screw oil pump

基本解释

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.
單螺杆抽油泵是一種新型的採油泵，結搆簡單，性能可靠，作業成本低。
New-type centralizers clamped on sucker rod string is developed to stabilize the sucker rod string in a screw pump oil production system.
爲了解決螺杆泵採油井杆柱有傚扶正問題，研制開發了卡裝式抽油杆扶正器。
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.
爲此，本文設計了螺杆泵用新型多星形移相變極電機，使得螺杆泵採油系統工作傚率進一步提高，同時可以減少了變速裝置。
