目前,国产排气压力为7kg/cm~2的动力用移动式单边不对称摆线形线螺杆压缩机,已取得了比功率为6.28KW·min/m~3的良好成绩,淘汰了对称圆弧形线螺杆压缩机。能不能在我国现有设计水平与制造水平的基础上,通过结构的改进,设计一种新的螺杆压缩机,使比功率进一步降低呢?我们认为是可以的。本文想从概念上对此问题作一分析,并提出改进结构的原则建议。单边不对称摆线形线,轴向气密性和横向气密性都是良好的,无懈可击。但是,由于背
At present, the domestic displacement pressure of 7kg / cm ~ 2 power with mobile unilateral asymmetric cycloidal screw compressor, has achieved a specific power of 6.28KW · min / m ~ 3 good results, out of the symmetrical circle Arc line screw compressor. Can we design a new type of screw compressor on the basis of the existing design level and manufacturing level in our country and make the specific power further reduce? We think it is possible. This article intends to make an analysis of the issue from the conceptual point of view, and proposes the principles and recommendations for improving the structure. Unilateral asymmetric cycloidal line, the axial air tightness and horizontal air tightness are good, impeccable. However, due to back
