Failure Analysis of Belt Conveyor system in a Thermal Power ... - ijater

International Journal of Advanced Technology & Engineering Research (IJATER)b. Bearing used to ball bearing support, plasticsealing ring labyrinth seal structure, this canensure roller worked reasonable force, whileensuring dust effect good, resistance small, easyassembly and disassembly, easy to maintain,reduce conveyor operating costs.c. For gearboxes (geared wheel and bearing) andpulleys (bearings) may use a vibration measurebased techniques [2] and temperaturemeasurement for bearing.d. For idler condition thermography measurementor noise may be used [13].e. For belt with steel cords nondestructivetechniques may be applied(measurement ofmagnetic field of steel cords)[14].for belt jointfor condition measurement some magnetic fieldsource may be placed in a joint area and by themeasurement of magnetic field the distancebetween these points may be easily calculated[15]. In order to detect cut of cover it wasproposed by one of belt produce to place kind ofelectromagnetic field transmitter. If belt is cut,electric circuit will be damaged and transmitterwill stop working [16, 17].ConclusionWide ranges applications of belt conveyors, and the workenvironment is generally more difficult, to keepequipment running in good working condition, extendequipment life, improve the quality of operation, reduceoperating costs has been the goal of engineering andtechnical personnel. Analyze and resolve the impactnormal operation of the main problems, to ensure thegood functioning of device, it is an important work ofequipment maintenance. This paper analyzes the proposedmethod. Helpful improve site maintenance staff levels tosolve practical problems, for practical project hasimportant significance.REFERENCES[1] Belt conveyor for bulk materials, fifth edition.
