Upgrade of secondary water supply equipment to make the old district energy-saving renovation perfect

In order to eliminate the hidden dangers of secondary water supply, the country began to upgrade and upgrade the old water supply network of 14 communities from this year. The reason for the transformation began with the “age service network” overage “service” affecting the lives of residents. Since last year, the relevant departments of the water company have received more than 10 communities since they received complaints about the quality of tap water. Residents told reporters that "there will always be some reddish brown water after opening the faucet in the morning. There will be rust-like things on the filter at home. Our community was built earlier, the water supply pipeline is also older, and many water supply pipes have already Aging corrosion." According to the reporter's investigation, as time goes by, many areas of the groundwater supply network have been corroded to varying degrees, especially the numerous cast iron and iron-plated pipes laid in the 70s and 80s of the last century. As the city grows up, The "old age pipe network" has brought great inconvenience to the people's lives.

In order to better serve the people, for the energy-saving transformation, the country has invested 545 million yuan this year to renovate the old water supply network of 14 communities and upgrade the secondary water supply equipment. Up to now, the pipe network upgrade of 14 old districts in Jinan has been completed. At present, the most important thing is to transform the reception of 100 secondary water supply equipment.

It is understood that the transformation of the secondary water supply system is an urgent problem to be solved in many old residential areas. In addition to Jinan, many cities have not only modified the old pipe network of the community, but also upgraded the secondary water supply equipment. . At present, the secondary water supply equipment uses more non-negative pressure water supply equipment. The original old water supply equipment operates on the principle that tap water is introduced into the high-rise water tank through the water pump and then delivered to each household. Such manual pumping not only wastes electricity, but also has hidden dangers of water pollution.

Therefore, the technology of non-negative pressure water supply equipment has been favored by the market in the 21st century. In recent years, many districts have adopted energy-saving renovation without negative pressure water supply equipment, using municipal pipe network as water source to form a continuous closed relay pressurization. The water supply method completely avoids the water quality standard caused by the traditional 2 times pressurized water supply system and various water source pollution problems, completely maintains the water quality standard of the municipal water source, fully utilizes the pressure heat energy of the municipal water source itself, and how much to make up, effectively and effectively, Maximize the energy-saving effect of frequency conversion speed regulation.

After the renovation of the old pipe network, the community will soon be ushered in the upgrade of the secondary water supply equipment. It is hoped that the new technology of secondary water supply equipment without negative pressure can get positive feedback from the market, reduce energy expenditure, and really promote the development of energy conservation. Let the old district energy-saving renovation perfect ending.
