A method for controlling an oil pump by means of one of the oil pump upstream frequency converter and control system

摘要

In order to achieve a method and a control system for the adjustment of the delivery rate of an oil pump (11) for the operation of an oil filter (13), wherein a installations wear is reduced and a premature oil change or a premature exchange of filter elements for the lowering of the operating costs are to be avoided, a method is proposed in which the through the oil pump (11) by an amount of oil delivered to the oil filter (13) is dependent on the determined pressure difference, the constant or is held in a predetermined pressure.In addition, a control system is proposed which a control module (19), a frequency converter (20), an oil filter (13), a by means of an alternating current motor (21) powered oil pump (11) as well as a sensor system for determining a differential pressure has.
