tronics technologies, creating the necessary devices with low power consumption, programmable logic controller as a directdrive ponents, plex largescale process control, to give a good energy saving effect. (3) development of energysaving pneumatic ponents pneumatic energy development ponent, available from the following aspects: to reduce leakage, reduce energy of antileakage, good wear resistance, no to oil seals soft of lowpower pneumatic ponents, reduce energy the oil lubrication, oil consumption to reduce environmental to oil lubrication system is a pneumatic filter, regulator why not lubricating the valves, cylinder ponent pneumatic system to the oil used in the work of the medium the air does not contain oil mist, emissions are also nonoil ponents to the oilfree lubrication is a preinjection of grease in the device can work long hours without added grease in the pneumatic pneumatic system to the oil mist from time to set up system to the oilfree lubrication is simple, low cost, easy maintenance, foreign equipment monly used by this the course of such a system is essentially the same lubrication conditions, changes in external conditions are not subject to interference, and thus stable performance, long lubrication lubricationfree pneumatic cylinder system is a special structure, and use a selflubricating material ponents, materials and manufacturing difficulties due, it is now also applied. (4) rational design of pneumatic systems, merit selection and rational use of pneumatic ponents, pneumatic fluid to reduce gas consumption, pneumatic system dynamics theory and experimentation, the use of puter simulation technology to optimize the design of the pneumatic system, merit selectionbest example, the nominal diameter of the cylinder is based on mon ratio of geometric progression of points files, such as the expansion of the cylinder diam
