一种隔离式柱塞泵的研究与应用——呼吸管柱塞泵

Study on the Theory and Application of an Isolating Plunger Pump——Plunger Pump with Air Tube

呼吸管柱塞泵是一种专门输送渣浆颗粒介质的柱塞泵,它比普通的柱塞泵增加了一个进液阀和呼吸管,借助干净介质将输送颗粒介质与柱塞腔隔离开,使柱塞、柱塞密封工作在干净介质的环境中,从而延长了柱塞泵的使用寿命,提高了工作压力、降低了制造成本。

The plunger pump with air tube is a kind of plunger pump specially designed for transferring residual paste particulate medium. Compared with other plunger pumps, this pump has an additional fluid input valve and an air tube, taking the residual paste articulates medium from tnmk piston cavity with the help of clean medium, which enables the trunk piston and piston seal to work in an environment of clean medium, so that the service lifetime and operating pressure of the pump are increased, while the manufacturing cost is lowered.
