What is the difference between the straight line of fire pump and the straight line of hydrant?
Straight up is the switch control cabinet, 380V directly pumping. Fire hydrant is connected to 24V, fire control center is connected with control cabinet and pump is renewed
Fire pump start is 380V, fire hydrant button is 24V, the line of course not the same
Fire water pump straight up line, ZR-KVV is the fire engine, directly start the water pump control lineFire hydrant straight up line with ZR-RVS is hydrant button to start the water pump control lineIt should be so
