Principle, performance and Application
Principle performanceWhen the temperature of the controlled object changes, the working substance in the temperature sensing part of the temperature controller generates the corresponding physical phenomenon of expansion and contraction (the volume change of the working substance), and the bellows which are connected with the temperature sensing part produce expansion or contraction. Through the lever principle, drive switch on-off action, to achieve the purpose of constant temperature.WGASeries liquid expansion thermostat has the characteristics of accurate temperature control, stable and reliable, small open and stop temperature difference, large temperature control range, high overload current and so on.
When the 1: temperature reaches the required control temperature, it will automatically cut off the power supply (using electrical appliances to stop working), and when the temperature is lower, it will automatically switch on the power supply (starting with electrical appliances);
2: when the temperature rises, it will automatically switch on the power supply, when the temperature drops to the required control temperature, it will automatically cut off the power supply"
purposeIt is mainly used inAppliance industry(shower, drum washing machine, warm air machine),Electrothermal equipment(stainless steel automatic water heater, electric fryer, food machinery, medical equipment),Refrigeration industryThe temperature control is used in the kitchen, freezer, fresh keeping cabinet, cold storage, ice maker, fish pond, cold drink machine, central heating machine, etc..
