This article introduces the disassembly and assembly of the centrifugal oil purifier of Doosan DA30 hinged truck dump truck Doosan Diagnostic Tool UVIM Support Doosan Excavators High Quality Some of the oil passes from the main passage in the oil cooler cover to the centrifugal cleaner and then, after cleaning, flows back to the sump. Surplus oil is drained back to the sump via an overflow valve. This ensures that the pressure in the oil system is not too high. The centrifugal cleaner’s rotor is caused to spin by the force of the oil which squirts out through two nozzles at the bottom of the rotor. Dirt particles are slung against the wall of the rotor by centrifugal force and fasten there as a coating. The rotor should be dismantled and cleaned at definite intervals according to the inspection pro- gramme included in the operator’s manual. 1. Housing 2. Plug 3. Gasket 4. Spring 5. Piston 6.
