The invention belongs to the technical field of glass production, and particularly relates to a method for improving glass production efficiency. According to the method for improving glass productionefficiency, water pressure information is acquired through a pressure transmitter, and the water pressure information is transmitted to a control system; when a control system receives a current value less than a set preset value, an alarm device is controlled by the control system to give an alarm, and simultaneously the control system controls a motor I to work; after delay, the motor I drivesa lifting rod to lift a water bag at a set speed until the water bag is lifted to a set height; after the control system controls a motor II to be delayed, the motor II drives a trolley to move to theoutside of a kiln along a track for a set length, and then the motor II is stopped. The method has the advantages of high timeliness and simple and convenient operation, and automatic monitoring of whether water is cut off or not is realized. The characteristic of high automation degree is achieved, retention of the water bag in glass liquid after water is cut off is avoided, and generation of water-cut defect glass liquid in the water bag is reduced. Simultaneously labor intensity is reduced, the production problem is solved from the source, and production efficiency is improved.
