Fully automatic constant pressure water replenishment device, intelligent constant pressure stabilizing closed cycle system dedicated

Description :

  The fully automatic constant pressure water replenishment device is a pressure maintenance and water replenishment equipment used in closed water circulation systems, mainly to solve the problems of system pressure fluctuations and water shortage caused by water temperature changes or leaks. This device monitors the pressure of the system pipeline network in real-time through high-precision pressure sensors. When the pressure is below the set lower limit, it automatically starts the water replenishment pump to replenish water. When the pressure reaches the set upper limit, it automatically stops, ensuring that the air conditioning, heating or industrial cooling system is always in the optimal working pressure state, preventing cavitation, vacuum damage or overpressure pipe bursting, and ensuring the safe and stable operation of the system.

  The fully automatic constant pressure water replenishment device usually consists of core components such as diaphragm pressure tank, variable frequency water replenishment pump, pressure sensor, intelligent control cabinet, and safety valve. The implementation standards refer to relevant industry standards such as GB/T 50366 "Technical Specification for Ground Source Heat Pump System Engineering" and JB/T 10525 "Fully Automatic Pneumatic Water Supply Equipment". The typical working pressure range covers 0.6MPa to 1.6MPa, and higher pressure levels can be customized according to actual needs. The control accuracy is usually controlled within ± 0.01MPa, with multiple safety functions such as overload protection, phase loss protection, and waterless shutdown. The electrical components are selected from internationally renowned brands to ensure long-term reliability and stability.

  When selecting a fully automatic constant pressure water replenishment device, it is important to consider the total water capacity of the system, maximum operating temperature, static pressure height, and allowable pressure fluctuation range. Suitable for closed cycle scenarios such as high-rise building HVAC systems, central heating pipelines, industrial circulating cooling water systems, etc. If the system is supplied with water from an open water tank or does not require constant pressure maintenance, this device is not applicable. Compared with traditional expansion water tanks, the fully automatic constant pressure water replenishment device has a small footprint, flexible installation, and high degree of automation. It can effectively isolate air from entering the system, reduce the risk of pipeline corrosion, and is the preferred supporting equipment for modern building energy-saving renovation and new construction projects.

  When installing a fully automatic constant pressure water replenishment device, it should be placed in the system return pipe near the heat source or the inlet of the circulation pump to ensure that the pipeline connection is firm and leak free. Daily maintenance recommendations include checking the pre filled pressure of the pressure tank once a month to ensure it meets the system's static pressure requirements, regularly checking the accuracy of the pressure gauge readings, and cleaning the inlet filter to prevent blockages. Common faults include frequent start stop, usually caused by the rupture of the airbag in the air pressure tank or insufficient pre inflation pressure, requiring timely replacement of the airbag or re inflation; If the water replenishment pump cannot be started, check the power wiring and control cabinet signal feedback. Regular inspections can extend the service life of equipment and ensure continuous and efficient voltage regulation.
