Features of variable frequency constant pressure water supply equipment:

Variable frequency constant pressure water supply equipment uses the water pressure

 at the pump outlet as a set parameter. A microcomputer automatically controls the output

 frequency of the frequency converter to adjust the pump motor speed, achieving closed-loop 

regulation of the user's water network pressure. This ensures the water supply system 

automatically maintains a constant pressure at the set value: when water consumption increases,

 the frequency increases, and the pump speed increases; when water consumption decreases, 

the frequency decreases, and the pump speed decreases. This guarantees sufficient water pressure

 and volume throughout the entire user's water network at all times.

According to user requirements, the water supply pressure value is first set, and then the power is 

turned on. The pressure sensor monitors the pipeline pressure and converts it into an electrical signal,

 which is sent to the programmable controller or microcomputer controller. After analysis and processing,

 the signal is transmitted to the frequency converter to control the operation of the water pump. When the 

water consumption increases, the output voltage and frequency increase, the water pump speed increases, 

and the water output increases. When the water consumption decreases, the water pump speed decreases, 

reducing the water output, so that the pipeline pressure is maintained at the set pressure value. When multiple

 pumps are running, each pump is soft-started, switching from frequency converter to fixed frequency until the 

pressure and flow are satisfied, realizing the cyclic control of the water pump. When the flow rate is low at night, 

the operation can be maintained by the frequency converter water pump. The frequency converter water pump

 can be stopped to maintain pressure.

Features of Variable Frequency Constant Pressure Water Supply Equipment:

① Solves low water pressure problems: Utilizing constant pressure variable frequency water supply ensures a 

constant water pressure throughout the building.

② Avoids water pollution caused by rooftop water tanks.

③ Reduces building costs, increases space utilization, simplifies structure, and lowers costs.

④ Saves energy: Saves over 30% more energy than conventional water supply equipment.

⑤ Intelligent computer control: Dedicated, independently developed system with diverse functions, providing a high level of control.

Precautions:

Install unions and ball valves for the inlet and outlet piping of the water pump for easy maintenance.

Prevent glue, Teflon tape, and other foreign objects from entering the pipes during installation.

Purge air from the water pump after installation.

Confirm that the input power supply matches the system power supply.
