Depending on the gauge equipment and working parameters, this standard specifies the level of vibration supported.
For safe operation at speeds higher than the current speed, it is necessary to perform the technical expertise. This expertise consists in measuring the parameters of the machine at different speeds, analyzing their evolution (graph for monitoredparameters), identification of vulnerable parts of the installation and recommendations for remediation of nonconformities. Check the technical condition of the equipment, the level of vibration, changes in temperature on the camps.
It is necessary to perform vibration measurements both dynamic and equipment of the structure on which they are located. Check the structure of the machine in terms of mechanical resistance to the new working conditions. Where it is found weaknesses of the structure, it will take measures to strengthen them.
VIBRATION DIAGNOSIS shall be determined using the necessary corrective actions to safe operation. Vibrational Spectra of the quantities collected and analyzed possible malfunction shall be identified as follows:
-Vibration-speed slimming information fixation, imbalance, they represent the wrong coupling;
Acceleration-intelligence for weakening on the shaft, power flow transmission games, free denture wear, evolving and serious wear bearings;
-Enveloping-bearing wear, start games in the early stages, games free on shaft rings, leaks, loose screws, producing loud noises;
-HFD-missing components, lubrication.
From the analysis of the vibration spectra of parameters collected, derived pointers on abnormal functioning of the equipment at risk of failure. To make recommendations for appropriate interventions for dynamic equipment with exactindication of the remedial actions.
Below I present the evolution of parameters collected at 2 speed working paper machine:
-current speed;
-speed increased.
In view of the evolution of these parameters, it is evident that the maintenance works are necessary for the operation ofequipment to remedy an acceptable level of vibration.
As a result of technical expertise for increasing the speed of the car is that corrective actions should be carried out. Statistical analysing technical problems identified, it may indicate the major factors restricting the working speed at certain values.
After removing all nonconformities, it can operate at the speed for which the technical expertise.
It is recommended that, at the new speed of operation, and carefully monitoring the tracking parameters in particular surrounding the spectrum to capture origination malfunctions.
