In order to keep the hot water boiler running safely, the precautions for sewage discharge are as follows:
In addition, the hot water boiler also has a leakage protection mechanism. When a short circuit and electrical leakage occur, its power will be automatically cut off to avoid fire.
1. Before sewage discharge, the water level in the boiler should be adjusted to a level slightly higher than the normal water level. There should be no sound of flow in the sewage pipe. Touch the sewage pipe outside the sewage valve with your hand. If you feel a high temperature, it means that the sewage valve is leaking. You should check it in time, find out the cause, and then solve it.
2. The sewage discharge of the hot water boiler itself needs to be discharged regularly and evenly. At least once per shift. On a boiler, there are multiple sewage pipes at the same time. Each sewage pipe is discharged in turn. If only part of the sewage pipe is discharged, and the other part is not discharged, it will cause some sewage pipes to be blocked, which will cause water circulation damage. In serious cases, pipe burst accidents will occur. When multiple boilers use the same main sewage pipe at the same time, and there is no check valve on the sewage pipe of each boiler, it is strictly prohibited to discharge sewage at the same time to prevent sewage from flowing back into other boilers.
3. When discharging sewage, it should be done after the hot water boiler is compressed or when the load is low, because the water circulation in the boiler is relatively slow at this time, the dirt in the pipe is easy to accumulate, the sewage discharge effect will be better, and it will not affect the boiler output.
4. The sewage discharge operation in the boiler should be carried out in a short state, that is, the time interval between each sewage discharge is short and repeated many times, which is conducive to the return of dirt to the sewage outlet, so that it can be discharged in a concentrated manner.
5. During the sewage discharge work of the hot water boiler, always pay attention to the changes in the water level to avoid water shortage in the boiler due to sewage discharge work. Relevant responsible personnel are prohibited from leaving the site.
