Abstract
The invention relates to a pumping unit polish rod mechanical sealing device which comprises a packing box and packing. The packing box is filled with the packing. An adjusting spring large pressing cover, an adjusting spring, an adjusting spring outer sleeve and a packing small pressing cover are further included. The adjusting spring is arranged in the adjusting spring outer sleeve. The bottom of the adjusting spring is integrally connected with the packing box. The adjusting spring large pressing cover is arranged at the top of the adjusting spring outer sleeve. The packing small pressing cover is arranged between the bottom of the adjusting spring and the packing. The spring is used for adjusting the tightness of the packing, automatic adjusting can be carried out at any time according to tightness frequency changing of the packing in a sealing box, manual operation is avoided, time and labor are saved, in addition, the service life of the packing is prolonged, and a large amount of cost is saved for oil field production.
Description
Technical field
The invention belongs to OFME field, relate to a kind of oil-extractor polish-rod mechanically-sealing apparatus.
Background technology
The filler elasticity adjustment of current sealing oil-extractor polish-rod is carried out with the large gland of artificial rotating disk root box, the technical limitation existed is: in polished rod pumps, the elasticity of packing filling has several change frequency, the instantaneous variation of elasticity cannot be adapted to complete adjustment by hand, easily cause oil plant to leak.Therefore, invent a kind of mechanical device that can complete adjustment according to the instantaneous variation of packing filling elasticity and seem particularly important.
Summary of the invention
The object of this invention is to provide a kind of oil-extractor polish-rod mechanically-sealing apparatus, overcome and use the large gland of artificial rotating disk root box to adjust filler elasticity at present, adjustment cannot be completed according to the instantaneous variation of packing filling elasticity, easily cause the problem that oil plant leaks.
The present invention is achieved through the following technical solutions: oil-extractor polish-rod mechanically-sealing apparatus, comprises packing box and packing filling, the in-built full packing filling of packing box; Also comprise the large gland of regulating spring, regulating spring, regulating spring overcoat and the little gland of packing filling, described regulating spring overcoat is built with regulating spring, regulating spring jacket bottom and packing box connect as one, the large gland of regulating spring is equipped with at regulating spring overcoat top, and packing filling little gland is housed bottom regulating spring and between packing filling.
Further, also comprise the little gland of regulating spring, it is inner that the little gland of regulating spring is sleeved on the large gland of regulating spring, and top is conditioned the large gland of spring and compresses, bottom contact regulating spring.
Further, bottom the little gland of described packing filling, also guide ring is housed, and the bottom surface circumference of guide ring is outward-dipping.
Further, described guide ring inclined bottom surface angle is 30-45 °.
Adopt the good effect of technique scheme: the present invention uses the elasticity of spring to packing filling to regulate, according to several frequency changes of packing filling elasticity in seal box, can automatically adjust at any time, avoid manual operation, time saving and energy saving; In addition, extend the application life of packing filling, for field produces has saved great amount of cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 packing box, 2 packing fillings, the large gland of 3 regulating spring, 4 regulating springs, 5 regulating spring overcoats, the little gland of 6 packing filling, the little gland of 7 regulating spring, 8 guide rings.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described further, but should not be construed as limitation of the present invention:
Fig. 1 is structural representation of the present invention, and as shown in the figure, oil-extractor polish-rod mechanically-sealing apparatus, comprises packing box 1 and packing filling 2, the in-built full packing filling 2 of packing box 1.Also comprise the little gland 6 of the large gland of regulating spring 3, regulating spring 4, regulating spring overcoat 5 and packing filling, described regulating spring overcoat 5 is built with regulating spring 4, connect as one with packing box 1 bottom regulating spring overcoat 5, the large gland 3 of regulating spring is equipped with at regulating spring overcoat 5 top, and packing filling little gland 6 is housed bottom regulating spring 4 and between packing filling 2.Packing filling is pressed down by the little gland of packing filling bottom regulating spring, make packing filling seal polished rod, when polished rod is up or descending, automatically regulated by the elasticity of regulating spring according to packing filling, make packing filling hold polished rod tightly all the time, keep sealing state.
Further, because the large gland of regulating spring is the outside being enclosed within regulating spring overcoat, therefore, the limited dimension of downward Compress Spring, in order to increase the adjustment yardstick of regulating spring, also comprise the little gland 7 of regulating spring, it is inner that the little gland of regulating spring 7 is sleeved on the large gland 3 of regulating spring, top is conditioned the large gland 3 of spring and compresses, bottom contact regulating spring 4.The little gland of regulating spring is positioned at regulating spring jacket internal, and the little gland of the first compression adjustment spring of the large gland of regulating spring, and then compression adjustment spring, the length of the little gland of regulating spring can also be determined according to different springs.
When the little gland of packing filling presses down packing filling, packing filling has the trend outwards expanded, and in order to enable packing filling better be sealed by polished rod, bottom the little gland 6 of described packing filling, guide ring 8 is also housed, and the bottom surface circumference of guide ring 8 is outward-dipping.Being arranged so that of inclined plane, under the effect of guide ring, makes the trend of the oriented polished rod motion of packing filling, keeps polished rod seal.Further, described guide ring 8 inclined bottom surface angle is 30-45 °, and this angle is too large or too little all improper, all cannot play and order about the effect of packing filling to polished rod motion.
When oil-extractor polish-rod is up, drive packing filling in packing box to move up, Compress Spring, slows down packing filling excessive deformation pressure, and reduce packing filling frictional resistance, packing box top seal is good; Now, bottom packing box, packing filling tightness relaxes, and well liquid enters packing box middle and lower part.On the contrary, packing box top packing filling deflection shrinks, and under pressure effect stretched by regulating spring, contraction speed slows down, and polished rod keeps sealing.Meanwhile, the liquid entering packing box middle and lower part has the effect of lubrication polished rod.When polished rod has diameter difference on the surface of upper and lower stroke, or when there is a depression local, regulating spring automatic compensation packing filler rock deformation pressure, thus the airtight quality keeping packing filling, achieve the function of packing automatic tightness regulating degree.
The present invention uses the elasticity of spring to packing filling to regulate, and according to several frequency changes of packing filling elasticity in seal box, can automatically adjust at any time, avoid manual operation, time saving and energy saving; In addition, extend the application life of packing filling, for field produces has saved great amount of cost.Carry out now 1500 mouthfuls of rod-pumped well tests, without the need to the elasticity of manual adjustment packing, extended packing life cycle 3 times, can also personnel labor intensity be alleviated, reduce environment pollution.
