Abstract
For an oil field machinery oil technology oil pumping well head polished rod sealer servicing unit, comprising: secondary seal device, lubricating cylinder, pressure cap, Glan, sealed packing, butter injection hole, sewage draining valve, polished rod mouth.Owing to having set up primary seal and increased lubricating polished rod on former oil pumping well head polished rod sealer, wellhead sealing effect is increased, extend the application life of well head sealing packing, reduced site operation personnel's labour intensity, improved work efficiency and management level.Be applicable to the on-the-spot use in production line, there is higher economic benefit and social benefit.
Description
Technical field
The utility model relates in the beam pumping unit wellhead polish rod seal process of oil field and the technology of design, specifically a kind of polish rod sealer for pumping unit well servicing unit.
Background technology
During beam pumping unit work at present, in order to prevent, be drawn into ground leak of liquid in oil well production process, wellhead polish rod just needs sealing, otherwise will cause environment pollution, production loss.Due to polished rod at work constantly with sealed packing friction, sealed packing is because of constantly loss of friction, needs constant adjustment sealer pressure cap and regulates the elasticity of sealed packing to reach the object of raising sealing effectiveness.But in use procedure, the well liquid physical property due to oil well institute output is different at the scene, such as oil well, see that polished rod and sealed packing that the reasons such as polymer, height is moisture, oil is thick, air content is large, feed flow is not enough cause are lubricated because lacking, friction aggravation, sealed packing is frequently adjusted, and constantly shorten service time, and well head is often missed oil gas, contaminated environment, change frequently sealed packing and cause oil well production time decreased, cost of materials increases, and labor intensity of operating staff increases.
Summary of the invention
The purpose of this utility model is exactly the deficiency for the technical existence of polished rod sealer of scene use, has designed a kind of oil-well optical rod sealing apparatus servicing unit.
Above-mentioned purpose is realized by following technical proposals:
The utility model comprises: secondary seal device, lubricating cylinder, pressure cap, Glan, sealed packing, butter injection hole, sewage draining valve, polished rod mouth; Its polish rod sealer for pumping unit well servicing unit lubricating cylinder is welded on the top of polished rod sealer, polished rod mouth and polished rod sealer polished rod mouth center-aligned, by screw thread and secondary seal device, link together, on polished rod, putting sealed packing (packs in secondary seal device, install Glan and pressure cap, by adjusting the fit clearance between pressure cap and Glan, adjust the elasticity of sealed packing; During use, according to hole condition, from butter injection hole, to lubricating cylinder, inject butter, lubricated polished rod, misses when serious and goes out to connect blow-down pipe at sewage draining valve when polished rod position, and sump oil is imported in pollutant discharge tube.
The beneficial effects of the utility model are: polish rod sealer for pumping unit well servicing unit is owing to having increased the lubricated of polished rod, extended the application life of sealed packing, increased secondary seal device simultaneously, improved sealing effectiveness, not only reduced and stopped the well time, reduced again worker's labour intensity, improved work efficiency and management level, be applicable to beam pumping unit, conveyor polished rod seal, there is higher economic benefit and social benefit.
Accompanying drawing explanation
The main TV structure schematic diagram of Fig. 1-the utility model.
In accompanying drawing, 1. secondary seal device, 2. lubricating cylinder, 3. pressure cap, 4. Glan, 5. sealed packing, 6. butter injection hole, 7. sewage draining valve, 8. polished rod mouth.
The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
Polish rod sealer for pumping unit well servicing unit, is mainly comprised of secondary seal device 1, lubricating cylinder 2, pressure cap 3, Glan 4, sealed packing 5, butter injection hole 6, sewage draining valve 7, polished rod mouth 8.Its polish rod sealer for pumping unit well servicing unit lubricating cylinder 2 is welded on the top of polished rod sealer, polished rod mouth 8 and polished rod sealer polished rod mouth center-aligned, by screw thread and secondary seal device 1, link together, on polished rod, putting sealed packing 5 packs in secondary seal device 1, install Glan 4 and pressure cap 3, by adjusting the fit clearance between pressure cap 3 and Glan 4, adjust the elasticity of sealed packing 5; During use, according to hole condition, from 6 butter injection holes, to 2 lubricating cylinder, inject butter, lubricated polished rod, misses when serious and goes out to connect blow-down pipe at 7 sewage draining valves when polished rod position, and sump oil is imported in pollutant discharge tube, reduces environment pollution.
