Abstract
The utility model discloses an isolating patch board for a submersible electric motor and an electric motor for a submersible pump, which is used for preventing the electric motor burning accident caused by water inflow or the outleakage of electric motor oil at the wire connecting position of the submersible electric motor or the electric motor for a submersible pump, wherein, the isolating patch board is arranged between the electric motor and a connection box, and the connecting points are provided with sealing rings which are connected and pressed by bolts; the isolating patch board for a submersible electric motor and an electric motor for a submersible pump is composed of a board body, an insulating body and a wiring terminal; the wiring terminal is cast on the board body by insulating substances. The utility model which can effectively prevent the accidents caused by water inflow and the oil leakage of the electric motor has the advantages of simple structure, low cost, and convenient installation and operation.
Description
The utility model relates to submersible motor and motor for submerged pump product.
Submersible motor or motor for submerged pump are worked under water, its lead fairlead sealing problem, and because of reasons such as cable end immersion oil and heating make cable expanded, very difficult realization sealing often causes dynamo oil to leak outside and motor water inlet phenomenon causes the motor burning accident.Become in the actual use often occur influence production, damnous accident.Because the expanded need of cable are often wiped out cable the end of a thread, reach 1-2 rice every year, loss also is very big.
The purpose of this utility model provides a kind of submersible motor or motor for submerged pump and prevents dynamo oil leak outside and the intake isolation patchboard of phenomenon in wiring place.
The utility model can be realized by following structure, between submersible motor and terminal box, patchboard is installed, joint has sealing ring to compress connection by bolt, and patchboard is made up of disk body, insulator and binding post, binding post by megohmite insulant with binding post and disk body cast solid.
Patchboard is made up of insulating disc, binding post and edge sealing ring, megohmite insulant and binding post cast solid, outer rim suit edge sealing ring.
Binding post has the internal plug seat that leads to the outside or is inserting column in the outside, and terminal box is equipped with inserting column or the jack that matches with it.
The utility model has following advantage:
1, can prevent effectively that dynamo oil from leaking outside and water immerses the motor damage accident that motor caused;
2, need not cut the expanded part of cable, prevent the loss of cable;
3, simple in structure, cost is low, overhauls easy for installation;
4,10 atmospheric pressure of anti-pressure ability.
Accompanying drawing 1 is the patchboard scheme of installation.
Accompanying drawing 2 is the patchboard structural representation.
Accompanying drawing 3 is a built-in type patchboard structural representation.
Accompanying drawing 4 is a plug-in type plug schematic diagram.
1 couple of embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing, between existing motor for submerged pump of producing (1) and terminal box (2), this patchboard is installed, at two-sided joint sealing ring (3) is arranged, the disk body of patchboard (4) mid portion is by insulating material, with binding post and disk body (4) cast solid, all there is pad, screw, the primary nut of common wiring at the binding post two ends as resin, nylon, plastics class.The motor lead is connected on the inboard binding post, and the outside is connected the lead of terminal box and the binding post of patchboard again, connects with bolt to compress again.Binding post is made sign in case wrong to zero line and live wire.This design is fit to existing submersible motor or the motor for submerged pump of having produced used in maintenance and installation, and original product is not needed to do any change, and installation and maintenance are convenient.
Fig. 2 is to become insulating disc (8) with megohmite insulant and binding post (6) cast solid for another kind of structure, and outer rim suit edge sealing ring (7) compresses connection by bolt.
Fig. 3 is the third structure, binding post has the internal plug seat that leads to the outside, the motor lead is connected on the inboard binding post, to isolate patchboard is fixed on the motor with counter-sunk screw, the plug that matches with jack is installed on terminal box, each plug and cable lead join, and need only during use to be inserted in electric wire connecting junction on the isolation patchboard fixing with backing-up screw or pin.
Claims (3)
1, a kind of submersible motor or motor for submerged pump are isolated patchboard, it is characterized in that between motor (1) and terminal box (2), installing and isolate patchboard, joint has sealing ring (3) to compress connection by bolt, patchboard is made up of disk body (4), insulator (5) and binding post (6), binding post (6) by megohmite insulant with binding post (6) and disk body (4) cast solid.
2, patchboard according to claim 1 is characterized in that, is by insulating disc (7), and binding post (6) and edge sealing ring (8) are formed, megohmite insulant and binding post (6) cast solid, outer rim suit edge sealing ring (8).
3, patchboard according to claim 1 and 2 is characterized in that binding post (9) has the internal plug seat that leads to the outside or is inserting column in the outside that terminal box is equipped with inserting column (10) or the jack that matches with it.
