For the meter which has liquate inner, can work in strong vibration or pressure pulse situation.

对于在外壳内充液仪表，能够抗工作环境振较强和减少介质压力响。

The damping effect is also affected by pump pressure, volume of air chamber and the prefill pressure in chamber.

改变泵压、空气包容积和充气压力等参数,对排出液体衰减有较大响。

Fluid is conveied to bit nozzel through drill string from pump is a transient state flowing with pressure wave, which makes the fluid jetted out from nozzel has certain pulsation.

从钻井泵经过钻柱内部输送到钻流体是一种瞬态流，存在着压力行波，使从普通射出流体有一定程度。
