What is secondary water supply and what is secondary pressurized water supply system? How many ways of pressurized water supply does the hotel have? What should I check for the second water supply inspection? & gt What is a secondary pressurized water supply system? How many pressurized water supply modes does the hotel have? What should I check for the second water supply inspection? >; & gt Secondary pressurized water supply >:> It means that besides relying on gravity, water pressure is increased by air pressure and other methods to send water to a higher water level, which can break the traditional mode of high water tower and directly supply water from low places to high places. The secondary pressurized water supply is mainly to raise the water in the pipeline to the actual height of the building under the environment of insufficient municipal water supply pressure. & gt& gt In general municipal water supply, the pressure reaches six floors, but above six floors, it is necessary to increase secondary water supply equipment according to relevant state regulations. Generally speaking, the municipal water supply "tap water" is stored in a container, and then the water is knocked down to a higher height with a pump of corresponding power "on demand" to meet the needs of more than six floors. & gt& gt It is very important to check the secondary water supply. Generally speaking, the inspection contents include: water tank, water level, water pump, power control box, automatic control valve and pipeline. & gt& gt Secondary pressurization refers to the process of increasing the flow or pressure of medium through power machinery such as water pump. The hotel pressurization method is the same as the conventional water supply pressurization method at present, and some outdated secondary pressurization methods have been basically eliminated. There are three popular types: negative pressure type, pneumatic tank type and water tank frequency conversion type, as well as Qingdao Lisan Group and other well-known domestic enterprises.
