一、引言上海显像管玻璃厂锥生产设备在运转时,锥模具必须用高速气流冷却,使其温度保持在400℃左右。锥模中碎玻璃也必须吹净,以免影响产品质量。完成这2项功能是靠一种特殊的高气速喷嘴。喷嘴的出口外径只有4分(英制),气源分别为100磅和50磅压缩空气。喷嘴的内部相当于一个拉伐尔管。

I. Introduction Shanghai pyramid glass factory cone production equipment in operation, the cone mold must be high-speed airflow cooling, so that the temperature maintained at about 400 ℃. Cone mold broken glass must also be purged, so as not to affect product quality. The two functions are accomplished by a special high-velocity nozzle. The outer diameter of the nozzle outlet only 4 minutes (inch), respectively 100 pounds of gas and 50 pounds of compressed air. The interior of the nozzle is equivalent to a Laval tube.
