WZG fully automatic water supply equipment model

The electronic control system consists of a frequency converter, a programmable controller, a pressure setter, and low voltage electrical circuits. The equipment has two working modes: manual and automatic. Manual is used for equipment debugging, maintenance, and water supply in special situations. In daily situations, the equipment is placed in automatic mode to achieve fully automatic operation. When the equipment is used in a simple fire protection system, it is usually operated intermittently by a stabilizing pump or (fire pump). Supplement water to the fire protection pipeline network and stabilizing tank to rapidly reduce the pressure of the pipeline network. If the stabilizing pump cannot maintain the pressure of the pipeline network after starting, a variable frequency soft start fire pump will be put into use to extinguish the fire. The operation of the fire pump adopts a soft start and constant pressure variable working mode one by one. That is, when the water supply of one pump cannot meet the water demand, the system will be switched to the mains power frequency operation, and the variable frequency soft start of the next pump will be used until the fire standby pump is started. After the fire pump is started, the frequency of the frequency converter will increase with the increase of water consumption, so that the pump speed will increase, the water supply will increase, and the pipeline pressure will be maintained at the predetermined equipment value. For equipment without a stabilizing tank, the stabilizing pump is driven by a frequency converter to operate continuously at low levels to stabilize the pipeline pressure. In case of a fire, the soft start fire pump is sequentially activated to extinguish the fire. To prevent the water temperature inside the stabilizing pump from rising during stable operation due to small leakage in the pipeline network, a return pipe is added to the equipment outlet main to circulate the water inside the pump and prevent excessive temperature rise. A stabilizing pump with a head higher than the fire pump can also be used to reduce its speed.

Equipped with automatic inspection function. Regularly start each fire pump with variable frequency soft start, and perform short-term low-speed operation to prevent long-term non use and "rusting". When the FQL fully automatic fire stabilizing water supply equipment is used in a fire and domestic shared water supply system, the fire pump usually operates in the WPS working mode, with regular rotation and constant variable water supply. The pressure setting value must be adjusted according to fire safety requirements. It is also possible to adopt a dual constant pressure operation mode, where the living pressure is set to a low value, the fire pressure is set to a high value, and the water supply is usually supplied at a low value and constant pressure. After the fire alarm is triggered, it automatically switches to high pressure operation. For XZH type water supply equipment with pressure tank, it can achieve regular rotation of fire pump and constant pressure variable water supply during normal water consumption, and maintain pipeline pressure with pressure tank for small flow at night. Due to its certain fire water storage capacity, gas cylinders are more suitable for fire hydrants and automatic sprinkler fire extinguishing systems. The equipment adopts frequency conversion low-speed inspection and soft start of each fire pump during fire alarm, effectively avoiding pressure impact on other fire protection devices on the pipeline. In addition, constant pressure water supply is used for fire extinguishing, and the fire extinguishing effect is good. Therefore, the equipment is suitable for fire protection, sprinkler systems, and other types of fire water supply systems in high-end hotels, restaurants, and other high-rise buildings.

The fully automatic FQL fire stabilizing water supply equipment is a new generation of intelligent unmanned management equipment developed and researched by our factory Our company's FQL fully automatic fire stabilizing water supply equipment adopts advanced microcomputer control, centralized height, strong logical processing function, and flexible and variable program to achieve unmanned management of fire protection. To ensure that the equipment can be quickly started in case of fire, an automatic inspection program is developed, which can be carried out at any time with scheduled automatic inspections, and various monitoring interfaces are provided for users to choose from. This product has been appraised by the Shandong Fire Department and has passed the inspection and testing of the National Fixed Fire Extinguishing System and Refractory Component Quality Supervision and Testing Center. We are willing to be the safety guardian of our customers with excellent product technology and high-quality after-sales service.
Scope of application:
The FQL fully automatic fire stabilizing water supply equipment is designed and manufactured in accordance with the "Code for Fire Protection Design of High rise Civil Buildings", "Code for Fire Protection Design of Buildings", "Code for Design of Automatic Sprinkler Systems", and "Local Fire Protection Standards", and is widely used in various civil and public buildings. Indoor fire hydrants and sprinkler water supply for various types of buildings, shared water supply for daily life and fire protection in various types of buildings, and water supply for fire protection systems such as water curtains and rain showers in various types of buildings.

Features:
The control cabinet adopts a programmable controller with high precision, good reliability, fast response speed, and is equipped with water level control and various fire signal control interfaces.
Variable frequency pressure maintenance of small pumps, if two small pumps are used, they can be operated interchangeably at regular intervals to ensure the reliability of the system. The scheduled automatic inspection of the large pump can also be manually inspected at any time to ensure the normal operation of the entire equipment.
The small pump pressure holding system can also be equipped with a small pressure tank, which can allow the small pump to operate intermittently.
To ensure the normal use of the equipment, this product enters a self-locking working state upon receiving a fire signal, in order to avoid erroneous actions that may cause the machine to shut down and affect its use. If the machine needs to be shut down, it must be reconnected.
The unit has a compact structure, occupies a small area, and is easy to maintain.
