It is a positive displacement pump. It relies on the interference fit between the eccentrically moving rotor and the stationary stator to form a sealed cavity that is not connected to each other. Through the rotation of the rotor inside the stator, the sealed cavity extends axially from the inlet of the pump. The end moves to the outlet end, so that the medium in the sealed cavity can be transported by the pump.
This product has a simple design structure: adopts a two-stage reduction structure of the main drive, that is, the first stage of belt wheel reduction, and the use of tower wheels can achieve reduction ratios of 1.3 and 2.05; the second stage adopts a pair of spiral bevel gears for reduction, and the reduction ratio is 4.625 , And finally achieve a maximum reduction ratio of 9.48, which can meet the supporting use of different types of screw pumps.

A supporting slip for an oil field screw pump production well solves the problem that the original supporting slip cannot pass through a reduced-diameter well section. Specifically, it includes a main body on which slips and friction blocks are connected.

Torque anchor is an anti-drop tool specially designed for screw pump with reference to foreign advanced technology. Torque anchors have the characteristics of simple operation, firm anchoring, convenient use, safety and reliability.
The tubing rotator originally used in the eccentric test process string in the oil field is rotated through the steel ball between the upper and lower joints, and can rotate 360° arbitrarily. However, with the improvement of the process, the tubing rotator is required to stop after turning N turns (usually 3 turns), and vice versa. This tubing rotator is applied to the screw pump oil extraction eccentric test process pipe string, installed on the upper part of the screw pump, and used in conjunction with the eccentric wellhead. When working, the upper joint faces up and the lower joint faces down to connect to the pipe string and follow the pipe. When the column is lowered into the well, the tubing can be rotated under pressure while the pump body is anchored, which can solve the problem of tubing loosening caused by the reaction torque when the screw pump stops during the production process, and can also solve the problem of tubing loosening during the test process. The contradiction between twisted test cables.
The screw pump polished rod plugging device is a safety sealing device that blocks the inner cavity of the tubing during the oil production operation in the oil field. During the operation of the pumping unit, it can not only seal the smooth sucker rod, but also seal the oil pipe space when there is no smooth sucker rod. In order to achieve the purpose of safe production and protection of the surrounding environment.
Tubing anchor is a downhole device for anchoring downhole tubing strings in production and measures. It can improve the stress state of the tubing string, reduce the fatigue damage of the tubing string, control the expansion and contraction of the tubing string, reduce leakage, and extend the service life of the tubing string. Fixing the pipe string during the production process of rod pumping can reduce stroke loss and improve pump efficiency; fixing the pipe string during fracturing, acidification and other processes can improve the pressure-bearing capacity of downhole tools and the pipe string. It can also be used as a mechanism designed to play its role on other downhole tools (such as packers).
