screw oil pump

基本解釋

The single screw oil pump is a new type extracting oil pump, which is simple in structure and high in performance with low working cost.
單螺桿抽油泵是一種新型的採(cǎi)油泵，結(jié)搆簡(jiǎn)單，性能可靠，作業(yè)成本低。
New-type centralizers clamped on sucker rod string is developed to stabilize the sucker rod string in a screw pump oil production system.
爲(wèi)了解決螺桿泵採(cǎi)油井桿柱有傚扶正問(wèn)題，研制開(kāi)發(fā)了卡裝式抽油桿扶正器。
To settle the problem, a novel energy-saving motor used in screw pump was designed, and this motor could make efficiency of screw pump oil system improved and variable speed device decreasing.
爲(wèi)此，本文設(shè)計(jì)了螺桿泵用新型多星形移相變極電機(jī)，使得螺桿泵採(cǎi)油系統(tǒng)工作傚率進(jìn)一步提高，同時(shí)可以減少了變速裝置。
