Now the material of water ring vacuum pump is generally is cast iron, after long time use, can produce rust, because wear or corrosion after this happens a lot of people don't care, but if the long-term rust, affects the service life of water ring vacuum pumps, water ring vacuum pump actually rust basically has the following several reasons.
The main causes of water ring vacuum pump rust
1. After a long time of use, the coating on the surface of the water ring vacuum pump is blown by wind, exposed to sun and rain, and falls off after aging. It will also lead to equipment rust.
2, often rain lead to damp air will also lead to rust, once it rains, rust will be affected by the environment, rust will flow to the surface, rust traces, a long time will cause a large area of modification.
3. When installing, because the construction personnel do not pay attention to, the antirust coating of the vacuum pump is damaged, and the place where the guide loses protection will be corroded by water vapor or acid and alkali solvent, which will seriously lead to rust wear and affect the use of the equipment.
4, the pH value of human sweat is 5~6, will also cause water ring vacuum pump rust, so to avoid direct hand touch, should wear gloves or wipe sweat with a towel.
These are the main reasons for water ring vacuum pump rust. Therefore, many types of vacuum pumps are now made of stainless steel, which greatly reduces the possibility of rust. In the future, if rust is found in the process of use, it can be removed in time to prolong the life of vacuum pumps.
