3. Main Functions
High-temperature water returning from mould returns to cooler through pipes,
which is conveyed to heater after being pressured through pumping and it is
transmitted to mould after being heated in electric thermal pipe, so on and so
forth. In this process, when liquid level switch detects that liquid level falls
down to set value, the water replenishing electromagnetic valve is started,
which replenishes water to ensure normal operation of the system; If the
water temperature is too high, the system will start up cooling electromagnetic
valve and cooled water will enter the system to cool water at high temperature
indirectly and reduce its temperature, by which the purpose of maintaining
constant temperature is achieved. If water is still at high temperature and
maintains at the level of the set EGO temperature, system will start up high
temperature alarm and stops working; When system pressure arrives at set
value of safety valve, safety valve is started and starts releasing pressure; If
system pressure keeps rising, which is higher than the set value of pressure
switch 2, system will start up water replenishing electromagnetic valve to
release valve; if the pressure of cooled water fails to reach the preset
requirements, pressure switch 1 will emit signal, system starts up
low-pressure alarm and stops working.
