卧式压缩机装配调试中若干问题的探讨

Discussion on Some Problems in Assemblig and Adjusting Honrizontal Compressor

本文对如何保持卧式压缩机活塞杆中心线与气缸中心线平行,如何合理选择卧式压缩机曲柄转向作了理论上的探讨,提出与以往有所不同的观点:(1)要保证活塞杆中心线与气缸中心线相平行,滑履中心线必须高于十字头体中心线一个微量尺寸δ(2)气缸处于主轴承左侧时,曲柄宜采用逆时针转向;反之,则曲柄宜采用顺时针转向。

This paper discusses, in theory, how to concentre the central line of piston of compressor with the central line of cylinder, and how to choose turning direction of crankshaft of compressor. It gives a new idea relatively different from others. The new idea includes: a. To ensure concentering the central line of piston with the central line of cylinder, the central line of slide shoe must be higher by a very small amountδthan that of cross head. b. When cylinder is located left side of the main bearing, the crankshaft had better turn in anticlockwise direction. Otherwise, the crankshaft had better turn in clockwise direction. Xu Furen
