RP型罗茨粗真空泵
RP型罗茨粗真空泵和RG型罗茨鼓风机均属容积式机械，它是依靠对称8字形的渐开线转子在保持一定间隙等速反向旋转时抽出和输送气体的。
Model RP Roots rough vacuum pump and Model RG Roots blower are belong to positive displacement machinery. They rely on 8-shaped symmetrical involute rotor to keep a certain gap with equal speed in the reverse rotation to extract and tranfer gas.
主要用来抽气、输送空气及其它气（汽）体。例如：高炉鼓风、矿山通风、煤气压送、真空吸送、水蒸汽的压缩升温、化肥行业中氨气压缩等。
They are mainly used to extract gas, transfer air and other gas (stream).Such as:Blast furnace blasting, mine ventilation, gas pressure delivery, vacuum delivery, water vapor compression warming up, ammonia compression chemical fertilizer industry.
