Intelligent operation of non negative pressure variable frequency water supply equipment and pressurized equipment for domestic water supply

Description :

Non negative pressure variable frequency water supply equipmentFeatures: The non negative pressure steady flow tank has automatic control accessories such as liquid level detection, pressure detection, vacuum cleaner, etc. This device has significant energy-saving effects, does not require the construction of a water tank, does not require regular cleaning and disinfection, and has low investment costs.

　　1. Integrated design, compact structure, direct installation of the system in the water tank (reducing the construction of pump rooms if outdoors), low investment, easy installation, and beautiful appearance.

　　2. By utilizing the superposition of pipeline pressure and automatic frequency conversion operation mode, the energy-saving effect has been significantly improved (40% for large pipelines).

　　3. Easy to install, with only one municipal pipeline inlet and one water supply outlet.

　　4. Stable operation, low vibration, and low noise (noise level below 50 decibels).

　　5. The system's water supply is stable (even if the pipeline network is temporarily cut off, it can still be supplied normally through the water tank), fully ensuring the pressure at the end of the system.

　　6. Automatic inspection function can be added to reduce property management costs.

　　7. Adopting PLC programmable control for fully automatic operation, easy operation and maintenance.

　　The water from the tap water pipeline enters the steady flow compensation tank, and the air inside the tank is discharged from the vacuum suppressor. After the water is filled, the vacuum suppressor automatically shuts off. When the pressure of the tap water network can meet the water requirements, the system will supply water directly from the bypass to the system network; When the pressure of the tap water network cannot meet the water demand, the system pressure signal is fed back to the variable frequency controller through a remote pressure gauge. The water pump runs and automatically adjusts the speed and constant pressure water supply according to the amount of water used. If the running water pump reaches the power frequency speed, another water pump will start variable frequency operation. When the water pump is supplying water, if the water volume in the tap water network is greater than the flow rate of the water pump, the system will maintain normal water supply; During peak water usage, if the water volume in the tap water network is less than the flow rate of the water pump, the water in the steady flow compensator can still be supplied normally as a supplementary water source. At this time, air enters the steady flow compensator through a vacuum suppressor, damaging the vacuum environment inside the compensator and avoiding the impact of insufficient water supply on the municipal pipeline network. After the peak water usage, the system returns to normal water supply. When the water supply network is shut down, causing the liquid level of the steady flow compensator to continuously decrease, the liquid level controller will feedback the signal to the variable frequency controller, and the water pump will automatically stop to protect the water pump unit.
