Abstract
A wash pipe packing belongs to drilling equipment packing and is composed of polyester rubberized fabric and a rubber coating. According to the technical features, the polyester rubberized fabric is an annular cylinder, the top and bottom of the cylinder are pressed to prismatic protrusions, and the rubber coating is coated on the outer surface of the polyester rubberized fabric in a pressed mode. Through the technical improvement, the wash pipe packing has the advantages that all gaps between the packing and drilling equipment are effectively filled up through the prismatic protrusions on the upper portion and the lower portion of the polyester rubberized fabric; the rubber coating is high in extensibility, so that seamlessness of the drilling equipment can be guaranteed even when the drilling equipment is moved and extruded; meanwhile, the polyester rubberized fabric is high in wear resistance, so that the frequency for replacing the packing is decreased by 2 to 3 times; the wash pipe packing is durable in use and long in service life, so that the production cost is reduced.
Description
Technical field
The utility model belongs to a kind of drilling equipment filler, is a kind of washing pipe packing specifically.
Background technology
In drilling process, generally use common asbestos cord packing to seal, between packing and washing pipe, there is certain interval, cause sealing effectiveness bad, and wear resistence is poor, application life is short.Also have at present and in gap, think and add gum packing to seal, still, gum packing wears no resistance, and durability degree is low, needs frequent replacing could meet drillng operation, and waste resource, has improved cost of production.
Utility model content
In order to address the above problem, the utility model aims to provide and a kind ofly can solve that existing two kinds of packings wear no resistance and application life of causing is short, and abrasion resistance is good, durable in use, good sealing effect, service time are long, the washing pipe packing of low cost of manufacture.
In order to achieve the above object, the utility model adopts following technical scheme:
Washing pipe packing, is made up of polyester adhesive plaster and rubber coating, and as technical characterictic of the present utility model, polyester adhesive plaster is ring-type cylinder, and cylinder top and bottom is pressed into rib shape projection, and rubber coating is overlaid on polyester adhesive plaster external surface.
As further improvement of the utility model, the cylinder inside wall length of polyester adhesive plaster is less than lateral wall.
The utility model is through above-mentioned technological improvement, reach following beneficial effect: the rib shape projection of polyester adhesive plaster top and the bottom, whole spaces between packing and drilling equipment are effectively filled up, rubber coating ductility is strong, drilling equipment also can be ensured in the time of mobile extruding seamless, simultaneously the abrasion resistance of polyester adhesive plaster is strong, thus the frequency of changing packing reduced 2-3 doubly, durable in use, service time the long cost of production that makes reduce.
Brief description of the drawings
Fig. 1 is washing pipe packing overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Washing pipe packing, is made up of polyester adhesive plaster 1 and rubber coating 2, and described polyester adhesive plaster 1 is ring-type cylinder, and cylinder top and bottom is pressed into rib shape projection 3, and rubber coating 2 is overlaid on polyester adhesive plaster 1 external surface.
The cylinder inside wall length of described polyester adhesive plaster 1 is less than lateral wall.
In quality of rubber materials, added reinforcing agent, accelerator, switch, age resistor, at the temperature of 85 DEG C-100 DEG C, hybrid process is made.
Sheet rubber is made preformed film, then by bonding to film and polyester adhesive plaster, be placed on together on mould and carry out vulcanizing treatment, reaches after cure time, pressure and temperature, and the demoulding obtains washing pipe packing.
The utility model is through above-mentioned technological improvement, reach following beneficial effect: the rib shape projection of polyester adhesive plaster top and the bottom, whole spaces between packing and drilling equipment are effectively filled up, rubber coating ductility is strong, drilling equipment also can be ensured in the time of mobile extruding seamless, simultaneously the abrasion resistance of polyester adhesive plaster is strong, thus the frequency of changing packing reduced 2-3 doubly, durable in use, service time the long cost of production that makes reduce.
