Water ring vacuum pump is a vacuum pump used for pumping underground methane, and there are many corrosive substances in biogas. In order to make the equipment work normally, we need to solve the corrosion problem. Here are some measures to solve the corrosion problem
1. At present, the application of polymer composite repair materials for surface organic coating is one of the best anti-corrosion measures.
All sided corrosion is the whole of the equipment, and local corrosion occurs locally, such as pitting corrosion, crevice corrosion, intergranular corrosion, wear corrosion, delamination corrosion, stress corrosion cracking, corrosion fatigue, hydrogen corrosion cracking, etc.
3. Repair method:
If the surface is cured with acetone, the surface should be treated with water.
2. The curing time shall be shortened by half, but the rising temperature shall not exceed the bearing temperature of the material. The temperature of the material shall be kept at 24 hours / 24 ℃, and the material temperature shall be increased by 11 ℃.
3. Install according to the assembly requirements. If the material affects the assembly, the grinding method can be used. Do not knock it to avoid damaging other materials. However, it should be noted that the repaired materials should be protected to avoid being knocked or impacted by external forces.
Compared with the traditional welding repair of pressure vessels, the surface adhesive coating protection is more convenient and the cost is relatively low. It can be widely used in the repair of abrasion, cavitation and corrosion parts and pre protection coating, and the repair effect is ideal.
Water ring vacuum pump works in high temperature and high pressure environment for a long time, so it is easy to be corroded by the air, resulting in wear, corrosion, leakage and other phenomena. Therefore, we should do a good job of its corrosion protection before use and when working, so as to avoid unnecessary trouble and improve work efficiency.
