Reciprocating pump flow regulation is an important task, but in everyday use, consumers tend to ignore the reciprocating pump flow regulation, and then introduce you to the small series reciprocating pump flow adjustment considerations. Reciprocating Pump Flow Regulation_Reciprocating Pump Flow Regulating Considerations Reciprocating Pump Flow Regulating Considerations Reciprocating Pump Flow Regulating Note that the discharge pressure of the reciprocating pump is independent of the structure size and speed and the maximum discharge pressure depends only on the pump's own power, strength, and sealing performance . Electric reciprocating pump flow almost nothing to do with the discharge pressure, but at high pressure, due to the gas contained in the liquid dissolved in the liquid, valve and packing leakage and other reasons, the pump flow slightly changes. Therefore, the reciprocating pump can not adjust the flow by closing the outlet valve. When the discharge valve is closed, the motor will be overloaded or the pump will be damaged due to the rapid increase of discharge pressure. Reciprocating pump with self-suction pump reciprocating pump without starting before the pump, will be able to inhale liquid. However, in actual use, the liquid in the pump cylinder is still expected to be used. On the one hand, the liquid can be sucked and discharged immediately; on the other hand, dry friction between the piston and the liquid cylinder or plunger (piston rod) and the filler can be avoided to reduce wear. Reciprocating pump suction capacity and speed, the speed is increased, not only to increase the loss of flow, and inertia loss also increases, causing suction pump pressure drop. When the pump cylinder pressure is lower than the liquid vaporization pressure, part of the liquid will begin to vaporizer in the cylinder, so that the pump inhalation fullness decreases, and even cavitation. Severe cavitation will lead to water hammer, so that pump parts damaged, shorten the life of the pump. Reciprocating pump flow control there are many ways, the above content would like to help you oh. (Editor: Le Luan Juan)
