Abstract
The utility model relates to a submersible pump cable wiring integrated seal. A cable joint is arranged in a connection box, a sealed body passing through the cable is arranged on the box cover of the connection box, the cable joint is arranged in the sealed body, each electric wire of the cable joint is stripped with each other, the sealed body is filled with insulating high molecular materials, the electric wires which are stripped with each other are isolated with each other via the high molecular materials, and a clamping cap is arranged on the jaw opening of the upper end of the sealed body. The integrated seal of the utility model can make the submersible pump cable wiring leakless, the sealing effect is good, and the submersible electric machine can not leak water when the cable is lacerated or is soaked in water, so a generator can not be burnt out because of short circuit. The whole sealing unit is integrated, the utility model has easy manufacture and processing, so the bulk production is suitable.
Description
Technical field
The utility model relates to immersible pump, the integrated sealing of cable connection on particularly a kind of immersible pump.
Background technology
The immersible pump of domestic production at present, its cable connection static seal generally adopts the packing seal mode.Though this packing seal mode is practical simple, cost is lower, exists following shortcoming:
1. the immersible pump depth of immersion is restricted, and bigger depth of immersion leaks easily, and sealing effectiveness is bad.
2. in case cable scratches or cable is invaded and ducked in drink, water will infiltrate submersible motor from cable core, cause the motor short circuit to burn, and make the user be subjected to economic loss.
The external at present immersible pump of producing, its cable connection static seal adopts the integral molded plastic sealing.Because its cost is higher, therefore do not promote at home as yet.
Summary of the invention
Task of the present utility model provides the integrated sealing of a kind of improved submersible pump cable wiring, and it is restricted that it has solved the immersible pump depth of immersion, leaks easily, and sealing effectiveness is bad, the problem that causes the motor short circuit to burn easily.
The technical solution of the utility model is as follows:
The integrated sealing of a kind of submersible pump cable wiring, cable joint is placed in the terminal box, be equipped with and wear the Seal of Cables body at the lid place of described terminal box, cable joint is placed in the seal, every wire of cable joint is peeled off mutually, be filled with the insulation macromolecular material in the seal, the electric wire of peeling off is mutually isolated mutually by the insulation macromolecular material, and friction top is equipped with at seal upper end open place.
Integrated sealing of the present utility model can make the submersible pump cable wiring can not leak, and good sealing effect when cable scratches or cable is invaded to duck in drink and all can not caused submersible motor to leak, thereby can not cause the motor short circuit to burn.
Concrete advantage of the present utility model is as follows:
1. be full of the insulation macromolecular material in the seal and between several electric wires, even cable scratches or cable is immersed in and all can cause submersible motor to leak in the water.
2. seal can be connected on the connector cover with bolt, and with the sealing of O RunddichtringO, installs simply, and sealing is reliable.
3. whole sealing unit is integrated, easily manufactured, and processing easily is fit to produce in batches.
Description of drawings
Fig. 1 is the structural representation of the integrated sealing of a kind of submersible pump cable wiring of the present utility model.
Fig. 2 is the structural representation of integrated another embodiment of sealing of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model is the integrated sealing of a kind of submersible pump cable wiring, and cable joint is placed in the terminal box, and the seal 3 that wears cable 2 is equipped with at lid 1 place of terminal box, and cable joint is placed in the seal 3.Every wire 4 of cable joint is peeled off mutually, and promptly the rubber skin of cable 2 outsides answers strip off to expose single electric wire 4, as shown in Figure 1, makes heat treated between the external insulation layer of single electric wire 4 and its inner wire, makes it to tighten, and can block and leak.Perhaps conductor is exposed in the further strip off of insulating barrier of single electric wire 4 outsides, as shown in Figure 2, for preventing short circuit, single electric wire 4 is answered staggered positions stripping of insulatin layer.
Be filled with insulation macromolecular material 5 in the seal 3, the electric wire of peeling off mutually 4 is isolated mutually by insulation macromolecular material 5.Be full of the insulation macromolecular material between the wire conductor among Fig. 2, can block like this and leak.The insulation macromolecular material can be made by polyamine fat or elastomeric material, adopts and fills or the high-pressure injection moulding mode.
Friction top 6 is equipped with at seal 3 upper end open places, friction top 6 by screw thread or bolted on seal 3.Because be full of the insulation macromolecular material in the seal and between several electric wires, friction top further compresses the insulation macromolecular material, makes external high pressure water to pass through.
For making seal 3 sealings more reliable, seal 3 inner chambers can be cylindrical, also can be conical.
Claims (4)
1. integrated sealing of submersible pump cable wiring, cable joint is placed in the terminal box, it is characterized in that, be equipped with and wear the Seal of Cables body at the lid place of described terminal box, cable joint is placed in the seal, and every wire of cable joint is peeled off mutually, is filled with the insulation macromolecular material in the seal, the electric wire of peeling off is mutually isolated mutually by the insulation macromolecular material, and friction top is equipped with at seal upper end open place.
2. the integrated sealing of submersible pump cable wiring according to claim 1 is characterized in that described seal is connected on the connector cover by bolt, and is sealed by the O RunddichtringO.
3. the integrated sealing of submersible pump cable wiring according to claim 1 is characterized in that described sealed body cavity is cylindrical.
4. the integrated sealing of submersible pump cable wiring according to claim 1 is characterized in that, it is conical that described sealed body cavity is.
