Rotary valve with airlock’s calculation formula

- Apr 04, 2020-

V(m3/h)=V1(L/rev)xN(rpm)x60x η(%)

G(T/h)=V(m3/h)xρ(T/m3)xK

V:discharging capacity(m3/h) V1: Rotor volume per revolution(L/rev)

N: rotor speed per minute(rpm) η:Volume efficiency of rotor(%)

ρ:material’s bulk density(T/m3) K: correction factor usually is 0.7~0.8

The above formula is the general one. We will adjust the specific data as per actual working condition.
