5.3.1.2.THE FIRST TIMES HEATING STAGE(Fig.5.3-5)
When the vacuum value reachs Pv value,the contrl system will open the water pump-solenoid valve(Ev2).The steam generator start to inject the
steam into chamber.The temperatures(T1 and T2) and pressure inside the chamber will be rised at the same time.
5.3.1.3.THE FIRST TIMES EXHAUST STAGE(Fig.5.3-6)
When the pressure inside the chamber reachs 1.100bar,the control system will open the exhaust-solenoid valve(Ev1) for exhausting untill pressure
downs to P=0.000bar.LCD shows

time countdown.
5.3.1.4.THE SECOND TIMES PRE-VACUUM STAGE(Fig.5.3-7)
When the pressure inside the chamber downs to 0.000bar,the control system will open the vacuum pump-solenoid valve(Ev4) and start evacuating.
