Subsurface Inserted Sucker Rod Pump Double valve For Oil production
Subsurface Sucker Rod Pump Manufacturer With Long History
Subsurface sucker rod pump description:
For the deep well, Puyang Zhongshi researched and develop the suspension pump. This pump barrel uses a suspension structure, thus it improves the load bearing structure and makes the pump work in the deep well. The setting depth of pump could be 500-1500 meters deep.
This pump has the following characteristics: to prevent bending, the pump uses the gap bridge structure, the barrel is suspended in the outer section and does not bear any pressure thus, not easy to bend.
The space between the plunger and barrel reduces eccentric wear thus, extended the service life and guarantee improved pump efficiency. To prevent loss, the related eccentric distance ε=0. This eccentric distance between barrel and plunger reduce pump loss. This pump is suitable for the deep wells, which where one needs to hang more tail pipes.
