Description
Technical Field
[0001] The utility model relates to the technical field of polished rod sealers, in particular to a spray-proof polished rod sealer which is easy to disassemble and assemble. Background Art
[0002] In oil production operations, the rod sealer is a dynamic sealing device at the wellhead that seals the annular space between the oil pipe and the rod. The rod sealer is generally equipped with upper and lower seals. During normal oil pumping, the upper packing box of the rod sealer plays a role in sealing and preventing blowouts, and the rubber packing can be safely replaced after the lower rubber gate is tightened. The rod sealer is a key device to ensure the wellhead sealing of the pumping unit. Its performance directly affects production efficiency, energy consumption and safe production. When facing complex working conditions, such as high temperature, high wax content, high sand content and other special oil well environments, it has higher requirements for tolerance and damage resistance.
[0003] With the continuous development of oil extraction technology, higher requirements are placed on the performance of rod seals. The sucker rod deviates from the main body of the rod seal during the up and down reciprocating motion, causing eccentric wear of the sealing packing. Its overall calibration and positioning ability is relatively not good enough, and it is easy to produce greater wear after long-term work, affecting its service life. In addition, in the long-term working environment, the long-term operation and wear of the rod can easily affect the sealing effect, causing oil wells to blow out and pollute the environment. The anti-blowout and anti-leakage capabilities are relatively not good enough. For this reason, we propose an anti-blowout rod seal that is easy to disassemble and assemble to solve the above problems. Utility Model Content
