文档介绍：往复活塞式压缩机
摘要
现代企业中,使用压缩气体的机器越来越多,例如:石油、化工、冶金、轻工、纺织、采矿等,许多工业中无不广泛使用各种各类的气体压缩机。因此,气体压缩机是近代工业生产中不可缺少的通用机器。结合所了解的中、小型压缩机,了解其基本结构及其工作原理,重点掌握其结构设计,学会所含零部件的结构设计方法及其强度校核方法,在设计过程中,理论联系实际,最终了解设计一个设备的基本思路和方法。
W型活塞式级差压缩机主要应用于船舶中气体压缩,虽然其结构有别于其它压缩机,但他们的原理相似。因此可以根据已知的压缩机类型,通过互相比较,进而进行设计。
整个设计过程包括总体结构设计、热力学的计算、初定相关零部件的机构尺寸,然后借助AUTOCAD等绘图软件绘图,选定轴承等标准件,应用强度理论对其进行必要的强度校核以满足实际的需要,最后确定压缩机的辅助设备。
此往复式压缩机适用压力范围广。因依靠容积变化的原理工作,因而不论其流量大小,都能达到很高的工作压力。目前已制成低、中、高、超高压各种压缩机,其中工业上超高压压缩机的工作压力可达350MPa(3500kgf/cm2)。

RECIPROCATING PRESSOR
ABSTRACT
In modern enterprises, the use pressed gas machine more and more, such as petroleum, chemical industry, metallurgy, light industry, textile, mining, etc., is widely used in many industrial all kinds of various pressor. Therefore, pressor is indispensable in the modern industrial production of general machinery. Medium and small understanding of bination pressors, understand its basic structure and working principle, the key to master the structure design, learn to ponents structural design method and its strength check method, in the process of design, theory with practice, eventually understand design a device's basic ideas and methods.
W-shaped rebound in the piston, pressor is mainly used in ships in the pression, although its structure is different from the pressor, but the principle is similar. So you can according to the known pressor, through parison with each other, and then to carry on the design.
The entire design process including the design of overall structure, thermodynamic calculation, the initial relative parts of body size, and then with the help of AUTOCAD drawing software such as drawing, selected bearings, standard parts, the strength theory to make the necessary intensity to meet the actual needs, finally determine pressor of the auxiliary equipment.
Thus pressor is pressure range. By relying on the principle of volume change work, thus flow regardless of their size, can achieve very high work
