The submersible motor drives the shaft of ESP and the impeller on the shaft to rotate at a high speed. The liquid filled in the impeller is forced by the centrifugal force to the periphery of the impeller through the impeller flow path, so that the pressure and the speed are simultaneously increased, and the lift is obtained superimposed one by one, lifting the well fluid to the ground.
1.Wide displacement range, the range from 30m3 to 3500m3 per day.
2.High lift, the maximum lift is up to 4000m.
3. It is convenient to maintain and adjust. After the change of output of the oil well, the adjustment frequency can meet the needs of the oil well.
4.There are no moving parts on the ground, which is much safer than pumping unit, and there is no oil leakage at the wellhead.
5.Solve the problem of eccentric wear between rod and tubing in deep well application, prolong pump inspection cycle and save operation cost.
