Embodiment Construction

[0026] 1. Production process steps:

[0027] 1. Braided rope:

[0028] First, 8-16 strands of high-molecular polyethylene rope are braided to form a high-molecular polyethylene rope core, and then 32-48 strands of polyester fiber rope are wrapped around the rope core to obtain continuous polyester fiber rope wrapped around the rope core. rope.

[0029] 2. Obtain the rope body:

[0030] According to the use requirements of the pumping unit, cut a section of rope body with a length of 9.3m from the continuous rope.

[0031] 3. Make a ring buckle at both ends of the rope body. The manufacturing process of each ring buckle is:

[0032] On the rope body, at 120cm from the end, carry out the first section of anti-loose binding with polyester fiber string, and the length of the binding section is 5cm.

[0033] Strip the polyester fiber rope outside the core rope with a length of 45cm at the end of the rope body, and cut off the stripped polyester fiber rope evenly, exposing the f...

Abstract

The invention relates to the technical field of cable production and pumping units and relates to a high-molecular ring-fastener horse head driving cable for pumping units and a production method thereof. A cable body is made by braiding polyester fiber cords around a high-molecular polyethylene core; ring fasteners are formed at the two ends of the cable body respectively; the joints of the cablebody with the ring fasteners are wrapped in high-molecular fibers to form covering layers. The production method is simple and reasonable; the whole material is a high-molecular material; the high-molecular ring-fastener horse head driving cable for pumping units has good wear resistance, acid resistance, alkali resistance, weatherability and aging resistance, is applicable to various severe environments, has service life generally of 5-6 years and longer, is free of maintenance each year so that idling chances are decreased greatly, and the costs, such as manpower cost, caused by frequent maintenance are avoided.

Description

technical field [0001] The invention relates to the technical field of rope production, and also relates to the technical field of the oil pumping device of the pumping unit. Background technique [0002] The donkey head driving rope braid is the key part of the pumping unit, the middle ring is set on the output end of the donkey head driving device, and the ring heads at both ends of the donkey head driving rope braid extend out of the pressure plate of the rope hanger, and then extend out of the pressure plate Insert pins between the two ring heads and the connecting heads of the sucker rods, and connect nuts at both ends of the pins, so as to connect the donkey head driving rope braids with the sucker rod, and realize the sucker rod through the donkey head driving rope braids. The up and down reciprocating motion in the well is used for pumping oil. [0003] The current donkey head driving rope braids are all made of steel cables. Since the oil field and mine operations ...
