OK.It is fortune when ribbon conveyer is in normal operating condition under the component effect along conveyer transporting direction to put operating mode of stopping
Scanning frequency degree can accelerate even hypervelocity, and now whether disk brake can exceed the speed limit according to the velocity estimated that brake disc feeds back, such as
Fruit hypervelocity will inlet point stop pattern, belt conveying motor speed is dropped to normal work speed once progressively；Point is stopped under pattern, first
First motor 3 will start (having been turned on, keep), and the first solenoid directional control valve 11 is kept as electricity, and 10 electric signal of proportional pressure control valve keeps
In setting value, the second solenoid directional control valve 16 electric, now, 10 electric signal of proportional pressure control valve by press certain frequency from 0 to setting
Value quickly changes, and system pressure is quickly changed from 0 to setting value, and now braking in front can be according to certain frequency either on or off
Formation point is stopped and makes belt conveying motor speed progressively drop to normal work speed, when the velocity sensor in brake disc detects speed
After dropping to normal work speed, the point pattern of stopping terminates, and proceeds to automatically normal work operating mode.Damped condition is stopped in ribbon conveyer
Only work or required working condition during brake hard, now controller receives brake signal, proceeds to damped condition immediately,
Motor 3 stops operating, 11 dead electricity of the first solenoid directional control valve, and the high-voltage oil liquid in accumulator 17 is by choke valve 12 according to once
Speed discharges, and brake is braked.
