一种3MCL小型压缩机风筒布置结构
摘要：
本实用新型涉及压缩机部件，具体地说是一种3MCL小型压缩机的风筒布置结构，该压缩机上安装有一段进风筒、一段出风筒、二段进风筒、二段出风筒、三段进风筒及三段出风筒，所述一段进风筒、一段出风筒、三段进风筒及三段出风筒的风筒法兰的内圆分别与所连通的窝室一侧内壁相切。本实用新型将常规窝室中心与风筒法兰中心共线的方式改为窝室一侧与风筒法兰内圆相切的布置方式，在风筒大小不变，转子总长不变的前提下，使风筒的布置问题得到解决，既满足了性能的要求又满足了结构上的要求。
摘要（英）：

The utility model relates to a compressor part, in particular to an air duct arrangement structure of a 3MCL miniature compressor. A one-section air inlet drum, a one-section air outlet duct, a two-section air inlet drum, a two-section air outlet duct, a three-section air outlet duct and a three-section air outlet duct are arranged on the compressor, wherein and the inner circles of air duct flanges of the one-section air inlet duct, the one-section air outlet duct, the three-section air outlet duct and the three-section air outlet duct are respectively tangent with the inner wall of one side of a nest chamber communicated with the one-section air inlet duct, the one-section air outlet duct, the three-section air outlet duct and the three-section air outlet duct. As the conventional mode that the centers of the nest chamber is in collineation with the air duct flanges is changed to the arrangement mode that one side of the nest chamber is tangent with the inner circles of the air duct flanges, the air duct arrangement structure of the 3MCL miniature compressor solves the arrangement problem of the air duct without changing the sizes of the air duct and the total length of a rotor, thereby meeting the requirement on performance as well as the requirement on the structure.
