Slowly close the running the pump outlet valve, at any time, turn on the pump outlet pressure, can be a little on the basis of two export cross-line valve as a return (excessive) to control pressure within the specified value

Closes the original movement pump outlet valve slowly, after pays attention to the ejector priming outlet pressure as necessary, may through micro open between two exportation the cross line valve to take the backflow (excessively), control pressure in rating

Run pump outlet valve slowly closes the original, always pay attention to starting after pump outlet pressure can be slightly open valve as a backflow cross between the two export lines (excess), controlling the pressure within the specified value
