The inner heating device 7 of device nacelle 1 can be preheated to pending article, to prevent what is discharged in processing procedure by condensation
Heat causes processed material surface temperature too high and the phenomenon of generation damage.
(4) it is easy to operate, record full and accurate.The device has the control system of independent design, can to inhomogeneous processed material
Set up and store corresponding processing technological flow.It can be directly invoked with the flow of storage, so as to realize the purpose of key operation.
Meanwhile, during technological process is run, the instant switching between different step, the modification of parameter can be achieved.Meanwhile, benefit
In the control system, the time interval of data record can narrow down to every five seconds for example once.
(5) temperature accuracy is high, and each regional temperature is uniform.The control system precision of the device is calculated, immediately to transmission valve
The folding degree of progress is controlled, and the temperature accuracy inside nacelle is can be controlled in the range of ± 0.3 DEG C.Wind inside nacelle
Machine can effectively facilitate the circulation of inner air, it is ensured that in the uniformity of the processed material heating rate of nacelle different zones.
Embodiment of above is only that the preferred embodiment of the present invention is described, and not the scope of the present invention is entered
Row is limited, on the premise of design spirit of the present invention is not departed from, technical side of this area ordinary skill technical staff to the present invention
In various modifications and improvement that case is made, the protection domain that claims of the present invention determination all should be fallen into.
