Poor lubrication and pollution are important reasons for equipment failure:

1, 70% of the failure of the equipment is caused by abnormal wear caused by lubrication failure;

2, about 40% of the failure and damage in rolling bearings are caused by improper lubrication;

3, about 51% of the faults in the gear are related to poor lubrication and abnormal wear;

4, about 70% of the failure of the hydraulic system comes from the pollution of the hydraulic medium, and the pollution level is too high.

Good lubrication and contamination control are essential to the proper operation and extended service life of the equipment. Understanding the different types and methods of lubrication can effectively avoid the risk of equipment failure. Here are some common types and methods of lubrication, along with advice on how to deal with equipment failure:

1. Lubrication

Lubrication is the act of adding special substances between relative moving surfaces to reduce surface friction and material loss.

1.1 Purpose of lubrication

Lubricants are added between the relative moving surfaces of the friction pairs of mechanical equipment to reduce friction resistance and energy consumption, reduce surface wear, extend service life and ensure the normal operation of the equipment.

1.2 Type of lubricant

Lubricating oil, grease, solid lubricant.






■ Film thickness depends on velocity, viscosity and load (5-2ooum);

■ At lower speeds, there is boundary lubrication when starting and stopping (metal and metal contact);

■ Particles and water vapor pollution damage the lubricating oil film;

■ Application examples include: plain bearing, piston and cylinder contact, sliding CAM contact and inclined slide plate contact;

1.5 Troubleshooting Device Failures

Oil analysis: The use of online oil monitoring system, comprehensive monitoring of the physical and chemical properties of lubricating oil, as well as impurities, metal particles, etc., to predict potential failures.

Maintenance records: After the data collected by the monitoring system is transmitted to the oil Cloud iot platform, operation and maintenance personnel can query historical data, record lubricant replacement and maintenance, and track equipment status changes.

Training and awareness: Train maintenance personnel on proper lubrication methods and management to increase their awareness of the risk of equipment failure.

Emergency plan: Prepare an emergency plan in case of unexpected equipment failure, including spare parts, spare lubricants, etc.

By understanding the different types and methods of lubrication, as well as taking appropriate maintenance measures and preventive measures, you can more easily cope with the risk of equipment failure, extend the life of your equipment and improve the reliability of your equipment.
