Small non negative pressure water supply equipmentIt is a secondary pressurized water supply equipment that is directly connected to the municipal water supply network by a pressurized water supply unit, and is connected in series with the residual pressure of the municipal water supply network to ensure that the pressure of the municipal water supply network is not less than the set protection pressure (which can be zero pressure of relative pressure, and is called negative pressure when it is less than zero pressure).
Small non negative pressure water supply equipmentThe core is how to prevent negative pressure during the operation of the secondary pressurized water supply system, eliminate the impact of unit operation on the municipal pipeline network, and achieve safe, reliable, stable, and continuous water supply without affecting nearby users' water use.
Small non negative pressure water supply equipmentThe entire equipment consists of a steady flow tank, vacuum suppressor, variable frequency speed control water pump unit, pressure sensor, variable frequency control cabinet, backflow preventer (optional), disinfection device (optional), small flow pressure holding tank (optional), etc. The inlet pipe from the municipal pipeline network is directly connected to the inlet of the stabilizing tank, and the outlet of the stabilizing tank is connected to the inlet pipe of the booster pump group through a disinfection device. The outlet pipe of the booster unit is connected to the user's water pipe and directly supplies water to the user's pipeline network.
Advantages of Small Non Negative Pressure Water Supply Equipment
1. Save equipment cost investment and occupy a relatively small area,. Not only did it save investment, but it also fully utilized the pressure of the primary water supply in the tap water network. It is possible to reduce the selection of the pressure pump appropriately to save the cost investment of the equipment. Secondly, the system's land area is saved, and the saved land is fully utilized to further increase the occupied area of the house, meeting the requirements of China for land resource conservation.
2. Clean and pollution-free, the water supply equipment system is equipped with a fully sealed structure, from the boiling water in the tap water pipe network to the water in the user's home, so pollutants will not occur in the water supply system. The water body will not directly thicken the air, and food grade stainless steel is used to make the flow components, so there will be no water pollution.
3. The obvious energy-saving effect is usually achieved through direct series connection between the equipment and the water supply network, which means that under the condition of a water supply network pressure in the water plant, the required pressure is superimposed and appropriately increased according to the insufficient pressure, promoting the full utilization of the residual pressure in the network. During the low peak period of reusing water, it is possible to not operate the equipment, which will have a significant energy-saving effect.
4. Easy to install. Due to the fact that the non negative pressure stacked water supply equipment belongs to a complete supply system, users only need to connect the inlet and outlet water pipes to use it, with a short construction period and easy installation.
5. Lower operating costs. Due to the relatively small application in the selection process of booster pumps and the ability to use pump associated water supply methods, the primary water supply pressure of the city can be utilized during low peak periods of urban water use. The method of not starting the pump or only starting one pump can be used to meet the water demand of the city. Other pumps can only be started when the peak water usage period arrives. Therefore, there will be lower energy consumption during the operation of the equipment, which effectively reduces operating costs.
6. The occurrence of power outages will not affect the status of water supply. Due to the direct connection between the public water supply network of the equipment and the user network, even if the booster pump stops running during a power outage, the primary water supply pressure of the water plant can still meet the water demand.
7. Post management provides convenience. Due to the fact that the non negative pressure stacked water supply equipment belongs to the microcomputer fully automatic frequency conversion control, it has the effect of automatically shutting down power-off equipment and automatically starting up incoming equipment. It has relatively complete fault detection, technical diagnosis, and alarm reminders, which promotes the advantages of relatively simple equipment management and maintenance process. Secondly, as it will not be contaminated, there is no need for cleaning work.
