Description
Technical field
Control equipment is controlled the present invention relates to a kind of centrifugal blower more particularly to a kind of paper machine coating cycle hot wind is centrifuged wind
Machine control device.
Background technique
Coating blank is a kind of printing of top grade, it is to apply to coat on body paper, and the paper made has good
Optical property and printing performance etc..Being coated in the production process of blank will be by precoating, and middle painting, back painting, face applies this four coatings
Machine, body paper is every will to have more coating cycle hot wind centrifugal blower bellows to coat into hot wind baking paper by a coating machine
It is dry, if paper coat after coating cycle hot wind centrifugal blower cannot timely hot-air seasoning, idle guide rolls can stick coating influence
Paper quality causes finished paper drop etc. to occur, and thus generates a large amount of substandard products finished papers.
In existing control technology, when coating cycle hot wind centrifugal blower motor directly initiates, because of motor overload thermoelectricity device
Protection value, which occurs now and then, can not avoid generating electric current peak-peak when motor directly initiates, and frequently jump electrothermal relay protection, to lead to
Artificial hand-reset is crossed, very inconvenient, there is also the motor short time starts repeatedly coil is caused to burn out accident.If heat
Relay protection value be transferred to it is excessive, electrothermal relay protection value to day-to-day operation motor overload protection does not play in time protection make
With protection value will cause motor to burn out risk in vain, and fault spread more influences paper quality and causes more finished papers
