Maintenance 9.2 Inspection and maintenance NOTICE Damage to insulation If metal swarf enters the winding head when cleaning with compressed air, this can damage the insulation. Clearance and creepage distances can be undershot. This may cause damage to the machine extending to total failure. When cleaning with compressed air, ensure there is adequate extraction.
Maintenance 9.2 Inspection and maintenance WARNING Explosion hazard due to overheating of the machine caused by a layer of dust Layers of dust thicker than 5mm can insulate the machine, resulting in overheating. The maximum surface temperature of the machine cannot be adhered to. The dust can ignite, resulting in an explosion.
Maintenance 9.2 Inspection and maintenance 9.2.5 First inspection ● Check after approx. 500 operating hours, but after not more than one year: Check When the At stand- motor is still running The electrical parameters are maintained. The permissible bearing temperatures are not exceeded. The smooth running characteristics and machine running noise have not deteriorated.
Maintenance 9.2 Inspection and maintenance NOTICE Machine damage When carrying out the inspection, if you detect any impermissible deviations from the normal state, you must rectify them immediately. They may otherwise cause damage to the machine. 9.2.7 Assessing the rolling bearings To assess the rolling bearings, it is generally not necessary to dismantle the machines.
Maintenance 9.2 Inspection and maintenance 9.2.9 Maintenance intervals Please note the following in order to identify faults at an early stage, rectify them and avoid follow-on damage: ● Maintain the machine regularly and carefully. ● Inspect the machine. ● Motors must be allocated a revision/inspection number after inspection. NOTICE Motor failure Material damage can occur if the machine develops faults or is overloaded.
Maintenance 9.2 Inspection and maintenance 9.2.10 Re-greasing For machines with regreasing system, relubrication intervals, grease quantity and grease grade are provided on the lubricant plate. Additional data can be taken from the main machine rating plate. Grade of grease for standard motors (IP55) UNIREX N3 - ESSO. Note It is not permissible to mix different types of grease.
Maintenance 9.2 Inspection and maintenance 9.2.11 Cleaning Cleaning the grease ducts and spent grease chambers The spent grease collects outside each bearing in the spent grease chamber of the outer bearing cap. When replacing bearings, remove the spent grease. Note Dismantle the bearing cartridges to replace the grease in the lubrication duct.
Maintenance 9.2 Inspection and maintenance 9.2.13 Drain condensate If there are condensation drain holes present, open these at regular intervals, depending on climatic conditions. WARNING Hazardous voltage The winding can be damaged if objects are introduced into the condensation holes (optional).
Maintenance 9.2 Inspection and maintenance 9.2.15 Maintaining the external fan (forced ventilation) WARNING Rotating or live parts Live electrical parts are dangerous. Contact with them can cause death, serious injury or material damage. Before performing any maintenance work on the external fan, disconnect it from the mains, particularly before opening the terminal box.
Maintenance 9.2 Inspection and maintenance 9.2.16 Repainting 188.8.131.52 Paint finish resistant to sea air WARNING Risk of explosion as a result of processes with high levels of electrostatic charging Carefully observe the appropriate precautionary measures in order to avoid death or severe injury.
Maintenance 9.2 Inspection and maintenance WARNING Explosion hazard caused by incorrect painting The paint coat can become electrostatically charged where there is a thick coat. Electrostatic discharges can occur. There is a risk of explosion if potentially explosive mixtures are also present at this moment. This can result in death, serious injury or material damage.
Maintenance 9.3 Corrective maintenance Corrective maintenance Observe the following when carrying out any work on the machine: ● Comply with the general safety instructions (Page 11) ● Comply with the applicable national and sector-specific regulations. ● When using the machine within the European Union, comply with the specifications laid down in EN 50110-1 regarding safe operation of electrical equipment.
Maintenance 9.3 Corrective maintenance Test in accordance with the relevant EU directives after repair. WARNING Risk of explosion due to alteration of the ignition gap geometry Changing ignition gap geometries (gap dimensions) as part of repair work according to the minimum specifications of IEC / EN 60079–1 is not permissible.
Maintenance 9.3 Corrective maintenance WARNING Explosion hazard due to improper maintenance If repairs to the anti-condensation heating are not carried out correctly, e.g. if unauthorized or untested spare parts are used, this can result in explosions during operation in a potentially explosive gaseous atmosphere.
Maintenance 9.3 Corrective maintenance 9.3.4 Rolling bearings Refer to the rating plate or the catalog for the designations of the bearings being used. Bearing lifetime Prolonged storage periods reduce the useful lifetime of the bearing grease. For permanently lubricated bearings, this reduces the bearing service life. We recommend that the grease is replaced after a storage time of 12 months.
Heat up 80 ... 100 °C 184.108.40.206 Replacing bearings in explosion-proof machines ● When changing the bearings, renew the sealing rings and only use original Siemens spare parts. ● For radial sealing rings with dust protection lip (DIN 3760-AS), completely fill the spaces (100%) in the sealing ring as well as in the bearing shield hub with a suitable grease.
Maintenance 9.3 Corrective maintenance 220.127.116.11 Fitting bearings Sealing the bearings Note the following details: ● Shaft sealing rings are used to seal machines at the rotor shaft. – For V rings, comply with the assembly dimension. ● Use the specified bearings. ●...
Maintenance 9.3 Corrective maintenance Installing rolling bearings ● Extreme caution and attention to cleanliness are vital when installing rolling bearings. Observe the correct assembly sequence of the components. ● Attach all components with the specified tightening torques (Page 165). Note For further information about mounting the rolling bearing, please refer to the catalog or the information provided by the rolling bearing manufacturer.
Maintenance 9.3 Corrective maintenance WARNING Explosion hazard due to overheating of the rolling bearings If the rolling bearings are not regularly regreased, local overheating may be possible, and, as a consequence, an explosion in an explosive atmosphere. This can result in death, serious injury, or material damage.
Maintenance 9.3 Corrective maintenance ● Use a suitable tool to pull off the fan (puller). ● Locate the arms of the pulling tool in the breakout openings and slightly tension the pressure screw of the tool. ● For fans with snapping mechanisms, simultaneously release the two snap-in lugs of the fan from the annular shaft groove.
Maintenance 9.3 Corrective maintenance Observe the documentation for tightening torques of the cable entries and sealing plugs for direct mounting at the machine as well as additional glands (e.g. adapters). 9.3.8 Terminal boxes, end shields, grounding conductors, sheet metal fan covers If no other tightening torques are specified, then the values in the following table apply.
