Sucker Rod Pump

1.RWB API insert pumps are suitable for many conditions such as low-sand wells and low-level wells, and API certification guarantees reliable quality.​ 2. RWB API insert pumps is designed with a high flow rate and a large inner diameter pump cylinder, which can increase the daily oil production of a single well.。​ 3. RWB API insert pumps has a fixed bottom + less connection structure, which effectively reduces failure and wear.

1.Large displacement tubing pump has dual working state switching function. Large displacement tubing pump can operate in two different working modes through the switch connector between the upper plunger and the lower plunger. 2.Due to this dual working state, the large displacement tubing pump can still maintain efficient operation under the condition of temperature and viscosity changes. When the wellhead temperature drops and the viscosity increases, the switch connector switches to the "open" position and continues to work efficiently. 3.When the large displacement tubing pump switch connector is in the "off" position, the displacement of the pump is the same as the size of the upper pump. When the large displacement tubing pump connector is switched to the "on" position, the displacement matches the oil inlet return pump, reducing energy loss.

1. Chrome brass barrel for oil pump adopts double anti-corrosion structure of brass base and hard chrome plating, which is resistant to strong acid, strong alkali and seawater corrosion. The service life of chrome brass barrel for oil pump is more than 2 times that of ordinary stainless steel barrels for sucker rod pumps. 2. Chrome brass barrel for oil pump is hygienic and safe, perfectly matches the plunger, and effectively prevents medium leakage. 3. Chrome brass barrel for oil pump has passed ISO9001 and API11AX certification, and the whole process from raw materials to finished products is tested. The performance of each chrome brass barrel for oil pump is stable and reliable.

1. The surface of our sand scraping sucker rod well pump plunger is coated with high hardness and wear-resistant alloy (such as nickel-based alloy, tungsten carbide coating), and the inner wall of sand scraping sucker rod well pump is precisely polished to improve the hardness and smooth the surface, further reducing the adhesion and wear of sand particles. 2. The moving parts (plunger and pump barrel) of sand scraping sucker rod well pump are made of highly wear-resistant and corrosion-resistant materials, such as special alloy steel and stainless steel, and the surface of sand scraping sucker rod well pump is treated with high-frequency quenching or chemical plating. 3. In salt water and high H₂S environment, the pump barrel and plunger surface of sand scraping sucker rod well pump are treated with anti-corrosion composite coating, which effectively resists the corrosion of CO₂, H₂S and chloride ions in oil wells.

1.Three-acting tandem oil well pump is suitable for oil wells with sufficient liquid supply. 2.Three-acting tandem oil well pump can suck and discharge liquid during the up and down strokes. Three-acting tandem oil well pump has the characteristics of small pump diameter, large displacement, and deep pumping. 3.The special structure of three-acting tandem oil well pump enables three oil suction and three oil discharge actions to be completed in one reciprocating stroke, which can realize multi-layer oil wells.

1. Elastic seal sucker oil well pump has 45° spiral guide grooves between sealing units, which improves sand discharge efficiency by 60% 2. Elastic seal sucker oil well pump uses all-metal structural parts with special heat treatment (QT800-10 material), which can maintain sealing performance under steam drive (350°C). 3. Elastic seal sucker oil well pump has built-in tungsten carbide guide sleeve (hardness HRA92), which is suitable for horizontal wells with well inclination angle ≤90°.

1. Upward stroke: When the plunger of the heavy oil pump with hydraulic feedback moves upward, the upper liquid enters the lower chamber through a specially designed feedback channel to form hydraulic energy storage. 2. Downward stroke: The stored hydraulic energy is converted into auxiliary thrust (actually measured up to 2-5kN), and the heavy oil pump with hydraulic feedback can effectively overcome the resistance of heavy oil. 3. Pressure balance design: The heavy oil pump with hydraulic feedback uses our original two-way flow channel structure to balance the pressure inside and outside the pump in real time to avoid air lock and sand jam.

1. Our forced valve rod pump adopts mechanical forced valve design, the response speed of the traveling valve is increased by 80%, gas interference is effectively blocked, and the gas lock rate is reduced by 90%. 2. The forced valve rod pump is suitable for heavy oil wells with viscosity >10000 mPa·s, with a theoretical displacement of up to 800m³/d (83mm pump diameter), and an average daily increase of 35%-50%. 3. The stroke range of the forced valve rod pump is 2.0-6.0 meters, and the pump barrel length can be adjusted to 7.5 meters, which can easily cope with ultra-deep well conditions of 2000-5000 meters.

1. Our strong opening and closing sucker oil pump has brought our customers stable operation, increased daily oil production, thousands of yuan in annual electricity bill savings, and reduced pump stoppage and maintenance times through large flow channel design, low-resistance opening and closing structure and precision matching parts. 2. The key components of the strong opening and closing sucker oil pump are made of hard alloy, which is wear-resistant and corrosion-resistant. Combined with reasonable structural design, the frequency of pump body replacement is reduced, which can save labor and production stoppage costs. 3. The strong opening and closing sucker oil pump has an automatic self-aligning function and modular structure, which can be flexibly adapted to vertical wells, inclined wells, deep wells and other well types. It is easy to disassemble and assemble on site without special tools. It is more economical to purchase and faster to maintain, reducing the difficulty and cost of well team operation and maintenance.
