Oil Change

The Benefits of Using our Sage Oil Vac system

• Utilizing a vacuum to evacuate the used oil from the gear box speeds up the evacuation process and allows the use of a smaller, lighter hose which puts less strain on the service winch.
• Gear pumps can contaminate the oil by introducing wear material from the gears into the oil as it pumps it up tower. We use a diaphragm pump capable of 1000psi.
• The steel tanks allow us to create vacuum in order for us to evacuate the gearbox quickly. We can also pressurize the new oil tank to force the oil into the pump, thereby preventing pump cavitations. This allows the user to change oil when the weather is cold and the oil is more viscous.
• The oil used in the gearboxes in wind turbines use a very viscous ISO 320 gear oil. By heating the oil, pumping pressures are decreased which creates a safer working environment. Another reason for heated oil is that the gearbox can operate more efficiently with less wear when the oil is introduced at or near normal operating temperatures.
• With the close tolerances inside the gearboxes, even brand new oil is not clean enough to prevent internal damage to gearbox components. Sage Oil Vac uses a CC Jensen filtration system that filters the oil to a 16/14/11 ISO cleanliness level.
• We have the capability to flush the gear box out. As drain intervals increase, the likelihood of sludge and wear particles building up in the gearbox increases. Also, some lubricants have inherent sludging problems. Without flushing the gearbox, the sludge and wear particles will stay in the gearbox and contaminate the new oil that is introduced during an oil change. If you leave these contaminants in the gearbox, they can quickly cause damage to gears and bearings and cause the gearbox to fail.
