The crux of the matter should proceed from the fundamental and thorough solution to pump in a sealed, overload and other problems, this is a more proactive approach.
问题的关键应该是从根本着手，彻底解决泵在密封、过载等方面的问题，这才是一种较为主动的办法。
Screw pump body and at the same time, each other between the screw and screw and form a sealed chamber, ensure airtight, otherwise there may be liquid backflow from the gap.
同时螺杆与泵体、螺杆与螺杆间又相互形成密封腔，保证密闭，否则就可能有液体从间隙中倒流回去。
Accumulator Tank: a sealed air chamber combined with a water reservoir provides expansion volume to reduce pump cycling from minor pressure changes and give a steady flow.
压力鼓：你个密封的空间结合水箱来提供充足的空间来减少泵循环时较小的压力改变和稳定的水流。
