喷雾干燥机对物料干燥温度的影响：喷雾干燥机作业中，干燥用热风进入塔内的温度（热风温度）与出口温度（排风温度）的决定是很重要的。排风温度与产品的水分含量有关，应按产品容许的水分来决定。热风温度越高热效率越高，经济性越好。但是过高的热风温度会造成产品质量变劣，因此热风温度必须在保证产品质量的前提下适当提高。喷雾干燥机热风温度将对产品的松密度发生明显的影响。高温热风有产生低松密度的倾向，这是由于热风有快速干燥作用，使颗粒表面硬化并使残留湿气膨胀，而促进了气球状中空颗粒的形成。

不知大家是否知道自力式压差控制阀不能代替流量控制阀，它的作用是很重要的，所以大家在选择自力式调节阀时还是要非常慎重的，选择合适的型号才是重要的，今天水力控制阀主要和大家介绍的是自力式调节阀选型常识使用自力式压差控制阀的目的是使热用户能够在一定范围内根据用热需要调节流量，使用沃中自力式压差控制阀的供热系统是一个变流量系统。但目前多数供热管网是根据供暖的基本需要确定的，管网系统实际很难做到按需无限制供热，势必造成管网系统水力失调，特别是在只安装压差控制阀而未装热表的供热系统中，水力失调现象尤为严重。

在无贮液器的装置中，由于系统中制冷剂数量的多少直接决定着冷凝器中制冷剂液位的高低，并因此而影响冷凝器的工作和液体制冷剂的过冷度，所以当系统中的制冷剂量不足时，就必然要引起装置工况的如下变化：压缩机运转不停，但库温降不下来;压缩机的排出压力下降;压缩机的吸人压力较低，吸气过热度，蒸发器后部的结霜融化，压缩机缸头发热;供液液体指示器中可看到液流有大量气泡;冷凝器中的液位明显偏低。
