misaligned due to increasing in bearing clearances,

Big up

@ronalynaguipo9666 .. Hi, I did not get your question .. What is the problem in Thrust pad bearing? Thrust pad bearing failure in a WPU Gearbox can be caused by several factors. *Contamination and Surface Finish* are two major culprits. Dirt and contaminants can damage the bearing, while grinding marks on the face can remove the essential oil film, leading to failure ¹. *Misalignment* is another common cause. If the thrust bearing becomes misaligned, it can grind against a surface, causing "hot spots" that damage the overall operation. *Overloading* is also a significant factor, often caused by operator error or a distorted crankcase. This can lead to unnecessary wear and tear, as well as possible thrust bearing failure ¹. In addition to these causes, other factors can contribute to thrust pad bearing failure, including: - *Improper Lubrication*: Inadequate or poor-quality lubricant supply can lead to overheating and bearing failure ². - *High Loads*: Excessive loads can cause the bearing to wear down faster, leading to failure ². - *Poor Maintenance*: Failure to regularly inspect and maintain the bearing can lead to unexpected failures ². - *Design or Manufacturing Flaws*: Issues with the bearing design or manufacturing process can also contribute to failure ³. Regular maintenance, proper lubrication, and addressing alignment issues can help prevent thrust pad bearing failure. Would you like more information? Feel free to ask

@cementworld1488 as of now Sir, our VRM is shutdown but the lubrication system of running since there are still materials inside the mill, but the lubrication system is off due to fault of high pressure thrust pad alarm

@@ronalynaguipo9666 A high-pressure thrust pad alarm in the lubrication system of a WPU Gearbox indicates potential issues: 1. High thrust pad pressure: Exceeding recommended levels, potentially damaging bearings. 2. Insufficient lubrication: Inadequate oil supply or poor quality lubricant. 3. Clogged filters/pipes: Restricting oil flow. 4. Pump failure/malfunction: Inability to maintain required pressure. 5. Thrust pad wear/damage: Overheating, scoring, or excessive clearance. 6. Misalignment: Gearbox or thrust pad misalignment. 7. Overloading: Excessive loads on gearbox. 8. Pressure sensor calibration issues. 9. System contamination: Debris, water, or air in lubrication system. Alarm Thresholds* - Pressure > recommended operating range (e.g., 100-150 psi) - Pressure increase rate > set threshold (e.g., 10 psi/min) *Actions* 1. Check lubrication system for blockages or leaks. 2. Verify lubricant quality and level. 3. Inspect thrust pads for wear or damage. 4. Review gearbox alignment and loading conditions. Consequences of Ignoring Alarm* 1. Thrust pad failure 2. Gearbox damage check lubrication circuit thoroughly and instrumentation part

Thank you so much 🙂

I love 🍺 🍻, cheers 😊

@rohitgadekar1084 .. With in couples of days ,I will make one video on your doubt,

Thank you bro 😊

Problems: 1. Wear and tear: Ni-Hard bearings can wear out due to friction, leading to reduced sprocket life. 2. Corrosion: Moisture and chemicals can corrode Ni-Hard bearings, causing premature failure. 3. Overheating: Friction and misalignment can cause Ni-Hard bearings to overheat, leading to damage. 4. Misalignment: Improper alignment of the sprocket and shaft can cause uneven wear on Ni-Hard bearings. *Solutions:* 1. Regular maintenance: Schedule regular inspections and maintenance to monitor Ni-Hard bearing condition. 3. Alignment: Verify proper alignment of the sprocket and shaft to prevent uneven wear. 4. Corrosion protection: Apply corrosion-resistant coatings or treatments to Ni-Hard bearings. 5. Upgrade to durable materials: Consider replacing Ni-Hard bearings with more durable materials, such as ceramic or silicon nitride. 6. Design modifications: Optimize sprocket design to reduce stress on Ni-Hard bearings. 7. Bearing replacement: Replace worn-out Ni-Hard bearings with new 1. Monitor temperature: Regularly check Ni-Hard bearing temperature to prevent overheating. 2. Use proper shaft materials: Ensure shaft materials are compatible with Ni-Hard bearings. 3. Balance sprockets: Balance sprockets to reduce vibration and uneven wear. *Recommended Spare Parts:* 1. Ni-Hard bearings 2. Ceramic or silicon nitride bearings 3. Shaft seals 4. Sprocket segments

@@nagabhushanarao2007Thank you very much 😊

WPV gearbox How is the table above the thrust pad attached to the gear output shaft? If the table is lift then what is procedure? Plz help

Thanks for the visit

I'm so glad!

Types of mechanical seals used in pumps, 1. Pusher Seals: Most common type, uses a spring to push the seal faces together. 2. Non-Pusher Seals: Uses a metal bellows to seal, instead of a spring. 3. Balanced Seals: Designed to reduce seal face pressure, used in high-pressure applications. 4. Unbalanced Seals: Simple and inexpensive, but limited to low-pressure applications. 5. Cartridge Seals: Pre-assembled, easy to install and maintain. 6. Split Seals: Can be installed without disassembling the pump. 7. Bellows Seals: Uses a flexible metal bellows to seal, instead of a spring. 8. Diaphragm Seals: Uses a flexible diaphragm to seal, instead of a spring. 9. Lip Seals: Uses a rubber lip to seal, instead of a flat face. 10. Floating Seals: Used in applications where the shaft is subject to movement. Each type has its own advantages and disadvantages, and the choice of seal depends on factors such as: - Pressure and temperature - Pump design and application - Shaft size and material - Fluid properties - Maintenance and repair requirements
