Abstract
A method is provided for operating a suction device of a textile machine having a plurality of workstations wherein an air flow and a vacuum are produced with aid of the suction device. The method includes filtering the air flow with a filter element, and determining a loss of pressure or volume flow at the filter element. Based on the loss of pressure or the volume flow, an actual value is calculated for present maximum vacuum-requiring operations of the workstations that can be simultaneously executed. Based on the number of operating workstations, a setpoint value is determined for the maximum vacuum-requiring operations of the workstations that can be simultaneously executed. The setpoint value is compared to the actual value for control of the suction device.
