广州化工厂的一项副产品盐酸,过去采用人工灌罐。由于盐酸的挥发性和灌罐时的跑冒滴漏,危害工人健康。现在,初步试制成功了一种用射流控制的盐酸自动包装机。根据气流的特性,使气流讯号转换成电讯号,满罐后即自动关闭进料阀。这样,既减轻了操作工人的劳动强度,又防止了跑冒滴漏 Hydrochloric acid, a byproduct of the Guangzhou Chemical Plant, was used in the past by artificial canning. Due to the volatile nature of hydrochloric acid and run-time drip irrigation, endangering the health of workers. Now, a pilot trial of a success of a jet-controlled hydrochloric acid automatic packaging machine. According to the characteristics of the airflow, the airflow signal is converted into an electrical signal, which automatically closes the feed valve after the full tank. In this way, not only reduce the labor intensity of the operating workers, but also prevent the dribbling
