Problems solved by technology

In addition, no specific waterproof measures are proposed for the insulation layer covering the heating cable
Although the heating cable installation technology provided by the heating cable manufacturer has a relatively complete monitoring and control system, its fixing method is very simple, and there are considerable defects, which often make the carefully set heating cable monitoring system fall short and cannot be fully utilized. due role
[0005] Practice has proved that imperfect installation methods will lead to frequent accidents of heating cables, greatly shorten the service life of heating cables, and have a great impact on the production order and economic benefits of enterprises

Embodiment 1

[0042] The model of the heating cable (3) is B / 1H00197SB / 120m / 6156W / 380V, which means that the cable structure is B, the number of heating cores is 1, the voltage level is 600V, the cable resistance is 0.197Ω / m, the sheath material is stainless steel, and heating resistance wire Material code B, cable length 120m, cable power 6156W, rated voltage 380V.

[0043] The installation method is as follows:

[0044]1. Remove burrs and rust spots on the surface of the pipe 6 to make the surface clean and smooth to prevent poor contact between the heating cable 3 and the pipe 6 and affect the heat transfer effect;

[0045] 2. Make a total of 158 protective tubes 1, using 0.3mm thick aluminum skin. The length of a single protective tube 1 is 2000mm, the cross-sectional shape is triangular, the angle of the apex of the triangle is 90 degrees, and the waist length of the triangle is 20mm. Remove the burrs around the protective tube 1 with a fine file to prevent scratching the outer metal ...

Embodiment 2

[0054] The model of heating cable 3 is B / 1H00328SB / 112m / 3934W / 380V, and its meaning is similar to that of embodiment 1, except that the resistance, length and power of heating cable 3 are different.

[0055] The installation method is as follows:

[0056] 1. Remove burrs and rust spots on the surface of the container shell 6 to make the surface clean and smooth, so as to prevent poor contact between the heating cable 3 and the container shell 6 and affect the heat transfer effect;

[0057] 2. Make a total of 6 protective tubes 1, using 0.2mm thick aluminum skin. The length of a single protective tube 1 is 2000mm, its cross-sectional shape is semicircular, and its diameter is 50mm. Use a fine file to remove the burrs around the protective tube 1 to prevent scratching the surface metal sheath of the heating cable 3 during construction;

[0058] 3. Lay the heating cable (3) along the container shell 6, and temporarily fix it with flexible cloth every 5 meters. When the heating ...

Abstract

The invention provides an installation method of a heating belt. The method comprises heating belt fixing, cracking prevention treatment and waterproof treatment. The installation method is characterized by comprising the following steps of: (1) fill gaps between the heating belt and a metal pipeline or a container shell with heat-conducting mud; (2) limiting the heat-conducting mud to in a certain space by using triangular or semicircular aluminum sheets; (3) fixing the triangular or semicircular aluminum sheets with toothed steel belts or iron wires; (4) manufacturing a U-shaped telescopic bending part on the heating belt at a specific distance interval; and (5) sealing all seams on an insulating layer shell with linen and epoxy resin. By the adoption of the installation method, the frequent accidents of the heating belt can be effectively controlled, the service life of the heating belt can be well guaranteed, the maintenance cost and the operation cost are greatly reduced and the stability of production is guaranteed.

Description

technical field [0001] The invention relates to an industrial heating system, in particular, the invention relates to an installation method of a heating cable. Background technique [0002] The heating cable is an insulated heating cable used in industrial heating systems. It is composed of a heating wire, an insulating layer and a stainless steel protective layer. Its structure is that the heating wire is wrapped with an insulating layer, and the insulating layer is wrapped with a stainless steel protective layer. The heating cable transfers heat through the material attached to the metal pipe or container shell metal pipe or container, so that the material in the metal pipe or container can be heated and kept at a certain temperature as required. [0003] The safety, reliability and service life of the heating cable are not only related to the quality of the selected product and the design of the control system, but more importantly, it is closely related to its installat...
