How to operate the all-low-voltage capturing machine when it encounters emergency power failure?

When the whole low pressure oxygen generator encounters emergency power failure, the first task is to open the air release valve at the end of the air compressor and close the valve of air entering the distillation tower quickly, in case of the air compressor's outlet check valve failure, which causes compressed air to reverse and causes the air compressor to reverse and burn out the bearing. Follow these steps:
1) turn the switching mechanism from automatic to manual, and close the forced Valve and average pressure switching valve of air entering the tower. Open the sewage nitrogen vent valve.
2) cut off the solenoid valve of the expansion machine, and close the inlet regulating valve of the expansion machine and the inlet and outlet valves of the expansion machine.
3) close the regulating valve of liquid, liquid nitrogen and sewage nitrogen.
4) turn off all the oxygen and nitrogen products and send them out of the valve, and open the vent valve, then put the three-way valve of dirt and nitrogen in the vent side.
5) turn off all the inflated air to enter the disc valve of the upper tower, and open the bypass valve.
6) close the oxygen regulating disc valve, and fully open the dirt nitrogen and pure nitrogen regulating disc valve.
7) turn off the steam gas source of the steam heater.
8) cut off the power switch of the electrical equipment and make it in the starting position.
After finding out the cause of the power failure and eliminating the failure, be ready to start the car.
