Multistage Pump Power Calculation

multistage pump Power Calculation

multistage pumps are a type of centrifugal pumps that is driven by large-area pistons to form high-pressure gas in small-area pistons. Can be used for compressed air, and other gases, the output air pressure can be adjusted steplessly by driving air pressure. With the rapid development of World's industrial level, the use of multi-stage pumps is becoming more and more widespread. The study of the parameters of the multi-stage pump is very important for the use and research of the product.

Next, the power calculation formula of the multi-stage pump is mainly introduced.

ρ: The density of the liquid delivered by the multi-stage pump (kg/m3);

Y: The gravity of the liquid delivered by the multi-stage pump Y=ρg (N/m3);

g: Acceleration of gravity (m/s) mass flow Qm=ρQ (t/h or kg/s);

The calculation formula of multi-stage pump power is obtained from the above parameters: Pe = ρg QH (W) or Pe = YQH / 1000 (KW)

There are many types of multi-stage pumps, but their working principles are basically the same, and their structures are similar. There are many multi-stage pump series, which are divided into vertical multi-stage pumps and horizontal multi-stage pumps according to their appearance. According to different materials, it is divided into: stainless steel multistage pump, LG multistage pump, DA multistage pump. With the difference in structure and material, the study of its parameters becomes more important. Although the types are different, the basic parameters are the same. For multistage pumps, their power calculation methods are the same. This also simplifies a lot of work and facilitates research.
