ABSTRACT:
A surge control system for dewatering press felts on a papermaking machine which includes a suction pipe, a variable speed drive motor, a centrifugal exhauster driven by the variable speed drive motor and connected to the suction pipe to provide vacuum to a felt passing over a slot for dewatering thereof. A surge valve is provided and is opened to admit air to the centrifugal exhauster so as to prevent surge when the centrifugal exhauster is operating at a predetermined level at which the centrifugal exhauster will surge.
