Non negative pressure variable frequency water supply equipment, pipeline network stacked variable frequency water supply equipment, secondary constant pressure water supply equipment

Description :

Non negative pressure variable frequency water supply equipmentAlso known as pipeline stacked water supply equipment, the energy-saving effect is quite significant. Pressure is only generated when the pressure in the water supply network is insufficient, and during periods of low water usage frequency, no pressure is generated, saving energy consumption.Non negative pressure water supply equipmentA complete set of water supply equipment does not require separate installation, only the connection of inlet and outlet is needed to achieve installation. It is precisely becauseNon negative pressure water supply equipmentIt is a stacking device, so during a power outage, it will not affect the pressure of the municipal water pipeline, nor will it affect our normal water experience, which is quite icing on the cake.

Non negative pressure variable frequency water supply equipmentCharacteristics of the system:

　　1. Without the need for water tanks or pools, water can be supplied directly through the pipeline network to prevent secondary pollution of water quality.

　　2. Adopting advanced intelligent frequency conversion control technology, automatic voltage compensation.

　　3. Unique anti negative pressure automatic control system

　　4. Automatic shutdown when water is cut off, and automatic startup when water is supplied.

　　5. When the natural pressure of the pipeline meets the water demand, it automatically enters standby mode.

　　6. Fully utilize the original pressure of tap water, downgrade the selection of booster pumps, and reduce power consumption.

　　Stacked high position regulated storage non negative pressure water supply equipment

　　1. The tap water booster pump station and non negative pressure water supply equipment use intelligent control technology and voltage stabilization compensation technology to ensure that the equipment does not generate negative pressure on the municipal pipeline network, ensuring uninterrupted water supply to the user pipeline network. The flow controller used in the equipment can automatically adjust the input water volume from the municipal pipeline network to the equipment while maintaining the service pressure, ensuring that the municipal pipeline network does not generate negative pressure. During peak water usage periods, the energy storage device releases a certain pressure of nitrogen gas pre filled to ensure that the water in the high-pressure chamber of the stabilizing compensation tank is compensated to the constant pressure chamber with a certain pressure, which can supplement the insufficient water supply of the municipal pipeline network within a certain period of time. Through a bidirectional compensator, the stabilizing compensation tank can store energy during low water usage periods, playing a stabilizing compensation role in the user pipeline. At night and during low flow water supply, water can be supplied through a small expansion tank to prevent frequent pump start-up. Fully utilizing the pressure of the municipal pipeline network, the energy-saving effect is significant. If the water pump is directly connected to the municipal pipeline network, there is no need to build a reservoir, it can be directly connected to the municipal pipeline network. However, according to the urban water supply regulations in China, in order to prevent any impact on the water use of surrounding residents, it is not allowed to install domestic or production water pumps directly on the municipal pipeline network. In order to solve the problem of water supply equipment being able to be connected in series with the municipal water supply network without generating negative pressure, and without affecting the water use of other users, it is necessary to install a non negative pressure flow controller, a segmented pressure stabilizing compensation tank, a bidirectional compensator, etc. between the pump inlet and the municipal water supply network. The non negative pressure flow controller constantly monitors the pressure of the municipal water supply network, ensuring that the municipal water supply network does not generate negative pressure while also fully utilizing the existing pressure of the municipal water supply network.

　　2. No negative pressure flow controller, which constantly monitors and controls the pressure in the municipal pipeline network and compensation tank. When the tap water pressure is insufficient, the no negative pressure controller starts working to ensure that the water pressure in the municipal pipeline network is not affected. This not only ensures the safety and stability of user water use, but also ensures the stability of municipal pipeline network pressure.

　　3. Bidirectional compensation device, energy storage and release regulation device. Bidirectional compensation can automatically compensate for continuous water flow in the tap water pipeline network, and also play a stabilizing role in the user pipeline network, ensuring that the equipment does not generate negative pressure on the tap water pipeline network. During the low peak period of water supply, the bidirectional compensator starts to work, directing the high-pressure water at the outlet of the water pump to the high-pressure chamber to continue replenishing water. As the liquid level gradually rises, the pressurized nitrogen gas is squeezed back into the energy storage device, completing the process of replenishing water in the tank during the low peak period. When the water supply or municipal pipeline pressure drops during the peak period, the energy storage device releases energy, squeezes the high-pressure chamber water to supplement the constant pressure chamber, and together with the municipal water in the constant pressure chamber, replenishes water to the user. This completes the process of replenishing water to the user during the peak period.

　　4. Energy storage device, which contains pre pressurized nitrogen gas that is insoluble in water. During peak water supply periods, it releases energy to squeeze high-pressure chamber water and replenish it to the constant pressure chamber pipeline network. By fully utilizing the principle of energy conservation, it can provide users with water replenishment during peak periods, ensuring that the water in the tank can compensate to the user's pipeline network to a certain extent, suppressing negative pressure, and ensuring that it does not affect the municipal pipeline network.
