API 11AX down Hole Insert RHA Sucker Rod Pump Oilfield Pumping Equipment for Deep Oil WellsAPI 11AX Oilfield Sucker Rod Pump Price The rod pump is connected to sucker rod after being assemblied on the surface then it is pulled down to the well bottom through the tubing. Thus it is convenient for the inspection and workover because they can be pulled up and down through the tubing and suitable for deeper well. The life span of tubing can be prolonged for decreasing the times of the thread of the tubing being turned on and off and the time of the workover. The rod pump can be classified into two types of mechanical seating and cup seating. Also it is divided into three types as RHA (stationary heavy well barrel top anchor rod pump), RHB (stationary heavy well barrel bottom anchor rod pump) and RHT (travelling heavy well barrel bottom anchor rod pump).           Technology     Production Flow Detailed Images   Main parts process and material: Pump barrel: plain carbon steel plating (A1), ordinary carbon steel carbonitriding (B1), ordinary carbon steel carburizing (B2), low alloy steel nitride (B5).

(483 mm) Hg minimum vacuum with no leakage for a minimum of 3 seconds after vacuum source is isolated. Ball shall be randomly rotated in the seat during the test. Other accessories: plain carbon steel, low alloy steel, stainless steel, brass and other materials.     Packaging & Shipping       Company Information

ALVE BALL AND SEAT The valve ball and seat is a important part of the oil field mining pump, its using directly decides the service life of pump.According to the corrosion characteristics of oil, oil Wells can provide different material We provide different material and structure of the valve cage according to different well conditions. For different material of the valve cage, we have different heat treatment process, to ensure the safety of the use and its mechanical properties. We can produce all pump accessories, at the same time, also undertake the processing of other equipment accessories.   Material Technology     Production Flow Unfinished Product of V11 Valve Ball and Seat   Detailed Images Finished Product of V11 Valve Ball and Seat   Valve ball and seat: stainless steel (A1), cobalt chromium (B2), tungsten carbide (C1), nickel and carbon compounds (C2), titanium carbide (C3).

Rod rotator is an anti-partial wear equipment, specially for deflecting well and horizontal well. Rod rotator makes polished rod and sucker rods rotate clockwise, wear will spead evenly around. Reduce partial wear, prolong the service life of packing in stuffing box and the sucker rods’ service life.   Rod rotator is installed on the wirerope hanger. Polished rod clamp is seated on the rod rotator’s head cover after it grip the polished rod. When pumping unit run to the lower stroke position, the wire rope between the rod rotator and the horse head will pull the drive rod, turn it at a certain angle, Drive handle is lifted up Drive the ratchet to rotate Drive the worm to rotate Worm drive worm gear to rotate Further,drive polished rod and sucker rod to rotate    

A pumping unit gearbox is a vital and critical component of the beam pumping unit. The gear box is specifically engineered to convert the rotary motion of the prime mover, such as an electric motor or internal combustion engine, into the reciprocating motion required by the pump jack. So the gearbox plays a vital role in transmitting power and managing the motion of the pumpjack.   Gear box is consist of the parts as follows,   1. Input shaft 2. Bull gear 3. Pinion shaft 4. Crank arms 5. Bearings and seals   Puyang Zhongshi Group is the API 11E certified manufacturer for pumping units, and supply the gear box.
