在工业生产中,对蒸汽进行自动控制既是生产工艺的需要,更是节能之必需.多年来,蒸汽电磁阀由于存在这样那样的质量问题,常常装用不久就出现线圈烧毁、内外泄漏、咬住卡死、启闭失灵等问题,至使整套自控装置失去效能.这不仅造成严重经济损失,还妨碍生产正常进行. 试分析,采用电磁阀来控制蒸汽要遇到如下问题: (1)高温压力为6kgf/cm~2的饱和蒸汽温度为160℃左右,压力为16kgf/cm~2时则超过200℃.当电
In industrial production, the automatic control of steam is not only the need of production process but also the necessity of energy saving.For many years, the quality of steam solenoid valve often exists because of the existence of such kind of quality problems, Death, opening and closing failure and other issues, to make the entire set of automatic control device lost its effectiveness.This not only caused serious economic losses, but also hinder the normal production.Test analysis, the use of solenoid valves to control the steam to encounter the following problems: (1) high temperature pressure 6kgf / cm ~ 2 saturated steam temperature of about 160 ℃, the pressure of 16kgf / cm ~ 2, then over 200 ℃.
