Lubrication: secret of improved overall efficiency

Though the use of a right lubricant may only seem to be a small part of a comprehensive preventive program, in reality it is not just about machine performance that ends at the manufacturing plantAirports offer enormous potential for savingsA large airport may utilise more than 20,000 gear units, for example in conveyor belts and escalators. Approximately 15,000 of them may be spur- and bevel gears with a mean power of 5 kW, and another 5,000 worm gears with a mean power of 15 kW. With some 4,000 operating hours a year and an utilisation rate of 40 per cent, total power consumption is at approximately 240 GWh.
Replacing a mineral oil with polyglycol special oil will increase the efficiency of all gears by roughly 5.25 per cent on average. The power saved thus totals 12.6 GWh—this is the annual power consumption of approx. 3,000 private households. 12.6 GWh equals 12,600 MWh. Based on India’s average mix of energy sources encompassing fossil fuels, nuclear power and renewables, that’s equivalent to the emission of more than 3,789 tonne of CO2. Based on the energy cost of Rs. 9.5 per kWh, more than Rs. 1 crore can be saved this way.
