摘要:车间风动工具的使用使繁重的手工操作实现机械化，减少了工人的工作强度，增加了工厂的工作效率，缩短了工作周期。由于风动工具具有轻小、高效及安全可靠的特点，所以目前在各个大型工厂都具有风动工具系统。
根据要求对风动工具系统进行设计，计算出所有风动工具的耗气量，选择风动工具工作压力，计算出储气罐的体积，最低压力值和最高压力值，并实现自动控制原理，储气罐压力低于最低压力值时启动电动机，高于最高压力值时停止电动机。油水分离器和干燥器是气体净化中两个重要的装置，对其进行结构设计、参数设计，绘制出油水分离器和干燥器的装配图及其重要零件图。对于其他装置，根据对其的性能要求，在市场上选择购买。

ABSTRACT:The use of workshop pneumatic tools make burdensome handwork mechanization, reduces the work intensity of workers, increases the efficiency of the plant, shortens working period. Because the pneumatic tool has the characteristics of small, high efficient and safe, so in each large factories has pneumatic tool system in the current.
According to the requirements of the design of the pneumatic tool system, calculate the consumption of all pneumatic tool, select the pneumatic tools work pressure, calculate the reservoir volume, minimum pressure and maximum pressure value, and the realization of the principle of automatic control, when air storage tank pressure is lower than the minimum pressure to start the motor, and is higher than the highest value of pressure to stop the motor. Oil-water separator and dryer are two important device for purifying gas, carried on the structure design, parameter design, draw the assembly drawing of oil-water separator and dryer and its important parts diagram. For other devices, according to the requirements of its performance, in the market to buy.

风动工具系统由三大部分组成，气源发生装置、气体净化装置和气动工具。
气源发生装置是由电动机和压缩机组成，电动机带动压缩机吸入空气并将空气压缩排送出去；气体净化装置由后冷却器、油水分离器、干燥器、过滤器和储气罐组成，压缩空气经后冷却器降温后，气体终的水分、油滴和灰尘凝结出来，然后传输到油水分离器分离，对压缩气体进行第一步净化，压缩空气流入到干燥器内再进行一次干燥除水，然后流经过滤器进行精过滤，最后流入到储气罐进行储存；当风动工具工作的时候，储气罐中的压缩气体经减压阀控制压力，再由油雾器对空气中加入雾态润滑油，最终带动风动工具转动。
