The working principle diagram of the non-negative pressure water supply equipment: The constant-flow tank-type non-negative pressure water supply equipment is directly connected to the municipal water supply network and supplies water by series superimposed pressure on the basis of the remaining pressure of the municipal water supply network.
(1Variable frequency constant pressure water supply: When the water supply volume of the municipal water network is greater than the water consumption of users, the constant flow tank type non-negative pressure water supply equipment provides variable frequency constant pressure water supply. At this time, a certain amount of pressurized water is stored in the constant flow tank.
(2Negative pressure: When the water consumption of users increases, causing the pressure at the connection between the municipal pipeline network and the steady flow tank to drop, and the pressure drops to the relative pressure0When the pressure drops below, a negative pressure is formed in the steady flow tank, the intake valve of the vacuum suppressor opens, and the atmosphere enters the steady flow tank. At this point, the steady flow tank is equivalent to an open water tank with a free liquid surface, and the pressure is the same as that of the atmosphere, with a negative pressure. When the water level drops to the set value, the liquid level controller transmits the control signal to the control system in the frequency conversion control cabinet, controlling the pressurizing unit to stop working and the user to stop water supply. When the water consumption of the user decreases, the water level in the steady flow tank rises, and the gas is discharged from the exhaust valve of the vacuum suppressor. After the pressure returns to normal, the pressurizing unit automatically starts again and resumes water supply.
(3Water cut-off and shutdown function: When the municipal water supply network is cut off, the pressurizing unit will automatically stop running under the control of the liquid level controller. After the municipal water supply network resumes water supply, it will automatically start up and resume normal water supply.
(4Low-flow sleep function: When the user does not use water or the water consumption is very small, the equipment automatically enters a sleep state (shuts down) and maintains the water supply pressure. When the user resumes water use, the system automatically wakes up and resumes normal water supply.
(5When there is a power outage in the community, the municipal water supply network will continue to supply water to users in the lower areas, ensuring that water supply does not stop even during the power outage. After the power supply to the equipment is restored, it will automatically start up and resume normal water supply.
Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.
The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.
Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
