[0002] In the field of oil extraction, the polished rod sealer is a key device to ensure the sealing of the pumping unit wellhead. Its function is to prevent the leakage of well fluids and gases, ensuring the safety and efficiency of oil production operations. The traditional polished rod sealer has achieved certain results in sealing performance and can meet the basic wellhead sealing requirements; its performance directly affects production efficiency, energy consumption, and safety in production. Among them, during the reciprocating process of the polished rod, a large amount of oil stains and dirt may be generated, and the polished rod sealer needs to be cleaned.
[0003] Due to the fact that the polished rod is easily affected by various external forces during movement, such as vibrations generated during reciprocating operation and impacts of well fluids, oil is easily carried out when the polished rod runs. After long-term accumulation of oil, it is easy to block at the connection between the polished rod and the sealer, corrode the gap, and then reduce the sealing performance of the polished rod, affecting the operation stability and safety. The self-cleaning and protection ability of the polished rod is relatively poor, manual cleaning is rather troublesome, and the disassembly and assembly of common cleaning equipment are not convenient enough, and the usability is not good enough.
