[0022] Here’s how it works: 1 Damper open like Figure 2 As shown, the operator rotates the damper switch SK1 to the open position. At this time, the ventilation knob SK1 is turned on, and the KZ10 intermediate relay coil is energized. After the KZ10 coil is energized, the KZ10 contact is closed, and the electric push rod M3 ( Figure 3 ) in the positive direction from the lower limit to the upper limit. When the electric push rod touches the upper limit XK1 ( Figure 4 ), XK1 open limit is connected, and the coil of intermediate relay KZ1 is energized ( Figure 4 ), at this time KZ1 relay ( Figure 2) contacts are disconnected, the coil of the intermediate relay KZ10 is de-energized, and the contacts of KZ10 are disconnected ( Figure 3 ), the electric push rod M3 stops moving, and the air door is in a fully open state.
[0023] When the operator turns on the SK1 ventilation knob, the KZ10 intermediate relay coil is energized. After the KZ10 coil is energized, the KZ10 contact closes ( Figure 4 ), KZ18 coil is energized and self-locking is completed, and the damper opening signal KZ18 contact is closed ( Figure 1 ), at this time, the damper opening signal is sent to the inverter DI3 terminal. At this time, the inverter receives a damper opening signal, the inverter output frequency is 25% of the full frequency, and the fan output speed is 25% of the full speed; if you want to open the remaining 3 damper switches, you can open the damper in the above way. At the same time, after the inverter receives the damper opening signal, the output frequency is adjusted from 25% to 50%, 75%, and 100%, and the corresponding fan output is adjusted to 50%, 75%, and 100% of the full speed.
[0024] 3.2 Damper closed 3.2.1 Manual closing and air volume adjustment like Figure 2 As shown in the figure, after the workpiece is polished, the operator turns the air door switch SK1 to the off position, and the KZ11 intermediate relay coil is energized. After the KZ11 coil is energized, the KZ11 contact closes ( Figure 3 ), at this time, the electric push rod M3 ( Figure 3 ) moves downward from the upper limit to the lower limit. When the electric push rod touches the lower limit XK2 ( Figure 4 ), XK2 closed limit is connected, and the intermediate relay KZ2 coil is energized ( Figure 4 ), at this time KZ2 relay ( Figure 2 ) contacts are disconnected, the coil of the intermediate relay KZ11 is de-energized, and the contacts of KZ11 are disconnected ( Figure 3 ), the electric push rod M3 stops moving, and the air door is in a fully closed state.
[0025] When the operator turns the damper switch SK1 to the closed position, the KZ11 intermediate relay coil is energized. After the KZ11 coil is energized, the KZ11 contacts are closed ( Figure 3 ), at this time, the electric push rod M3 ( Figure 3 ) moves downward from the upper limit to the lower limit. When the electric push rod touches the lower limit XK2 ( Figure 4 ), XK2 closed limit is connected, and the intermediate relay KZ2 coil is energized ( Figure 4 ), after the KZ2 coil is energized, the KZ2 contact is disconnected ( Figure 4 ), KZ18 coil is powered off. At this time, the inverter input signal KZ18 contact is disconnected ( Figure 1), the inverter output frequency is reduced by 25%, and the fan output speed is reduced by 25%; and so on (the other three workstations are closed), the inverter output frequency is reduced by 50%, 75%, and 100%, and the fan output speed is reduced by 50%, 75%, and 100%.
[0026] 3.2.2 Automatic shutdown and air volume adjustment like Figure 2 As shown in the figure, after the workpiece is polished, if the operator forgets to close the air door, the infrared sensor TCQ1 ( Figure 5 ) will count the time when the operator is away (timer JS2). If the operator is away for more than 30 minutes, the JS2 delay relay coil will be connected. The delay relay JS2 contacts will close ( Figure 2 ), the KZ11 intermediate relay coil is energized. After the KZ11 coil is energized, the KZ11 contact closes ( Figure 3 ), at this time, the electric push rod M3 ( Figure 3 ) moves downward from the upper limit to the lower limit. When the electric push rod touches the lower limit XK2 ( Figure 4 ), XK2 closed limit is connected, and the intermediate relay KZ2 coil is energized ( Figure 4 ), at this time KZ2 relay ( Figure 2 ) contacts are disconnected, the coil of the intermediate relay KZ11 is de-energized, and the contacts of KZ11 are disconnected ( Figure 3 ), the electric push rod M3 stops moving, and the air door is in a fully closed state.
[0027] When the delay relay JS2 contacts are closed ( Figure 2 ) at the same time, after the KZ11 coil is energized, the KZ11 contact closes ( Figure 3 ), at this time, the electric push rod M3 ( Figure 3 ) moves downward from the upper limit to the lower limit. When the electric push rod touches the lower limit XK2 ( Figure 4 ), XK2 closed limit is connected, and the intermediate relay KZ2 coil is energized ( Figure 4 ), after the KZ2 coil is energized, the KZ2 contact is disconnected ( Figure 4 ), KZ18 coil is powered off. At this time, the inverter input signal KZ18 contact is disconnected ( Figure 1 ), the inverter output frequency is reduced by 25%, and the fan output speed is reduced by 25%; and so on (the other three workstations are closed), the inverter output frequency is reduced by 50%, 75%, and 100%, and the fan output speed is reduced by 50%, 75%, and 100%.
