Our company is a professional submersible pump manufacturer. When customers choose submersible pumps, our pump manufacturer will provide pre-sales services such as submersible pump models and prices for customers' reference. Our pump manufacturer can provide customized pump products for customers.
Submersible pumps are widely used in various industrial, agricultural, and domestic water transportation. Before using submersible pumps, we need to understand their relevant knowledge to avoid unnecessary losses:

 

 

1. Submersible pumps cannot operate without water. They should be tested under anhydrous conditions for no more than 5 minutes. During the pumping process, if the water level continues to drop, it is important to note that the pump body should not work above the water surface.

2. After shutdown, it is not possible to restart immediately. It is necessary to wait until the water in the pipeline has returned. If water cannot be discharged after startup, the machine should be stopped immediately to identify the cause and eliminate it.

3. It should be used near the designated elevator; The inner diameter of the matching rubber pipe, iron pipe or canvas pipe should meet the technical requirements.

4. When the submersible pump is placed in water or raised from the surface, grab the lifting rope and do not pull the cable. If it needs to be transported, disassembled or repaired, the power should be cut off first.

When diving, it should be lifted vertically, not lying down, and not sinking into the mud.

6. Submersible pumps should not be started frequently. When the pump is in use, bamboo or wire mesh can be used outside to prevent weeds in the water from blocking the mesh holes or impeller of the submersible pump.

7. After starting up, if the impeller reverses (resulting in a significant decrease in water output or no water output), immediately stop the machine and replace any two phases of the three-phase core in the cable to allow water output.

8. Pump control cabinet can be used for control. If this equipment is not available, a three-phase knife switch can also be used, but an electric fuse can be installed.

 

Functional characteristics of submersible pumps

 

Submersible pumps are suitable for fire protection engineering in power plants, factories, high-rise buildings, residential buildings, hotels and other buildings.

After being combined with a submersible pump and submersible motor, it can work underwater and has the advantages of simple structure, small size, light weight, and easy installation and maintenance. It operates safely, reliably, and energy-saving.

The submersible sewage pump is designed with large channel anti blocking hydraulic components, which can effectively pass solid particles with a diameter of 25-70 mm.

Reasonable design, anti clogging, strong winding ability, and reliable use.

 

 

Using new materials for sealing, the pump can operate safely and continuously for more than 8000 hours.

Compact structure, easy to move, simple installation, no need to build a pump room, can reduce project costs.

The dual rail automatic installation system brings convenience to installation and maintenance, and workers do not have to enter the sewage pit for this.

The float switch can automatically control the start and stop of the water pump according to the required water level changes, without the need for a dedicated person to supervise.
