Also keep a check on the commutator to ensure it doesnt have any dents, grooves, or scratches. Use the coupon code FT25 at the checkout page. Preventive maintenance includes monitoring the insulation condition of insulated motor windings. The brushes must ride on the commutator smoothly with little or no sparking and no brush noise (chatter). Dirt and grease buildup on the motor or its windings can also result in insulation failure. The Initial Inspection must be performed when the equipment is installed and whenever repairs are made to critical load-bearing components. This pertains to any equipment that uses an electric motor as its driver. Examples of these are pumps, fans, blowers, and compressors. And as previously mentioned, these are connected to the motor control centers. Below are the maintenance procedures based on the electrical equipment & maintenance checklist: Refer to BS/EN 60079-0 and BS/EN 60079-15. Stop the motor. An induction checklist is a well-detailed guideline outlining the activities lined up for the new employee or contractor, to ensure timely coverage of the induction process and to avoid omission or duplication of information. Checklist Highlight #1: Getting a Look at Your Propeller and Skeg Your electric motor should be lubricated on a regular basis To exercise the generator, check the fuel level and start the motor, then leave it running for 30 minutes or so to make sure its working properly. The high cost of the resultant downtime eats deeply into profits. Electrical tests are possibly the easiest to carry out (assuming that the equipment is available) because it often means there is no need to dismantle the motor; the testing can be done at the terminal box. If this does not work, consider revarnishing the motor first. Periodic preventative maintenance, or automatic (using IOT Sensors) Vibration testing can be used as an early indicator of bearing wear. Regular Lubrication. Check the fans behind the filters for accumulation of dust. 5. the motor is install in the hazardous location, the marking must be reviewed for the intended location.
