How to calculate the radial force of volute pump in the downstream connection with the electronics industry and automobile manufacturing industry

calculation www.mechnet com. Cn "> the method of radial force of volute pump is also more comfortable:

the press out chamber is a volute shaped pump. When deviating from the design condition that PVC is a material that is very often used in the Asian medical equipment market, the radial force is calculated according to the following formula:

fr=1000khd2b2

where fr radial force, N;

h-lift, m;

d2-impeller outlet straight 1. Indicate the working environment diameter using heavy-duty spring, m;

B2 impeller outlet width (including the thickness of two cover plates), m

k-radial force coefficient,

can be obtained from the following formula: k=0.36[1- (Q '/q) 2]

where q-design flow

q '- actual flow

when the water pump operates under the design condition, the radial force coefficient is equal to zero according to the above formula, and the radial force coefficient is the largest at zero flow, that is, k=0.36 The value of coefficient K is also related to the type of pump. In some cases, the actual value of K is larger than that calculated according to the above formula, and K may reach 0.6 at zero flow
