  Do’s : Ensure taking a work permit from the site in charge and conduct a Tool Box Talk. All electrical jobs to be conducted by a certified electrician. Ensure all the equipment is flameproof. Equipment that operates in three-phase power should have double neutral earthing. The use of an Earth-leakage circuit breaker is a must for all the equipment. The current rating for all equipment should not be greater than 30Amps. Ensure use of proper rating Direct On Line Motor Starter in individual machines. Ensure use of proper armored cables for the main power connection. If there are cable lying on the road crossings or pathways should be covered and concealed to protect them from physical damage. Cables without any joints should be used at all times. Cables should be laid above the ground to the maximum possible extend. Electrical connections should be kept clean, dry, and tight at all times. Ensure all power supplies are switched off from the feeder pillar immediately if the equipment...

  Inventory management & identification plays a vital role in the machinery and plant maintenance. Proper identification tags should be used to segregate the oils with respect to their shell life, usage location. Product labeling can be used to identify the following: Purchase & Delivery Date:  Label should mention the date of the purchase & delivery date of lubricants. Product Name:  It should also mention product name, brand, manufacturer Quantity:  It should also mention the quantity. Storage Location:  It should also mention the storage location of the lubricants. The products should be used in the same sequence as they are brought into inventory. (1) FIFO:  First in first out- lubricants should be taken into usage according to the date they are brought into the storage house. We can enhance the life of plant and machinery through proper maintenance, storage, marking of lubricants. Also read:  https://www.linkedin.com/pulse/storage-mana...

  It is observed across the spectrum that whenever we see issues/symptoms like: 1. Oxidized oil 2. Destructive pitting 3. Excessive vibration 4. Abrasive wear 5. Cavitation 6. Machinery abnormal noise 7. Wear debris generation 8. High running temperature We usually believe in either Repairing, Replacing, Rebuilding and Removing the affected component. However, it only subsides the symptoms temporarily. This approach is called the 4-R approach and it weeds out the issue from the surface and not at the root level and hence the problem reoccurs. Call +91 7030901266 for Mechanical Maintenance & Oil Check. However, we should aim at studying these symptoms and work on the root causes. Some of the very frequent root causes that cause the above-mentioned symptoms are: 1. Misalignment 2. Wrong oil usage 3. Moisture 4. Machinery part imbalance 5. Particle contamination 6. Air contamination Hence, we should aim at 5I approach i.e. It’s clean, It’s Cool, It’s dry, It’s aligned and balance...

  Place: A steel plant in Rourkela with production capacity - 4.5 MTPA Date of Execution: 20th July 2019 Equipment Criticality: High Background: A Steam turbine blower was to be commissioned in a steel plant by a leading EPC company, the pipelines were erected on the site and as per the Standard Operating Procedure listed by the Steel Plant Owner Company the flushing was completed with a single auxiliary pump at 1500 LPM. However, during the trial run of the turbine, the inline lube oil filters would clog very frequently and lead to halted operations. Problem Statement: Frequent clogging of inline lube oil filters were hindering the operations and delaying the steam turbine commissioning project Underlying Issues: On inspection, a root cause analysis was done and the required rate for effective flushing was calculated as 3500 LPM. The Particle contamination level was also found to be NAS 10. Hence following things were concluded: 1. The rate at which flushing was done was t...
