The sealant hardness and lubricity of oil-extractor polish-rod, wear-resistant sealing internal layer have good wear-resisting new energy, improve packing ontology
Abrasion-resistance, elastic force outer layer is elastic layer, due to having elasticity, in use process, squeezes pumping unit light under pressure
The sealant of bar, wear-resistant sealing internal layer and elastic outer layer make the packing ontology have superior wear resistence and leakproofness, to prolong
The service life of long packing ontology, therefore the basic body of frequent carousel is not necessarily in oil recovery process, manual operation load is reduced, effectively
Improve oil recovery efficiency.
Further, Nian Jie elastic outer layer and wear-resistant sealing internal layer are equipped between the elastic outer layer and wear-resistant sealing internal layer
Adhesive layer.
In this way, the intensity that wear-resistant sealing internal layer can fit closely raising packing ontology with elastic outer layer by adhesive layer makes
Packing ontology is more durable.
Further, the base material is rubberized canvas.
In this way, the base of rubberized canvas material has good elasticity and wearability, and then improve the wear-resistant energy of packing ontology
Power.
Further, the wear-resistant oxidant layer is evenly arranged in rubberized canvas layer surface by polytetrafluoroethylene (PTFE) glue.
In this way, antiwear additive is evenly distributed on rubberized canvas layer surface under the action of polytetrafluoroethylene (PTFE) glue, to improve oil pumping
The sealant hardness and lubricity of machine polished rod.
Further, the elastic outer layer coats wear-resistant sealing internal layer surface using polyurethane.
In this way, polyurethane has good elasticity, pumping unit when in use, can extrude under the elastic force effect of elastic outer layer
The sealant of oil-extractor polish-rod, lift-off seal, so as to avoid well head leakage.
Further, the antiwear additive layer material is graphite powder or lead powder.
In this way, graphite powder or lead powder have good lubricity and wearability, the wear-resisting property of packing ontology is improved, is extended
The service life of packing ontology.
The beneficial effects of the utility model are: compound double-layer seal packing provided by the utility model compares common disk
Root is more wear-resistant, and wear-resistant sealing internal layer and elastic outer layer make packing ontology have superior wear resistence and leakproofness, to extend
The service life of packing ontology is not necessarily to the basic body of frequent carousel in oil recovery process, reduces labor intensity of operating staff, mention
High oil recovery efficiency decreases environmental pollution, the utility model structure is simply closed simultaneously because having good leakproofness
Reason, is widely portable in oil extraction system.
