Abstract
The utility model provides a wear-resistant packing of a pumping unit, which comprises a packing core (1), wherein the outer surface of the packing core (1) is wrapped with a nylon wire (2); the outer surface of the nylon wire (2) is wrapped with nylon cloth (3); and the packing core (1), the nylon wire (2) and the nylon cloth (3) are vulcanized into a whole body. The packing has the characteristics of resisting wear, heat, oil and aging.
Description
Technical field:
The utility model relates to the used a kind of packing in oil recovery field, an oil field, the wear-resisting packing of especially a kind of oil pumper.
Background technology:
At present, rod pumping system is the main force of oil well production in the oil field, and wellhead polish rod sealer is absolutely necessary in rod pumping system, and wherein the structure of packing, performance are one of key factors of decision sealing effectiveness quality.Enter the middle and later periods owing to recover the oil, the high oil content of extraction liquid moisture content is low, and extraction liquid to the lubricant effect of polished rod worse and worse; the frictional resistance of the product of polished rod and packing is increasing, and existing packing material is single, and is not wear-resisting; application life is very short; need the frequent packing of changing, frequent shutdown is changed packing on the one hand, has both increased cost of production; reduce production efficiency; influence oil well output, bring certain hidden danger to safety work again, easily cause well head to reveal on the other hand environment is caused to a certain degree pollution.
The utility model content:
In order to overcome deficiency of the prior art, the utility model provides a kind of oil pumper wear-resisting packing, and that this packing has is wear-resisting, heat-resisting, oil resistant, ageing-resistant characteristics.
The technical solution of the utility model is: the wear-resisting packing of this oil pumper, comprise the packing core, and the external surface of packing core is coated with nylon wire, and the nylon wire external surface is coated with nylon cloth, and packing core, nylon wire and nylon cloth sulfuration are one.
The material of above-mentioned packing core is a butadiene-styrene rubber; The cross section of packing is circular.
The utlity model has following beneficial effect: owing to take such scheme, there are nylon wire and the two-layer wearing layer of nylon cloth in the outside of packing, wearing layer is stained with lubrication oil, reduced and polished rod between friction factor, make packing more wear-resisting, avoided the well head leakage, prolong the application life of packing, reduced the number of times of oil well replacing packing, reduced cost of production, increase output, avoided environment pollution.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the wear-resisting packing of oil pumper comprises packing core 1, and the external surface of packing core 1 is coated with nylon wire 2, and nylon wire 2 external surfaces are coated with nylon cloth 3, and packing core 1, nylon wire 2 and nylon cloth 3 sulfurations are one.The material of packing core 1 is a butadiene-styrene rubber.The cross section of packing is circular.
During use, oil-extractor polish-rod moves up and down, nylon wire 2 and nylon cloth 3 two-layer wearing layer wearing layers 2 and polished rod friction, and nylon wire 2 and nylon cloth 3 are more wear-resisting than original packing, make packing more wear-resisting; The material of packing core 1 is that butadiene-styrene rubber has better elastic; when polished rod radially wobbles or takes place certain when eccentric; the elasticity of packing core 1 can be replenished it to the gap that polished rod produced, and has avoided the well head leakage, and has alleviated the eccentric wear of polished rod to packing; thereby improve the application life of packing; reduced number of times and the time of oil well, reduced the number of times that oil well is changed packing, reduced cost of production because of the shutdown changing packing and cause; increase output, avoided environment pollution.
Claims (3)
1. wear-resisting packing of oil pumper, comprise packing core (1), it is characterized in that: the external surface of packing core (1) is coated with nylon wire (2), and nylon wire (2) external surface is coated with nylon cloth (3), and packing core (1), nylon wire (2) and nylon cloth (3) sulfuration are one.
2. the wear-resisting packing of oil pumper according to claim 1 is characterized in that: the material of packing core (1) is a butadiene-styrene rubber.
