Different references
1. Centrifugal pump: refers to a pump that transports liquid by the centrifugal force generated by the rotation of the impeller.
2. Submersible pump: It is an important equipment for deep well water extraction. When in use, the entire unit submerges in the water to extract groundwater to the surface.
Different principles
1. Centrifugal pump: It works by using the rotation of the impeller to cause the water to undergo centrifugal motion. Before starting the water pump, the pump casing and the suction pipe must be filled with water, and then the motor is started so that the pump shaft drives the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows into the water pressure pipeline of the water pump through the flow channel of the volute pump casing.
2. Submersible pump: The motor and the water pump are directly connected through a claw or single-key barrel coupling; equipped with three-core cables of different specifications; the starting equipment is an air switch and auto-coupling pressure reducing pneumatic actuator of different capacity levels, the water pipe is made of steel pipes of different diameters, flange connection is adopted, and the high-lift electric pump is controlled by a gate valve.
Different scopes of application
1. Centrifugal pump: widely used in power, metallurgy, coal, building materials and other industries to transport slurries containing solid particles. Such as hydraulic ash removal in thermal power plants, ore slurry transportation in metallurgical ore dressing plants, coal slurry and heavy medium transportation in coal washing plants, etc.
2. Submersible pump: Submersible pumps are used for hot spring bathing, and can also be used to extract groundwater from deep wells, and can also be used for water extraction projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and water for people and livestock in high mountainous areas. It can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage.
