Twenty seven floors of secondary water supply on that floor

Secondary water supply for high-rise buildings starts from several floors:

1. The municipal water supply pressure can generally only be supplied to 7 floors below (in fact, 7 floors are also under secondary pressurization) can not reach the water supply pressure of high-rise buildings, so only water supply equipment can be installed to improve the water supply pressure to send water to high-rise buildings, and this pressurized equipment is the secondary water supply equipment. High-rise residential buildings need more secondary water supply, what is secondary water supply? Before figuring this out, let's take a look at what a high-rise residential is.

2. Generally speaking, 7-storey residences with eaves height of more than 20 meters can be called high-rise residences, and according to the different heights of buildings, high-rise residences can be divided into small high-rises, high-rise buildings and super high-rises. Usually people call 7-9 storey buildings as medium and high-rise (that is, people usually say "small high-rise and above are high-rise, and the total height of more than 100 meters is super high-rise. At present, in Huai'an, small high-rise and high-rise are the more common high-rise residences.

3. The water supply equipment is a water supply device that automatically starts and stops with a certain flow rate and head per unit time. According to the use, it is divided into four categories: fire protection, life, production, and sewage treatment. At present, the most widely used secondary water supply equipment includes non-negative pressure water supply equipment, frequency conversion constant pressure equipment, box-type non-negative pressure water supply equipment, etc.

The water source to the waterworks is called primary water supply, and the waterworks to the community users are called secondary water supply. What you are asking means is that a booster pump has been added in the middle. Just ask about the property.

Standard for the pressure of the secondary water supply in the upper floor:

1. One floor (bungalow), two floors plus, three floors to six floors plus each floor, so the municipal government ensures that the six floors have qualified water, then the pressure is.

The pressure of one kilogram of rice and the pressure of tap water delivery are 2-4 kilograms, that is, the secondary water supply must be provided above 40 meters, and the secondary water supply should be set above 30 meters considering the normal water pressure.

Secondary water supply equipment, generally located on the ground or in the basement. Units with tap water can use this equipment to dispatch peak water consumption, increase water pressure, and meet the needs of large areas and high floors during peak water consumption. Units, factories or villages that do not have running water only need to connect the equipment to the water source power supply to get a stable water pressure to meet the water demand.

The secondary water supply equipment is composed of three parts: air pressure tank, water pump and electronic control system, and its outstanding benefits are that there is no need to build a water tower, the investment is small, the area is small, the organization is active, and the completion and operation are fast.

The automatic dispatch of water and gas, automatic operation, energy saving and automatic grid connection of tap water are selected, and the water can still be supplied after power failure, and there is no need to guard after commissioning. It is widely used in the production, daily and operational water supply of enterprise units, vertical towerless water supply residential areas and villages. It is suitable for places with water supply households within 5,000 households, daily water supply within 3,000m3, and water supply height of more than 100 meters.

The secondary water supply equipment adopts pneumatic water supply. The sealed tank is used, and the high-pressure air and water pressure in the tank is used to achieve the purpose of water supply. The specific operation is to press the water into the tank through the check valve by the water pump, so that the gas in the tank is contracted, and the pressure gradually increases.

When the pressure reaches the specified upper limit, the electric contact pressure gauge automatically connects the pump through the control cabinet.

The water pressure in the equipment is higher than the pressure of the external pipe network, and the water is automatically sent to the water supply network. When the water level in the tank drops, and the gas expansion pressure in the variable frequency constant pressure water supply tank decreases to the specified lower limit direction, the electric contact pressure gauge restarts the pump through the control cabinet. And so repeatedly, so that the equipment is constantly supplied with water.

When there is a shortage of gas in the tank, the make-up valve can automatically replenish the gas.

Summary. Hello! We will be happy to answer for you: the secondary water supply for the 17th floor is located in the basement or on the 6th and 7th floors. The secondary water supply is to increase the water pressure so that the water pressure on the upper floors is enough.

Hello! We are glad to answer for you: the secondary water supply equipment on the 17th floor is still destroyed in the underground closed room or on the 6th-7th floor. The secondary water supply is to increase the water pressure so that the water pressure on the upper floors is enough.

Usually on the 7th floor, because the general municipal drainage pressure can only maintain 6 floors to build the water under the field, once it is higher than the 6th floor, it is necessary to carry out secondary pressurized water supply. But it depends on the region and the terrain. If the terrain is high and the municipal water pressure cannot be reached, some high-rise buildings may shout from the 4th floor to set up secondary water supply equipment.

The secondary water supply of the community is actually a pressurized system for the water pressure of the high-rise residents in the community. This system is cumbersome to install, and is mainly used for installation when the high-rise is not under insufficient pressure. However, although the secondary water supply makes the water supply of high-rise users in Xunjiaochang more convenient, it is necessary to pay attention to the water source of the secondary water supply that is easy to pollute.

The secondary pressurized water supply on the 26th floor starts from the 4th or 7th floor, and all the water bills will be more expensive due to the additional water supply input, while the municipal water supply is only responsible for the 1-6th floor. Generally speaking, municipal direct water supply is used below 4-6 floors, and automatic secondary water supply equipment must be used for the above parts.

However, there are also pressurization equipment directly used from the first floor, depending on how much the local municipal pressure is, and the water supply pressure of the water company can only reach about 6 floors according to the relevant regulations, which is far from meeting the needs of the high-rise.

The national family standard six-story building needs to meet the 28m service head, and the other is according to the Ministry of Construction's specifications, the three-story building is 14m head, and the local water plant water supply is less than 28m head according to the 14m head.

Roof. "The secondary water supply equipment on the 32nd floor is generally on the roof of the building, and water is transported down from the top floor to ensure that the owners have water. "Secondary water supply" refers to the use of storage or pressurization facilities to store and pressurize urban public water supply or self-built facilities, and then supply water to users.

Secondary water supply is an essential equipment for high-level water supply.
