本文介绍了渗碳炉针阀滴油器开关使用中煤油滴量随时间延长而减少的实测结果。这一客观现象是由针阀运行时间影响造成。作者分析了其规律及对渗碳工艺及质量的影响。为了消除这种影响,作者研制成一种新型煤油滴量调节和稳定装置,并已在生产中试用,取得了良好效果。 This paper describes the carburizing needle valve drip switch used in the amount of kerosene drop with time to reduce the measured results. This objective phenomenon is caused by the needle valve operating time. The author analyzes the law and the impact on the quality and process of carburizing. In order to eliminate this effect, the author developed a new type of kerosene volume adjustment and stabilization device, which has been tested in production and achieved good results.
