防干烧功能发热管真的耐干烧,缺水也不会烧坏吗?很多电热棒生产厂家和客户沟通时,把加热棒暂时的抗干烧就说成是可以防干烧,以至于客户在使用过程中产生种种疑惑?加热棒厂家明明说电热管有防干烧功能,为什么在水垢附着严重和缺水的情况下,还会烧坏呢?其实,很多加热管在干烧过程中只是暂时的断了一下电源过几分钟待温度稍下降又自动恢复通电开始加热了,频繁动作内置温控器随时烧坏,还会缩短电热管的寿命。

很多设备运行时要求水温水位仪在对水箱加温中的时间和水温是有该水温水位仪控制,所以装有这种功能的水温水位对电加热管要求也不同,电热管无须自带水温控制,但必须带过热保护和防干烧保护功能,这样就有效的在异常情况下得到保护。

要实现异常情况下加热管得到保护这的功能,必须在电热管上内置一种2合1过热保护器,当电热管出现超温或缺水干烧,内置2合1过热保护器快速动作断开电源停止加热,,这种保护器在供给电热管电源的继电器没断开触点前始终不会复位.继电器在停止对电热管供电后该保护器才会复位,也就是电热管在非正常状态中不会出现频繁通电干烧,这样就有效的保护了电热管,有效的防止干烧是延长电热管的首要关键条件。
What is the function of anti-dry heating pipe 防干烧功能发热管? Many electric rod manufacturers and customers to communicate, the temporary anti- dry heating rods are said to be anti-dry, so that customers in the use of all the doubts generated in the process ? Heating rod manufacturers clearly said heating tube with anti -dry function Why serious and water scarcity in the scale attached to the case , but also burn it ?In fact, many heating pipe in the dry process only temporarily cut off the power in a few minutes until the temperature dropped slightly and automatically restores power begins to heat up, frequent movement built thermostat always burned, but also shorten the life of the heater .
Requires a lot of equipment running water heating tank water level meter on the time and temperature of the water level meter is controlled , so the water level is equipped with this feature on the different requirements of electric heating pipe , heating pipe temperature control without built-in , but must be with overheat protection and anti-dry protection, thus effectively protected in exceptional circumstances .
To achieve the exceptional circumstances of the heating pipe to be protected this feature, you must on a built- in heater 2 in 1 overheat protection, over-temperature occurs when the heating pipes or water dry , built-in 2 -in-1 thermal protector off fast action open the power to stop heating , such protection in the power supply relay electric tube did not break contact before always reset the relay after stopping heater power will reset the protector , which is normal in the non- electric tube state does not occur frequently energized dry , so that effective protection of the heating pipes, effectively prevent dry heating pipe is to extend the primary key condition .
