new water pump should be replaced in advance.

(4) Pay attention to whether the packing box is normal, the water continues to drip out of the filling (generally about 30 drops per minute), if too much or too little, the gland screw should be adjusted to make the filler properly compressed.

(5) Always check whether the water inlet pipe and stuffing box are leaking, when there is air leakage, the reading of the pressure gauge will drop, and the submersible pump will have abnormal noise, and measures should be taken to prevent air leakage; Otherwise, the amount of water produced will be reduced, and in severe cases, there will be no water.
