发泡机就是能将发泡剂一定浓度的水溶液制成泡沫设备.发泡剂本身是不能自动成为泡沫的,它必须通过发泡机的机械作用才能成为泡沫。发泡机和发泡剂是相互配合的一个技术体系，不能单独发挥作用。发泡机本身是不能凭空产出泡沫来的，它是将空气引入发泡剂水溶液中均匀分散，实现液气尽可能大的接触面，以使发泡剂中的表面活性物在液膜表面形成双电层并包围空气，形成一个个气泡。泡沫混凝土的主体是泡沫，因而制泡沫的发泡机就成了泡沫混凝土生产的关键设备和主机。

(3) 采用高频整流电路，改善整流波形，提高功率因数，直流电压可调节;
(4) 逆变环节采用高开关频率高的电力电子器件，如MOSFET，IG等，可以提高载波频率比，变频器输出端的高频谐波。
(5) 在逆变环节采用多重化技术，提高脉波数，使输出的电流电压波形更加接近正弦波。但重数越多电路越复杂，可靠性会随之降低，三重化电路可以兼顾输出波形质量和设备可靠性，较理想。
2. 采用合适的控制策略
从变频器控制器这一点出发，可采用更合适的控制策略或者在原来的控制策略基础上作点优化和改进，原理上更大限度地减少谐波的产生。以实际应用中常用的正弦脉宽调制法(SPWM)法和特定消谐法(SHE)法为例。

如C63床头箱里发出轰隆轰隆的响声，但不知是哪个轴发生故障。可以依次接通床头箱各轴，当发出的声响与故障异声相似时，即可确定是哪根轴的问题。此方法可诊断轴、齿轮、离合器等零件的故障。条件变化法当机床故障症状不明显、不充分或无规律时，常采用这种方法。如变换机床所受的力，变换机床动作条件、环境条件等。有时还需要附加一些条件进行强制性试验，让故障的症状暴露得更充分些。如：在车床上加工零件时，工件产生振动。
