Abstract
The utility model relates to a leading cable head for an oil submersible motor, comprising a sealing component which is arranged between a three-phase cable core and a shell, the epoxy resin filling which is casted at an end portion of the shell and the sealing stannum which is arranged between the end of the shell and the leading cable head, wherein the sealing component is composed of a sealing sleeve, a flange gasket and a plurality of sealing blocks. The cast heat-resistant index of the epoxy resin filling is no less than 180 DEG C and the end the shell is provided with a tinning layer. The utility model which is added with the tinning structure on the end portion of the leading cable head efficiently prevents the contact of the well fluid and the casted epoxy resin and avoids the softening and the lost problems caused by the reaction between the well fluid and the casted epoxy resin filling. The shell of the leading cable head is fixed with the leading cable head by the sealing stannum, which improves the fixation of a leading cable by the leading cable head and ensures the normal operation of the oil submersible motor.
Description
Technical field
The utility model relates to a kind of leader cable head of motor, relates in particular to a kind of jump lead head that is used for submersible electric machine with oil.
Background technology
The jump lead head of submersible electric pump being connected of oily jump lead and submersible electric machine with oil that be used for diving, it is installed on the submersible electric machine with oil, is connected by the lead-in wire of cable plug with submersible electric machine with oil inside winding, finishes being electrically connected.The jump lead head will have excellent sealing performance, prevents that well liquid from entering motor internal from cable end.At present, the jump lead head of use adopts the rubber blanket compression seal mostly, and the reasonable jump lead that solved enters the interior sealing problem of motor.But make the jump lead head when electric pump is worked, realize sealing reliably, also need solve the fixation problem of jump lead in the jump lead head, fixedly employing in the jump lead head of the prior art be in the jump lead method of portion's casting resin end to end, promptly allow the jump lead afterbody be full of resin, not only play the fixation of jump lead, also can play the auxiliary seal effect.But in the application of reality, find, in some oil wells, the resin of well liquid and cast reacts, make its deliquescing and loss, lost the fixedly effect of jump lead, and then destroyed the sealing of jump lead head, insulation property reduce, occur revealing, make well liquid enter submersible electric machine with oil, cause electric short circuit.Cause the damage, not normal of submersible electric machine with oil, electric pump, have a strong impact on the ordinary production of oil well.
The utility model content
In order to solve deposited in the above-mentioned prior art poor owing to jump lead head sealing, the technical problem that makes well liquid enter submersible electric machine with oil provides a kind of jump lead head that is used for submersible electric machine with oil.
The utility model is used for the technical scheme that the jump lead head of submersible electric machine with oil is achieved: it comprises the seal member that is arranged between three-phase cable core and the housing, the afterbody of described housing is cast with the epoxy resin filler, is provided with envelope tin between described housing afterbody and the leader cable head.
The utility model is used for the jump lead head of submersible electric machine with oil, and wherein, described seal member is made of sealed pressing sleeve, flange gasket and a plurality of sealing block.The heat-resistance index of described epoxy resin filler perfusion is not less than 180 ℃.Described housing afterbody is provided with tin coating.
Compared with prior art, the beneficial effect that the utility model had is: the afterbody at the jump lead head increases envelope tin structure, effectively prevented the contacting of epoxy resin filler of well liquid and cast, avoided well liquid and resin to react and softening and losing issue, and jump lead head capsule body and jump lead head are fixed together by envelope tin, strengthen the fixedly effect of jump lead of jump lead head, thereby guaranteed the operate as normal of submersible electric machine with oil.
Description of drawings
Accompanying drawing is the structure cutaway view that the utility model is used for the jump lead head of submersible electric machine with oil.
Be the explanation of Reference numeral in the Figure of description below:
1---jump lead 2---envelope tin 3---cable housing
4---epoxy resin filler 5---seal block 6---sealing blocks
7---three-phase cable core 8---flange gasket 9---sealed pressing sleeves
10---cable plug 31---afterbody of housing
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in drawings, the structure that the utility model is used for the jump lead head of submersible electric machine with oil is that the three-phase cable core 7 at jump lead 1 passes seal block 5, behind sealing block 6 and the flange gasket 8, be connected with cable plug 10, sealed pressing sleeve 9 is screwed in the cable housing 3, and seal block 5, sealing block 6 and flange gasket 8 are compressed, and can realize the sealing of jump lead 1, wherein said sealing block 6 can be a plurality of, and its quantity can be determined according to the axial dimension of housing 3; Afterbody 31 casting epoxy resin fillers 4 and envelope tin 2 at jump lead head capsule body 3, before envelope tin, need the afterbody 31 of cable end housing is provided with very thin tin layer, for example: adopt zinc-plated processing etc., make firm jump lead 1 and housing 3 are fixed together of Feng Xineng, effectively prevent contacting of well liquid and epoxy resin filler 4, and play and strengthen the fixedly effect of jump lead 1.In order to guarantee the fastness of epoxy resin filler, the heat-resistance index of epoxy resin filler perfusion preferably is not less than 180 ℃.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection of the present utility model.
