Title (EN) OIL FILTRATION SYSTEM
(FR) SYSTEME DE FILTRATION D'HUILE
Abstract:
(EN) An oil filtration system includes three separate tanks (1,2,3) that may each contain heaters (7,8,9). A first of these tanks (1) is to receive oil from a wheel motor of the mining or construction vehicle. A second of these tanks (2) receive the oil from the first tank (1) after the oil in the first tank (1) has been suffficiently heated so as to remove moisture therefrom. And, a third of these tanks (3) receive the oil from the second tank (2) after the oil has been sufficiently filtered (4) so as to remove particles and debris therefrom. The third tank (3) can hold the filtered oil therein until it is ready to be supplied back to the wheel motor.
(FR) Cette invention concerne un système de filtration d'huile comptant trois réservoirs distincts. Le premier de ces trois réservoirs est destiné à recevoir l'huile d'un moteur de roue d'engin minier ou de travaux publics. Le deuxième réservoir reçoit l'huile du premier réservoir après élimination par chauffage de l'eau qu'elle renferme. Quant au troisième réservoir, il doit recevoir l'huile du deuxième réservoir après élimination es particules et débris par une filtration suffisante. L'huile filtrée peut être stockée dans le troisième réservoir avant réinjection dans le moteur de roue.
