Description
Technical Field
The utility model relates to a submersible pump cable sealing connection structure, and belongs to the field of cables.
Background
In order to ensure the long-term reliable operation of the submersible pump and prolong the service life of the submersible pump, the waterproof sealing performance of the submersible pump must be ensured. Mechanical sealing and cables are two major factors affecting the sealing performance of the submersible pump, the former causes small probability of water inflow of the submersible pump along with the development of a sealing process, and the current water inflow of the submersible pump is mostly caused by water seepage of the cable. The cable used by the current submersible pump mostly consists of an outer rubber insulating layer and a plurality of built-in core wires, when the submersible pump works under water after being soaked for a long time, the outer rubber insulating layer of the outer rubber insulating layer or the surface of the built-in core wires of the outer rubber insulating layer is damaged and cracked, and external water enters into a motor of the water pump along gaps among the plurality of built-in core wires of the cable or gaps among copper wires built-in the damaged core wires, so that insulation of the motor is reduced, and the motor is burnt.
Aiming at the problem that the motor burns out after the external cable of the submersible pump is soaked in water for a long time and is worn, external water enters the motor through gaps among a plurality of wires arranged in the cable or gaps among copper core conductors in a single wire, the current pump production industry usually adopts a tin dipping or soldering process at the joint of the cable of the submersible pump to prevent the water seepage of the cable, as disclosed in the Chinese patent of the current publication No. CN213070650U, the utility model is characterized in that a soldering tin layer is arranged outside a plurality of copper wires of the wires, the gaps among the copper wires are filled with the soldering tin layer, a hot melting layer is wrapped outside the soldering tin layer of the single wire (a heat shrinkage tube is commonly used in actual production), and a rubber sleeve is arranged outside the soldering tin section of the plurality of wires, so that the wires, an insulating layer and the rubber sleeve are tightly and gaplessly in the radial direction, thereby preventing the water from entering the motor from gaps between the wires of the cable or the copper wires in the single wire, and the motor from burning out.
However, in the actual production of the cable structure, in order to make the rubber sleeve sleeved outside the core wire soldering tin layer section tightly fit and not easy to age, a pump manufacturer usually adopts a rubber vulcanization process to place the rubber sleeve outside the core wire, namely, the core wires with soldering tin layers formed at the joints are placed in a die cavity as shown in fig. 1, rubber and vulcanizing agent are injected into the die cavity, the outer parts of the plurality of core wires are pressed into an integrally formed rubber sleeve at 160 ℃, in the vulcanization process, the prefabricated hot-melt layer (heat-shrinkable tube) of the core wires is extremely easy to age after secondary shrinkage at 160 ℃ due to the normal melting point of the hot-melt layer (heat-shrinkable tube) at the vulcanization process, the soldering tin sections of the adjacent core wires are easy to expose, meanwhile, the vulcanization process is carried out at high pressure, the rubber in the die cavity drives the core wires to creep, so that the plurality of core wires in the rubber sleeve are extruded with each other, and further the soldering tin layers of the core wires in the cable are relatively close to each other, so that the insulation performance of the cable is relatively poor, and the potential safety hazard exists in the use of the submersible pump.
