The distribution line of standby power supply is complicated, and there are some hidden dangers.
However, with the occurrence and spread of fire, the normal power supply system and standby distribution lines are often destroyed, which leads to the failure of mechanical smoke control and extraction system, resulting in casualties, equipment and property losses.
Adopting a new type of fully automatic dual-power smoke exhaust fan can effectively solve this safety hazard.
Under the normal power supply system, the fan is driven by the motor, but when the power supply system fails, the equipped engine will automatically start in a short time and continue to drive the fan to work, so as to ensure the normal operation of the mechanical smoke control and extraction system.
Fully intelligent control-automatic detection, automatic program control, automatic process control, automatic data acquisition and display, automatic fault diagnosis and relay protection.
All digital direct control (DDC).
Comprehensive information display. The equipment operation status display includes: waiting, startup, oil supply, startup, startup delay, idle delay, normal operation, cooling shutdown and emergency shutdown.
The display of equipment operation parameters includes: fan speed, cooling temperature, lubricating oil pressure, running time, fuel stock, starting battery voltage and other parameters.
Equipment protection settings include: overspeed, low speed, low oil pressure, high cooling temperature, low air temperature (below 4℃), low oil level, low battery voltage, high battery voltage, uncalibrated speed signal, low water pump pressure and excessive flow.
No speed signal, overspeed, low speed, low oil pressure, high cooling temperature, startup failure, shutdown failure, open/short circuit of oil pressure sensor, open/short circuit of water temperature sensor, open/short circuit of speed sensor, etc. The original electromechanical integration design in China allows users to work only by connecting the ventilation pipes in and out.
The equipment has a communication interface, which can be directly connected with the control center to realize "four remote" (remote adjustment, remote communication, remote monitoring and remote control) monitoring and operation record.
The original diesel water pump controller in China is a special chip with curing program design. The control program of diesel water pump has been completely input into the computer chip, with complete control functions, safety and reliability, and no special programming is needed.
At ordinary times, the commercial power drives the motor for ventilation (low speed).
Under the normal fire alarm state of the commercial power, the commercial power drives the motor to exhaust smoke (at high speed).
Drag the diesel engine to exhaust smoke in the fire alarm state of mains power failure.
It can be widely used in industrial and mining, construction, oil and gas fields, offshore drilling platforms, mines, field operations, military and other fields, and has good national defense value, social and economic benefits and popularization and application prospects.
