And be connected with switch board by signal cable respectively；Epicoele temperature sensor and cavity of resorption temperature sensor set respectively
Put on the hot plate in upper and lower chamber, and be connected with switch board by signal cable respectively.
Compared with prior art, the utility model has the advantages that: after using this temperature control system, in debugging not
There is electrically-controlled valve clamping stagnation situation again, can by the sensitivity of adjustment programme and algorithm reduce valve start frequently and
The protection produced.Through empty machine and the temperature control of real load, temperature measured value deviation range is at+3.5 DEG C, between-4 DEG C,
And upper and lower hot plate temperature can regulate and control respectively, meet technical property requirements.This temperature control system can be pressed effectively
According to program, curing temperature being carried out control by stages or long-time thermostatic control, temperature-controllable precision exists
+ 4 DEG C, change between-4 DEG C, and precision is higher.The product appearance making sulfuration is good, mechanics properties testing
Qualification rate is high.Concrete manifestation is as follows:
(1) this temperature control system keeps after can realizing design temperature automatically, it is also possible to realize sequencing from
Move and progressively heat up or lower the temperature, meet the requirement to temperature of the thick product sulfuration process.
(2) use temperature control system of the present utility model only the pipe fitting of original deep fat to be replaced, and increase
Software control part, on environment without impact.
(3) existing operator and management personnel are constant, slightly train, and can correctly operate.This system
Only need to set temperature and program, program setting complexity is with the setting operation of current vulcanizer, it is not necessary to special
Different training.
(4), when installing, do not affect other boards and use.
