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 magnetic fluid 2 and 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 1 / 8...

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 hardener 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, t...

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 hardener 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 f...

Abstract

The invention provides a device and method for repairing broken water pipes using magnetic fluid, which includes an electromagnet prefabrication device, the interior of the electromagnet prefabrication device is filled with magnetic fluid and hardener; the iron core of the electromagnet prefabrication device is A wire is wound, and the wire is connected to the portable power supply through a sliding rheostat. This method is mainly aimed at the ruptured water pipes in the city that are exposed outside the surface and have a great impact on the lives of users. The quick and easy operation can not only repair the ruptured water pipes quickly, but also will not affect the normal life of users; the magnetic fluid with better stability is used , It also better increases the service life of the water pipe after repair; the device can be recycled and reused 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...
