It is designed to ensure that the fire pump can start in time and provide sufficient water when needed. This device combines components such as pressure regulation control, noise and vibration reduction, and automatic switching to form a stable water supply system for fire protection systems. The core functions of the fire pump pressure stabilizing control device include automatically starting and stopping the fire pump.

[0003] Excessive pressure may cause damage to components such as the pump seals, bearings or impellers, and may even cause the pump casing to rupture. It may also cause the rupture of accessories, which may cause fragments to fly and cause harm to on-site workers. Damaged equipment needs to be repaired or replaced, which will bring high maintenance costs and affect the response capability of the fire protection system.

[0004] Therefore, in view of the fact that the above-mentioned excessively high pressure may cause damage to components, harm on-site workers, and result in high repair costs, a signal device on the pressure detector can be designed to be connected to the controller to monitor the system pressure in real time and automatically start or stop the pressure-stabilizing pump according to the pressure changes.

A pressure detector 8 (the model of the pressure detector 8 is MPX5010) is provided on the outside of the water outlet 19. The outside of the pressure detector 8 is electrically connected to a signal device 18 (the model of the signal device 18 is M5TS-24-R / K / BL). Wiring is performed through dedicated connection holes to avoid cluttered cable layout, improve the neatness of the system and facilitate maintenance. The pressure detector 8 can monitor the system pressure in real time to ensure that pressure changes can be detected in time at any time. Through real-time monitoring, the system can respond to pressure changes more quickly, improving the system's response. Speed ​​and stability, the pressure sensor inside the air pressure tank 2 can monitor the pressure inside the tank in real time, and transmit it to the control cabinet 4 through wires to ensure that the system pressure is stable. The surface of the air pressure tank 2 is provided with a first wire hole 6 corresponding to the first connection hole 9, and the surface of the air pressure tank 2 is provided with a second wire hole 7 corresponding to the second connection hole 10. The dedicated wire hole can reduce external interference and improve the reliability of signal transmission.

The dedicated wire hole ensures that the wires are firmly connected, reduces signal transmission problems caused by looseness or poor contact, can avoid friction or collision between the wires and external objects, and reduce the possibility of physical damage.

[0024] See also Figure 3 - Figure 4 In this embodiment, a control panel 14 is provided on the inner surface of the control cabinet 4. A connecting block 12 is provided on the side of the control panel 14 away from the first connecting hole 9. By installing the connecting block 12 on the side away from the first connecting hole 9, the interference of the incoming and outgoing cables on the control panel 14 can be reduced, thereby improving the reliability of the system. The connecting block 12 centrally manages the wiring of external devices and sensors, reduces the clutter of cables, and improves the neatness and reliability of the system. The design of the connecting block 12 can prevent short circuit problems caused by chaotic wiring and improve the safety of the system. A connecting rod 13 connected to the control panel 14 is provided on the outside of the connecting block 12.

[0025] See also Figure 1 - Figure 3 In this embodiment, the surface of the control panel 14 is provided with an air pressure tank switch 16 and a pressure regulating pump switch 17. The surface of the control panel 14 is provided with a controller 15 (the model of the controller 15 is S7-200) located below the air pressure tank switch 16. The signal device 18 transmits a signal to the controller 15 to control the air pressure tank switch 16 and the pressure regulating pump switch 17 to be closed. The setting of the air pressure tank switch 16 and the pressure regulating pump switch 17 allows the operator to manually control the working status of the air pressure tank 2 and the pressure regulating pump 3, which is convenient for manual intervention when needed. By concentrating the switch and the controller 15 in the same area, the operation is more intuitive and convenient. When a fault occurs, emergency treatment can be carried out by manually controlling the switch to reduce the risk of system out of control. An air valve 20 is provided on the outside of the air pressure tank 2, and a water inlet 21 is provided at the bottom of the air pressure tank 2. The gas pressure in the air pressure tank 2 can be adjusted at any time through the air valve 20 to ensure that the air pressure tank 2 is always in the best working condition. The setting of the air valve 20 allows the operator to easily adjust the gas pressure in the air pressure tank 2, which is convenient for maintenance and inspection. The water inlet is located at the bottom of the air pressure tank 2, which is convenient for filling water into the tank to ensure that there is enough water in the air pressure tank 2. By optimizing the structure of the air pressure tank 2, it can be ensured that the system can operate stably under any circumstances and respond to pressure changes in time.

[0026] When working, first control the start of the pressure-stabilizing pump 3 and the pressure tank 2 through the air pressure tank switch 16 and the pressure-stabilizing pump switch 17 on the control panel 14, transmit water to the air pressure tank 2 through the water inlet 21, stabilize the water pressure through the air pressure tank 2 and the pressure-stabilizing pump 3, and connect the stabilized water pressure to the fire water pipe through the water outlet 19 for fire fighting. When the pressure exceeds the preset value, the pressure detector 8 monitors this change in real time and transmits the signal to the controller 15. The controller 15 will control the air pressure tank switch 16 and the pressure-stabilizing pump switch 17 to be closed, and at the same time start the alarm 11 to sound an alarm to remind maintenance personnel to perform maintenance to ensure that the fire pump will not explode or cause damage to components. When the maintenance is completed, restart the air pressure tank 2 switch and the pressure-stabilizing pump 3 switch.

[0027] Through the above steps, the system pressure can be monitored in real time by connecting the signal device 18 on the pressure detector 8 with the controller 15, and the pressure-stabilizing pump 3 can be automatically started or stopped according to the pressure change, so as to ensure that the system pressure is always maintained within the preset range, avoiding instability caused by pressure fluctuations, and reducing the risk of excessive or low pressure due to operational errors or human negligence by automatically controlling the start and stop of the pump. If the system fails, such as when the pressure sensor senses that the pressure is too high or too low, the control panel 14 will control the alarm 11 to sound an alarm, prompting the operator to check or maintain. Through automated control, the need for manual intervention is reduced, the operating efficiency and management level of the system are improved, and the problem that excessive pressure may cause damage to components, cause harm to on-site staff, and result in high maintenance costs has been solved.
