| 加热棒，是用来提高水温的一种工具，市面上普遍流行的加热棒有两种，一种直接用双金属片控温，另一种则采用热敏电阻探测温度，用可控硅等来控制加热棒的通断。加热棒的寿命：普通加热棒建议一般用个两年最好就换了，因为他内部的双金属片时间用久了，容易发生失灵的事情，毕竟又不是很贵的东西，换一个自己心里也踏实些，免得发生一些不必要的损失。 Heating rod is a kind of tool used to improve the water temperature. There are two kinds of heating rods popular on the market. One is directly controlled by bimetal sheet, the other is detected by thermistor, and controlled by thyristor. Service life of heating rod: it is recommended to replace the ordinary heating rod within two years, because the bimetallic sheet inside it has been used for a long time, and it is easy to fail. After all, it's not very expensive. It's more practical to replace it with a new one, so as to avoid unnecessary loss. |
