蒸汽减温减压装置系统的冷凝水泵如何操作？

日期： 2022-09-15 作者：晟德亿编辑

蒸汽减温减压装置系统的冷凝水泵操作步骤主要有以下方面：

一、蒸汽减温减压装置系统启动前的检查

改通新蒸汽加热冷凝水系统进减温减压系统。
将减温减压系统进水管上的调节阀转入联锁控制。
关闭泵放水阀。
打开减温减压系统回流管上的手动阀。
检查泵出口所有阀门是否全部关闭。
检查出口管路是否正常。

二、蒸汽减温减压装置系统启动检查

当减温减压系统内液位正常时，打开泵进口阀。
启动泵。
打开泵的出口手动阀，气动调节阀。
重新调节各流量计、调节阀使流量适中，保持好液位。
检查泵的运行情况，调流量为刻度的50%。

三、蒸汽减温减压装置系统运行中的检查

按冷凝水泵操作规程对泵进行检查。
减温减压系统液位，及液位联锁工作状况。

四、蒸汽减温减压装置系统停车检查

当减温减压系统内无液面时，关闭去低压管网手动阀和出口排气阀，关闭减温减压系统进手动阀，气动阀，打开放水阀。
停泵
关闭泵进口手动阀，打开泵排放阀。
关闭泵出口手动阀，气动阀。
停车完毕。
