Centrifugal oil filter maintenance

Centrifugal oil filter, after a long time of use, its internal prone to excessive deposits and nozzle blockage. Or after the filter maintenance, the incorrect installation causes the filter function to fail. The evaluation of the work of the centrifugal oil filter is based on the speed of the rotor as the main evaluation index.

When the rotor speed is normal, the filter filter effect is the best, the rotor speed is too low will reduce the performance of the filter, and even completely lose the filter filtering effect. The speed of the rotor can be measured by a flash speedometer, or the method of measuring the free rotation inertia of the rotor can be used to check the technical status of the rotor.

Method for determining the self-used rotational inertia of a rotor

The engine is preheated after starting, so that the oil temperature reaches the normal value, and then the engine for high-speed idling, and immediately stop the oil supply, at this time in the vicinity of the reaction centrifugal filter, should be able to hear the sound of the rotor continue to rotate, from the interruption of the oil supply to the rotor stop rotating time, should not be less than 40 seconds.
