Diagnosis and repair of explosion-proof fans.

According to the interstate standard GOST 30852.9-2002 "Electric equipment hardened, part 10, the classification of hazardous areas" fans, as they are one of the sources of gas dilution or steam with air and the primary source of the creation of an explosive mixture are required for the production in an explosive performance. To determine the class of potentially explosive areas important factor is the direct link between the ventilation level, the degree of leakage, and its intensity, regardless of the type of ventilation used - artificial or natural.

On the basis of the hazardous area when carrying out diagnosis and repair of explosion-proof fan it is required to use the tool with a corresponding class of protection. The work on vibration diagnostics, balancing and alignment necessary to use modern analyzers manufactured and supplied by "Balteh". According to the requirements of explosion protection correspond to the following systems:

BALTECH VP-3470-Ex. Scope - according to the Ex-Marking (2Eh nA ic IIB T4 Gc X), GOST IEC 60079-14-2011.

CSI 2140 Ex. Scope - according to the Ex-Marking (2Eh ic IIC T4 Gc X), GOST IEC 60079-14-2011.

"QUANTUM-LM-Ex." Scope - according to the Ex-Marking (2Eh nA ic IIB T4 Gc X), GOST IEC 60079-14-2011.

Systems for vibration diagnostics equipment BALTECH VP-3470-Ex and Ex CSI 2140 will enable a timely manner to make the fan vibration diagnostics, to identify all the fault occurred in its core nodes to analyze and determine the severity of the problem and as the "sum" equipment for timely repair. Also, these systems allow for a fan balancing in own bearings. This procedure is carried out after undergoing weeks of Top-102 "Dynamic Balancing" and rate the TOP-103 "Fundamentals of vibration diagnostics."

Some of the most frequently detected faults are: defects of the bearing assembly, the rotor and stator of a motor fault, the fault of the fan impeller, detection of unbalance and misalignment equipment.

These analyzers allow complete control over the state of the equipment. BALTECH VP-3470-Ex will allow to conduct on Vibratory examination of database software BALTECH-Expert, on work balancing, as well as to carry out post-repair inspection control with the withdrawal of the quality of repair. Software to the CSI 2140 will allow in-depth analysis of faults, as well as allows you to automatically determine the order of 100 types of defects with the conclusion of the severity and the probability of the defect determination.

If any defect, indicating a poor state of equipment centering on the need to use the system for shaft alignment explosion-proof QUANTUM-LM-Ex. This system will allow to confirm and carry out work to address the misalignment in the shortest time. This system also works with software BALTECH Expert. This software allows the complex to assess the condition of the equipment according to several criteria: vibration diagnostics, balancing, alignment, thermal analysis, analysis of lubricants.

All of these methods will allow timely detection of faults, and most importantly to prevent an accident in the workplace, which in hazardous areas is most important and critical.
