Several effective methods of cleaning bearings

wallpapers Products 2020-11-12
If the bearing is used for a long time, it will come into contact with dust, oil or water in the air, causing the bearing to become dry, rusty, and affect operation. At this time, bearing cleaning is very important.

The principle of dry ice cleaning
The temperature of dry ice particles is extremely low, so it has unique thermodynamic properties. When the dry ice particles are impacted by compressed air on the surface of the object to be cleaned, the dry ice will sublimate rapidly, and the volume will expand nearly 800 within a few thousandths of a second. Times. At the same time, heat exchange is generated with the surface of the parts to be washed to achieve the purpose of cleaning the surface of the parts.
The principle of the ultrasonic cleaning method
Using ultrasonic vibration with a frequency of tens of thousands to hundreds of thousands of times, ultrasonic waves propagate in the liquid. When the energy is greater than 0.1W/Cm2, the liquid molecules are pulled into cavities. Due to the increase in surrounding pressure, The cavitation nucleus is crushed again. When the cavitation nucleus is crushed, it forms a huge shock wave on the surrounding area, releasing huge energy, thereby stripping off the impurities on the object to achieve the purpose of cleaning.
The principle of chemical cleaning
Use organic or inorganic cleaning agents to be added to the interface of the equipment to be cleaned to disperse and strip insoluble scale, oil, biological sludge, etc., and at the same time react with chemicals to form complexes or water-soluble Sex salt, so as to achieve the purpose of cleaning.
The cleaning principle of the saturated steam method
Use the high temperature of saturated steam and the high pressure to clean the oily dirt on the surface of the part and vaporize it. At the same time, it can also clean any small gaps and holes, peel off and remove oil stains and residues, to achieve the requirements of high efficiency, water saving, cleanliness and drying.
