提高采用环状阀的立往复式真空泵真空度的方法

Methods for Heightening Vacuum of the Vertical Reciprocating Vacuum pump with Ring shaped Valves

本文对采用自动固定气阀（环状阀）的立式往复式真空泵真空度的影响因素进行了理论分析，并介绍了设计ＬＶＰ－１００型立式单缸双作用无油润滑往复式真空泵在提高真空度方面所采取的措施。

The factors influencing the vacuum of the vertical reciprocating vacuum pump with automatic spring loaded, fixed valves (ring shaped valves) are dealt with. The methods for heightening vacuum have been applied in design and making the prototype machine of the LVP 100 vacuum pump which has single cylinder, double acting and lubrication without oil. The result shows that these methods are effective.
