The Stability Of KSD Thermostat Temperature Switch
KSD thermostat temperature switch have the advantages of high accuracy, small size, long life, good vibration resistance, etc., and can be widely used in electric heating appliances and electric appliances in the field of household appliances, and they are increasingly showing broader application prospects. KSD thermostat temperature switch is the main component of temperature control, overheat protection, temperature display and over-temperature alarm, and its temperature stability is one of the most important technical indicators.
KSD thermostat temperature switchs are generally closed, consisting of thermal bimetallic components, linkage mechanism, contact assembly, housing and other main components. It is different from slow-acting or quick-acting thermostats in that the hot bimetal is pre-processed into disc-shaped discs. During the temperature change cycle, the disc does not continuously change its curvature, but is flat. The two stable positions that are symmetrical in the straight state jump suddenly. The two contacts are quickly opened or closed through the linkage mechanism. How to ensure that the thermal bimetal produces a sudden jump at the rated temperature value, and it is very important to ensure its temperature stability from the internal quality.
In the manufacturing process, generally according to the deflection that may be formed by the temperature rise, the hot bimetallic disc of the snap-type thermostat is processed into an arch shape. Relatively speaking, the large arch-shaped wafer has a higher temperature value.
