摘要： An oil pump used in deep well especially a nc reciprocating immersible oil pump, which can integrate a power equipment and the oil pump and adjust the parameter on-line, comprises a balance sieve tube, a power equipment and the oil pump, all of which are immersed in the ground oil, wherein the power equipment comprises a stator having a seal chamber and a rotor including an iron core and installed in the stator, the stator and the rotor constitute a friction pair through a supporting sleeve and the rotor core. The upper end of the stator links to the lower end of the oil pump connecting an oil outlet tube, the lower end of the stator links to the sieve tube in turn. In this application a rod and an oil pump overground are not used, therefor the fixing time and the cost are reduced, at the same time the enegy cost are decreased too.

摘要： The invention relates to a new type of deep well pump apparatus, especially a numerically controlled reciprocating submersible pump apparatus having a drive integrated with a pump freely adjusting parameters online any time. The whole apparatus, including a balancing sieve tube, a drive and a pump, is submersed in underground oil reservoirs. The drive consists of a stator with an airtight cavity and a reciprocating head with iron cores inside the stator. The stator and the reciprocating head form a friction couple via the supporting guides and the reciprocating head iron cores. The stator's upper end is connected to the pump's lower end through the sieve tube. An oil tube is connected to the pump. The stator's lower end is connected to the balancing sieve tube, end plug and end coupler serially. The invention is a combination of the drive and the pump, adjusting working parameters online any time, eliminating the nodding donkey and rods, reducing installation time and cost, saving large investment, energy and avoiding many disadvantages of the traditional oil extraction equipment.
