The Bladder-type Constant Pressure Automatic Water Supply System is one of the more advanced water supply devices in China. Its features include: it can replace rooftop water tanks, water towers, and old-style air bladders. The tank is lined with non-toxic rubber, with water inside the bladder and air outside, ensuring that water and air do not come into contact, thereby guaranteeing water quality from contamination. The tank has excellent sealing performance, allowing for long-term use with a single inflation. It occupies a small area, requires minimal investment, and the complete set of equipment is easy to install and construct, with convenient operation, management, and maintenance.

   Due to the compressed nitrogen squeezing water around the rubber inside the tank, this water is known as pressure water. Once the entire unit is assembled, it can operate. Initially, the water pump is activated to fill the water supply network and the water chamber of the pressure water tank. Part of the water is sent to the network for user consumption, while the excess water is compressed inside. When the pressure reaches the set level, the pressure controller sends a signal to the electrical control cabinet, which stops the pump. As the internal water usage decreases, the water pressure gradually drops. When the pressure falls to the set level, the pressure controller sends a control signal, and the electrical control cabinet automatically starts the pump to replenish water, sending it back to the network and the water chamber.

Performance Features:

1Efficient Space Utilization

   Portable landing expansion water tanks expand using a bladder expansion system, with only the effective volume of the tank being utilized, which is merely a fraction of the tank's total volume.30-40The tank is relatively large, and the surge pressure regulating unit adopts special technical measures to separate the expansion section and the pressure-regulating section. This allows the majority of the expansion volume of the system to be stored in an isolated expander (or softening water tank), resulting in a high utilization rate of the stabilizer's volume.90Above all, the overall volume and height of the unit have been significantly reduced, resulting in savings in space.50-60Convenient for equipment layout and installation, while also saving on the construction costs of the data center.

2Reliable

   The product utilizes advanced automatic control systems, featuring dual-pump alternating operation and dual-pump simultaneous operation in case of accidental leakage. It also includes low-water level protection and anti-pressure instability误operation functions, ensuring stable operation of the device.

3Energy-saving features

   This product utilizes a stainless steel multi-stage pump and a specially designed voltage stabilizer, enhancing the lifespan of the unit while ensuring optimal operation under various conditions, and boasts energy-saving features.

4Installation Convenient

   Standard floor-standing expansion tanks are generally shipped in kit form, requiring assembly on-site, which increases installation difficulty and reduces equipment reliability. This product, however, is factory-assembled, and all that's needed on-site is to connect the in/out water ports and power supply—simple and quick.

Application Field:

   Central heating, district heating, building heating, domestic hot water, geothermal utilization, air conditioning cooling, seawater desalination, circulating cooling, petrochemicals, food, and various locations requiring heat exchange.

Pressure-Regulated Water Filling Equipment Control Principle:

   Automatic Status: The system pressure is monitored through a remote pressure gauge. The direct connection electric pressure gauge is set for high and low pressure. When the system pressure falls below the set low-pressure value, the water补给 pump starts to replenish water. The replenishment process is complete when the system pressure reaches the set high-pressure value, at which point the water补给 pump stops. If the system pressure drops due to reasons such as drainage, the replenishment process is repeated when the pressure falls below the set low-pressure value again.

   Manual Mode: Set the manual start button to initiate补水 from any of the water pump units. Stop refilling once the desired pressure is achieved by pressing the stop button.
