Study on Surge-Prevention of Blower

Abstract

At present, the operation of blowers generally involves the decrease of overall operational efficiency or else it must adopt methods which are quite uneconomical owing to installation expenses etc. Recently, however, there is greater requirement for higher pressure and speed, furthermore as the tendency to automatic operation grows greater, the development and improvement of surging prevention method for safe operation becomes strongly requested. Recently, the author has made a study on surge prevention method of "two-valve operation" blower and has been able to obtain the aforementioned objectives, although not quite thoroughly. The result of this experiment clearly shows that this operating method is more useful and effective on the following matters than any published before ; 1) energy loss for eliminating surging is small, 2) this apparatus and operation are simple, 3) this method can be controlled in high stability.
