What is the difference between double suction pump and Horizontal center open pumps?
In the pump industry, double suction pumps and Horizontal center open pumps are often mentioned, and in fact, there is no essential difference between the two, they are actually different names for the same pump. In order to explain this more clearly, Zoomlian Pump Industry, the manufacturer of Horizontal center open pump, can explain this problem from the following aspects.
First,Definition and structure
Double suction pump: usually known as horizontal open double suction centrifugal pump, its structure is characterized by a horizontal open pump shell, with two symmetrical suction inlet, respectively located on both sides of the pump shell. This design allows the pump to balance axial forces while operating, reducing vibration and noise.
Middle open pump: also known as single-stage double suction centrifugal pump, its structure also has the characteristics of horizontal open pump shell, and also has two symmetrical suction inlet. From the structural point of view, the middle pump and the double suction pump are almost exactly the same.
Second, the working principle
The working principle of the double suction pump and the middle open pump is based on the role of centrifugal force. When the pump shaft rotates, the liquid in the impeller is thrown out, forming a certain pressure, so as to achieve the delivery of liquid. Due to the two symmetrical suction inlet, both pumps can inhale liquid from both directions at the same time, improving the suction efficiency.
Third, performance and application
Double suction pump and middle open pump are similar in performance, and are suitable for conveying large flow and high head liquids. They are widely used in water conservancy, electric power, chemical industry, urban water supply and other fields, especially in the need of large flow transport occasions.
Because these two kinds of pumps have the advantages of compact structure, smooth operation and easy maintenance, they have been widely recognized and used in industrial applications.
Fourth, Origin of name
The name "double suction pump" mainly emphasizes the characteristics of its two symmetrical suction inlet.The "middle open pump" is more based on its structural characteristics, that is, the pump shell is horizontally opened, which is easy to install and maintain.
In short, the difference between the double suction pump and the middle open pump is mainly the difference in name, and this difference is more based on the different characteristics or structure of the pump emphasis. Therefore, in practical applications, we can regard double suction pump and middle open pump as different names for the same pump.
