What are the correct inspections of steam boilers?
The correct way to use the steam boiler is to check it. Someone may ask, how should the boiler be properly inspected? What are the inspection steps?
1. Check the discharge valve, discharge pipe and safety valve of the steam boiler, for example, if there is any blockage in the discharge pipe, if it is blocked, it must be cleaned in time. Is there any abnormality in the switch of the blowdown valve, is it flexible enough, does the lining in the packing cover leave enough room for adjustment, and the sewage pipe is smooth.
Second, to check the pressure gauge and water level gauge of the steam boiler, mainly to observe whether the abnormality is displayed on the water level table, and whether the entire state of the drain valve in the column above the water level gauge is correct, and secondly, it seems that the pressure gauge is not Within the time limit, the prescribed inspection mark is not intact. There are also other abnormalities, such as whether the pipe is bent or the connection of the connecting pipe is firm, and whether the middle valve is abnormal when it is switched.
3. After the end of the water pressure test, adjust the steam boiler to full water, then open the steam boiler to know that steam is present, but make sure that the air valve is open. Because the steam boiler will use scale after a period of use, if the phenomenon of scaling occurs, it will definitely affect the temperature increase effect of the steam boiler wall, and the furnace with too much scale will be too high. Collapse, so the scale in the steam boiler must be cleaned up in time.
