Piston pump mainly by the piston in the pumpcylinder for reciprocating motion to breathe and remove the liquid.
活塞泵主要由活塞在泵缸内作往复运动来吸入和排除液体。

Reciprocating pump flow and pressure head has nothing to do with the pumpcylinder size, and the reciprocating frequency of the piston stroke.
往复泵的流量与压头无关，与泵缸尺寸、活塞冲程及往复次数有关。

Three mutual engagement of the screw in the pumpcylinder for each lead of the formation of a sealed chamber, causing the seal between the suction mouth.
