泵中复杂泵体由泵体、涡壳、进液管及盖板等部分组装而成。
The complex pump body in the pump is fabricated by that a pump body, a whorl casing, a liquid inlet pipe, and a cover plate are assembled.
通过推杆 的旋转使进液腔的体积增加，聚合物溶液通过自身压力进入。
The volume of liquid inlet chamber is increased through the rotation of push rod, and the polymer liquid enters through the self pressure.
进液阀芯和阀座，由于开启关闭比较频繁，液体流速高，密封很快就会失效。
Inlet valve and seat, due to open and close more frequently, the liquid flow rate is high, sealing will soon expire.
