因为燃料经常涨价,(并且可能得到的燃料很可能继续减少)因此,在气动系统的设计和元件选择中,把最适宜的能耗计入制造成本乃是一个重点考虑的问题。但是重要的是记住其他优先条件可能大大地影响系统设计者最终选择的元件和工作压力。 Because of the frequent fuel price increases (and the likely reduction in fuel that may be obtained), it is a key consideration to include the most appropriate energy costs in manufacturing costs for the design of pneumatic systems and component selection. However, it is important to remember that other prerequisites can greatly affect the final choice of components and work pressure by the system designer.
