Condition monitoring program establishment of rotating equipment was started in this company coinciding with the start of operation of the first phase of Ilam Petrochemical Company in this year.Therefore the CM System activities for first establishment related to the preparation of rotating equipment datasheet and the initial data to determine the overall condition of rotating…
Vibration analysis and balancing also check of alignment was done on the compressor C-501 by Laser alignment system. Also doing vibration analysis on the electromotor P-471A .
Provide services to the Cement Factory of Kangan: – Performance vibration analysis and diagnostics for about 35 cases of rotating equipments – Performance balancing of rotating equipments – The natural frequencies and modal analysis and corrective offers for fan foundation by ABAQUS software
Introduction Vibration analysis is one of the most effective methods in condition monitoring. Many of faults and defects can be distinguished using vibration analysis technique. Knowing the machine geometry, specifying the measuring points, frequency range setting, and having technical knowledge for diagnostics are of the most important parameters in machinery fault detection. Many of faults…
introduction Condition monitoring is growing coincident with growing industries. Electrical motors are the most common machines which are used in different industries. So monitoring of these machines can be effective enough in decreasing maintenance expenditures. The most common electromotors used in different industries are squirrel cage induction electromotors. In the last two decades, different diagnostics…
introduction Gears are of the most common power transmitter in industries. Due to the issues which may be resulted from shocks and stresses in gearboxes, these equipment are exposed to special failures. In some cases too many gears are used in a gearbox which cannot be diagnosed easily. A vibration analyst needs to know about…
introduction Bearings are parts of equipment through which all produced forces in machinery passed. Therefore bearings are the first parts in machinery that are exposed to failures. Theoretically, a bearing has a life time of 100 years but practically this period reduced to 10 years in the best condition. To achieve this period, it’s necessary…
introduction Unbalanced rotor is one of the main reasons of vibration in rotating machinery. In order to achieve the minimum amplitude of vibration, the amount of unbalance weight should approaches to the minimum. Balancing is one of those activities which has to be done on the rotor or any other rotary parts before the assembly…
