Possible causes and solutions:
1, the inlet pipeline of the water pump is too small, or the pipeline resistance is too large (the inner wall is not clean and there are too many turns); Or the diameter of the outlet pipe section is too large.
2, there is air in the water, the pump installation position is not correct, or the installation position is too high.
3. If it is a metal pipe, fixing devices should be installed on the front and rear outlet pipes of the pump. If it is a plastic pipe, then the pump body itself should be fixed.
There is a vent hole at the top of the furnace body, so the boiler is in a pressure-free state and there is no explosion danger. At the same time, the whole machine is equipped with overheating protection (when the water temperature in the boiler is too high, the heating pipe will automatically stop working and give a buzzer alarm), secondary overheating protection (when the temperature of the boiler shell exceeds 105℃, the secondary circuit will be automatically cut off) and water shortage protection (when the boiler water is lower than the extremely low water level, the boiler will stop working and give a buzzer alarm).
Extended data:
In the horizontal coal-fired boiler, after the fuel is burned on the grate, the flame passes through the low wall to the burnout chamber, from the burnout chamber to the front smoke box through two side flues, and then from the smoke tube bundle to the back smoke chamber, and then is pumped out by the induced draft fan and discharged into the atmosphere through the chimney, which not only prevents the bottom of the boiler shell from being irradiated by the high temperature of the furnace.
But also can reduce the temperature of the flue gas at the entrance of the high-temperature tube sheet, and with the aid of backwater injection, there is no dead water area at the bottom of the drum, which can effectively prevent the tube sheet from scaling and the bottom from bulging due to supercooling and boiling, and the flue gas can be turned to the smoke chamber for dust removal, thus reducing the original dust concentration. ?
Vertical coal-fired atmospheric hot water boiler, the heating zone pipes are all straight pipes, and there are enough hand hole cleaning devices to facilitate manual and mechanical cleaning of dirt and internal inspection. The horizontal coal-fired atmospheric hot water boiler is equipped with a manhole large enough for people to enter the furnace body, which greatly facilitates the inspection and maintenance of the boiler.
