Abstract
The utility model relates to a composite sealing feeding loop that can lubricate and seal automatically, being a component on a sealing device; the utility model has a guide ring whose both sides are provided with composite feeding loops, a plurality of guide holes are radially on the guide ring, the outer circle and the inner circle are respectively provided with a groove, the utility model can be applied on sealing structures such as feed rod sealer and stuffing box to coordinate with sealant feeding components arranged on the sealing structures to lubricate the frictional place and to compensate the abrasion in operation so as to improve the sealing effect and prolong working life, the nicer lubricity of the utility model can reduce the operational load of oil extractor to function as energy saving and prolonging the working life of oil extractor, the utility model can be applied not only on sealing the feed rod of an oil extractor, but also axle form components.
Description
Technical field
The utility model provides the parts on a kind of seal arrangement.
Background technique
At present, on the seal arrangement (as polished rod sealer, stuffing box) of oil field oil recovery with the polished rod on the pumping unit or other shaft-type part spare, the filler of employing is rubber packing or graphite packing.These fillers only have seal action, unlubricated effect, and wearing and tearing easily in the using process, working life is short, the oil accident that causes because of the packing wearing and tearing often occurs.After the wearing and tearing, behind shutdown of pumping machine, could change, complex operation, the shutdown of pumping machine time is long, and the maintenance cost height has reduced the continuous operation time of pumping unit.Higher because of the crude oil sand content, dead time is long slightly even can cause oil well pump " sand card " problem, has a strong impact on the ordinary production in oil field.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of combined type self oiling, automatic stuffing box packing ring, to improve the sealing effect and the working life of seal arrangement.
The utility model is achieved in that combined type self oiling, automatic stuffing box packing ring, and it has guide ring, and the guide ring both sides have the combined stuffing ring body respectively, are radially distributed with a plurality of material guide holes above the guide ring, and is fluted respectively on the cylindrical of guide ring and the interior circle.
Adopt the combined type self oiling of said structure, automatic stuffing box packing ring, can be used on the seal arrangements such as polished rod sealer, stuffing box, cooperate with the lubrication and seal agent feed pieces such as grease nipple that are provided with on the seal arrangement, the friction position is lubricated, the wearing and tearing that produce in the using process are compensated, thereby improved sealing effect and working life.Because lubricity is good, can reduce the operating load of pumping unit, play certain energy-conservation and prolongation pumping unit effect in working life.Except that the sealing that can be used for oil-extractor polish-rod, also can be used for the sealing of other shaft-type part spare.
Description of drawings
Fig. 1 is the schematic representation after the utility model is installed in the seal arrangement.
Fig. 2 has represented the inserting mode of each parts in the utility model.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and working principle.
As shown in drawings, the combined type self oiling of the utility model, automatic stuffing box packing ring, it has guide ring (3), and the guide ring both sides have combined stuffing ring body (1) respectively, be radially distributed with a plurality of material guide holes (4) above the guide ring, fluted respectively on the cylindrical of guide ring and the interior circle.
Described combined stuffing ring body (1) is made up of flexible graphite packing ring (1-1), polytetrafluoroethylene packing ring (1-2), high strength graphite mixed fillers ring (1-3) in guide ring (3) both sides symmetric arrays successively.Flexible stone mill packing ring quality is softer, and lubricity is good, and the powder that comes off in the using process can be along with the lubricated polytetrafluoroethylene packing ring of moving of polished rod.Polytetrafluoroethylene packing ring sealing, wear resistance, supporting effect are better.High strength graphite mixed fillers ring intensity height, wear resistance are good, have supporting effect and certain lubrication.Adopt the combined stuffing ring body can fully utilize the advantage of each packing ring.
As shown in Figure 2, described guide ring (3), flexible graphite packing ring (1-1), polytetrafluoroethylene packing ring (1-2), high strength graphite mixed fillers ring (1-3) are that two semi-ring bodies of zigzag face are pegged graft and constituted by plug surface respectively.This inserting mode is similar to the dovetail groove inserting mode.Adopt this inserting mode, the installation and removal of each ring are all more convenient.Certainly, also can adopt other inserting mode easily.
During use, the utility model is installed in the shell (5) of seal arrangement, and the shaft-type part spares such as (7) of the polished rod on the pumping unit is positioned in the middle of the seal arrangement.Also gland (6) is installed on the seal arrangement by screw thread.Have the hole with corresponding position, guide ring position on the shell, by screw thread grease nipple (2) as lubrication and seal agent feed pieces is installed on the hole.By grease nipple, can in seal arrangement, inject the lubrication and seal agent.The lubrication and seal agent of injecting enters between polished rod (7) outer surface and each the packing ring internal surface through the material guide hole on the guide ring, focuses bar and all packing rings automatically and is lubricated, and reduces the friction between them.Sealing material in the lubrication and seal agent in time compensates the wearing part of each packing ring, makes seal arrangement remain sealing and lubricated works fine state, thereby prolongs the working life of sealed member greatly.Groove on guide ring cylindrical and the interior circle can play the effect that stores the lubrication and seal agent.
The lubrication and seal agent can be mixed and made into by the sealing material of oiling agent and powdery.
Claims (3)
1, combined type self oiling, automatic stuffing box packing ring, it is characterized in that it has guide ring (3), the guide ring both sides have combined stuffing ring body (1) respectively, be radially distributed with a plurality of material guide holes (4) above the guide ring, fluted respectively on the cylindrical of guide ring and the interior circle.
2, combined type self oiling as claimed in claim 1, automatic stuffing box packing ring, it is characterized in that described combined stuffing ring body (1) is made up of flexible graphite packing ring (1-1), polytetrafluoroethylene packing ring (1-2), high strength graphite mixed fillers ring (1-3) in guide ring (3) both sides symmetric arrays successively.
3, combined type self oiling as claimed in claim 1 or 2, automatic stuffing box packing ring, it is characterized in that described guide ring (3), flexible graphite packing ring (1-1), polytetrafluoroethylene packing ring (1-2), high strength graphite mixed fillers ring (1-3) are respectively two semi-ring bodies grafting formations of zigzag face by plug surface (8).
