Zhesen Electromechanical Open Gear Lubricant
2014/7/16
Zhesen Electromechanical had many problems in the selection of open gear lubricants before 2005.
Open gears in the cement industry are operated at low speed and heavy load, and the operating environment is relatively harsh, such as: dust, water, high temperature, long time, etc. Due to the large and heavy equipment and the flow of water, once the equipment is in trouble, it will seriously affect the production. Therefore, under the influence of many factors, the oil film of the lubrication part of the equipment requires the oil to have excellent resistance to extreme pressure, oxidation and water repellency, and has good anti-pollution ability and stability.
Before 2005, the selection of open gear lubricants was relatively random. The same open gears used a variety of brand lubricants, the same brand of lubricants used different models, and even what oil to use, different brands Model oil mix. For example, the first 2500t/d cement dry production line in Henan, which was built in 2002, used a variety of lubricants, including 460#, 680# gear oil, 220#, 320# asphalt type open gear lubricants, as well as domestic brands. Foreign brands. Due to its poor adhesion performance and low extreme pressure resistance, the open gear tooth surface is difficult to form an effective lubricating protective film under heavy load, high temperature and continuous working conditions. The tooth surface is seriously worn and the tooth surface is bright. The scratch marks and the dry bite off phenomenon, the long-term thin oil lubrication makes the wear worse, causing the gear meshing gap to be too large, and the gear vibration phenomenon begins to appear. After the adjustment and adjustment of the gears, the foreign asphalt type open gear lubricating oil was selected. This oil has strong adhesion and good vibration damping effect, but the product quality is unstable and the thermal stability is poor, especially in winter. The instantaneous gear meshing is not smooth, and the tooth surface has a bite phenomenon. This oil contains sulfide and has a corrosive effect on the tooth surface for a long time.
