From the operation of the fire pump, it is not difficult to see that its operation rate is fast, under the action of pressure, its operation process is very smooth, its main standby switching process is controlled by signal:
1, current signal control method: through the feedback of the motor current signal of the water pump, to judge whether the fire pump is working. When the motor short circuit (power failure), the current is too large, the power automatically switches to the motor of another pump set, stop the work of one pump, start the work of the other pump.Fire Pump Equipment
2. Pressure signal control method: the electric node pressure gauge is set on the outlet main pipe of the fire pump, and the switch between the main and standby pumps is judged by the signal of the pressure gauge. When the control box receives the action instruction, start either pump immediately. If the pressure indicated by the pressure gauge of the electric node after the pump works fails to reach the set pressure value, the control box will automatically switch to another pump to start the work.Fire Pump Equipment
Fire pump through the signal control method, to achieve its main standby switching process, improve the efficiency of the use of equipment, switching back and forth, usually in multiple pumps can achieve this function.
