前言从瑞典SRM公司引进技术以来,闩本的制冷用螺杆压缩机已有近20年的历史,并在中、大型容量范围的制冷用压缩机中占据牢固的地位。事实上,螺杆压缩机在较大容量范围内,具有良好的特性,它的应用填补了往复式与离心式中间容量范围的空白。目前,在大多数情况下,螺杆压缩机仍被视为一种典型的机种。 Introduction Since the introduction of technology from Sweden’s SRM Corporation, Robben has been developing refrigeration screw compressors for nearly 20 years and has secured a solid position in refrigeration compressors of medium and large capacity. In fact, screw compressors have good characteristics over a large capacity range and its application fills the gap between reciprocating and centrifugal intermediate capacity ranges. At present, in most cases, screw compressors are still considered as a typical model.
