The importance of lubricants

The importance of lubricants

Case background:

Recently, our company received a piece of equipment. The customer said that the spindle disk did not move and was stuck;

Our maintenance engineers dismantled the equipment and the disassembly details are as follows:

1. The residual lubricating oil at the drive end is black in color and contains metal powder;

2. Sludge deposition at the bottom of the fuel tank;

3. The driven shaft gear end bearing is damaged, the balls are deformed, the cage is worn and missing, and the journal is worn;

4. The driven rotor gear end face frictionally collides with the gear end side plate end face;

5. The cylinder and rotor surfaces are severely rusted;

Cause analysis by maintenance engineer:

1. Deterioration of lubricating oil: The residual lubricating oil at both end caps was found to be black in color, accompanied by sludge precipitation, the lubricating oil was aging, and the replacement and maintenance were not timely;

2. Poor lubrication: The gear end bearing has dry friction marks and the balls are abnormally worn.

The role of lubricating oil

Lubricating oil plays a vital role in mechanical equipment, and its performance characteristics directly affect the operating efficiency, service life and safety of the equipment.

1. Lubrication: Form an oil film to reduce direct metal contact;

2. Cooling effect: part of the heat can be taken away during the circulation process;

3. Anti-corrosion and anti-rust: Certain additives in lubricating oil have anti-corrosion and anti-rust effects and protect the surface of parts;

4. Sealing effect: Lubricating oil can fill the tiny gaps between mechanical parts to prevent the intrusion of contaminants.

5. Cleaning effect: During the circulation process, lubricating oil can take away impurities adsorbed on the equipment and prevent the accumulation of sludge;

6. Buffering and shock absorption: Lubricating oil has a certain elasticity and viscosity, which can absorb part of the impact and vibration energy and protect bearings and gears;
