Introduction of RWA insert rod pump：
RWA insert rod pump is a rod-type RWA insert rod pump designed according to API SPEC 11AX (or GB/T18607) standard. According to the support and fixing form of the pump, it can be divided into three categories: moving cylinder type bottom fixed rod type RWA insert rod pump (RWT or RHT), fixed cylinder type bottom fixed rod type RWA insert rod pump (RWB or RHB or RXB), fixed cylinder type top fixed rod type RWA insert rod pump (RWA or RHA).
The model meaning of RWA insert rod pump:
R: Rod type
W: External support
A: Fixed cylinder type, fixed top
Technical parameters of RWA insert rod pump：
RWA insert rod pump barrel length: 8-30 feet, in increments of every 2 feet.(Support customization)
Nominal plunger length: the shortest is 2 feet, and the default is 4 feet when the user does not request it.
Connecting tubing specifications: 2 3/8UPTBG, 2 7/8UPTBG, 3 1/2UPTBG, etc.
Specifications for connecting sucker rods: CYG15.9, CYG16, CYG19, CYG22, etc.
How RWA insert rod pump works：
RWA insert rod pump is equipped with a leather bowl support joint N11, the leather bowl support joint N11 is connected to the tubing column, and the tubing column goes down to the bottom of the well together.The plunger assembly is connected to the sucker rod column and carries the RWA APl insert pump down to the position of the support joint N11 as a whole. The RWA APl insert pump is fixed in the leather bowl support joint N11 by means of external force, and the plunger assembly reciprocates up and down with the sucker rod column to realize the pumping work.
Advantages of RWA APl insert pump：
If there is a quality problem with this kind of RWA APl insert pump, there is no need to raise the oil pipe column. You only need to raise the entire RWA APl insert pump out of the well through the pumping rod column. The operation is simple.
The process and material of the main accessories of RWA APl insert pump：
Pump cylinder: ordinary carbon steel electroplating (A1), low alloy steel nitriding (B5).
Plunger: 1045 steel spraying (B1), 1045 steel spraying (B2), 1045 steel plating (A1), 1045 steel double plating (A2).
Tee: stainless steel (A1), cobalt-chromium-tungsten (B2), tungsten carbide (C1), nickel-carbon compound (C2), titanium carbide (C3).
Other accessories: ordinary carbon steel, low alloy steel, stainless steel, brass and other materials.
FAQ：
Q1: What is RWA APl insert pump?
A: RWA APl insert pump is a kind of high-efficiency oil recovery equipment. It is fixed to the oil pipe column through a leather bowl support joint (N11), and the plunger reciprocates with the oil pumping rod to achieve oil pumping. The structure is simple and reliable.
Q2: What are the main advantages of RWA APl insert pump?
A: This kind of RWA APl insert pump does not need to propose an oil pipe column during maintenance. Only the pumping rod column can be brought out of the whole pump, which greatly simplifies maintenance operations and improves efficiency.
Q3: What is the material of the key accessories of RWA APl insert pump?
A: The pump barrel adopts electroplating or nitriding process (such as carbon steel or low alloy steel), the plunger uses spraying or electroplating 1045 steel, and the ball seat can be selected from stainless steel, cobalt, chromium, tungsten and other hard materials to ensure wear resistance and corrosion resistance.
Q4: Is the maintenance of insert pump for artificial lift complicated?
A: Thanks to the hands-free tube design, this insert pump for artificial lift is easy to maintain, and it can be quickly raised in case of failure. Daily maintenance pays attention to the wear and tear of accessories.
Q5: What scenarios does insert pump for artificial lift apply to?
A: The insert pump for artificial lift is suitable for conventional oil well production, especially for frequent maintenance environments, which can reduce operating costs.
