三, a structure, the use of pneumatic machine, by adjusting the motor shaft speed control valve. Sanding and scattered leaf blade and shaft directly connected with thread. 2, the use of qigong movements, so that the long-Box drive down more rapidly and unit weight dropped drastically. 4, use and maintenance of a use will be selected with scattered leaves fixed axis. 2, and spindle adjustments containers level position, clamping containers, covered with containers covered. 3, the use of open source gas valve, and then need to adjust the speed of speed; Shutdown, it should first fall to zero speed, gas source close again. 4, access to natural gas resources in the gas supply valve interface, and then oil-water separator, the pressure was adjusted to 0.6. 5, turning on the import of pneumatic valve motor adjustable motor speed. 6, regulate gas control valve, adjustable rate movements (the factory has adjusted well), should not take it too fast, machines to avoid injury. 7, rotary valve, the machine can increase or decrease, declining to be slow rotating valve, so that machines slow down, for the machines to have an impact. 8, scattered leaves is not installed, the speed is greater than 3000r / min should not open empty, otherwise damaged spindle.
