From what floor does the small high-rise floor of 18 start to collect secondary pressurized water charges?

Generally speaking 18-story residential building 1- 10-story low-level water supply1-18-story high-level water supply secondary booster pump or negative pressure water supply equipment should consult 10-story pipe-well property.

1. Secondary pressurized water supply: Secondary pressurized water supply refers to raising the water pressure to a higher water level with the help of air pressure outside gravity, which can break the traditional high water tower mode and directly supply water from a lower part to a higher part.

2. Basic concept: Secondary pressurized water supply refers to raising the water pressure to a higher water level with the help of air pressure outside gravity, which can break the traditional high water tower mode and directly supply water from a lower place to a higher place.

Three. Form of expression:

1. Steady-flow compensator control: When the water supply of the municipal pipe network is insufficient or the water consumption of users is greater than the supply capacity of the municipal pipe network, the vacuum suppressor of Boyong water supply is turned on, and air enters the steady-flow compensator, so that the originally closed compensator becomes a cut-off water tank to suppress negative pressure. In addition, the steady flow compensator is equipped with liquid level control, when it is lower than the low liquid level, the water pump stops working.

2. Self-control current limiting mode: when the water supply of municipal pipe network is insufficient or the water consumption of users is greater than the supply capacity of municipal pipe network, the frequency converter is limited through the feedback of pressure sensing signals, so that the water pump does not take excessive water. When the water supply of municipal pipe network meets the requirements, the system returns to normal.

3. Pressure control point mode: When the water supply of municipal pipe network is insufficient or the water consumption of users is greater than the supply capacity of municipal pipe network, directly start the variable flow and constant pressure water supply pump, and the system will return to normal after the water supply meets the requirements.

Four. Applicability: If the height of public buildings exceeds12m and residential buildings exceed 6 floors, secondary water supply facilities must be designed and constructed; Commercial and residential buildings with mixed floors and above are regarded as public buildings.
