FQL automatic fire control water supply equipment gas pressure retention, impact prevention, fire water flow stability, automatic control, complete functions, complete interface.FQL automatic fire control water supply equipment electronic control system is composed of frequency conversion governor, programmable controller, pressure setter and low electrical circuits.The equipment has two working modes: manual and automatic. Manual is used for equipment debugging, maintenance and water supply under special circumstances.Under daily conditions, the equipment is placed in automatic position to realize automatic operation.When the equipment is used in a pure fire fighting system, it is usually operated intermittently by a pressure stabilizing pump or (fire fighting pump).For fire control pipe network and the buffer tank filling water, make the pipe network pressure drops rapidly, voltage regulator pump starts, pipe pressure is still unable to maintain, has variable frequency soft start fire pump in fire fighting, fire pump operation adopted by soft start and constant pressure variable, namely when a pump water supply cannot meet the demand of water, putting the department into city electrical frequency operation, and variable frequency soft start the pump,Until the standby fire pump is started, after the fire pump is started, the frequency of the frequency converter increases with the increase of water consumption, so that the pump speed increases, the water supply increases, and the pressure of the pipe network is maintained constant at the pre-equipment value.For equipment without a pressure regulator tank, the frequency converter drives the pressure regulator pump to run continuously and low to stabilize the pressure of the pipe network at ordinary times. When a fire breaks out, the fire pump is gently started in turn to extinguish the fire.In order to prevent the increase of water temperature in the pump during the operation of the stabilized pressure pump due to the small leakage of the pipe network, a primary water pipe is added in the outlet pipe of the equipment to make the water circulation in the pump, so that the temperature rise is not too high.Can also choose when the head is higher than the fire pump pressure pump, in order to reduce its speed.

That is to start each fire pump by frequency conversion soft regularly, and run at low speed for a short time to prevent long-term use of "rust death".When the water equipment of FQL automatic fire control and pressure stabilizing water supply is used in the fire fighting and living common water supply system, the fire pump normally operates in the WPS working mode, with regular rotation and constant variable water supply.The pressure setting value must be adjusted according to fire protection requirements.Double constant pressure operation mode can also be adopted, that is, the life pressure is set as a low value, the fire pressure is set as a high value, and the water is supplied at a low constant pressure at ordinary times. After the fire alarm, the water is automatically transferred to the high pressure value.For XZH type water supply equipment with pressure tank, it can realize regular rotation of fire pump, constant pressure variable water supply when normal water consumption, small flow at night, the pressure of pipe network is maintained by the pressure tank.The gas tank is more suitable for fire hydrant and automatic sprinkling system because it has a certain amount of fire storage water.Equipment using frequency inspection and fire at low speed when the fire pump by soft start, effectively avoid the stress of other fire control devices on the network, and fire extinguishing constant pressure water supply, fire fighting effect is better, so the equipment is suitable for high-grade hotels, restaurants and other high-rise buildings in fire protection, spray system, and other various types of fire water supply system.

Our company FQL automatic fire control water supply equipment using computer control, centralized height, logic processing function is strong, flexible program so as to achieve the fire management of no man.In order to ensure the rapid start of the equipment in case of fire, there is an automatic inspection program, and the automatic inspection can be carried out at any time, and a variety of monitoring interfaces are provided for users to choose.The product has passed the appraisal of the fire bureau of shandong public security department, and has passed the inspection of the national fixed fire extinguishing system and fireproof components quality supervision, inspection and testing center. We are willing to do the safety guard of the vast number of users with excellent product technology and high-quality after-sales service.

FQL automatic fire-fighting and pressure-stabilized water supply equipment is designed and manufactured according to Code for Fire Protection of High-rise Civil Building Design, Code for Fire Protection of Building Design, Code for Design of Automatic Sprinkler Fire-extinguishing System and Local Fire-fighting Standard, and is widely used in various civil buildings and public buildings.Fire hydrants and spray water supply in various buildings, common water supply for living and fire fighting of various buildings, water curtain and rainwater supply of various buildings, etc.

Features of FQL Fully Automatic Pressurized Fire Protection Water Supply Setting Equipment:

Small pump frequency conversion to maintain pressure, such as two small pumps can be regularly interchangeable operation, to ensure the reliability of the system.Large pump timing automatic inspection can also be manual inspection at any time, to ensure the normal operation of the whole equipment.
The small pump pressure keeping system can also be equipped with a small pressure tank, which can make the small pump run intermittently.
In order to ensure the normal operation of the equipment, the product will enter the self-locking working state after receiving the fire signal, so as not to cause the wrong action to stop the machine and thus affect the use. If you want to stop the machine, you must re-close the switch.
The unit has compact structure, small footprint and easy maintenance.

Under normal condition, the pressure stabilizing pump operates with frequency conversion to maintain the pressure required by the fire fighting system.In case of fire, the fire signal will be sent to the control cabinet to automatically start the fire pump, and the pressure controller will ensure the constant pressure operation of the main fire pump at power frequency.

Water supply flow: 10-100L/S
Water supply pressure: <2.7Mpa
Fire fighting reaction time: <30s
