Abstract
The utility model relates to an automatic compensation granule mixes lubricated formula packing box of packing. The problems that an O-shaped packing is poor in wear resistance, low in compensation performance and short in effective sealing time in the prior art are mainly solved. The method is characterized in that: the sucker rod (7) is sleeved with a pressure spring (2), a gland (1) and a spring lower baffle plate (6) are arranged above and below the pressure spring (2), the gland (1) is in threaded connection with the shell (9), and an oil storage chamber (4) is arranged between the gland (1) and the spring lower baffle plate (6); granular packing (8) is arranged between the lower spring baffle sheet (6) and the lower granular material baffle sheet (10), the lower granular material baffle sheet (10) is arranged on the upper part of the wellhead connecting piece (11), and the lower end of the shell (9) is tightly matched and connected with the wellhead connecting piece (11). The automatic compensation particle mixed packing lubrication type packing box realizes long-term lasting effective sealing, and has the advantages of good wear resistance, lasting lubrication and high sealing efficiency.
Description
Technical field
The utility model relates to a kind of packing box in the petroleum production engineering field, oil field, particularly a kind of automatic compensating particles mixed fillers lubricated type packing box.
Background technology
In the oil recovery field, oil field, rod-pumped well well head packing box uses " O " shape packing to reach sealing purpose for many years all the time, but problem such as this type of packing box ubiquity wears no resistance, compensation performance is low, effectively the sealing time is short.Not only need often to change " O " shape packing, for preventing the packing leakage of oil, the oil recovery workman frequently increases pressure to " O " shape packing, or " O " shape packing is replaced with old belt, if things go on like this, can cause polished rod to damage and accelerate, and energy consumption increases, and polished rod damages to be accelerated,
And the frequent change packing increase to shut down number of times rate when reducing equipment operation, the 4th, and change packing and be prone to potential safety hazard winter.
Summary of the invention
The utility model technical problem to be solved be overcome that use " O " the shape packing that exists in the background technology wears no resistance, compensation performance is low, effective short problem of sealing time; And a kind of automatic compensating particles mixed fillers lubricated type packing box is provided; This automatic compensating particles mixed fillers lubricated type packing box is realized long-term lasting effectively sealing; Abrasion resistance is good, and lubricated lasting, leakage efficiency is high.
The utility model solves its problem and can reach through following technical scheme: this automatic compensating particles mixed fillers lubricated type packing box comprises sucker rod, housing; Be with compression spring on the described sucker rod; The upper and lower gland and the spring lower gear plate of being equipped with of compression spring; Gland is threaded with housing, is accumulator between gland and spring lower gear plate, and accumulator corresponding shell top has oil filler point; Be equipped with the particulate material lower gear plate on the sucker rod of spring lower gear plate bottom, be equipped with granular filler between spring lower gear plate and particulate material lower gear plate, the particulate material lower gear plate places well head connector top, and the housing lower end is connected with well head connector tight fit.
The utility model and above-mentioned background compared with techniques can have following beneficial effect: this automatic compensating particles mixed fillers lubricated type packing box is owing to adopt said structure; Only need the balancing force of initial adjustment compression spring can realize sealing over a long time, reduced the replacing packing operation frequency; The annual filler of only need dosing a time reduces labor intensity of operating staff, increases work efficiency; Graphite in the filler and accumulator oil plant have played lubrication to polished rod, reduce and stablized the coefficient of friction of polished rod and filler, ensure employee's handling safety, and energy-saving effect is obvious, greatly reduces energy consumption of electrical machinery.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure: 1-gland, 2-compression spring, 3-oil filler point, 4-accumulator, 5-pad, 6-spring lower gear plate, 7-sucker rod, 8-granular filler, 9-housing, 10-particulate material lower gear plate, 11-well head connector.
The specific embodiment:
To be described further the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, this automatic compensating particles mixed fillers lubricated type packing box comprises sucker rod 7, housing 9, is with compression spring 2 on the described sucker rod 7; The upper and lower gland 1 and the spring lower gear plate 6 of being equipped with of compression spring 2; Gland 1 is threaded with housing 9, and 6 of gland 1 and spring lower gear plates are accumulator 4, and the lubrication oil in the accumulator 3 mainly plays the effect of compression spring corrosion-resistant; And at polished rod surface formation oil film, what additional fillers was required lubricates; Accumulator 4 corresponding shell tops have oil filler point 3, are used to inject lubrication oil; Be equipped with particulate material lower gear plate 10 on the sucker rod of spring lower gear plate 6 bottoms, 10 of spring lower gear plate 6 and particulate material lower gear plates are equipped with granular filler 8, and particulate material lower gear plate 10 places well head connector 11 tops, and housing 9 lower ends are connected with well head connector 11 tight fits; 6 of described compression spring 2 and spring lower gear plates are equipped with pad 5, and effect is to pass to filler to the pressure of spring equably; Described granular filler 8 is the oil resistant rubber particle, gathers tetrafluoro particle and graphite mixture that housing 9 lower ends are connected with well head connector 11 tight fits.
When this automatic compensating particles mixed fillers lubricated type packing box uses; Adjustment gland 1 downward compression pressure spring 2; Through spring lower gear plate 6 pressure is passed to filler; Reached and make filler hold the effect of sealing tightly to polished rod, the compression spring has played the compensating action to granular filler pressure in recovery process.
