Abstract
The invention relates to a plunger pump packing pressing skeleton and an application method, belonging to the technical field of plunger pumps for oilfields. By using the plunger pump packing pressing skeleton and the application method, a manner of squeezing, deforming and sealing packing by virtue of axial pressure is changed to a manner of pressing the packing directly by using radial pressure to realize sealing; the disadvantages existing in other technologies are overcome; the plunger pump packing pressing skeleton is made of materials such as hard plastic, nylon, copper and aluminum with lower hardness and better plastic deformation; the device is a round pipe, and an outer circle fitting surface, a tapered pressing surface, a buffering groove and a lip are respectively arranged on the round pipe; the taper of the inner surface of the round pipe is 5-50 degrees, the outer bevel angle of the lip is 30-60 degrees, the buffering groove is formed in the bottom of the junction between the lip and the tapered pressing surface, the thickness of the bottom of the buffering groove is 0.5-5mm and the difference between the diameter of the inner hole of the round pipe and the diameter of the outer circle is 10-30mm.
Description
Technical field: the present invention relates to oil field plunger pump technique, especially plunger displacement pump packing compress skeleton and application process.
Background technology: plunger displacement pump is for sealing used various packings at present, mostly adopt braiding to be formed, rely on during use and apply axial compressive force, packing distortion is sealed, such result, easily cause packing loss of elasticity, sealing surface wear to lose efficacy, the term of validity is short, cause changing frequently, artificial, high material consumption.
Summary of the invention: the object of this invention is to provide a kind of structure simple, can ensure that the plunger displacement pump packing of packing long service life compresses skeleton and application process, packing crimp is sealed by dependence axial compressive force, changes into and directly compress packing realization sealing by radial pressure; Which overcome the shortcoming that other technology exists, the object of the present invention is achieved like this,, plastic deformation good material lower by hardness such as rigid plastics, nylon, copper, aluminium is made plunger displacement pump packing and is compressed skeleton, this device is a pipe, pipe is respectively arranged with cylindrical mating surface, compresses the conical surface, buffer memory groove and lip; Pipe inner surface is 5 °--50 ° of taperings, and cone mouth edge thickness is not less than 0.1mm, has seal lip inside at the bottom of inner cone, lip inner bevel is negative 3-15 °, the outer oblique angle of lip is 30-60 °, and bottom lip and compression conical surface junction, have buffer memory groove, buffer memory trench bottom thickness exists
0.5-5mm, the diameter difference of pipe endoporus and cylindrical is 10mm-30mm.
The width strengthening corner angle is 0.1-3mm.
Using method, puts into this device packing and compresses, and make packing shape consistent with this device inner surface configuration, hole size meets job requirement.
Under the pressure ring thrust effect at packing two ends, the radial compacting force sealed working face relying on this device inner conical surface gradient to produce, plays sealing effectiveness, and meanwhile, lip can prevent from overflowing annular seal space during plunger reciprocates.
Meaning of the present invention is: efficiently solve packing and rely on end face to compress deformable seal plunger working face, cause the packing elasticity term of validity shorter, the difficult problem that effective duty cycle is shorter, the Acceptable life of packing extends more than 10 times, substantial saving in maintenance time, significantly save maintenance manpower, material resources.
Accompanying drawing illustrates: Fig. 1 is that plunger displacement pump packing compresses the structural representation of skeleton, in figure 1, cylindrical mating surface 2, compresses the conical surface 3, buffer memory groove 4, lip.
Fig. 2 is buffer memory groove enlarged drawing.
Fig. 3 is the enlarged drawing strengthening corner angle.
Detailed description of the invention: embodiment 1, the present invention are a pipe, pipe is respectively arranged with cylindrical mating surface 1, compresses the conical surface 2, buffer memory groove 3 and lip 4; The outside of pipe is cylindrical mating surface 1; Seal lip 4 is had inside at the bottom of inner cone; Buffer memory groove 3 is had bottom lip 4 and the compression conical surface 2 junction.
Embodiment 2, pipe inner surface are 5 °--50 ° of taperings, cone mouth edge thickness is not less than 0.1mm.
Embodiment 3, lip 4 inner bevel are negative 3-15 °, and the outer oblique angle of lip is 30-60 °.
Embodiment 4. buffer memory trench bottom thickness is 0.5-5mm.
The diameter difference of embodiment 5, pipe endoporus and cylindrical is 10mm-30mm.
The width of embodiment 6, reinforcement corner angle is 0.1-3mm.
Embodiment 7, application process of the present invention, put into this device packing and compress, and make packing shape consistent with this device inner surface configuration, hole size meets job requirement; Under the pressure ring thrust effect at packing two ends, the radial compacting force sealed working face relying on this device inner conical surface gradient to produce, plays sealing effectiveness, and meanwhile, lip seal ring can prevent from overflowing annular seal space during plunger reciprocates.
