The reason of corrosion rust wind power bearing


wind power bearing corrosion is very common, it would reduce the service life of bearing. So everyone in daily work must pay attention to this problem.
Determine the cause and prevention method of high temperature bearing corrosion, first look at the high temperature bearing corrosion is caused by what, generally divided into external and internal. Sum up the main:
1 metal surface finish (oxygen concentration difference cell corrosion).
The 2 metal material chemical composition and structure.
Solution composition and pH 3 in contact with the metal surface value.
4 the environment temperature and humidity.
5 and all kinds of environment medium metal surface contact.
6 other people sweat also cause bearing corrosion, its pH value is 5~6. So in order to prevent corrosion caused by hand sweat, installation and production personnel should wear gloves, don't contact with high temperature Spherical roller bearings hand lightly.
