Ask what method of secondary water supply is used in the newly built high rise buildings

The water supply mode of the high-rise generally adopts secondary water supply.

Frequency conversion constant pressure water supply equipment is our company using international advanced frequency conversion technology, the introduction of the United States or Japan microcomputer control, through the pressure sensor, according to the change of water consumption, automatic control of multiple pumps frequency conversion cycle soft start, because of its advanced technology, complete performance and high reliability and high quality and leap to become the preferred product for production and domestic water supply equipment.

Product features: 1. Electricity and water saving, less land occupation, fast installation, easy maintenance, etc., which can realize a variety of working conditions such as constant voltage variable and variable voltage variable.

2. High degree of automation, convenient management, long service life, with various automatic protection functions such as phase loss, undervoltage, overvoltage, overcurrent, overload, short circuit, overheating, stall and so on.

Working principle: This product detects the pressure of the pipe network through the pressure sensor and turns it into an electrical signal and sends it to the programmable controller or microcomputer controller, and after analysis and processing, the signal is transmitted to the frequency converter to control the speed of the water pump.

When the water consumption increases, the pressure of the pipe network decreases, the frequency of the pump motor increases, the pump speed becomes faster, and the water output increases; When the water consumption is reduced, the pump speed is slowed down, and the water output is reduced so that the pressure of the pipe network can be maintained at the set pressure value.

When multiple pumps are running, the machine by machine soft-starts, from frequency conversion to power frequency until the pressure flow is satisfied, and the circulation control of the pump is realized.

The pressure gauge used in this product is a remote pressure gauge, which sets a certain value, and controls the increase and decrease of the pump frequency by floating up and down the pointer to achieve the constant pressure of the system.

Generally, the secondary water supply equipment of pipe network superposition is adopted, and now the high-rise water supply in cities and towns is pressurized twice, and in order to avoid the pollution of water tank pools, pipe network superimposed equipment is used, that is, secondary water supply equipment.

Under normal circumstances, the secondary water supply equipment is installed in the equipment room in the basement of the community. If there is no basement in the community, the secondary water supply equipment is generally installed in the equipment room on the first floor of the community.

Secondary water supply refers to the storage of municipal tap water by units or individuals through self-built storage tanks or stainless steel water tanks, and then pressurized by secondary water supply equipment or flowing to every household in the upper floor through natural drops. Compared with municipal direct water supply, the water quality of secondary water supply is more likely to be polluted, and safety and reliability have always been valued by the public.

Normally, the pressure of the municipal water supply does not reach more than 7 floors, so most of the secondary water supply starts from the 7th floor.

The upper floor is supplied with water from the seventh floor.

du began in our country.

ZHI stipulates that the water supply of six floors is guaranteed, and the capacity pressure of the DAO municipal water distribution (tap internal water) pipe network is only guaranteed below six floors, and the secondary pressurized water supply is required for more than seven floors (including seven floors).

With the technological progress of housing construction, the proportion of high-rise residential buildings continues to rise, so the current high-rise residential areas generally need secondary water supply because they are too high.

China's "Outdoor Water Supply Design Code" GB50013-2006 stipulates that the water supply of six floors is guaranteed, that is to say, the pressure of the municipal water distribution (tap water) pipe network is only guaranteed to be less than six floors (including six floors), then more than seven floors (including seven floors) must be pressurized for water supply.

Generally, the secondary water supply on the high copy floor starts from the seventh floor

Generally, the pressure of the pipe network of the municipal government drainage can only be used below 6 floors. Once the high DAO passes through the 6th and 7th floors, it needs to be pressurized for a second time. In fact, with the technological progress of housing construction, the proportion of high-rise residential buildings is also rising, so your current high-rise building community will generally use secondary water supply.

The pressure of urban pipe network water supply can generally provide normal water supply for residential buildings with seven floors and below, and high-rise residential buildings with eight floors and above need to supply the urban pipe network water supply to residents in the community after secondary pressurization, also known as secondary water supply. If it is a super high-rise building, the water supply is generally carried out from the 5th floor.

Generally, above the seventh floor, below can directly use the municipal pipeline water pressure.

Yes, but according to your own contract and pressurization situation, generally small high-rise 6th floor below do not need to pay the secondary pressurized water fee.

The secondary water supply equipment starts from the several layers of water supply pipes that are connected at the beginning, and it is counted from several layers, usually 5 or 6 layers. Tap water refers to the water produced by the tap water treatment plant after purification and disinfection that meets the corresponding standards for people's life and production.

The pressurization equipment used in each community of high-rise residential buildings may be different, and the energy consumption is not the same, and the property is apportioned according to the cost of pressurization in the community, and appropriate charges are also allowed. It's just that before the specific charge, the owner or the construction unit and the property service company agree in the property service contract that it should be publicized to the owner after the determination of **.

Pay attention to water charges

The water tariff between the owner and the water company shall be priced according to the standard of tap water used by ordinary residents**; The property service company is "entrusted", and generally this kind of "entrusted", the property service company is silent and takes the initiative to "do it for the owner" and pay the water bill on behalf of the owner.

The daily operation and maintenance costs of the common parts of the property and the common facilities and equipment", and the "secondary pressurization fee" should actually belong to the category of "daily operation expenses of the common facilities and equipment" of the owner, so the "secondary pressurization fee" has been included in the property service fee paid by the owner to the property management service company.

Abstract Dear, Hello! Glad to serve you! The high-rise buildings are all two-dimensional secondary water supply.

Because in this way, it can ensure that residents can use water normally, generally from the 6th floor for secondary water supply, and in some places, the secondary water supply is carried out from the 7th floor, when the water is transmitted, and it must be pressurized after being sent to the secondary ** equipment.

Continue to upload to the top floor to ensure that the residents on the top floor can also use the water normally.

Is the water supply of high-rise buildings secondary on all floors?

Hello dear! Glad to serve you! The high-rise buildings are all two-dimensional secondary water supply.

Because in this way, it can ensure that residents can use water normally, generally from the 6th floor for secondary water supply, and in some places, the secondary water supply is carried out from the 7th floor, when the water is transmitted, and it must be pressurized after being sent to the secondary ** equipment. Continue to upload to the top floor to ensure that the residents on the top floor can also use the water normally.

That is to say, the water supply below the 6th floor is a direct water supply, yes, pro.
