Working Principle of Centrifugal Pump

Le 31 mars 2014, 10:40 dans Humeurs 0

Centrifuge is now widely use and the main working principle of centrifugal pump is using the centrifuge to work.

Firstly, the impeller is rotating by driving the pump shaft, doing work on the blade between the fluids by the centrifugal effect, and thrown to outside from the centre of the impeller. The speed is too high when the fluid reaches to the outside of the impeller.Find more infomation about mission pump , contact us.

Secondly, the liquid thrown from the blade is collected by the pump shell, and the liquid in the shell follow to the expansive direction by the shell channel, which makes the fluid kinetic energy is converted to static pressure and reduce the loss of the energy. So the function of the pump shell is not only collected liquid, but also an energy conversion device.

Thirdly, the principle of absorbing the liquid suction with a high-speed rotating impeller, which forces the liquid in the center, be discarded at a high-speed of the impeller, in order to form a low pressure in the center of the impeller, and absorb the liquid continuously from the low tough. If a centrifugal pump is full of gas before starting, a large enough vacuum formation cannot be formed when the gas is thrown down in the center after starting the impeller, so that liquid cannot be sucked in the tank, such a kind of phenomenon is called air bounding. We offer you sand pump at your service.

In order to prevent the phenomenon of air bounding happened, it must be filled with liquid before starting the centrifugal pump, this step called irrigation pump operation. And to stop the liquid injection pump shell follow into the low slot by gravity, should equip with check valve at the entrance of the pump suction line. If the position of the pump is lower than the liquid surface of the slot, without irrigation pump when it starts.

Fourthly, install guide roller around the impeller, which makes high energy conversion efficiency of the liquid in the centrifugal pump. Roller is a ring with a leaf in peripheral impeller. The bending direction of the blade is opposite to the bending direction of the impeller, its bending angle is corresponding to the direction of the liquid flow from the impeller, which guide liquid change its direction smoothly in the pump shell, make the loss of energy reduce to the bottom out and improve the efficiency of dynamic pressure to be converted to static pressure. We provide you brant screen for your disposal.

Fifthly, the balance hole of the back shroud eliminates axial thrust. The liquid pressure which has left the peripheral impeller is high, some osmoses to the behind of the back shroud, and the low pressure is formed at the liquid entrance of the side of the impeller, which creates thrust to push pump impeller inlet side of the axial thrust. This will be easy to cause loss of it, if it is seriously, vibration can be produced. The pressure difference in front of and behind the impeller will be reduced if the balance hole makes some of high-pressure liquid leak to the low pressure area, but this may cause low centrifugal pump efficiency.

Several Basic Types of Centrifuges for Liquid Filtering

There is a famous law that centrifugal force contributes to separate the various materials apart in a special machine which is making the circuit itself at a high speed. The container can be considered as a cylinder in some sense. It may immediately pop up in your head some complex machine with high technology related to the centrifuge force like 518 centrifuge on the construction sites. That’s a good phenomenon which means you get the right principle of the centrifuge. But it is actually also very common in your daily life, because there are so many types of the centrifuge of its own.We offer you sand pump at your service.

 

Actually the centrifuge has been invented two centuries ago. With the rapid development of the science technology, the centrifuge has also grown into some advanced design and used in wider areas. There are two main parts of all the centrifuges: a cylinder and axis. It can turn circles in the same way keeping the fast speeds. 518 centrifuge is a good example in the industries. Some of them are used vertically, while some are horizontally. But the working principle has never changed ------ with the high speed ultracentrifuge. It is important to get to know the relationship with the gravities basis. We offer you mongoose pt screen at your service.

 

Except for the centrifuge see in the construction sites there are a lot of types of the centrifuge. Swing-bucket is a well-known centrifuge in the field. It is usually made with a volume not too big. It is actually fine in the work. And the rate-zonal and isopycnic can be said as the two major categories of the rotors. The distance is so long that the separation sometimes is really need. Another type of the centrifuge is fixed-angle rotors. It isn’t difficult to understand the theory of the machine with such name. It is usually pelleting the applications to that particles or the collection on the connection of the machine.

 

Vertical is also an important branch of the centrifuge, which is much more professional in some sense. It is usually used in the developed and official places like large-scale hospitals and research laboratory, such as banding DNA in cesium chloride. It is a fine machine to do the work of the certain short distance. It is virtually more specialized and innovative than other kinds. There are also some good centrifuges of certain type like 518 centrifuge which make good use of the .basic centrifugal force in the fundamental process. And there is no need to say the normal use of the centrifuge to filter the liquid in different density. The work of the separating one liquid from the other can be done efficiently. And certainly the centrifuge is used in so many large industrials and carnival rides to space research. We offer you stack sizer at your service.
