Reciprocating pump flow control _ Reciprocating pump flow control method

Reciprocating pump flow control is very important, the reciprocating pump can not reduce the outlet valve to regulate the flow rate, it will waste energy, and even cause the driver overload. Xiaobian today introduce you to the reciprocating pump flow adjustment method. Reciprocating pump flow control _ Reciprocating pump flow control method Reciprocating pump flow control methods are the following four: First, the bypass pump bypass adjustment set by the bypass pipe, regulating the size of the opening of the bypass valve, the liquid discharged to the suction pipe to adjust Pump discharge tube flow. The electric reciprocating pump should be set safety valve, when the exhaust pipe pressure is high, the safety valve opens, so as not to pump and prime mover overload. Second, change the pump speed From the reciprocating pump flow formula can be seen, the use of variable speed motor pump speed can be adjusted to achieve the purpose of traffic. Third, change the piston or plunger stroke (stroke) Change the eccentricity, plunger air travel, connecting rod length and position of linkage to change the piston or plunger stroke to change the pump flow. Fourth, open the top of the suction valve to adjust the flow motor reciprocating pump can be used to open the pump suction valve, the suction cylinder liquid in the return stroke from the suction valve back to the suction tube, thereby reducing the discharge flow. Reciprocating pump flow control must grasp the method, I hope the above description of the reciprocating pump flow adjustment method for your help. (Editor: Li Juan)
