High pressure self balancing corrosion multistage centrifugal pump is mainly basic performance parameters

High-pressure self-balancing corrosion of multistage centrifugal pump performance parameters were used to characterize a set of pump performance data, the basic performance parameters of the flow rate Q, head, rotating speed of shaft power N, N, H efficiency eta parameters such as, at the same time, according to the different working conditions acquisition parameters, can develop the work performance curve, better convenient to analyze the water pump performance test. High pressure self balancing corrosion multistage centrifugal pump is the main performance of basic parameters are the following: a, flow Q

flow is to carry out pump in unit time the amount of liquid ( Volume or quality) 。

volume flow with Q, said units are: the m3 / s, m3 / h, l/s, etc.

mass flow with Qm, said unit is: t/h, kg/s, etc.

mass flow rate and the relationship between the volume flow is: the Qm

= rho Q type of rho - — The density of the fluid ( 公斤/立方米,t / m3) Rho, normal temperature water = 1000 kg/m3.

2, lift H

head pump is pumping unit weight of the liquid from the pump inlet ( suction flange) To the pump outlet ( outlet flange) The added value of energy. That is a Newtonian liquid through the effective pump energy. The unit is n. m/N = m, i. e. pump pumping liquid liquid column height, used meters for short. Three, rotational speed n

speed is the pump shaft revolutions per unit time, with the symbol n said the unit is the r/min.

4, NPSH NPSH

NPSH is also called net positive suction head, is said main parameters of cavitation performance. NPSH domestic used Δ h said.

5, power and efficiency of the pump power is usually refers to the input power, the power of the prime mover to spread on the pump shaft, shaft power, is expressed in p;

the effective power of the pump is also called the output power, expressed in Pe. It is a unit of time away from the water pump effective energy of liquid in the pump.

because head refers to the unit water pump output of heavy liquid obtained from the pump energy effectively, so the head and the product of the mass flow rate and the acceleration of gravity, is from the output of the pump unit time effective energy gained by the liquid - — Namely the effective power of the pump: Pe = rho gQH ( W) =γQH( W)

type of rho - — the liquid density ( kg/m3) ;

　　γ— — liquid heavy ( N / m3) ;

Q - — flow ( 立方米/秒) ;

　　H— — lift ( m) ;

　　g— — The acceleration of gravity ( m/s2) 。

shaft power p and effective power Pe inside the pump for the loss of power, the difference between the measured the size of pump efficiency. The efficiency of the pump for the effective power and the ratio of the shaft power, expressed in eta.
