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.   

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.

A gate valve is a linear, on/off valve designed to fully open or close the flow of fluid through a pipeline, offering minimal obstruction when open and tight sealing when closed.   Design and Operation Structure: Gate valves typically consist of three main components: the body, bonnet, and trim. The gate itself can be either a solid wedge or a flexible design, depending on the application. Operation: The valve is operated by turning a handwheel or lever, which raises or lowers the gate into or out of the fluid flow. This mechanism allows for a full bore opening, which is equal to the pipe diameter, ensuring maximum flow capacity.   API 6A gate valve is applied in oil and gas, which is for solating sections of pipelines.
