2. Structure Characteristics and Working Principle
2.1 Main Functions
The STM-W series of standard water heater are used to heat up the mould and
maintain this temperature. Besides, they can also be used in other similar
applications. High temperature water from the mould is cooled by direct cooling
and then sent to the pipe heater via high-pressure pump for heating to a
constant temperature. With our optimised design, water can reach a maximum
of 120℃ and the HANYOUNG temperature controller can maintain an accuracy
of ±1℃.
2.1.1 Working Principle
Picture 2-1:STM-W Working Principle
High temperature water returns to the machine and then be pressured by pump
to the heater. After being heated, water will be forced to mould and continue the
circle. In the process, if the water temperature is too high, the system will
activate the solenoid valve to let cooling water cool down the temperature
directly until the water is down to the system requirement. If the temperature
keeps increasing and reach to the set point of EGO, system will sound high
pressure alarm and stop operation; when system pressure is too high (Reach
