正排量泵（Positive Displacement Pumps）主要用于一些特殊应用，例如泵送粘性液体或含有悬浮颗粒或易碎固体的液体。这些泵通常无法像离心泵那样实现高流量，但它们能够产生更高的压力。正排量泵的工作原理 正排量泵通过捕获固定体积的流体并将其强制（排量）到排出管道或系统中来实现流体的移动。一些正排量泵在吸入侧使用...
Positive displacement pumps are batch delivery, periodic energy addition devices whose fluid displacement volume (or volumes) is set in motion and positively delivers that batch of fluid from a lower to higher pressure irrespective of the value of that higher pressure. ...
Positive displacement (PD) pump technology has endured decades of process challenges and substances, becoming a versatile choice among professionals for its consistent performance and robust nature. Positive displacement pumps operate by pulling in fluid, trapping a fixed amount within a chamber and then...
Positive Displacement Pumps Introduction tutorial to positive displacement pumps basic operating principles. A Positive Displacement Pump has an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pumps as the cavity on the suction side expands and...
