Safety regulations for the use of submersible pumps
2023-12-15
The submersible pump should be installed in a strong basket before putting it into the water, or a strong protective fence can be set up around the pump in the water. The pump should be upright in the water, the water depth shall not be less than 0.5m, and it should not be used in the water containing a large amount of mud and sand.
1, submersible pump should be installed in a solid basket and then put into the water, can also be in the water around the pump set up a solid protective fence. The pump should be upright in the water, the water depth shall not be less than 0.5m, and it should not be used in the water containing a large amount of mud and sand.
2. When the submersible pump is put into the water or raised to the water surface, the power supply should be cut off first, and it is strictly forbidden to pull the cable or outlet pipe.
3, submersible pump should be installed to protect the zero and leakage protection device, work around the pump within 30m water surface, no people, livestock.
4. Check and confirm before starting:
(1) The water pipes shall be tied firmly.
(2) Screw plugs such as air release, water release and oil injection shall be tightened.
(3) The impeller and inlet joint shall be free of sundries.
(4) Good electrical insulation.
5. After the power is turned on, it should be tested first, check and confirm that the rotation direction is correct, and the operation time without water shall not exceed the provisions of the instruction manual.
6. The water level changes should be observed frequently. The distance from the center of the impeller to the horizontal should be between 0.5~3.0m, and the pump body should not be trapped in sludge or exposed to the water. The cable shall not rub against the well wall and pool wall.
7. The starting voltage shall conform to the provisions of the instruction manual. When the current exceeds the limit specified in the nameplate, the machine shall be shut down for inspection and shall not be switched on or off frequently.
8. When the submersible pump is not in use, it shall not be immersed in water for a long time and shall be placed in a dry and ventilated room.
9. The insulation resistance of the motor stator winding shall not be less than 0.5 MΩ.

Submersible pump installation and use of technical matters needing attention
Water Because the submersible pump unit is charged to dive into the water, the sealing and insulation performance of the motor must be reliable, and the installation and use technology must be strict. A little improper will cause problems, light will aggravate the wear of parts, heavy will burn the motor can not work. Therefore, the installation and use of submersible pump units must comply with the following technical points.

Submersible pump: pressurized water pump for domestic water supply
The self-filling and water absorption of the domestic water supply pump does not require the pump to be located below the lowest water level of the storage tank. The self-filling suction pump cannot be started at the lowest water level of the storage tank. Therefore, the storage tank should set a pump-starting water level according to the self-filling requirements of the pump. When the water level is above the pump-starting water level, the pump is allowed to start. When the water level is below the pump-starting water level, the pump is not allowed to start. However, the pump already in operation should continue to run and stop automatically when the pump reaches the minimum water level of the storage tank (as long as long as long as required, it can continue to operate even below the minimum water level). Therefore, the pump top discharge hole of the horizontal centrifugal pump and the first stage (section) pump body of the suction end of the vertical multistage centrifugal pump can be placed below the lowest design water level elevation.

How to effectively reduce the energy consumption of water pump
The internal surface of the water pump and the inner surface of the pressure water chamber (also known as the volute) are rusted and uneven. Surface corrosion bump will reduce the pump water volume by 7%-8%; Only steel brush and iron sandpaper or grinding wheel need to be polished smoothly during maintenance, which can reduce the fuel consumption or power consumption by 9%-14% during work.
