Spray metal grooved plunger oil well downhole pumps
Spray metal grooved plunger downhole pump Description
The rod pump is connected to sucker rod after being assemblied on the surface then it is pulled down to the well bottom through the tubing.
Thus it is convenient for the inspection and workover because they can be pulled up and down through the tubing and suitable for deeper well. The life span of tubing can be prolonged for decreasing the times of the thread of the tubingbeing turned on and off and the time of the workover.
Subsurface sucker tubing pump is applied to pumping crude oil from oil well with pumping unit and sucker rod. Through sucker rod,tubing pump is descent to certain depth of oil. When pumping unit drives sucker rod to move up and down, sucker rod drives plunger of subsurface sucker rod pump move up and down in tubing barrel and pump crude to surface.
