In or the influence of transport of fiber flock in cleaner be minimized.
It is further advantageous that leading mode of operation can be determined from cellucotton line by controller.It can prepare system from spinning
The measurement results of the upstream components (for example, such as bale breaker or transportation route) of system administers the function.It is also contemplated that right
Conveying air stream or the quantity of the fiber flock in transport air stream measure.Based on these parameters, cleaner (rotation is adjusted
Speed, grid alignment etc.) and under a certain pressure obtain fiber flock expectation cleaning.However, opposite path is also can
Expect, so that cleaner is manually adjusted a certain yield and thus obtains mode of operation and the mode of operation quilt
For determining the target value of pressure.
It is further advantageous that mode of operation is target that is scheduled and therefore can manually setting pressure on the controller
Value.Therefore, empirical value can be inputted or operation can be executed under the premise of not changing other parameters with the pressure of change.
Particularly advantageously, it is adjusted so that the static pressure in cleaner is constant described in adjustment.When doing so, with based on change
The adjusting of operating parameter compare, do not consider the fluctuation of set target value, and make it possible stable operation.As replacing
