The submersible pump has a wide range of uses, and it is used in various industrial, agricultural and domestic water transportation. Before using the submersible pump, we need to understand its related common sense to avoid unnecessary losses:
1. The submersible pump cannot be dehydrated. Test run under anhydrous conditions, the time should not exceed 5 minutes. During the pumping process, if the water level continues to drop, be careful not to allow the pump body to work above the water surface.
2. It cannot be restarted immediately after it is stopped. It can be started only after the water in the pipe has returned to completion. If there is no water after starting, stop the machine immediately to find out the cause and eliminate it.
3. It should be used near the specified head; the inner diameter of the matching rubber tube, iron tube or canvas tube should meet the technical requirements.
4. When the submersible pump is placed in the water or raised to the surface, the lifting rope needs to be pulled, not the cable. If you want to transport, disassemble or overhaul, you should cut off the power first.
5. When diving into the water, it should be lifted vertically, not lying down, let alone sinking into the mud.
6. Submersible pumps should not be started frequently. When in use, the outside of the pump can be covered with bamboo net or barbed wire to prevent weeds from blocking the grid of the submersible pump or jamming the impeller of the pump.
7. After starting up, if the impeller is reversed (the water output is greatly reduced or no water is discharged), the machine should be shut down immediately, and any two phases of the three-phase core wire in the cable should be exchanged to make it rotate positively.
8. It can be controlled by a water pump control cabinet. If there is no such equipment, a three-phase knife switch can also be used, but an electric fuse must be installed.
