Working flow of centrifugal pump

Working flow of centrifugal pump

The main flow components of the centrifugal pump are the suction chamber, the impeller and the pressure chamber. The suction chamber is located in front of the water inlet of the impeller and plays the role of guiding the liquid to the impeller; the pressure water chamber mainly has three forms of spiral pressure water chamber (volute type), guide vane and space guide vane; The important working element is the heart of the overcurrent component. The impeller consists of a cover plate and a blade in the middle.

 

This article contains the following:

  • What is centrifugal pump

  • Working flow of centrifugal pump

  • Application range of centrifugal pump

 

1.What is centrifugal pump

The centrifugal pump works by rotating the impeller to cause centrifugal movement of water. Before starting the 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 perform high-speed rotational movement. The water undergoes centrifugal motion and is thrown toward the outer edge of the impeller. The channel flows into the pressurized water pipeline of the pump.

 

2.Working flow of centrifugal pump

Before the centrifugal pump works, first fill the pump with liquid, and then start the centrifugal pump. The impeller rotates quickly. The blades of the impeller drive the liquid to rotate. When the liquid rotates, it flows to the outer edge of the impeller by inertia. At the same time, the impeller sucks the liquid from the suction chamber. In this process, the liquid in the impeller flows around the blades.

In the flow around the liquid, the liquid exerts a lifting force on the blade. In turn, the blade acts on the liquid with a force equal to this lift and in the opposite direction. This force does work on the liquid, so that the liquid gets energy and flows out of the impeller. At this time, the kinetic energy of the liquid Increase with pressure energy.

The centrifugal pump relies on the action of the rotating impeller on the liquid to transfer the mechanical energy of the prime mover to the liquid. Due to the action of the centrifugal pump, when the liquid flows from the impeller inlet to the outlet, its speed energy and pressure energy are increased. The liquid discharged by the impeller passes through the pressure chamber, and most of the speed can be converted into pressure energy, and then transported along the discharge pipeline Go out.

At the inlet of the impeller, a vacuum or low pressure is formed due to the discharge of liquid. The liquid in the suction tank is pressed into the inlet of the impeller under the action of the liquid surface pressure (atmospheric pressure). .

 

3.Application range of centrifugal pump

Centrifugal pumps can be widely used in power, metallurgy, coal, building materials and other industries to transport slurry containing solid particles. Such as thermal power plant hydraulic ash removal, metallurgical beneficiation plant slurry transportation, coal washing plant coal slurry and heavy medium transportation When the centrifugal pump works, the pump needs to be placed on the land, the suction pipe is placed in the water, and the irrigation pump needs to be started. Due to structural constraints, mud pumps and submerged centrifugal pumps need to be placed on the water surface during operation. The pump must be placed in water, so it must be fixed. Otherwise, the motor will fall into the water and the motor will be scrapped. Moreover, because the length of the long shaft is generally fixed, the installation and use of the pump is cumbersome, and the application occasions are subject to many restrictions.
