If you know the rated working pressure of the hot water boiler, how to determine the setting pressure range of the safety valve? If a hot water boiler knows its rated working pressure, then it is possible to determine the setting pressure range of the safety valve, which is 1.1 times the working pressure on the lower limit of the pressure value, but not less than the working pressure plus 0.07MPa. In the upper limit of the pressure range, it is 1.2 times the working pressure, but not less than the working pressure plus 0.1 MPA.
Hot water boiler heating briefly describe briefly heating hot water boilers. Hot water boiler control effect and its importance in the regulation of the heating system, and according to weather conditions and the heating zone is not the same characteristics presented can be applied to different conditions of chain-type hot water boiler control plan. Discuss the handling difficulties of Chain boilers, it gives way to one kind of set the water temperature of the boiler, made applicable to the time lag, PID neural network model with speculation nonlinear system control, and apply it in a boiler burning system to ensure safe and economic operation of the hot water boiler. These are the introduction of hot water boiler heating system.
For more than two decades, it has been the focus on clean boilers, the insistence on precision and wisdom, and the pursuit of exquisite craftsmanship that have made today's Fangkuai boilers. Fangkui Boiler will always be based on the boiler industry, and will return customer support and trust with brilliant results and sophisticated technology.
Steam pressure reduction is the lowering of the steam pressure at the boiler plant by means of the pressure setting on the boiler plant master control. Steam pressure reduction affects mainly the high pressure part of the steam system.Get a Quote
