In the prior art, the driving of the fire and smoke exhaust fan is usually carried out by the motor alone. When the power supply system fails, the power supply can only be provided by another road power supply or a standby generator set.
The standby power supply distribution line is relatively complex, with some hidden trouble.
However, along with the fire occurrence and spread, the normal power supply system and standby power distribution lines often were destroyed not the normal power supply, the motor power is lost, resulting in failure of smoke exhaust system and mechanical smoke, resulting in casualties, equipment and property losses.
And the use of a new type of automatic dual power exhaust fan, it can effectively solve the security risks.
In the normal power supply system, the wind turbine driven by the motor, but when the power system failure, equipped with automatic engine start in a short period of time, continue to drive the fan work, guarantee the normal operation of mechanical smoke exhaust system.
Full automatic control automatic inspection, automatic program control, automatic process control, automatic data acquisition and display, automatic fault diagnosis and relay protection.
Full digital direct control (DDC).

Comprehensive information display. Equipment operation state display includes: wait, boot, oil supply, start, start delay, idle delay, normal operation, cooling shutdown, emergency shutdown.
The operation parameters of the equipment include: fan speed, cooling temperature, lubricating oil pressure, running time, fuel stock, starting battery voltage and other parameters.
Equipment protection settings include: speeding, low speed, low oil pressure, high temperature cooling and low temperature (lower than 4 DEG C), low fuel level, low battery voltage, battery voltage, high speed signal without calibration and pump low water pressure and super flow alarm.
No speed signal, speed, low speed, low oil pressure, high temperature, cooling down, failed to start failure, oil pressure sensor, temperature sensor circuit open / short circuit / short circuit, speed sensor open / short circuit, automatic alarm.

The original design of mechanical and electrical integration, users only need to connect into the ventilation pipe can work.
Equipment with communication interface, can be directly connected with the control center to achieve the "four remote" (remote control, remote monitoring, remote monitoring, remote control) monitoring and operation records.
The domestic original diesel engine pump controller is a special chip, curing procedure design, has all the diesel engine pump control program input to the computer chip control, complete function, safe and reliable, without special professional programming.
Usually the city electric drive motor ventilation (low speed).
The normal state of fire in the city, the city electric drive motor smoke (high speed).
City power failure of the fire state, diesel engine exhaust smoke.
The utility model can be widely used in various fields such as mining, building, oil, steam field exploitation, offshore drilling platform, mine, field operation, military and so on.
