The pipe material for nozzle neck shall be seamless, unless otherwise approved by Purchaser. 设备口颈部应为无缝管材,除非买方另外批准。
Nozzle and goes neck are heated by electric heater to avoid jamming of nozzle resulting defective products. 射咀及鹅头采用特有的电加热器加热,避免塞咀而产生次品;
Too high stress in the neck of long nozzle is a major cause that results in fracture in the neck. 长水口颈部应力过大是其颈部开裂的主要原因。
Results show that reducing the apparatus size and increasing the hot air flux can effectively increase immersed nozzle's preheating temperature and improve the thermal gradient on the nozzle neck. 结果表明,缩小烘烤箱的尺寸,加大热空气的流量,可以有效地提高水口的预热温度,改善水口颈部的温度梯度。
