万一辅助电动通风机发生故障时,自动打开压缩空气源到射流喷射器的一种射流控制装置,目前已由英国 Haskel 能源系统有限公司研制出来。现有的系统使用的射流喷射器要求该装置连续工作,因而不断地消耗压缩空气。
A jet control device that automatically opens the source of compressed air to a jet ejector in the event of a malfunction of the auxiliary electric ventilator has been developed by Haskel Energy Systems Ltd. in the United Kingdom. Jet ejectors used in existing systems require continuous operation of the unit, thereby continuously depleting the compressed air.
