Technical Field

The invention belongs to the technical field of submersible pump cables, and particularly relates to a water seepage prevention treatment process for a submersible pump cable.

Background

Because submerged motor pump soaks in the aquatic throughout the year, the motor is that can touch water at least, and the inside intaking of motor just can certainly burn out by short circuit, so will guarantee that water pump motor long-term operation, must guarantee that water can not get into the motor, and the immersible pump hydroenergy gets into the most common of motor is mechanical seal and cable conductor, and mechanical seal is advanced at present technology, and the probability of intaking is little again, so now as long as the cable conductor does not intake and just can guarantee water pump motor permanent operation. The cable lines then provide access to the water.

The cable is characterized in that a large rubber sheath is wrapped with 4 rubber-wrapped wires. And inside each rubber wire is a multi-strand copper core wire. When the motor operates, the temperature in the motor rises, air is exhausted along with the copper core wire after the air expands, and water vapor is remained in the motor. After the motor stops running, the air is cooled and then contracts to form a vacuum phenomenon, moist air is sucked from the outside, more water is accumulated in the motor over time, and finally the motor is short-circuited when meeting water. And after the outermost surface skin of the cable is broken, any wire is broken, water can enter the motor along the gaps of the stranded copper wires in the wire, and the motor is burnt.

Disclosure of Invention

The invention aims to solve the technical problems and provides a water seepage prevention processing technology for a submersible pump cable, which can prevent a submersible pump motor from normally running for a long time, eliminate the most common faults of the submersible pump and ensure that the submersible pump motor cannot be burnt out by short circuit when meeting water, and the technical scheme is as follows:

the water seepage prevention treatment process of the cable of the submersible pump is characterized by comprising the following steps:

A. peeling off a section of skin at the position of the cable needing waterproof treatment;

B. rotating the core wire with the surface of the cable stripped off in the positive and negative directions for several times to enable the core wire to be fluffy;

C. immersing the fluffy core wire into pasty rubber liquid, and enabling the rubber liquid to wrap each copper wire;

D. straightening the cable, and slightly screwing to ensure that the copper wires are uniformly distributed and the rubber solution is more tightly adhered;

E. rubber connectors in various shapes are die-cast on a mould on a cable wire, rubber liquid in a core wire and later die-cast rubber form a whole after heating, and the rubber is wrapped on each copper wire, so that water is prevented from permeating into the motor of the submersible pump from the copper core wire of the cable wire, and the motor is ensured not to be filled with water forever;

F. and taking out after cooling, and finishing the processing of the waterproof cable.

The purpose of rotating the core wire in the positive and negative directions in the step B is to enable the exposed core wire to be fluffy, so that the copper wires in the core wire can be separated from each other, and each copper wire in the next step can be ensured to be wrapped with the rubber solution.

The step C has the main function of wrapping the rubber solution on the copper wires, and has the effect of filling the rubber solution among the copper wires so as to block the water permeation.

The step E has the main effect that the core wire is die-cast inside the rubber connector, the rubber connector and the core wire are integrated, the part of the cable with the outer skin stripped off is separated from the whole cable by the rubber connector and rubber liquid, and therefore water is prevented from permeating into the motor through gaps between copper wires of the cable. That is, at the portion where the outer skin is peeled off, a rubber joint and a rubber liquid are used instead of the outer skin, and since it is integrated without a gap, water cannot permeate.

Preferably, in the step C, the fluffy core wire is folded and bent to form an acute angle, and then the core wire is partially immersed in the rubber solution which is formed into paste by gasoline.

Preferably, in the step D, after the cable is straightened, the cable is twisted clockwise or counterclockwise with the middle point of the exposed core wire as a fulcrum, so that the core wire is in a state of diverging copper wires to two ends of the core wire with the middle point as a bundling point.

The invention has the beneficial effects that: the anti-seepage processing technology of the copper core wire can prevent the motor of the submersible pump from operating normally for a long time, eliminate the most common faults of the submersible pump and ensure that the motor of the submersible pump cannot be burnt out by short circuit when meeting water.

Detailed Description

The following embodiments are specifically described with reference to fig. 1 to 6:

as shown in fig. 1, the sheath is first peeled off at the cable wire portion 1 so that the core wire is exposed. As shown in fig. 2, the core wire with the skin portion of the cable stripped off is rotated in the forward and reverse directions several times to make the core wire fluffy, and it can be seen from fig. 2 that the copper wires are fluffy at this time, and the copper wires have a large distance therebetween, and in this step, the best state is to make the core wire take on a spindle shape;

as shown in fig. 3, the fluffy core wire is immersed into the pasty rubber solution to wrap the rubber solution on each copper wire, before the immersion, the core wire is firstly bent to an acute angle at the middle point of the exposed core wire, then the core wire is immersed into the rubber solution, the core wire is slowly unfolded in the rubber solution to change the included angle from the acute angle to the obtuse angle, and simultaneously, the core wire is slowly lifted, so that the state shown in fig. 3 is formed.

As shown in FIG. 4, the cable is straightened and is gently twisted to make the copper wires uniformly arranged and the rubber liquid is more tightly bonded, and the cable is also slowly straightened as the core wire is continuously lifted from the rubber liquid. When the cable is pulled out of the rubber liquid, the cable is straightened, and the copper wires in the core wires are also straightened. At this time, it is necessary to perform clockwise or counterclockwise twisting with the middle point of the exposed core wire as a fulcrum, and the best state is to make the core wire take a state of spreading the copper wire toward both ends of the core wire with the middle point as a bundling point as shown in fig. 4. And then back-twisted so that the individual wires remain parallel.

As shown in fig. 5, the processed cable is die-cast with rubber connectors of various shapes, after heating, the rubber liquid in the core wire and the rubber die-cast later form a whole, and the rubber is wrapped on each copper wire, thereby preventing water from permeating into the motor of the submersible pump from the copper core wire of the cable, and ensuring that the motor never enters water;

and taking out after cooling, and finishing the processing of the waterproof cable to form the water seepage prevention cable shown in figure 6. Because the parts 1 are peeled off and then are manufactured through the process, gaps do not exist among the copper wires, water cannot permeate from the parts to the inside, and therefore the water cannot permeate into the motor.
