hydraulic piston

基本解釋

However, someone thinks that the optimum oil recovery mode of Lunnan oilfield should be hydraulic piston pump.
但有人對(duì)此提出了不同意見(jiàn)，認(rèn)爲(wèi)該地區(qū)的機(jī)械採(cǎi)油應(yīng)首選水力活塞泵。
In chapter 2, a fixed high pressure single-phase water mist fire suppression system driven by water hydraulic piston pump is developed.
第二章，研制了由純水液壓柱塞泵敺動(dòng)的固定式高壓?jiǎn)蜗嗔骷?xì)水霧滅火系統(tǒng)。
At the initial stage of development, the main oil production methods give priority to hydraulic piston pump and closed hot water circulation.
開(kāi)發(fā)初期，主導(dǎo)開(kāi)採(cǎi)方式主要以“水力活塞泵、閉式熱水循環(huán)”等採(cǎi)油工藝爲(wèi)主。
