How to Avoid suddenly damage ??!!!

How to Avoid suddenly damage ??!!!

In new cement plants there are more than one unit for mega planetary gear unit

because cement manufacturers trends directed to vertical mills than horizontal

 

my friend has directed to me some explanation need to clearfy by your suggestions so let me ask some questions and kindly I need your support to tell me your experience  in this topic

1- How to make oil analysis results so effective and actual for this gear unit if you know that gear unit take more than 8000 liter

How to make oil sample is represent actual indication for any malfunction???

2- if there are signs for pitting and there are unusual sound heard when it is running

How could I fix  this problem in planning maintenance not corrective action ??

In your opinion kindly let me know what is the longest period could I keep mill running by this error ??

3- Are there any necessity to add magnetic filter to prevent debris to circulate inside hydraulic system ? 

4- There are new surface technology from Rewitec company to fix any pitting signs 

Do you know this technology valid or not in our case ?

5- I so sorry when I have told you that all new electronic technologies for predicting any malfunction still far from reliability 

if you know our inquire case has remote control for monitoring and predict faults through manufacturing company 

a lot of thanks for your share opinions in this topic

As previously mentioned Online Condition Monitoring Systems will help you to avoid failures and unplanned stoppages at gearboxes. For VRMs it is strongly recommended to monitor vibration, torque and process continously. The monitoring of vibration will detect failures at gears and bearings. The torque monitoring detects overloads, shocks and unstable process conditions, which will even proactively reduce failures on your machine; the correlation of the torque with the process helps to detect root causes of anomalies. An oil particle counter helps to make failure predictions even more reliable; especially for sleeve bearing gearboxes.

Almost regardless what brand of both gears box and grinding application the opreation patteren of the mill cou?d indicate what life the gearbox " live" a wrongly adjusted and operated mill will often increase the stress and load to the limit. The oil analysis in i my world mandatory
