What are the considerations for choosing a submersible pump?

How to maintain the submersible pump?

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 Certain failures may even pose a threat to the human body.

Submersible pump maintenance and operation precautions

We all know that the submersible pump has a thermal insulation resistance to the ground. After using it for a period of time, it is necessary to check it and develop a good habit of regular inspection. Before using the submersible pump, everyone should check the sensitivity of the thermal relay equipped. In addition, We'll also see if other protections work properly, and if not, fix them in time to prevent further hidden dangers.

2. Mechanical aspects

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 and should be checked in time. If the mechanical seal of the 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 it is short of oil, it should be replenished immediately to prevent it from affecting the operation. In addition, it is recommended that you use oil. Poor quality 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 it is found that the unit has abnormal sound or large vibration, stop the machine to 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 cause. Usually, when the reading of the vacuum gauge suddenly rises, it is likely that the water level in the inlet pool is too low or the inlet pipe is blocked by debris. , The sudden drop in the pressure gauge reading is likely to be caused by the reduction in the speed of the power machine or the suction of air in the pump. After finding the cause, find a way to eliminate it.

(3) Stainless steel submersible pump manufacturers often check the temperature and lubrication of the bearing. For bearings lubricated with oil rings, pay attention to whether the oil ring rotates flexibly, add bearing oil in time, and maintain an appropriate amount of oil. Too much or too little oil It will heat up and the oil quality should be clean. In general, 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 replenished after 1500 hours of operation. Change.

(4) Pay attention to whether the stuffing box is normal, and the water keeps dripping from the stuffing (generally about 30 drops per minute). If there is too much or too little, the gland screw should be adjusted to make the stuffing properly compressed.

(5) Always check whether there is air leakage in the water inlet pipe and stuffing box. 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 in severe cases, it will Anhydrous.
