Abstract
The utility model provides a sealing cable for an electric diving pump, which comprises core cables, fillers and a protective sleeve, wherein the core cables are wrapped inside an insulation sleeve; the fillers are arranged among the core cables; and the protective sleeve is tightly sleeved on the insulation sleeve. The sealing cable is characterized in that the insulation sleeve and the core cables positioned inside the protective sleeve are disconnected and fixed into a whole through running tin. As the disconnected core cables inside the protective sleeve are fixedly connected into a whole through the running tin, the sealing cable removes gaps among the core cables, prevents water from transmitting into a motor through the gaps of the core cables, wraps the protective sleeve in sealing manner, removes gaps among between the protective sleeve and the fillers, among the fillers and among the fillers and the core cables, stops the water outside a motor winding lead wire and a cable connector lug, ensures sealing of the motor and greatly prolongs the service life of the motor.
Description
Technical field
The utility model provides a kind of submersible pump hermetically-sealed cable, belongs to the cable seal technical field.
Background technology
The work that pulls the plug of submersible pump, electromechanical, it is simple in structure, and is easy to use, and along with the development of motor, mechanical seal and control technology, submersible pump has had and has developed rapidly.Scope of operation submersible pump adopts the dry type electric machine structure mostly, and extraneous water can not enter motor internal.Adopt the submersible pump of dry type electric machine structure, the work that pulls the plug, the most key is the sealing of motor.Present cable seal adopts cable to add a cable seal circle mostly, and this kind sealing can only the hermetically-sealed cable sheath and the sealing of extraneous water, and the sealing that can not solve cable itself if cable has problem, will cause the damage of motor.
The utility model content
The purpose of this utility model just provides a kind of submersible pump hermetically-sealed cable that can overcome above-mentioned defective, guarantee motor safety.Its technical scheme is:
Comprise being wrapped in heart yearn, the filler between the heart yearn in the insulating case and closely being sleeved on sheath on the insulating case, it is characterized in that: be positioned at insulating case, the heart yearn disconnection of sheath, fixedly be connected as a single entity through dropping down tin.
The utility model compared with prior art, its advantage is: because the heart yearn that disconnects in the sheath is fixedly to be connected as a single entity through dropping down tin, removed the gap between the heart yearn, having blocked water transmits to motor internal by the gap of heart yearn, sealed envelope is with sheath again, removed between sheath and the insulating case, the gap between insulating case and the filler, between filler and the heart yearn, and water resistance is broken outside motor windings lead wire and cable lug, guarantee the sealing of motor, prolong electrical machinery life greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A profile in embodiment illustrated in fig. 1;
Fig. 3 is the B-B profile in embodiment illustrated in fig. 1.
Among the figure: 1, heart yearn 2, filler 3, sheath 4, drop down tin 5, insulating case
Embodiment
In the embodiment shown in Fig. 1-3: comprise heart yearn 1, the filler 2 between the heart yearn 1 that is wrapped in the insulating case 5 and closely be sleeved on sheath 3 on the insulating case 5, the insulating case 5, the heart yearn 1 that wherein are positioned at sheath 3 disconnect, fixedly be connected as a single entity through dropping down tin 4, having blocked water transmits to motor internal by the gap of heart yearn 1, guarantee the sealing of motor, prolong electrical machinery life greatly.Can be widely used in various submersible pumps such as proof submersible sand discharging pump, diving mixed-flow pump, submersible axial flow pump.
