双柱塞串联抽稠泵
简 介：
双柱塞串联抽稠泵是集防砂、防垢、防气功能于一体的特种抽油泵。柱塞采用分体设计，泵筒采用三段变直径串联设计，可降低固体颗粒进入柱塞与泵筒间隙的几率，同时在运行过程中可实现对泵筒内壁刮削与柱塞外表面自清理目的；强启闭式凡尔设计，有效降低在粘稠介质中杆柱的下行载荷，同时具有防气锁功能。
该泵适用于含砂、结垢、含气及稠油介质等类型的生产井。
This pump is a special pump which have the concentrative function of sand control 、 antiscale and prevent gas lock. The plunger adopt separate design and barrel have three sections of variable diameter series design, this can reduce the risk of the solid particles into clearance which formed by the pump barrel and plunger,meanwhile, this can achieve the aims of the pump barrel wall scraping and plunger surface self-cleaning in the running process;Strong open-close type valve design can effectively reduce the downward load in the viscous medium, this design also have the function of prevent gas lock at the same time.
The pump is suitable for the various type wells,such as sand production well , Including scale well,heavy oil well,hign gas well etc.
