Gear box oil Analysis and oil testing importance Oil analysis is not just about telling us when oil has bad condition and also tells us as proactive measures to monitoring antioxidant additive concentrations should generate activities. Despite being designed to be highly reliable, they bring about disruption and incurred costs when they wear or break due to contamination or poor operation. Oil analysis helps in detecting the developing failure conditions, and fundamentally, a majority of the gear manufacturers recommend condition monitoring, including oil analysis. Coming to oil analysis we have to consider below mentioned points. 1. Viscosity: - Viscosity is the resistanc...
Types of Bearing using in wind turbines
Types of bearings using in Wind Turbines Bearings : These bearings can support extremely heavy loads at slow speeds. They allow the transmission of both axial and radial forces, as well as accommodating tilting moments. Generally types bearing used in wind turbines are 1.Slew ring bearing for Using for Blade pitching and yawing purpose 2. Ball bearing for Generator DE & NDE side 3. Spherical roller bearing for Main bearing 4. Cylinder roller and tappered roller bearing for Gearbox internal shafts. 1. Slewing ring bearings are generally used in the pitch and yaw locations of a wind turbine, to enable the blades to rotate smoothly. These bearings can support extremely heavy loads at slow speeds. They allow the transmission of both axial and radial forces, as well as accommodating tilting moments. 2. Ball bearings are used in machines which have lot of movement in their working process. Ball bearings reduce the friction during motion,so that effic...
Ladder safety points
Ladder Safety Points Sr.No Safe Extension Ladder Use—DO: Safe Extension Ladder Use—DON’T : 1 Maintain a 3-point contact (two hands and a foot, or two feet and a hand) when climbing/descending a ladder. Place a ladder on boxes, barrels, or unstable bases. 2 Face the ladder when climbing or descending. Use a ladder on soft ground or unstable footing. 3 Keep the body inside the side rails. Exceed the ladder’s maximum load rating. 4 Use extra care when getting on or off the ladder at the top or bottom. Tie two ladders together to make them longer. 5 Avoid tipping the ladder over sideways or causing the ladder base ...
