In the steam boilers we use daily, the water level gauge is one of the very inconspicuous but very important parts. In order to maintain a good use effect, it needs to be cleaned regularly to avoid the water level caused by the accumulation of scale. A false water level appears on the meter.

    When cleaning the water level gauge in the steam boiler, first open the drain valve and flush all pipes with water to avoid any omissions; then close the valve of the water connecting pipe to ensure that the steam connecting pipe and the water level gauge are exposed to steam. rinse.

    The next thing to do is to open the valve of the water connecting pipe and close the valve of the steam connecting pipe to ensure that the water connecting pipe is properly flushed.After the completion, the steam connecting pipe valve of the steam boiler should be opened again, and then the drain valve should be closed. After the flushing work is completed, the normal operation of the water level gauge should be restored.

    In many cases, the steam boiler needs to be idled out of use. At this time, the boiler should be treated accordingly to ensure that the boiler can still maintain good working condition when it is used again.The treatment of the steam boiler is mainly determined according to the length of time it stops operating.

    If the steam boiler will be idle for a long time, reaching a deterioration of more than ten days, the gas phase protection method can be adopted for it, which can protect the boiler for a long time without rust or damage and reduce unnecessary losses. .

    However, if the steam boiler is only shut down for a short period of time, the method of maintaining the boiler pressure can be used to keep the pressure in the steam boiler stable through appropriate means so that it can enter the state as soon as possible in the later period.
