[摘要]：在国顾国内单爆杆压缩机曲新发展的深度原因后指出，近20年来国内市场上单螺杆产品采用的啮合型线基本承袭了国外沿用的原始技术，产品使用中诸多“星轮故障”使得当今的单螺杆产品在市场上跌到了谷底；介绍了最新发展的单螺杆喷液悬浮合技术，以及保障星轮齿及轴承永远免受损毁的专有技术。这些技术确保单螺杆回归到“理想压缩机”，实验和应用结果已给出全面证明。

Abstract:ln this paper, the reasons why domestic single screw compressors developed tortuously were reviewed. It indicates in the recent 20 years, the mashing profile on the domestic market of single screw products mainly follows the original technology used abroad. However, numerous "star wheel failure" problems push the single screw compresors' market to the bottom. The new devel-opment of the single screw suspended meshing technology, as well as the proprietary technology that protecting the star-wheel teeth and the bearings out of destruction through the whole operation life. The techniques ensure that the single screw compressor can re-store to the "ideal compressor", for which, the testing and applications results have been given a full proof.

1引信言
单螺杆压缩机在理论上是一种十分完美的气体压缩机械。主要在于它体积小，重量轻，振动噪声小，新制机器在刚投人运行的一段时间内容积效率高，泄漏少，同等级制造精度下的比能耗明显小于其他螺杆或滑片压缩机。文献[1]价绍了2009年国家工信部列出的机械产品节能目录中，空压机行业共有11个型号产品列人其中，其中11个型号产品全部是单螺杆空压机，而当时的单螺杆空压机产品仅占全国回转式空压机年产量的5%以下。

螺杆空压机都属于单直线（圆柱）啮合的传统产品，绝大多数机器在投人运行一两年后，流量就明显下降达10%以上。同时，也常有不少机器出现轴承异常损毁审动和星轮擦伤断裂等现象，甚至发生机壳侧窗被星轮撞裂的事故（图1）。致使单螺杆空压机近年来声誉大跌，有不少单螺杆制造商减产或停业，或转向经营双螺杆及其他产品。有不少制造商的产品销售广告把单螺杆压缩机的“单，字去掉，以回避众人之嫌。为此，我们不得不对十几年来单螺杆压缩机在我国的发展过程进行反思。
