STM-PW Working Principle
The high temperature water from the mold returns to the pump inlet from the
pipeline, then be pressurized by the pump and conveyed to the heater and
again be heated and returns to the mold. The loop repeats. In this process,
when liquid level switch detects the liquid level lowers to the set value and the
machine will sound an alarm and halt. If the temperature of the water exceeds
the set value, the system will automatically start the solenoid valve to let the
cooling water come into the double pipes structure of the heating tank and cool
down the water, then a constant temperature can be maintained. If the
temperature still maintains high to the EGO set value,the system will sound an
alarm and halt; when system pressure exceeds set valvue of high pressure
switch, machine halts and sound an alarm. If the pressure continues rising to
the set value of the safety valve, the safety valve starts to decompress the
system.
