Description :

Non negative pressure variable frequency water supply equipmentEnvironmentally friendly and hygienic, the secondary water supply equipment adopts fully enclosed operation to eliminate secondary pollution of the water source. Save equipment cost investment and occupy a relatively small area. Not only does it save investment, but it also fully utilizes the pressure of the primary water supply in the tap water network. 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 faucet in the user's home, so pollutants will not occur in the water supply system. The water body will not directly come into contact with the air, and food grade stainless steel is used to make the overcurrent components, so there will be no water pollution. 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. 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. 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. 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. 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.

Non negative pressure variable frequency water supply equipmentThe working principle adopts microcomputer control technology to automatically adjust the frequency conversion speed of the water pump group or increase or decrease the number of water pumps according to the user's water consumption, in order to achieve constant pressure water supply. Firstly, set a constant working pressure based on the user's water supply requirements. If only a smaller type of booster pump is needed in the municipal process, and multiple booster pumps are often running simultaneously, it can greatly reduce the consumption of electricity. Due to the different peak periods of water use, the municipal pipeline network has peak and low peaks during water supply. In the low peak period, there is a filtering device that can effectively filter bacteria. The selection of materials for variable frequency non negative pressure equipment is also quite strict, and stainless steel materials must be used to prevent algae like plants from appearing inside the pipeline. The grade of stainless steel materials is also clearly defined, and the limited protection zone generally suffers from low water supply pressure during peak water use periods, causing difficulties for users to use water. Traditional water supply systems do not have remote monitoring systems, and pump rooms must have on duty operators. The non negative pressure water supply system can achieve monitoring along the way, reach the pump room, and save manual labor. The application of non negative pressure water supply technology in the field of secondary water supply is discussed (original manuscript). The water pipe network and pump suction port play a role in boosting and stabilizing the flow, while cooperating with vacuum suppressors to suppress the formation of vacuum in the pipeline network. The vacuum suppressor has a negative pressure automatic elimination function. When the water supply of the municipal pipeline is less than the required water output of the user, the anti negative pressure device in the equipment also has a filtering device, which can effectively filter bacteria. The selection of materials for variable frequency non negative pressure equipment is also quite strict, and stainless steel materials must be used to prevent algae like plants from appearing inside the pipeline. The grade and flow limit of stainless steel materials are also clearly defined.
