With the development of science and technology, industrial production generally tends to be automated through the control of electrical parts. The electrical part of wire-cutting machine tools is composed of machine tool circuit, pulse power supply, drive power supply and control system, etc. It is important to pay attention to moisture, especially the electrical system of industrial production equipment.
If the electrical equipment is damp, first of all, the insulation performance of the equipment will decrease and the insulation aging will accelerate. Secondly, as the humidity of the exposed metal conductor increases, the oxidative corrosion will generally increase (especially in the case of dust adhesion), causing an increase in contact resistance at the conductor connection, resulting in local overheating. Therefore, long-term electrical equipment in a humid environment, if not using moisture-proof measures, its service life will be greatly reduced, causing leakage, short circuit, resulting in serious electrical failures and accidents; when the relative humidity in the air is greater than 80%, electrical appliances organic and inorganic material components in the product will increase in weight, expansion, and deformation due to moisture, and corrosion of metal structural parts will also accelerate. The components inside electrical products are generally divided into metal and non-metal. Metals accelerate oxidative corrosion in humid environments; non-metals also accelerate corrosion in temperature, oxygen, humidity, and dust.
Therefore, measures to prevent oxidation reactions must be taken to prevent environmental factors from changing and causing damage to electrical properties due to changes in mechanical properties. Therefore, it is necessary to take measures to prevent or reduce the adverse effects of environmental conditions on the reliability of electrical products. Ensure the performance of electrical products work, increase the reliability of the product in harsh environments. Here are some tips on how to do moisture protection:
1. The electric cabinet should be sealed as much as possible, and the moisture-proof dust-proof sponge should be installed at the heat-dissipating hole, and the sponge needs to be replaced regularly;
2. Waterproof treatment of important components by spraying, dipping, potting and other processes,and using the moisture-proof protective agent of electrical equipment;
3. Use electronic components and structural materials with low hygroscopicity;
4. Invading the surface of the electronic circuit board with acrylic protective layer protective agent or silicone resin film protective agent to avoid intrusion of moisture;
5. For equipment that is not used frequently, put a proper amount of desiccant in the electrical cabinet, and then cover it with a protective cover. During the rainy season, the desiccant replacement cycle inside the electrical equipment should be shortened. The color-changing silica gel desiccant capable of being reused can be used,for one hand,the color can be discolored after being absorbed by moisture for suggestion,and for another hand,it can be recycled and dried after being air-dried to reduce the cost;
6. Clean the electrical cabinets of each workshop to ensure the cleanliness in the electrical cabinets;
7. Regularly replace some parts of electrical equipment according to actual production, especially the wires that are aged and hardened in the electrical cabinet or in the motor should be replaced regularly.
There are many heating components in the electrical cabinet of the wire-cutting machine, it is very unlikely to be wet when starting up normally. However, after stopping for a period of time, the circuit must be thoroughly inspected. Grease and moisture are the main causes of frequent electrical failure.
