A, principle, properties and USES
Principle performance: is when the temperature of the controlled object changes make the thermostat temperature area of the working medium produces the corresponding heat bilges cold shrink physical phenomena (medium volume change), and the heat of connected with bellows expansion or contraction. Through the lever principle, drive switch on-off action, to achieve a constant temperature. WK series liquid bulge thermostat with a temperature control is accurate, stable and reliable, open stop temperature difference is small, the temperature control is the adjusting range is large and overload current big etc. Characteristics.
USES: mainly used in household appliances industry (shower, drum washing machine, heater, electric heating equipment (automatic water boiler, embedded electric oven, stainless steel electric fryer), food machinery, medical equipment, refrigeration industry (kitchen freezers, fresh cabinet, refrigerator, ice machine, fish pond, cold drink machine, heating machine), such as temperature control.
Second, the technical parameters:
1, electrical performance, 16 (3) A – 250 – v ~ 10 ~ (1.8) A – 400 v
2, disconnect the temperature: according to the user’s requirements, design temperature range (- 35 ℃ ~ + 320 ℃)
3, product life: > 100000 times
4, electric strength: AC2000V / 1 min
5, normal insulation resistance: 100 m Ω or higher
6, contact resistance: Ω 50 m or less
7, tide insulation resistance: 10 m or more Ω
8, temperature response rate: 1.0 ℃ / min or less
9, the minimum current: 200 ma
Three, matters needing attention:
1, the user must be based on the characteristics of their products, the required temperature control, put forward the order type and specification.
2, the thermostat installation, heat pipe as far as possible the whole stick close by surface temperature control, in order to achieve the purpose of accurate temperature control.
3, when installation may not be heat pipe pressure deformation, lest affect its performance.
4, don’t make the conductive gas or conductive material so as not to affect the surface of the thermostat or pollution thermostat electric insulation performance.
5, mounting bracket M4 machine wire don’t too long, otherwise it will damage the thermostat performance.
6, switch box is electric ceramic to should take put down gently, to avoid damage.
7, capillary bending radius not less than 5 mm.
Four commonly used temperature range
35 ℃ + 0 ~ 30 ~ 40 ℃ 75 ℃
30 ~ 85 30 ~ 30 ℃ ~ 90 ℃ 90 ℃
50 ~ 60 ~ 200 ℃, 250 ℃, 50 ~ 300 ℃
50 ~ 320 ℃
