过去检查风口漏水是靠人工进行的,其缺点是易造成不能及时发现漏水和判断不够准确,工人劳动条件也差。我厂工人经过多次试验,制成自动警报器。其原理是:当风口突然烧坏时,流入炉缸内的水骤然汽化产生高压,作用于风口出水管,此时取压口处的压力亦突然升高,使U型管内汞柱和导线接触通电,则联接的继电器,信号灯,电铃,自动发出警报信号。
In the past to check the outlet leakage by artificial, its shortcoming is easy to cause can not be found in time to find the water leakage and not accurate enough, workers working conditions are poor. I plant workers after many tests, made of automatic alarm. The principle is: When the tuyere suddenly burned, the water flowing into the hearth will be vaporized to produce high pressure, which acts on the outlet of the tuyere. At this moment, the pressure at the pressure pick-up suddenly increases, causing the mercury in the U-tube to contact with the conductive wire Power, the connected relays, lights, bells, automatic alarm signal.
