Reciprocating pump regulates flow It is not possible to adjust the flow by reducing the size of the outlet valve, as this can result in wasted resources and even damage to the reciprocating pump. Reciprocating pump flow control methods, there are generally the following: Reciprocating pump to adjust the flow method First, bypass adjustment Reciprocating pump set reciprocating pump bypass pipe, regulating the size of the opening of the bypass valve, the liquid discharged back to the suction pipe, the past Complex 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, to change the reciprocating pump speed reciprocating pump flow from the formula can be seen, the use of variable speed motor reciprocating pump speed, you can achieve the purpose of regulating the flow. Third, change the reciprocating pump piston or plunger stroke (stroke) to change the eccentricity, plunger air travel, connecting rod length and position of the link mechanism to change the piston or plunger stroke to change the reciprocating pump flow. Fourth, open the top of the reciprocating pump to adjust the flow motor can be used to open the top of the pump suction valve so that the liquid inhalation cylinder in the return stroke from the suction valve back to the suction tube, thereby reducing the reciprocating pump discharge flow.
