本手册给出了S-600水汽取样装置的日常维护的方法。

This manual contains normal ways regarding S-600 water and steam sampling devices.

本手册适用于S-600水汽取样装置在现场的日常维护。

This manual is suitable for maintenance of S-600 water and steam sampling devices.

2 装置的维护

2 Maintenance of devices

2.1 若出现某路样水温度偏高

2.1 I f the temperature of one sampling water on high side

2.1.1 检查排污门是否关严或是否泄漏。

2.1.1 Check the blow-off doors whether closed strictly or leak.

2.1.2 检查恒压装置安全阀是否打开。

2.1.2 Check the safety valves of constant pressure device whether open or not.

2.1.3 检查冷却水是否中断，盘管是否结垢。

2.1.3 Check the cooling water whether cut off or not, and whether there is impurity in coil.

2.1.4 检查盘管是否泄漏。

2.1.4 Check the coil whether leak or not.

2.2 若出现某路高压排污管温度较高，此时检查人员可用手轻握该路样水的排污管，并将其与其它样水的排污管温度相比较，若温度异常可断定排污阀

未关严或排污阀已经损坏，维护方法参照高压阀的维护方法进行维护。

2.2 If the temperature of one high blow-off pipe is higher than others, the inspector could hold this pipe and compare with others on temperature, and by experience he could judge the blow-off is unclosed fully or bad. Then the maintenance way could regard the ways of high pressure valves.

2.3 装置维护时注意事项：

2.3 Matters needing attention on maintenance ：

2.3.1 高压阀维护时，必须关闭样水进口阀门。

2.3.1 The water sampling inner valves should be closed when maintain the high pressure valves.

2.3.2 冷却器维护以及更换冷却器盘管时，关闭样水门，关闭冷却水进出球阀。

2.3.2 Close the water sampling doors and in-and out cooling water ball valves when maintain and change the cooling coil.

2.3.3 清洗恒压装置、保护装置时关闭样水进口阀门。

2.3.3 Close the sampling water inner valves while wash the constant pressure devices and protecting devices.

2.3.4 更换水样过滤器滤芯时，关闭仪表样水进口节流阀。

2.3.4 Close the inner throttle of water sampling meter as change the filter element.

3主要零部件的维护

3 Maintenance of main parts

3.1高压阀（316NB-GM）

3.1 High pressure valve s（316NB-GM）

运行人员按照操作指南对高压阀进行正确操作，可确保高压阀可靠运行，高压阀维护主要维护事项如下：

Be sure on safety running under operating as manual, and the main maintenance factors as follows:

3.1.1 高压阀出现内漏

3.1.1 Inner leak of high pressure valve

关闭样水总门，待阀门温度下降至室温后，松开阀根处的压紧螺母，取下阀杆组件及密封体，观察阀杆顶端的硬质合金球和密封体，如硬质合金球出现汽蚀，此时向下按住合金球并转动改变密封面即可。如密封体出现损伤，则更换新的密封体即可。

Switch off the main valve, when the temperature of the valve goes down to the room temperature, release the pressed nut at the root of the valve, take off the spindle components and sealed body, observe the hard alloying pellet and sealed body on the top of spindle, if the hard alloying pellet come to cavitations， press down the pellet and turn to change the sealed surface. If the sealed body was broken, then change for a new one.

3.1.2 高压阀出现外漏

3.1.2 Outer leak of high pressure valve

阀芯与阀体的大螺母处出现渗水或汽蚀现象，关闭样水总门，待阀门温度下降至室温后，退出阀杆，用扳手重新拧紧大螺母，如果上述操作不解决问题，则松开阀门定位座与阀体之间的大螺母，观察密封面处的损坏
