Performance characteristics of diesel engine fire pump

When the diesel engine fire pump unit receives an effective fire signal, if the power supply system of the diesel engine fire pump is powered off, loses phase or the electric pump cannot start normally, the diesel engine fire pump unit will automatically start to run. Once the power supply system returns to normal or the electric pump can operate normally, it can automatically switch to the electric pump.
