What should you pay attention to when charging a small steam generator?
Note on the water supply of Xuen small steam generator:
1. When entering the water, the steam generator water pipe and the economizer should be used to remove the air first to avoid water impact.
2. Water quality: Steam boilers require the use of soft water that has been tested and tested for water.
3, water level: the water should not be too much, otherwise the water will be heated when the temperature is too high, and the drain valve should be opened to drain water, resulting in waste. Generally, the water can be stopped between the normal water level and the low water level of the water level gauge.
4, water temperature: the water supply temperature should not be too high, the water supply speed should be slow, in order to prevent the boiler from being unevenly heated and thermal stress or make the pipe expansion gap to form a gap and leak. For a steam boiler that has been cooled, the inlet water temperature does not exceed 90 ° C in summer and does not exceed 60 ° C in winter.
5. Check the water level again after about 10 minutes without water. If the water level is lowered, it may be that the drain valve or the drain valve is leaking or not closed; if the water level rises, it may be that the boiler inlet valve is leaking or the feed pump is not stopped. Factors should be identified for exclusion. During the watering period, it is necessary to strengthen the view of the manhole and hand hole cover of the drum and the header, as well as the valves, flanges and wall heads of various parts. If a leak is found, the steam generator will immediately stop the water and process it.
