Submersible pump maintenance matters and matters needing attention in operation

What are the considerations for selecting submersible pump?

submersible pump how maintenance?

1. Electrical aspects

Let's talk about electrical issues. If you want to perform electric maintenance on the submersible pump, you need to check the working voltage and current of the submersible pump. Only when the working voltage and current of the submersible pump are in a normal state, the submersible pump can work normally, otherwise it will appear Certain failures may even pose a threat to the human body.

Submersible pump maintenance matters and matters needing attention in 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 and form a good habit of regular inspection. Before using the submersible pump, everyone should check the sensitivity of the thermal relay equipped. In addition, We also need to see if other protection measures can work normally. If not, repair them in time to prevent further hidden dangers.

2. Mechanical aspects

When it comes to maintaining stainless steel submersible pumps, we must not ignore mechanical problems. According to common sense, submersible pumps have certain mechanical sealing performance and should be checked in time. If the mechanical seal of fountain pump fails, it is recommended to repair it immediately. In addition, it also depends on whether the oil hole is short of oil. If there is a lack of oil, it should be replenished immediately to prevent affecting the operation. In addition, it is recommended that you use oil. Inferior oil will also affect the operation, you can replace the new oil.

Stainless steel submersible pump manufacturers: submersible pump operation process need to pay attention to what?

(1) Pay attention to the sound and vibration of the submersible pump. If the sound of the unit is abnormal or there is a large vibration, stop and check the cause to prevent accidents.

(2) Pay attention to the position of the pointer of the instrument at any time. If there is any sudden change, check the reason. Normally, when the reading of the vacuum gauge suddenly rises, it is likely that the water level of the inlet pool drops too low or the inlet pipe is blocked by debris. The sudden drop in the reading of the pressure gauge is probably caused by the decrease in the speed of the power machine or the suction of air in the pump. After finding the reason, find a way.

(3) Stainless steel submersible pump manufacturers often check the temperature and lubrication of bearings. For bearings lubricated with oil rings, attention should be paid to whether the oil rings rotate flexibly, add bearing oil in time, and maintain a proper amount of oil. Too much or too little oil will heat up and the oil quality should be clean. Under normal circumstances, sliding bearings 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 stuffing box is normal. Water keeps dripping from the stuffing (usually about 30 drops per minute). If there is too much or too little, adjust the gland screws to make the stuffing properly compact.

(5) Always check the inlet pipe and stuffing box for air leakage. When there is air leakage, the reading of the pressure gauge will drop, and the submersible pump will have abnormal noise. Measures should be taken to prevent air leakage; otherwise, the water output will be reduced, and there will be no water in severe cases.
