对于恒功率电伴热带来说,温控器能够控制电伴热带温度
在电伴热系统中,经常会用到温度控制器。对于自限温电伴热带来说,可根据环境自动调节温度,通常情况下是不需要安装温度控制器的,但在温度控制精度要求较高的情况下,就需要加装温度控制器。
In electric heat tracing system, temperature controller is often used.
For the self limiting electric tracing band, the temperature can be
adjusted automatically according to the environment. Generally, there is
no need to install a temperature controller, but in the case of high
temperature control accuracy requirements, it is necessary to install a
temperature controller.
对于恒功率电伴热带来说,温控器能够控制电伴热带温度,而且可以精确的调节温度。如果没有温度控制器,被伴热体达到要求的温度,恒功率电伴热带还会继续放热,造成热能的浪费,管内温度过高会导致管内介质发生化学或物理反应。
For the constant power electric tracing band, the temperature controller
can control the temperature of the electric tracing band and adjust the
temperature accurately. If there is no temperature controller and the
heat tracing body reaches the required temperature, the constant power
electric tracing belt will continue to heat, resulting in the waste of
heat energy, and the high temperature in the pipe will cause the
chemical or physical reaction of the medium in the pipe.
控制器的使用,需要在储罐、管道和电伴热带之间安装温度传感器。温控器温度传感器的感温探头应放置在管道顶部的最低温度点,紧贴管道或储罐的外壁,然后用铝箔胶带或压敏胶带固定。温度传感器的安装位置离电伴热系统太近或太远,产生的温度值会影响系统的温度控制。
For the use of the controller, it is necessary to install a temperature
sensor between the storage tank, pipeline and the electric tracing band.
The temperature sensing probe of the temperature sensor of the
thermostat shall be placed at the lowest temperature point on the top of
the pipeline, close to the outer wall of the pipeline or storage tank,
and then fixed with aluminum foil tape or pressure-sensitive tape. The
installation position of the temperature sensor is too close or too far
away from the electric heat tracing system, and the generated
temperature value will affect the temperature control of the system.
如何安装温度控制器呢?首先温度传感器不应安装在与电伴热带直接相连的临近区域;在者温度传感器应安装在阀门、法兰、泵和支架之间至少2米的间距;最后安装温度传感器时,应遵循相关的安装说明。
How to install the temperature controller? Firstly, the temperature
sensor shall not be installed in the adjacent area directly connected
with the electric tracing belt; secondly, the temperature sensor shall
be installed at least 2m between the valve, flange, pump and bracket;
finally, the relevant installation instructions shall be followed when
installing the temperature sensor.
