Fire-fighting voltage regulator equipment pictures and classification
[ Huaqiang Security Network News ]
This article introduces the classification and picture sharing of fire-fighting power supply equipment. First of all, we know that the new series of fire-fighting special fixed fire-fighting water supply equipment designed by the national 98S25 latest standard includes Wsv-zw "L) vertical WSY-ZW (W) Lili There are ten varieties of horizontal and horizontal series. It is composed of pressure pressure pump, air pressure young, control side box, instrument farm, Gandao attachment, etc. It is widely used in multi-layer and single-layer construction engineering. The required fire hydrant water supply system. When the fire alarm does not occur and the system is in automatic operation, the pressure sensor on the fire pipe network samples the water pressure of the pipe network, converts the pressure signal into an electrical signal, transmits it to the PID regulator, and then sets the pressure value with the user. Performing comparison and calculation, and converting the result of the comparison and calculation into a frequency adjustment signal and a steady-state pump starting number signal are respectively sent to the frequency converter and the programmable controller (PLC): the frequency converter adjusts the electric frequency of the pump motor, and further Adjust the rotation of the pump: The programmable controller controls the operation of the constant pressure pump according to the pump start number signal transmitted from the PID regulator. Through the adjustment of the number of starting and stopping of the pump and the speed of the positive-frequency variable-voltage running pump, the user's fire-fighting pipe network pressure is stabilized at the user's preset pressure value to maintain the minimum fire pressure, so that the whole system In fire prepared state. When the fire alarm occurs, once the control cabinet receives the pump signal from the station control room, it immediately starts the main fire pump and turns off the steady pressure water pump to provide the rated fire water to meet the requirements of the fire water filling water column. After the fire command is released, manually turn off the fire main pump to restore the daily steady state of the equipment. Meet the requirements of fire water filling water column. After the fire command is released, manually turn off the fire main pump to restore the daily steady state of the equipment.

Fire-fighting voltage regulator equipment classification
Fire rated water supply equipment
It is used to maintain the fire water supply equipment with stable pressure in the service state of the fire water supply system.
Fire booster water supply equipment
The fire pumping unit is used to raise the fire water source pressure to meet the fire water supply system needs of the fire water supply system.
Fire booster pressure regulator combined water supply equipment
Fire water supply equipment that can meet both regulation and boost applications.
Fire-fighting without negative pressure (stacking) stabilized water supply equipment
Directly connected in series to the water on the pressure pipe network, can effectively use the pressure of the pipe network and does not produce negative pressure hazard fire-fighting water supply equipment.
