壳管热交换器（也称为管和管热交换器），壳管热交换器主要由壳，管束，管板和头部组成。外壳大部分是圆形的，内部有一个平行管束。或螺旋管，其末端固定在管板上。在壳管热交换器中交换热量的两种流体，一种流动在管中，中风称为管路径。另一个在管外流，行程称为壳侧。管束的壁表面是传热表面。管和管热交管具有不同的模型。该过程通常是三个模型，直径为16mm，20mm或25mm。壁厚通常为1mm，1.5mm，2mm和2.5mm。导入的热交换器的直径为8mm，壁厚仅为0.6mm。 The heat exchange efficiency has been greatly improved, and it has been gradually promoted in the domestic market this year. The shell-and-tube heat exchanger and the spiral tube bundle design can increase the turbulence effect to a limit and increase the heat exchange efficiency. The asymmetrical design of the inner shell and tube layers can reach 4.6 times. This asymmetric design determines its wide application in the field of vapor-water heat transfer. The heat exchange efficiency can reach 14000w/m2.k, which greatly improves production efficiency and saves costs. At the same time, because the shell-and-tube heat exchangers are mostly metal structures, with the introduction of the new GMP in China, the stainless steel 316L is the main heat exchanger, which will become a must for the beverage, food, and pharmaceutical industries.

壳和管热交换器的安装注意

1.各种阀门和仪器的安装高度应易于操作和观察。

2.壳管热交换器的前端应具有泵送和卸载管束的空间，即壳和屋顶之间的距离不应小于热交换器的长度，设备操作和操作通道的净宽度不应小于0.8m。

3.壳体热交换器上部（通常称为安全阀）到建筑物结构的低点的垂直清除应满足安装和检查的要求，并且不得小于0.2m。

4.热交换器应以工作压力的1.5倍进行液压测试。蒸汽部分不得低于蒸汽供应压力加0.3 MPa；热水部分不得低于0.4 MPa。在测试压力下，不得在10分钟内保持压力。降低。

壳管热交换器制造商广州总结了上述内容，用于引入壳管热交换器，包括管，壳，型号和应用，是壳管热交换器的安装注意事项不能忽略，请注意安装注意力。此事是完全合理地使用管热交换器的良好开始。
