Problems solved by technology

Represents the development direction of the polished rod sealer. Some of the polished rod sealers currently in use are welded with a barrel, and the crude oil leaked from the packing gathers in the barrel, and it takes time and effort to clean it. In summer, the rainwater fills the barrel, and the dirty oil flows out and becomes a source of pollution. , this kind of barrel does not solve the pollution caused by the leakage of crude oil from the packing to the Christmas tree and the well site
