1) the action of blast
鼓风效应
2) ballooning effect
鼓胀效应
1.
Both sides of the inner pump barrel are located in the tubing liquid,so no pressure differential occurs on both sides of the inner pump barrel,thus eliminating the "ballooning effect" existing in conventional pumps and fundamentally reducing the pump leakage.
该抽油泵由内泵筒、外泵筒、连通孔、柱塞和固定阀连接而成,内泵筒的内外侧均处在油管内液体之中,内泵筒的内外侧不存在压差,消除了常规抽油泵的"鼓胀效应",从根本上减少了抽油泵的间隙漏失。
3) workable blast
有效鼓风<冶>
6) working minimum blast
