What are the reasons rod mill can efficiently realize the function of the material to be ground is an essential equipment in industrial production, we must be careful in the use of the process, in fact, there are some failures can be avoided, then the emergence of a bush-burning? how to solve this problem?
First, the reasons
1, the pad surface is not formed bush-burning results in good film, run time, a thin film is required, to act as lubrication between the sliding bearing bush and the shaft. Once the lubricating effect is not good, friction occurs between the bearing and shaft generate high temperature, resulting in bush-burning phenomenon.
2, and the spherical bush does not match spherical seat bush-burning results in frictional heating. Spherical bush having automatic adjustment of the hollow shaft coaxial with the pad, when the spherical bush rod mill does not match with the spherical seat, a back spherical bush would be poor contact with the bearing seat, leading to the hollow journal tile small contact area, static load becomes large, the contact pad side local heating occurs.
3, the bearing pad wear resulting in poor sealing. The main bearing seal general use wool felt ring seal, this type of relatively poor sealing manner, easy to wear, resulting in dust from entering through the damaged gasket main bearing, and abrasive wear caused by the spherical bush oil plug.
Second, the solution:
1, the front surface of the test pad in advance of the two shower rod mill lubricant, until test is finished, to replace the need to clean the lubricating oil. Once the pad is insufficient lubricating oil supply amount or low viscosity oil film can not be formed, leading to high bearing temperature, then, in order to avoid bush-burning, and promptly stop the cooling oil change.
2, the outer spherical surface of the spherical shoe repair scraping, sanding, remains smooth so that the outer spherical surface, the concave spherical surface of the base rotating flexible, self-aligning functions.
3, during use the timely check the wear of the seal, change in time. Or choose a better seal device at the time of purchase.
great harm to the bush-burning rod mill, no doubt, in order to avoid this situation, we need to do is ground inspection, the timely replacement of parts, good ventilation cooling equipment, which can reduce the appearance of produce bush-burning phenomenon.
