Does the current secondary water supply equipment need to install a water tank?
In the early days, the water supply was all water tanks made of cement and covered with boxes. During the inspection, it was found that the water in some water tanks was not very clean due to the defects of the box cover. However, since the 1990s, this way of supplying water with roof water tanks has been gradually eliminated.
On the one hand, it is difficult to manage the water tank on the roof, which is easy to produce secondary pollution. On the other hand, in hot summer, the temperature of the roof is high, and the residual chlorine in the water volatilizes quickly, and sometimes the microorganisms in the water tank will exceed the standard.
High-rise residential buildings no longer use water tanks for water supply.
In recent years, there are more and more high-rise buildings in various communities. The water plants on the higher floors of these communities cannot supply water directly, and they must be pressurized twice before they can be supplied to the high-rise residents. Therefore, non-negative pressure variable frequency water supply equipment is adopted for secondary water supply.
"This kind of equipment, without a water tank, actually makes full use of the original pressure in the water supply network and supplies water to the top through continuous relay pressurization. Simply put, it is basically that the water pressure is first pressed to one floor, then from here to a higher floor, and so on. There is no need for water storage conversion in the middle, so this method is called secondary water supply, but it is basically the same as direct water supply. "
