Description
Technical field
The utility model belongs to technical field of oil extraction equipment, is specifically related to a kind of novel oil-filling type bilayer waterproof packing box.
Background technique
Packing is the sealing element on pumping unit, and pumping unit realizes dynamic sealing during oil extraction, by packing and sucker rod, existing
The packing and sucker rod of pumping unit are in dry grinding state, will accelerate the loss of packing, or even the thorn leakage phenomenon of packing occur, increase
Maintenance maintenance cost, reduces oil recovery efficiency.So it is very necessary for designing a kind of novel oil-filling type bilayer waterproof packing box
's.
Summary of the invention
The purpose of the utility model is to provide a kind of novel oil-filling type bilayer waterproof packing boxs, and the packing box is in original packing
On the basis of box structure, lubrication cavity and sealing lubricating oil packing are increased, butter is full of to lubrication cavity, plays lubrication polished rod
Effect solves the problems, such as wet well or producing well polished rod dry grinding packing, and then solves the problems, such as loss packing and thorn leakage.
The technical solution adopted in the utility model are as follows: a kind of novel oil-filling type bilayer waterproof packing box, including former packing box
And sucker rod, it further include outer press cover, internal gland, profit oil cavity, spring, sealing butter packing and gasket；Outer press cover and lower section
Former packing box is threadedly coupled, and the outer press cover top and profit oil cavity welding, profit oil cavity top and another outer press cover screw thread connect
It connects；The spring is mounted on profit oil pocket intracorporal sucker rod, and both ends of the spring is respectively equipped with sealing butter packing, wherein upper end
It seals and is equipped with internal gland above butter packing, be equipped with another internal gland below the sealing butter packing of lower end；The profit oil pocket
Body is equipped with grease nipple.
Further, the both ends of the spring is welded with gasket.
Further, the grease nipple is equipped with sealing cover.
Further, the internal gland is mounted in outer press cover.
Further, the extension bar that can be stretched for screwing outer press cover is installed on the outer press cover.
Further, the profit oil cavity top is equipped with the glass viewing port for observing profit oil.
Further, the insulating layer for heat preservation is equipped with outside the profit oil cavity.
Further, lubrication cavity is installed additional on the former packing box.
The utility model has the beneficial effects that providing a kind of novel oil-filling type bilayer waterproof packing box, the packing box is in original
On the basis of having packing box structure, lubrication cavity and sealing lubricating oil packing are increased, butter is full of to lubrication cavity, plays profit
Sliding polished rod effect solves the problems, such as wet well or producing well polished rod dry grinding packing, and then solves loss packing and thorn leakage
The problem of.The packing box is improvement and installation on the basis of original packing box, improves installation effectiveness, and structure is simple, and design is closed
Reason, it is securely and reliably, low in cost, it is economic and practical.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of embodiment one.
Specific embodiment:
Embodiment one
A kind of novel oil-filling type bilayer waterproof packing box, including former packing box 9 and sucker rod 1, further include outer press cover 2, interior
Gland 5, profit oil cavity 4, spring 7, sealing butter packing 6 and gasket 8；Outer press cover 2 is threadedly coupled with the former packing box 9 of lower section,
2 top of outer press cover and profit oil cavity 4 weld, and profit 4 top of oil cavity is threadedly coupled with another outer press cover 2；The spring 7 is pacified
On profit 4 sucker rod 1 of oil cavity, 7 both ends of spring are respectively equipped with sealing butter packing 6, wherein the sealing butter packing 6 of upper end
Top is equipped with internal gland 5, is equipped with another internal gland 5 below the sealing butter packing 6 of lower end；The profit oil cavity 4 is equipped with
Grease nipple 3；7 both ends of spring are welded with gasket；The grease nipple 3 is equipped with sealing cover；The internal gland 5 is mounted on external pressure
In lid 2；The extension bar that can be stretched for screwing outer press cover 2 is installed on the outer press cover 2；4 top of profit oil cavity
Equipped with the glass viewing port for observing profit oil, moisten the insulating layer being equipped with outside oil cavity 4 for heat preservation.
On the basis of original packing box structure, lubrication cavity and cavity inner assembly internal gland, sealing butter dish are increased
The spring of root and both ends welding flat shim, is threadedly connected to original packing box top.In use, being first turned on top
The outer press cover of threaded connection will seal butter packing and take out with gasket spring, fills it up with conventional seals packing in lubricating cavity body, will
Outer press cover installation is in situ.Start pumping unit to operate normally, at this point, packing is dry grinded with polished rod, polished rod is made to obtain polishing.So
Afterwards, stoppage in transit pumping unit is again turned on upper press cover, takes out common packing, be sequentially added into sealing butter packing root two, be welded with it is flat
Spring, the sealing butter packing root two of gasket, install original position for outer press cover, inject butter to grease nipple using grease gun, make
It lubricates cavity and is full of butter, play the role of lubricating polished rod, starting pumping unit operates normally, and solves wet well or producing well polished rod
Dry grinding packing, and packing is lost and pierces the problem of leaking.
