Advantages and Disadvantages of Self-priming Pump and Submersible Pump
source:Industry News release time:2021-03-18 Article author:Rosit Popular:Air band saw
The main part of the self-priming pump is located above the water surface for easy maintenance. The load distribution is relatively uniform, and the mechanical load per unit area is small. The lifting height is small, and the pump room is low,so there is no need to move the power machine when disassembling.The total cost of self-priming pumps, transmissions and power machines is cheaper.
However, the installation area is large, and the area of the machine room is large.It needs to be filled with water for the first time,the operation is complicated, and it is not easy to automate.The sealing requirements of the water inlet pipe are relatively strict and the air cannot be sucked into the pump. The radial load requires high reliability of the bearing.
The installation area of the submersible pump is small, the impeller is located underwater, and the suction performance is better. Therefore, it can be used at a higher speed and does not need to be filled with water to start, which is convenient for automation. The submersible pump with small size and light weight can also be moved and used easily, and it is convenient to carry.
However, the main part of the submersible pump is located below the water surface,which is inconvenient to maintain.The mechanical load is concentrated, the load per unit area is large, and the maintenance of water-lubricated bearings is inconvenient.
