改进疏水器控制系统,提高节能效率

Improving control system of steam trap,advancing efficiency of energy saving

原195疏水器由于采用的电极是高电压电极达到700V以上,经常造成短路产生误动作,三通阀经常发卡或关不严,带动三通阀的电磁阀动作不灵活造成电磁阀吸合力阻力增大,经常烧坏电磁阀的线圈。利用蒸汽压进法,取消高压控制部分及两根检测电极,采用一个电容式液位开关代替两者功能,解决了蒸汽盘根泄漏的问题,电磁三通阀故障率高的问题,安全隐患大等问题。提高了蒸汽的利用率,节省了蒸汽,减少了浪费;减少了工人的维护量,提高了控制率。

With the high- voltage electrodes （over 700 voltage）, the 195 water dispatcher could be caused short circuit, resulting in the mechanism mis - acting. The three - way valve frequently fail to close tightly or even be blocked. The electromagnetic valve which drives the three -way valve is thus applied excessive load and its coil could be easily damaged. One solution is steam pressure control . We can use a capacitor hydraulic switch to replace the high - voltage control and the two detecting electrodes. This can solve the problem of the steam leak at the valve port and the problem of the three way valve damaging and thus greatly increase the viability. Also this can improve the steam utilization ratio and reduce the intensity of maintenance and finally promote the overall efficiency.
