Abstract
The utility model provides a but latent oily screw pump oiling cable unit, includes copper conductor, EP rubbers insulation, lead sheath, weaving layer, interior steel strip armoring, defeated oil pipe, outer steel strip armoring. The copper conductor is packed sequentially outward and has been installed EP rubbers insulating layer, lead sheath and weaving layer and interior steel strip armoring, and defeated oil pipe is installed outward side by side to interior steel strip armoring, and outer steel strip armoring has been installed to outmost parcel. The utility model has the characteristics of not only can follow ground simultaneously and regularly change lubricating oil for the reduction gear for submersible motor provides power for two tasks are accomplished simultaneously in a subjob, reduce substantially operating cost, cable flexible high, the construction operation is simple and convenient, can be in random lengths disconnection or connection, cable intensity is high, the reduction gear is longe -lived, examine that pump period is long, the effective producing days of oil well is many, efficient etc, extensively use in the latent whelk pole pump assembly of oil development.
Description
Technical field
The utility model relates to oil exploitation submersible screw pump power cable, and particularly a kind of submersible screw pump can oil filled cable device.
Background technology
The power cable that existing a kind of submersible screw pump assembly is supporting, its structure is: wrap insulate layer, restrictive coating, lapping layer form three independent heart yearns, and three heart yearn parallel arranged be arranged in steel-tape armouring layer three copper conductors respectively outward.The latent oily power cable of this structure, for oil exploitation submersible screw pump assembly power supply engineering has played effect, but it exists following shortcoming or deficiency simultaneously: the lubricating oil 1. can not filling sufficient amount in decelerator, often the accelerated wear test because lubricating oil lost efficacy, easily causes decelerator to damage; 2. cannot change in time after oil ageing in decelerator, the useful life of decelerator is low; 3. the replacing of decelerator can only be undertaken by playing lower tubular column operation, and operating cost is high; 4. play lower tubular column operation frequently and can have a strong impact on oily well yield.
Summary of the invention
The purpose of this utility model is to provide a kind of submersible screw pump of improvement can oil filled cable device; adopt steel-tape armouring in copper conductor that the combining structure of petroleum pipeline is installed side by side outward; both can be submersible electric machine with oil and power was provided; can be regularly decelerator more oil change from ground again simultaneously; effectively protect the decelerator of submersible electric machine with oil, effectively can overcome again or avoid the shortcoming that exists in above-mentioned prior art or deficiency.
Submersible screw pump oil filled cable device described in the utility model, comprises copper conductor, ethylene propylene rubber insulated, lead sheath, braid, interior steel-tape armouring, petroleum pipeline, outer steel-tape armouring.Described copper conductor is packed in turn outward and is installed on ethylene propylene rubber insulated layer, lead sheath and braid and interior steel-tape armouring, and this interior steel-tape armouring is provided with petroleum pipeline outward side by side, and outermost layer parcel is installed on outer steel-tape armouring.
Wherein, described copper conductor is three, and every root copper conductor is packaged in ethylene propylene rubber insulated, lead sheath and braid respectively becomes a phase, and three-phase is parallel to be again wrapped in interior steel-tape armouring.Described petroleum pipeline is installed on outside interior steel-tape armouring and in outer steel-tape armouring.Be installed in the outer and outer steel-tape armouring of interior steel-tape armouring described petroleum pipeline and copper conductor side by side parallel.Described petroleum pipeline is fiber reinforcement tubular construction.
The present invention compared with prior art tool has the following advantages:
1, power cable and petroleum pipeline are fitted together, not only can be submersible electric machine with oil and power is provided, can be regularly decelerator more oil change from ground simultaneously, make one-stop operation complete two tasks simultaneously, significantly reduce operating cost.
2, petroleum pipeline adopts fiber reinforced pipe material, and cable flexibility is high; Construction operation is more simple and convenient, can disconnect in random length or connect.
3, because cable adopts double armor structure, the intensity of cable itself is significantly promoted, avoids the damage to cable in operation process.
4, effectively can be improved the life-span of decelerator by petroleum pipeline periodic replacement lubricating oil, extend pump detection period, increase effective producing days of oil well.
Accompanying drawing explanation
Fig. 1 is a kind of example structure schematic diagram of the present utility model.
