This new design allows more than 90% of the oil to circulate in the lubrication system and changes the oil retention performance.

This can reduce the total amount of oil in the system by 30% to 50%, thereby greatly reducing the size of the required tank and the associated oil cost. The service life of the oil is not affected in some cases. In some cases, the service life of the oil has actually increased compared to traditional lubrication systems.

Heikki Kataja, the mechatronics supervisor for the plant's mechanical maintenance, said the storage tank installed on UPM's PM 5 machine in Finland has proven to be effective.

"In 1998, we switched to a dry and thin oil lubrication system with a new fuel tank design." The reduction of 3 water storage tanks to 3 m 3 is a major advantage. Startups are going well and we haven't encountered any practical problems so far. "

Remove air and water

In the new storage tank, the water removal function has been changed.

The fuel tank has a number of intermediate horizontal plates, and its function is similar to that of the traditional fuel tank. Because the plates are placed tightly together, the water droplets in the oil droplets are guided a few centimeters before contacting the next plate to the central drain of the tank.
