Description
Technical Field
The utility model relates to a immersible pump technical field specifically is a novel integration cable joint's immersible pump.
Background
The submersible motor works underwater for a long time and has strict sealing requirements. In particular, the sealing requirements of the motor cable are more strict. The connection and sealing of the cable directly affect whether the submersible pump can operate safely for a long time.
1. Surface radial sealing of cables
The traditional sealing mode is that a metal plane extrudes a filler or a rubber material with plastic deformation at a sealing part, and a gap at the sealing part is eliminated to achieve the effect of blocking the medium flow. For a small-power submersible motor, the sealing effect can meet the requirement in a short period due to the fact that the cable diameter is small (the cable diameter is less than 20-30 mm), but for a large submersible pump, the elastic range of a cable rubber sheath is enlarged due to the fact that the cable is thick, the cable is in a shaking state in water for a long time in the working process of the water pump, and the radial extrusion sealing mode is adopted, so that the cable is prone to failure and poor in reliability.
2. Internal sealing of wire core
The inside sealing of copper conductor is considered seldom in traditional sealing, the inside leakage risk of copper conductor can't be thoroughly eliminated, and water enters into inside sinle silk very easily, has serious potential safety hazard, shuts down outside water after especially the cable runs for a long time and slowly leaks to inside the cable or the damaged risk that finally causes the motor to damage of cable. In addition, air leaks from the wire core, so that an air tightness test is difficult to perform after assembly, and the air tightness of the motor wiring cavity cannot be verified.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems existing in the background technology, the utility model provides a novel submersible pump with an integrated cable joint, which changes the radial seal into the axial seal; and a specially-made partition type wire pressing connecting pipe is adopted, so that the risk of wire core leakage is thoroughly blocked while the cable is connected safely and reliably.
The utility model provides a technical scheme that its technical problem adopted is:
a novel submersible pump with integrated cable joint comprises:
a cable;
the lower end of the integrated sealing structure body is inserted into the cable seat;
the cable sealing gland is sleeved on the cable, a cavity for accommodating the integrated sealing structure body is formed in the lower end of the cable sealing gland, and the lower end of the cable sealing gland is fixedly connected with the cable seat through a bolt;
the cable clamp is arranged on the cable sealing gland and is fixedly connected with the cable clamp;
the integrated sealing structure body is provided with a flange, the flange is clamped between the cable sealing gland and the cable seat, and the flange is connected with the cable seat in a sealing way;
the wire pressing connecting pipe is connected with a wire core of the cable.
Further, the integrated sealing structure body is formed by vulcanizing rubber at high temperature through a die.
Furthermore, the core of the cable is cut off, and a partition type wire pressing connecting pipe is adopted for re-crimping.
Further, the cable gland is connected with the cable and the cable seat in a sealing mode.
The utility model has the advantages that:
this structure easy operation to no matter the cable has any damage, can both prevent effectively that water from permeating to the submerged motor inside, with low costs, the time limit for a project shortens greatly, is particularly suitable for the reliable sealing under the thick condition of high-power immersible pump cable, adaptation market demand that can be better.
(1) The integrated sealing structure adopts an axial sealing mode, so that the strength of a cable sealing part is increased, and the water seepage after the cable is damaged is thoroughly prevented.
(2) The cable gland and the cable clamp play a role in fixing and sealing, and a stress surface is increased.
(3) The special partition type wire pressing connecting pipe thoroughly prevents water seepage from the copper core.
(4) The air tightness test can be carried out, and the assembly quality of the submersible pump can be reliably verified and guaranteed.
Drawings
The present invention will be further explained with reference to the drawings and examples.
