Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil production engineering, and particularly relates to a low-temperature-resistant wear-resistant waterproof packing. BACKGROUND

[0002] In the production process of a pumping unit well, a pumping unit well polished rod seal packing, hereinafter referred to as a packing, needs to be replaced regularly. Common packings include neoprene rubber packing pads, old belts, spiral integrated packings and new spiral integrated packings. In winter production, the outdoor temperature is low, and ordinary old belt packings and neoprene rubber packings will harden, making it difficult to add. After adding, the elasticity is small, which leads to an increase in the operation time, increases the safety hazard, and reduces the production efficiency. In addition, the small elasticity and the increased hardness of the packing reduce the sealing performance of the packing, cause oil and water leakage, and increase the environmental pollution hazard. SUMMARY

[0003] The purpose of the present application is to solve the problems described in the background.

[0004] Technical scheme: The low-temperature-resistant wear-resistant waterproof packing comprises a packing body, and the two ends of the packing body are in a spring-like shape.

[0005] Further, the diameter of the packing body is 16 mm.

[0006] Further, the length of the packing body is 1000 mm.

[0007] Further, the overall material of the packing body is a new composite material formed by mixing polypropylene fiber and polytetrafluoroethylene.

[0008] Further, the packing body does not deform in a low-temperature environment of minus 30 degrees Celsius in winter.

[0009] Beneficial effects: The packing body in the present application adopts a new composite material formed by mixing polypropylene fiber and polytetrafluoroethylene, and the hardness of the packing body is lower than that of the traditional neoprene rubber packing. In the installation and addition process, time and labor are saved. At the same time, the packing body is designed in a spiral shape similar to a spring, which can effectively avoid the invalid winding between the packing and the polished rod during addition, significantly reduce the operation time loss, greatly improve the use convenience, and the packing processing and manufacturing process is simple, and the required raw materials are easy to obtain. Not only reduces the production cost, but also has the advantages of low price. Without complex equipment, batch production can be realized, and it is easy to be rapidly popularized and applied in the related field; The packing of this invention is integrally molded from composite materials, possessing excellent integrity. It will not produce debris shedding during long-term use, ensuring a clean working environment and avoiding potential impacts of debris on equipment operation. At the same time, its special material and structural design endow it with excellent sealing performance, effectively preventing oil and water leaks and reducing pollution to the surrounding soil, water, and other environments, thus meeting environmental protection requirements. Furthermore, this packing can maintain structural stability without deformation in winter environments with temperatures as low as -30 degrees Celsius, demonstrating strong adaptability to harsh working conditions. Its durability far exceeds that of traditional packing, with a stable service life of up to 60 days after a single replacement, significantly extending the replacement interval and reducing maintenance frequency and costs. The packing in this invention is a composite material of polypropylene fiber and polytetrafluoroethylene. Polytetrafluoroethylene itself has excellent lubrication properties, which allows the packing to form good lubrication contact with the polished rod during use, significantly reducing the frictional resistance between the two. This not only effectively protects the polished rod and the packing itself and extends the service life of equipment parts, but also further reduces the operating load of the pumping unit during the up and down strokes, reduces the current consumption of the pumping unit during operation, achieves energy-saving operation of the equipment, and improves the overall operating efficiency and economic benefits.

[0012] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] Example like Figs. 1-2 As shown, a low-temperature resistant, wear-resistant, and waterproof packing is provided, including a packing body 1, the two ends of which are generally shaped like springs; The diameter of the basal body 1 is 16mm, and the length of the basal body 1 is 1000mm; The entire material of the substrate 1 is a new composite material made of polypropylene fiber and polytetrafluoroethylene; The substrate 1 can remain undeformed even at temperatures as low as -30 degrees Celsius in winter; This low-temperature resistant, wear-resistant, and waterproof packing has a rope-like structure with a length of 1000mm and a diameter of 16mm. Its overall design mimics a spring spiral. The body is made of a new composite material made of polypropylene fiber and polytetrafluoroethylene. It not only maintains structural stability and does not deform in winter environments with temperatures as low as -30 degrees Celsius, but also possesses multiple superior properties: Its hardness is significantly lower than traditional nitrile rubber packing, making installation and addition time-saving and labor-saving. The spring-like spiral structure effectively prevents ineffective winding between the packing and the polished rod during addition, greatly reducing operation time and offering excellent ease of use. It also boasts excellent integrity, preventing debris shedding during long-term use and ensuring a clean working environment. Its superior sealing performance effectively curbs oil and water leaks, reducing pollution to the surrounding environment. Its durability far surpasses traditional packing, with a stable service life of up to 60 days after a single replacement, significantly extending replacement intervals and reducing maintenance frequency. Thanks to the composite material properties of polypropylene fiber and polytetrafluoroethylene, this packing possesses excellent lubricity, significantly reducing frictional resistance with the polished rod during use, thereby reducing the operating load of the pumping unit during up and down strokes, lowering the operating current, and improving equipment efficiency. Furthermore, this packing is affordable, easy to promote and popularize, and its simple and convenient manufacturing process effectively reduces overall production and usage costs. The specific manufacturing method is as follows: First, prepare the necessary materials and tools, including one 1-meter-long, 16mm-diameter polypropylene fiber rope, 500g of 60% polytetrafluoroethylene emulsion, one hot melt knife, one 100mm flathead screwdriver, and one 600ml empty mineral water bottle with a cap; then, use the preheated hot melt knife to heat melt the two ends of the polypropylene fiber rope to prevent the fibers from fraying; next, cut the 600ml mineral water bottle horizontally from top to form a container about 16.5cm high, which will be used to hold the polypropylene fiber rope and polytetrafluoroethylene emulsion; place the treated polypropylene fiber rope evenly into the container in a spiral shape, and then... Using a 100mm flathead screwdriver, gradually press the rope firmly to ensure it adheres tightly to the inner wall of the container and to the rope itself. Then, slowly pour 60% polytetrafluoroethylene (PTFE) emulsion into the container until the emulsion completely submerges the polypropylene fiber rope, ensuring the rope fully absorbs the emulsion. Use the top of a previously cut mineral water bottle as a lid to tightly seal the container, preventing emulsion evaporation and impurities from entering. After soaking for 24 hours in a sealed container, open the lid, remove the polypropylene fiber rope, and place it in a well-ventilated and dry place to air dry naturally. Pour the remaining 60% PTFE emulsion back into the original storage container and seal it for future reuse. Finally, tidy up the tools used, clean the work area, and complete the entire packing process.
