速度型压缩机——是回转式连续气流压缩机，在其中高速旋转的叶片使通过它的气体加速，从而将速度能转化为压力。这种转化部分发生在旋转叶片上，部分发生在固定的扩压器或回流器挡板上。
Speed type compressor is a rotary continuous flow compressor in which the high-speed rotating blades accelerate the gas passing through it, thus converting the speed into pressure. This conversion occurs partly on the rotating blade and partly on the fixed diffuser or reflux baffle.
离心式压缩机——属速度型压缩机，在其中有一个或多个旋转叶轮（叶片通常在侧面）使气体加速。主气流是径向的。
Centrifugal compressor-a speed type compressor in which one or more rotating impellers (usually on the side) accelerate the gas. The main flow is radial.
轴流式压缩机——属速度型压缩机，在其中气体由装有叶片的转子加速。主气流是轴向的。
Axial compressor is a speed type compressor in which the gas is accelerated by a rotor equipped with blades. The main flow is axial.
混合流式压缩机——也属速度型压缩机。其转子的形状结合了离心式和轴流式两者的一些特点。
Mixed flow compressor - also speed type compressor. The shape of the rotor combines some characteristics of centrifugal and axial flow.
喷射式压缩机——利用高速气体或蒸汽喷射流带走吸入的气体，然后在扩压器上将混合气体的速度转化为压力。
Jet compressor - the use of high-speed gas or steam jet stream to take away the inhaled gas, and then convert the speed of mixed gas into pressure in the diffuser.
永磁变频压缩机——由于变频化的螺杆空压机利用了变频器的无级调速特点，通过控制器或变频器内部的PID调节器，能平缓启动；对用气量波动比较大的场合，又能快速调节响应。
Permanent magnet variable frequency compressor: because the variable frequency screw air compressor makes use of the stepless speed regulation characteristics of the frequency converter, it can start smoothly through the controller or the PID regulator inside the frequency converter, and can quickly adjust and respond to the situation with large fluctuation of air consumption.
