C) compare with average wind-warm syndrome in the path of board or wind speed obviously on the low side to the wind-warm syndrome or the wind speed of position, following four paths of same hot blast manifold; The equal wind orifice plate replacement littler than former equal wind orifice plate windage used in unification instead; Compare with average wind-warm syndrome in the path of board or wind speed obviously highly to the wind-warm syndrome of position, following four paths of same hot blast manifold or wind speed, unified using instead than the big equal wind orifice plate of former equal wind orifice plate windage replaced former equal wind orifice plate.
Scheme is that the spinning channel wind control method further comprises step preferably: d) position of changing under the same hot blast manifold behind the equal wind orifice plate, four paths is surveyed wind-warm syndrome once more or surveyed wind speed; If the wind-warm syndrome or the wind speed of position, four paths have notable difference; C set by step again) continues adjustment; So repeatedly, meet the setting requirement, and meet the setting requirement with difference with average wind-warm syndrome in board path or wind speed until the wind-warm syndrome of position, four paths, the difference of wind speed.
The control method that better scheme is a spinning channel wind further comprises step: e) adopt thermometric or anemobiagraph to measure the wind-warm syndrome and the air speed data in all paths in same the spinning machine, confirm whether reduce with the standard deviation of all path wind-warm syndrome of board and wind speed.
Good again scheme is that the control method of spinning channel wind further comprises step: if f) standard deviation of path wind-warm syndrome or wind speed does not reduce, and repeating said steps b then) to step e), reduce until wind-warm syndrome or wind speed standard deviation.
The present invention is according to the path wind speed or the wind-warm syndrome data cases of test; Adopt the equal wind orifice plate of different size to replace the equal wind orifice plate of unified specification in the past; Can reduce wind-warm syndrome or wind speed standard deviation effectively with each position, path of board; Make the distinguished and admirable condition of each position, path more even, thereby reduce phenomenons such as coagulating silk, broken end, flyings, improve the spinning speed of production.
The specific embodiment
