Description
Technical field:The utility model relates to the servicing unit that oilfield is produced, especially a kind of new type of rod sealing unit.
Background technology:In the oil field development manufacturing process, the heavy oil wells of oil well, go out the phenomenon that the Polish rod packing leakage of oil appears in well, give affecting of daily production work, and cause certain production loss.
The utility model content:
It is high that the purpose of this utility model provides service efficiency, a kind of new type of rod sealing unit that life-span is long, it has solved the problem in the present technology, the purpose of this utility model is to realize like this, it is by the polished rod sealer main body, one-level packing_seal chamber, the packing gland, clamping cap, secondary packing base, the secondary seal chamber, secondary packing gland, secondary packing clamping cap is formed by connecting, the utility model is by the polished rod sealer main body, one-level packing_seal chamber, the packing gland, clamping cap, secondary packing base, the secondary seal chamber, secondary packing gland, secondary packing clamping cap is formed by connecting, one-level packing_seal chamber is arranged in the polished rod sealer main body, the one-level packing_seal is equipped with packing in the chamber, be pressed with the packing gland at packing, the clamping cap that is threaded is arranged at the packing gland.
Secondary packing base is arranged in the clamping cap top, the secondary seal chamber is positioned on the secondary packing base, and be connected on the external screw thread in one-level packing_seal chamber, secondary seal is equipped with packing in the chamber, packing in the secondary seal chamber is pressed with secondary packing gland, at secondary packing gland secondary packing clamping cap is arranged, and by being threaded.
During use, packing is added in the primary seal chamber first, press the packing gland, in the butter chamber, fill it up with butter, after tightening with pressure-pad, put secondary packing base, with tightening above the secondary seal chamber installation primary seal body, with adding packing in the secondary packing chamber, tighten pressure-pad, adjust the packing elasticity, tighten up and down lock bolt with interior hexagonal wrench.
Meaning of the present utility model: 1, change two-stage sealing into by the sealing of traditional single-stage, prolonged packing application life, the direct secondary packing that adds with pressure when add packing next time has omitted anti-pressure program, has shortened and has stopped the well time; 2, be equipped with in the centre
The butter chamber, can effectively reduce the polished rod friction heating, go out well, the short problem of heavy oil wells packing period of validity between having solved.
