Sucker rod pump is equipped with a support joint (there are two support joints in API-RHBM-AC), attached to the tubing string, which will down to the bottom of the well with the tubing string. Plunger assembly connected to rod string and together with the pump overall down to joint position, then the pump is fixed inside the joint. Plunger assembly with the sucker rod string up and down reciprocating movement to achieve pumping work.When it breaks down, no need to lift the tubing string out, just put the whole pump out of the well through the rod string.
Description
(1) API-TH(B)M, mechanical support at the bottom, thick barrel wall;
(2) API-TH(B)C, leather cup support at the bottom, thick barrel wall;
(3) The tubing pump barrel assembly is directly connected and fixed to the tubing string and goes down to the bottom of the well. The plunger assembly is connected to the sucker rod and down into the bottom barrel position, and reciprocates up and down with it, so as to realize the oil recovery process
(4) In the process of oil production, when there is a problem between the moving valve pair and the fixed valve pair, the valve pair can be lifted out with the extractor through sucker rod and plunger instead of pulling the whole pumping combination and tubing string out of the well, which reduces the labor and cost of the operation.
Suitable for conventional oil pumping and large displacement oil extraction, small pump depth-pumping and heavy oil, high pour-point oil, injection well, cluster deviated well.
Working principle
The motor drives the reducer through the long-life, heavy-duty load belt, and the reducer drives the gear rotating, the gear drives the long annular rack to move up and down. When the rack moves to the point of top or bottom, the gear makes level motion to realize reversing. The rack links the belt makes up and down reciprocating motion, which makes the sucker rod up and down to draw oil.
Advantages and Features
1. High efficiency. Gear-rack device makes the drive chain of entire transmission system short result in saving energy more than 25% compared with beam pumping unit.
2. Long stroke increased efficiency of pump and entire system.
3. The system runs smooth and reliable.
4. Simple structure, easy operation and low cost of maintenance
5. Superload long stroke pumping units can be customized according to customersâ?? requirements.
Scope of application:
Submersible electronic pump is mainly used in sucking water and oil from the well, and a very important equipment in mechanic oil extraction. It is applicable to hot spring mining from geothermal well, well salt mining and coalbed methane mining.
Description
APIC series pumping unit is a conventional beam pumping unit, balanced with crank, a ground power plant which is common and wide-used in rod production. It complies with API Spec 11E and other related standards and obtained PI license logo.
Performance features
1. Module by module design through virtual manufacturing technology, which optimizes its structure, making the components more standard, universal and serial.
2. Key parts are developed by finite element analysis, assuring its reliability and stability.
3. The reducer adopts transmission of symmetrical shunt involute or double arc herringbone gear, giving a good seal, low noise, excellent stability reliability and durability.
4. Easy to operate, maintain and long-life.
Structural features:
Dual-horse head pumping unit is an energy-saving products with long stroke length and low stroke frequency, for the production of low or medium viscosity crude oil and high water-cut oil.
Sucker rod is an important part of sucker rod pumping equipment. In the process of oil production, sucker rod is used to transfer energy and the ground power or movement to the underground pump.
