Principle of work: the temperature controller PT of proofing box adopts digital display type temperature controller. This controller temperature control wide ranges (0-250 DEG C), probe adopts platinum resistance Pt100; Output terminal be one to normal open contact unify to normally closed interlock, by its built-in rly. is controlled. Principle of work is any setting one holding temperature within the scope of its temperature control in advance, and when temperature rises to this holding temperature, the built-in relay of temperature controller obtains electric adhesive, and now output terminal obtains that normal open contact is closed and normally closed interlock disconnects; And when temperature is brought down below holding temperature 0.1-0.2 DEG C, built-in relay power-off discharges, normal open contact and normally closed interlock reset. Concrete that heat-processed is as follows:
Pressing+heat button switch, obtain normally closed interlock (b1, b2) by time relay sj, rly. obtains electric adhesive and self-locking, and temperature controller PT obtains power supply and is switched on and start working (temperature controller should first set test temperature); Ac solid relay SSR also obtains a DC24V and obtains input voltage, and output terminal starts conducting work, and via the normal open contact of KM2 and the normally closed interlock (a1, a2) of temperature controller PT to the input terminus of SSR, now heating tube electrified regulation heats up.
When temperature rises to design temperature, output normally closed interlock (a1, a2) of temperature controller PT disconnects, the input voltage of ac solid relay SSR is also disconnected simultaneously, output terminal by, now heat-generating pipe stops heating, starts cooling; When temperature is brought down below holding temperature, the built-in relay of temperature controller PT obtains electric adhesive, and normally closed interlock (a1, a2) resets, and ac solid relay SSR works again, and heat-generating pipe starts to heat again, enters next circulation. Make full use of like this ac solid relay without contact, control flexibly, the advantage such as action is fast, silent running carry out the heating of break-make heat-generating pipe, effect is much better than alternating current contactor.
Timing is incubated Automatic Control Theory;
Time relay sj should pre-set soaking time value.When temperature rises to holding temperature, the normal open contact (a1, a2) of temperature controller PT output terminal closes, and now, relay K M3 obtains electric adhesive and self-locking, and the power supply of time relay sj is connected and timing of starting working, and enters timing and is incubated the automatic stage. After reaching preset soaking time, after namely time delay terminates, the normally closed point (b1, b2) of the output of SJ disconnects, and heating relay K M2 dead electricity disconnects, and temperature controller PT, ac solid relay SSR, fever tablet EH all stop work. Now heating, be regularly incubated and terminate, whole process is and automatically completes, and without manual time-keeping, operates very convenient, reliable.
The beneficial effects of the utility model are: 1, saved an input fund in renewal and renovation of equipment, testing apparatus of the present utility model, substantially meet the requirement of control automatically, and cost is extremely low, only needs 4-5 thousand yuan;
2, in energy-conservation, not taking the testing apparatus of new design, due to the frequent loose contact of contact of the alternating current contactor of heating, wire often generates heat, and affects heat-up rate, loss of energy. After repacking, replacing alternating current contactor with ac solid relay, make full use of the advantage of solid state relay, not only heat-up rate improves, and there is not the bad phenomenon of contact, and wire does not also often generate heat, widely save energy;
3, the service work of serviceman's testing apparatus is alleviated; Before not adopting new design, often being changed alternating current contactor, the heating of wire even fuses, and makes that connecting position of wires is also often oxidized, loose contact and rewiring; Maintenance work is many, cumbersome;
4. the plug perforate of insulcrete design is the type having multiple country; The plug test of different country can be facilitated. Promote the efficiency of test.
