Study on Surging of Blower (3rd report)

Abstract

In the 2nd report we showed a method for non-surgings of blowers by "the two-valve operation" on the delivery pipe line. In this paper we show the theoretical and experimental studies on stability or blowers, where the eliminating valve of surging is installed in the suction pipe line or close to the delivery port of blower. As the result or this experiment, it is cleared that this operating method is more useful and effective on the following points than the one mentioned before : 1. Valve loss for eliminating surging is small. 2. Both apparatus and operation are simple. 3. Method is of high stability.
