Abstract
The utility model relates to a lubricating device for preventing dry grinding of a polish rod of a rod pumped well. The lubricating device is arranged at the well root position of a drilling template sleeve and has a cylinder-shaped shell, an outer sleeve and an inner sleeve are disposed in turn in the cylinder-shaped shell, a lubricating oil storage chamber is disposed between the inner wall of the outer sleeve and the outer wall of the inner sleeve, the polish rod penetrates through the inner sleeve, a lubricating filler is disposed between the outer wall of the polish rod and the inner wall of the inner sleeve, and drainage holes enabling the lubricating oil storage chamber to be communicated with the lubricating filler are disposed in the inner sleeve. The lubricating device provided by the utility model is mounted on a packing box at the opening of the rod pumped well, so when the polish rod is heated and dry-ground without oil outlet, the lubricating device lubricates and cools the polish rod through lubricating the lubricating filler between the inner sleeve and the polish rod, thereby effectively preventing oil dropping at the packing box when oil exits from the rod pumped well, prolonging the service life of a wellhead packing of an oil well, and reducing packing adding times of the oil well.
Description
Technical field
The utility model relates to the anti-dry grinding lubricating arrangement of a kind of polished rod of pumping well.
Background technology
In known technical field, along with the exploitation of bridge mouth region piece, stratum energy constantly declines, and between pumpingh well occurs, artificial situation is more frequent.Rod-pumped well is not during fluid, polished rod does not have well liquid lubricated, well head packing and polished rod just there will be dry grinding, at this moment the surface temperature of polished rod is up to more than 100 degree, well head packing is prone to " burning packing " phenomenon, when oil well is fuel-displaced, because well head packing exists in various degree and burns out, pulls tight when not anxious and is prone to well head and runs oily phenomenon, cause environment pollution, production declining, increased the management difficulty of oil recovery work simultaneously.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provide a kind of polished rod of pumping well anti-dry grinding lubricating arrangement.
The utility model solves the technical scheme that its technical problem adopts: the anti-dry grinding lubricating arrangement of a kind of polished rod of pumping well, comprise temporary guide base cover and be arranged on the polished rod in temporary guide base cover, well root position at described temporary guide base cover is provided with lubricating coupler device, described lubricating coupler device has circular cylindrical shell, in described circular cylindrical shell, be provided with successively jacket and inner sleeve, between the inwall of described overcoat and the outer wall of inner sleeve, be provided with lubrication oil storage chamber, described polished rod is through inner sleeve, between the outer wall of described polished rod and the inwall of inner sleeve, be provided with grease packing, in described, put and offer the conduction hole that lubrication oil storage chamber and grease packing are connected.
Further, consider sealing impact mitigation measure, the utility model is equipped with O RunddichtringO upper and lower two of described lubrication oil storage chamber.
Further, consider sealing impact mitigation measure, the utility model is equipped with upper and lower two of described inner sleeve the combined sealing ring that cross section is rectangle, and inwall and the polished rod of described combined sealing ring fit.
Further, as a kind of concrete form of structure, combined sealing ring described in the utility model has the rubber ring that cross section is rectangle, and in the embedding of the inner side of described rubber ring, having cross section is the steel ring of circular arc.
Further, for convenient observation, lubricate oil condition, the utility model is provided with transparent visual window on the outer wall of described circular cylindrical shell.
The beneficial effects of the utility model are: the device in the utility model is arranged on oil pumping machine well head packing box, when polished rod of pumping well generates heat because of not fuel-displaced appearance, dry grinding phenomenon time, the anti-dry grinding lubricating coupler of this polished rod is by the grease packing between lubricated inner sleeve and polished rod, it is immersion oil filler, machine oil in machine oil storehouse in anti-dry grinding lubricating coupler device is lubricated polished rod equably, cooling, frictional force between polished rod and well head packing is reduced, prevent that dry grinding phenomenon from appearring in polished rod and well head packing, when between effectively having prevented, producing well is fuel-displaced from the perverse oil of wellhead packing box, low cost of manufacture, easy for installation, do not affect the daily polished rod load that unloads and adjust the operations such as ginseng, extended the service time of well mouth of oil well packing, reduce the number of times of assembling packings for oil well, rate and oil production while driving a well have been improved, result of use clearly.
