PV-120旋片式真空泵主要参数和尺寸的确定

Study on the Parameters and Size of PV-120 Rotary-vane Vacuum Pump

我国挤奶机近几年来主要由引进国外产品逐渐发展成部分零部件国产化,特别是小型挤奶机现在基本上可以达到整机国产化。为了更好地从理论上深入,使挤奶机走向国产化,论述了作为小型挤奶机核心部件的PV-120旋片式真空泵,提出了旋片式真空泵主要参数和尺寸的设计程序与公式。

In recent years, the milking machine, which mainly has been imported from abroad before, has gradually developed to be made in China partly, especially the small, For upgrading the machine better in theory to make it made in China, this paper states the key components of the small, milking machine, PV-120 rotary-vane vacuum pump, and puts forward the design program and formulas of the main parameters and sizes of rotary-vane vacuum pump.
