全民企业布拉格CKD厂近年来在掌握新型对动系列的气体压缩机方面进行了很多工作。制订了参数系列,而某一系列压缩机的活塞力则为该参数系列的决定参数。每个系列都是根据两种活塞行程及两种转速来计算的。 在小活塞行程和额定转速下,活塞平均速度近似等于4.5米/秒。大的活塞行程和低转速相配合则保证了活塞平均速度在3.3-4.3米/秒之内。具有这种活塞速度的压缩机用以压缩比重大气体,特别是重碳酸气。若压缩比重小的气体（例如氢气）建议采用大的活塞行程和额定转速相配合的压缩机。在这种情况下平均速度不会超过5米/秒。
The state-owned enterprise CKD plant in Prague has done a lot of work in recent years in grasping the new series of gas compressors. Developed a series of parameters, and a series of compressor piston force is the parameter of the series of decision parameters. Each series is based on two piston stroke and two kinds of speed to calculate. At small piston stroke and rated speed, the average piston speed is approximately equal to 4.5 m / s. Large piston stroke and low speed with the piston to ensure that the average speed of 3.3-4.3 m / s. Compressors with such piston speeds are used to compress heavy specific gravity gases, especially bicarbonate gas. Compression of small proportion of gas (such as hydrogen) suggested the use of large piston stroke and the rated speed of the compressor match. In this case the average speed will not exceed 5 m / s.
