Lubrication of mechanical equipment is an effective way to reduce equipment wear, improve the efficiency of equipment operation, save materials and energy. Construction machinery often operates under high temperature and high load, the working environment is bad, the construction period is relatively long, and lubricating oil has higher requirements under this condition. Only when the equipment is lubricated can the machine run stably and prolong its service life.
In the introduction, installation, operation and daily maintenance of mechanical equipment, the quality and quantitative management of the whole process should be carried out to ensure that the design is reasonable, the accuracy is guaranteed, the clearance control is appropriate, the material is of high quality, lubrication and sealing is good, so as to ensure that the equipment runs under the best working condition.
How does grease work
Can hold its shape without flowing, can stick to metal without slipping. At high temperature or by external forces beyond a certain limit, it can flow like a liquid.
Grease in machinery by the shear action of moving parts, it can produce flow and lubrication, reduce friction and wear between moving surfaces.
When the shear action stops, it can regain a certain consistency. This special fluidity of grease determines that it can be lubricated in parts not suitable for lubricating oil.
Lubrication plays an important role in the normal operation of all kinds of mechanical equipment.
1) Reduce friction coefficient
By adding lubricant between two relatively frictional surfaces to form an anti-wear layer of lubricating oil film, friction coefficient can be reduced, friction resistance reduced, and power consumption reduced.
2) Reduce wear and tear
Lubricants between abrasive surfaces can reduce wear caused by hard grain wear, surface rust, bite welding and tearing between metal surfaces. Therefore, in the friction between the surface of the supply of enough lubricant, can form good lubrication conditions, avoid damage to the oil film, maintain parts with precision, thus greatly reducing wear.
3) Lower the temperature
Lubricants can reduce friction coefficient and reduce friction heat generation. That is, the work done by the running machinery to overcome the friction will all be converted into heat, part of the outward diffusion from the body, part of the machine temperature is constantly rising. A concentrated circulation lubrication system using liquid lubricants can take away the heat generated by friction and cool it down, allowing the machine to operate within the required temperature range.
4) Prevent corrosion and protect metal surface
Mechanical surface, and the surrounding medium inevitably contact (such as air, humidity, corrosive gas and liquid, etc.) so that the metal surface of the machine rust, corrosion and damage. Especially the high temperature workshop and chemical plant of metallurgical plant corrosion wear is more serious.
