多速手动液压千斤顶的速度分析

Analysis of Speed for a New Type of Manual Multilevel Hydraulic Jack

介绍了一种新型手动液压千斤顶,创造性地采用大、小泵或大、小油缸于一体的简单结构,使大小油缸同步出力、同步复位,使千斤顶在不同载荷情况下,自动调换提升速度,操作轻松。对不同载荷情况下新型千斤顶的速度进行了全面的分析,进一步验证了本新型手动液压千斤顶具有空载和轻载增速、重载增力的优点。

A new type of hydraulic pressure clamp is introduced in this paper. In this type of clamp, a big bump, a small bump, a big oil jar and a small oil jar is made together in a part, the big bump and small bump can work and replace together. It can. adjust speed automatically according different forces and be operated easily. Speeds at different load are analyzed, the analysis results proved that this new manual hydraulic pressure clamp has advantages of high speed in the situation without load or small load and slow speed in the situation with large load.
