介绍了一种新型手动液压机具,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,使机具在不同载荷情况下,自动调整提升速度,轻松操作。并对不同载荷情况下新型机具的速度和不同速度下的承载能力进行了全面的分析,分析结果进一步验证了本新型手动液压机具达到了空载和轻载增速、重载增力的效果。
A new type of manual hydraulic machine is introduced. The simple structure of large and small pump or large and small oil cylinder is creatively used to synchronize the output of large and small oil cylinders and synchronously reset, so that the machine can automatically adjust the lifting speed under different load conditions. operating. The new machine tools under different loading conditions are analyzed in terms of speed and carrying capacity at different speeds. The results further verify the effectiveness of the new manual hydraulic machine in no-load, light-load and heavy-load boosting.
