【求助】什么叫single-strock-type pump？什么叫highly dampened reciprocating pump?

single-strock-type pump 单冲程泵
highly dampened reciprocating pump 强缓冲往复式泵?

尽管有了正确的中译, 我也不知那是什么。 Therefore, this is not a problem of language, but a matter of knowledge of machincal engineering.



= = = = = =

有趣的是, what is 泵? 这只是pump之译音 (也有译为“帮浦”)。 不过, “泵”已溶入现代汉字, 大家都理解“泵”is a mechanical device that moves fluid or gas by pressure or suction.

Reciprocating pump
http://en.wikipedia.org/wiki/Reciprocating_pump

A reciprocating pump is a positive displacement plunger pump. It is often used where relatively small quantity of liquid is to be handled and where delivery pressure is quite large.
Reciprocating pumps are used in High performance liquid chromatography (HPLC).
