Problems solved by technology

But when it is necessary to continuously repair long-distance pipelines, or when there are multiple problems in the pipeline including material, changing the pipeline may be the only option
After many years of operation of various pipelines, due to corrosion, poor operation management and other reasons, various damages and leakages will inevitably occur, which will bring serious economic losses. Long project period

Embodiment 1

[0044] see Figure 1-4 , a device for repairing broken water pipes using magnetic fluid, which includes an electromagnet prefabrication device 1, the interior of the electromagnet prefabrication device 1 is filled with a magnetic fluid 2 and a hardener 6; the iron core of the electromagnet prefabrication device 1 is outside A wire 4 is wound, and the wire 4 is connected to the portable power supply 3 through a sliding rheostat 9 . By adopting the above-mentioned device, the caliber of the device can be changed according to the size of the ruptured water pipe to be repaired, and the purpose of repairing the water pipe can be achieved by utilizing the principle of magnetic fluid sealing.

[0045]Further, the electromagnet prefabrication device 1 is assembled from several identical parts. The parts are divided into upper and lower parts, which are connected by welding through the middle part. The upper part is an iron core, and the lower part is composed of poles. Each part is a...

Embodiment 2

[0054] A method for repairing a water pipe using a device for repairing a ruptured water pipe with magnetic fluid comprises the following steps:

[0055] When the pressure against a ruptured water pipe is small:

[0056] Step1.1: Prepared materials: Prepare the parts of the electromagnet prefabrication device 1, the magnetic fluid 2, the sliding rheostat 9, the coagulant 6, the wire 4 and the portable power supply 3;

[0057] Step1.2: Assemble the device: connect the two parts with pins according to the size of the broken water pipe in the place where the water pipe is not leaking, and so on, assemble the complete electromagnet prefabricated device 1, and connect the portable power supply 3 The wire 4 of the negative pole is wound on the outside of the device;

[0058] Step1.3: Magnetic fluid seal: move the device to the place where the water pipe is broken, then turn on the power switch, adjust the P of the sliding rheostat 9 to the place with the smallest resistance value, ...

Embodiment 3

[0063] When the pressure against a ruptured water pipe is high:

[0064] Step2.1: Prepared materials: prepare the parts of the electromagnet prefabrication device 1, the magnetic fluid 2, the sliding rheostat 9, the coagulant 6, the wire 4 and the portable power supply 3;

[0065] Step2.2: Assemble the device: connect the two parts with pins according to the size of the broken water pipe in the place where the water pipe is not leaking, and so on, assemble the complete electromagnet prefabricated device, and connect the positive and negative poles of the portable power supply wires wrapped around the outside of the device;

[0066] Step2.3: Form the magnetic fluid sealing ring: turn on the power, adjust the resistance of the sliding rheostat to the maximum, and then inject the magnetic fluid from the injection hole until the magnetic fluid sealing ring is formed;

[0067] Step2.4: Repair the water pipe: move the electromagnet prefabricated device that has formed the magnetic ...

Abstract

The invention provides a device and a method for repairing a broken water pipe through magnetic fluid. The device comprises an electromagnet prefabricating device, wherein the electromagnet prefabricating device is filled with the magnetic fluid and a hardening agent; and a wire is wound outside an iron core of the electromagnet prefabricating device, and the wire is connected with a portable power source through a slide rheostat. The method mainly aims at the broken water pipe which is exposed outside the ground surface and has a great influence on the life of a user in a city, is quick and simple to operate, can quickly repair the broken water pipe, and does not influence the normal life of the user; the magnetic fluid with better stability is adopted, so that the service life of the repaired water pipe is better prolonged; and the device can be recycled after the water pipe is repaired.

Description

technical field [0001] The invention relates to a device and method for repairing broken water pipes by using magnetic fluid, which belongs to the technical field of water pipe repair, and is especially suitable for repairing water pipes that cannot be cut off. Background technique [0002] Pipeline repair technology has largely emerged as urban infrastructure ages, which sometimes break down without warning. As a result of the damage, the operation is interrupted, and the pipeline owners not only have to bear huge economic losses, but also the relevant parties have to bear great public pressure. Replacing the water pipe can solve all the problems in the repair section at once, and it is permanent. However, pipe replacement repair also has obvious disadvantages. The pipeline company must stop production during construction work, which will have a certain impact on downstream users. The replacement of pipelines is not only expensive, but also brings environmental and social...
