Water temperature control machine temperature advantages:
1. Water temperature mold using water as a heat transfer medium, media clean and pollution-free. Especially suitable for dust-free workshop.
2. Water temperature mold using water as a heat transfer medium, relative to HTF, water heat transfer coefficient is much higher, the heat transfer effect is better than the HTF.
Water temperature control machine temperature shortcomings:
1. Water temperature control machine temperature range generally only at room temperature ~ 180 ℃.
2. Water temperature exceeds 100 ℃ boiling point, the need for additional pressure to make the water temperature reached 100 ~ 180 ℃. When the water temperature reaches 180 ℃, the system maximum pressure will be close to 12kg / cm2. Excessive water pressure is not suitable for some of the pressure capacity of the heating equipment.
3. The specific heat of water is double the heat transfer oil, heating the same mass of heat transfer medium. Water heat is double the heat transfer oil.
4. In cold conditions, the water temperature mold machine for a long time, the pipeline easy to freeze.
Oil temperature control temperature advantages:
1. Oil mold temperature machine using thermal oil as a heat transfer medium, wide temperature range, the temperature range at room temperature ~ 400 ℃.
2. Oil mold temperature machine operating pressure is small, can be at a lower pressure, get a higher heating temperature.
3. Heat transfer oil is smaller than the specific heat of water, heating the same quality of heat transfer medium. HTF heat absorption than water heat absorption is much smaller.
4. Heat-resistant oil-resistant cold, not easy to freeze.
Oiler temperature control temperature shortcomings:
1. Oil mold temperature machine using heat-conducting oil as a heat transfer medium, if there is oil leakage overhaul, it is easy to pollute the workshop.
2. Oil mold temperature machine using heat-conducting oil as heat transfer medium, relative to water, the heat transfer coefficient of heat-conducting oil is small, the heat transfer effect is worse than the heat transfer effect of water.
