Product Description
According to the standard 1.0.4 of GB50974-2014, "Technical Specifications for Fire Water Supply and Fire Hydrant Systems", a flow switch or pressure switch should be installed on the outlet pipe of the high-level fire water tank to directly start the fire pump. According to the new standard GB509742014.11.0.19, the reliability of pump starting is often affected by the loss of weak electrical signals. Therefore, the necessity of starting the fire pump via the fire hydrant box button is low, and the investment in fire hydrant button pump starting is relatively large. Thus, the fire hydrant button should not be used as a direct pump starting signal, but only as an alarm signal. A flow switch is installed on the outlet pipe of the high-level water tank, and a digital flow meter and flow rate meter are displayed on the device control panel. When the flow exceeds the set value, it serves as a pump starting signal. A pressure switch is also installed on the device control panel, digitally displaying real-time pressure (the natural static pressure of the water tank and the outlet pressure of the pressure-stabilizing pump). When the high-level water tank and the static pressure-stabilizing pump pressure cannot support the large water flow during a fire, the pressure drops suddenly. When it drops to the set pressure, it serves as a reliable signal for directly starting the fire pump.
