Abstract
The utility model discloses a lead cable for an oil submersible pump, comprising three conductors. The outer sides of the three conductor are respectively wrapped by anti-compression layers, the anti-compression layers employ flame retardation thermoplastic polyurethane elastomers, the outer side of the three conductors wrapped by anti-compression layers is wrapped by an inner water proof layer, a winding and cladding layer, an outer water proof layer, an inner protective sleeve layer, an armored layer and an outer protective sleeve layer in sequence from inner to outer, and a plurality of tension resistant steel wires are provided along the annular direction in the outer protective sleeve layer. According to the utility model, the structure is novel, the elastomer anti-compression layers are additionally provided between the conductors and th einsulating layers, the anti-compression and flame retardation characteristics of the cable are enhanced, in addition, water proof layers are provided in and out of the winding and cladding layer out of the cable core, tension resistant steel wires are provided in the outer protective sleeve layer of the cable, thereby the waterproof, tension and warp resistant characteristics are obvious raised, the lead cable for an oil submersible pump can be applied in a severe environment, and the electric power transmission safety is guaranteed.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of oil-immersed pump jump lead.
Background technology:
Oil-immersed pump full name oil-submersible centrifugal pump is a centrifugal multistage pump multiple centrifugal pump, mainly by the multistage centrifugal impeller, lead shell, pump shaft, pump case and last lower contact etc. and form.The more piece pump can be through connecting flange and spline housing serial connection, to satisfy the needs of lift.
Oil-submersible centrifugal pump can adapt to dissimilar oil wells.The impeller of nihard and the pump shaft of leading shell and K-500 monel metal can make pump under the intensity of maximum and load, arranged satisfied running life.For carrying and the simplification assembling that adapts to oil well hole condition, parts; Multistage centrifugal pump adopts three kinds of full floating, total head compact form or semi-floatings on assembling form; Structurally be divided into radial flow and mixed flow, on purposes, be divided into standard pump, sand-preventing pump, corrosion protection pump.
In people's production process, not only need also need the auxiliary element of pump be optimized paying attention in the pump body structure design, the jump lead of oil-immersed pump needs to pay attention to equally.
Original cable is relatively poor in combination property, and promptly anti-extrusion, the fire resistance characteristic of cable, warp resistance characteristic or the like factor is comparatively weak, causes electric power transfer safety to can not get ensureing, has caused a certain amount of property loss.
The utility model content:
The purpose of the utility model provides a kind of oil-immersed pump jump lead; Be applicable to being connected between ac rated voltage 3.6/6KV and following oil-immersed pump unit and the oil-immersed pump motor, solved cable because the problem of the electric power transfer obstacle that anti-extrusion performance, water resistance, warp resistance poor-performing are brought.
The utility model technical scheme following:
The oil-immersed pump jump lead; Comprise three conductors; It is characterized in that: three conductor outsides are enclosed with the resistance to compression layer respectively, and the resistance to compression layer adopts fire-retardant thermoplastic polyurethane's elastomer, and the resistance to compression layer outside is enclosed with insulating barrier; Three conductor outsides of wrap insulate layer are enclosed with inner waterproofing layer, lapping layer, exterior waterproof coating, inner restrictive coating, armour, external sheath layer successively, are provided with several tension steel wires along circumferential direction in the external sheath layer.
Described oil-immersed pump jump lead is characterized in that: described insulating barrier adopts polyimides-F46 composite membrane or ethylene-propylene rubber.
Described oil-immersed pump jump lead is characterized in that: described inner waterproofing layer, exterior waterproof coating adopt the overlapping wrapped formation of multilayer waterstop.
Described oil-immersed pump jump lead is characterized in that: described armour adopts the overlapping wrapped formation of multilayer steel band.
The utility model novel structure; Between conductor and insulating barrier, set up elastomer resistance to compression layer, improve the anti-compression property and the flame-retarding characteristic of cable effectively, the outside is provided with watertight composition in the lapping layer in this external cable core outside; Tension steel wire in the cable jacket layer; Make that fire resistance characteristic, the tension warp resistance characteristic of cable are obviously promoted, can adapt to comparatively rugged environment use down, ensured electric power transfer safety.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
The oil-immersed pump jump lead; Comprise that 1, three conductor 1 outside of three conductors is enclosed with resistance to compression layer 2 respectively, resistance to compression layer 2 adopts fire-retardant thermoplastic polyurethane's elastomer; Resistance to compression layer 2 outside are enclosed with insulating barrier 3; Three conductor 1 outsides of wrap insulate layer 3 are enclosed with inner waterproofing layer 4, lapping layer 5, exterior waterproof coating 6, inner restrictive coating 7, armour 8, external sheath layer 9 successively, are provided with several tension steel wires 10 along circumferential direction in the external sheath layer 9, and insulating barrier 3 adopts polyimides-F46 composite membrane or ethylene-propylene rubber; Inner waterproofing layer 4, exterior waterproof coating are adopted the overlapping wrapped formation of 6 usefulness multilayer waterstops, and armour 8 adopts the overlapping wrapped formation of multilayer steel band.
In addition, answer points for attention in the laying installation process of cable: cable is minimum to lay temperature-30 ℃, and the minimum bending radius 500mm of cable, cable should be parallel to oil pipe and tie up firmly, and cable is gone into the well or is strictly on guard against during gug to beat and turns round or damage.
