The pump moving back and forth has fine sucking in not only function, and there are still fine self attracts a function. Have no need of irrigation pump therefore , to the pump moving back and forth most, generally before starting. Machine efficiency height , energy conservation. Highhanded intercourse pump rate of flow The pump theory rate of flow: Qt = AsnZ Style is hit by Qt pump theory rate of flow。 A bar piston (or section of piston) area。 S route or distance of travel。 The n crank shaft rotation rate (or the bar piston every minute intercourse number of times) Z unites a number (bar piston or piston number) Actual pump rate of flow: Q = Qt－ Q. Style is hit by Q pump rate of flow。 Qt pump theory rate of flow。 The pump rate of flow loses Q. 3 The factor that the rate of flow bringing about a pump loses has: The volume bringing about since liquid presses or expands is lost。 The volume bringing about since the valve lags when being closed down is lost。 Since the valve closes the day afer tomorrow do not lose strictly, by sealing off the volume that leakage soft and floury brings about。 The volume by the fact that the bar piston , piston rod or the piston ring leakage bring about is lost. The pump microtime rate of flow Single cylinder Shan effect pump rate of flow curve: Qt Three jar Shan effects pumps rate of flow is the single cylinder Shan effect pump rate of flow overlying on three phases Whose curve as follows: Qt The pump power The pump ef
