Technical Information
The information below is for reference. Final order data is subject to the technical agreement and product nameplate.
I. Product Overview
The SYXW series fire-fighting pneumatic water supply equipment is designed and manufactured by Shanghai Shenyin Pump Industry Co., Ltd. in accordance with national fire safety standards. It is primarily used to maintain pressure and provide supplementary pressure for fire hydrant systems and automatic sprinkler systems.
The equipment consists of a pressure-maintaining pump, a pneumatic tank, a control cabinet, pressure sensors, piping accessories, and an automatic control system. By automatically monitoring pressure fluctuations in the piping network, it controls the start and stop of the pressure-maintaining pump, ensuring the fire-fighting network maintains the required pressure and keeping the fire-fighting system in a state of constant readiness.
Characterized by a high degree of automation, reliable operation, a compact footprint, and ease of installation and maintenance, the product is widely used in high-rise buildings, commercial complexes, industrial plants, hospitals, schools, hotels, and various other fire-fighting water supply systems.
II. Product Features
Automatic Pressure Maintenance
Utilizes automatic pressure control to monitor fire-fighting network pressure in real-time.
When system pressure drops: The pressure-maintaining pump starts automatically to restore pressure.
When system pressure returns to the set value: Operation stops automatically. This ensures the fire-fighting system maintains stable pressure over the long term.
Automatic Pressure Boosting
The equipment promptly compensates for pressure losses caused by factors such as leakage or temperature changes, ensuring the fire-fighting system is always capable of supplying water.
Energy-Efficient Operation
Employs a low-flow pressure maintenance method, operating automatically only when pressure drops, thereby reducing energy consumption and operating costs.
Dual-Pump Backup
Configurable for "one-duty/one-standby" or alternating dual-pump operation with automatic fault switching, enhancing system reliability.
Automatic Control
The control system features automatic operation, manual operation, automatic pump rotation, and automatic fault alarms, eliminating the need for dedicated personnel on duty.
Comprehensive Protection Functions
Includes protection against phase loss, overload, short circuits, undervoltage, and overpressure, as well as fault alarms, ensuring safe, long-term equipment operation.
III. Product Components
The SYXW fire-fighting pneumatic water supply equipment consists of the following main components:
· Fire-fighting pressure-maintaining pump
· Pneumatic tank
· Control cabinet
· Pressure sensor
· Pressure gauge
· Piping valves
· Check valve
· Safety accessories
· Automatic control system
IV. Working Principle
The equipment monitors the pressure of the fire-fighting network in real-time using pressure sensors. When the pipeline network pressure drops below the set value, the control cabinet automatically starts the pressure-stabilizing pump to replenish water and boost system pressure.
Once the pressure reaches the set value, the pressure-stabilizing pump stops automatically; a pneumatic tank stores pressure energy to maintain system pressure stability.
In the event of a fire, the main fire pump activates, the pressure-stabilizing equipment automatically exits its normal operating mode, and the main fire pump takes over the fire water supply task.
V. Scope of Application
Widely used in: fire hydrant water supply systems, automatic sprinkler systems, fire protection systems for high-rise buildings, commercial complexes, hospitals, schools, industrial plants, warehousing and logistics centers, underground garages, and municipal fire protection projects.
