Multi-stage pump power

[Asia Fluid Network News] Multistage pump is the use of large-area piston-driven piston in the small area to form a high-pressure gas pump. Can be used for compressed air and other gases, the output pressure can be steplessly adjusted by the driving pressure. With the rapid development of China's industrial level, the use of multi-stage pumps is becoming more and more widespread. The study of multi-stage pump parameters is very important for product use and research. Multi-stage pump Next, the main multi-stage pump power calculation formula. ρ: Density of the liquid conveyed by the multistage pump (kg / m3); γ: Gravity γ = ρg (N / m3) of the liquid conveyed by the multistage pump; g: Gravitational acceleration (m / s) Mass flow rate Qm = ρQ (t / h or kg / s). From the above parameters, the formula for calculating multistage pump power is: Pe = ρg QH (W) or Pe = γQH / 1000 (KW) There are many kinds of multistage pumps, but their working principles are basically the same , The structure is similar. A lot of multi-stage pump series, divided according to different appearances: vertical multi-stage pump and horizontal multi-stage pump. Divided according to different materials: stainless steel multi-stage pump, lg multi-stage pump, da multi-stage pump. With the different structures and materials caused by the different types, the study of its parameters is even more important. Although different in kind, its basic parameters are the same, and for multi-stage pumps their power calculation is the same. It also simplifies a lot of work and facilitates research.
