Analysis and Compare on Hydraulic Automatic Reversing Mechanisms

Several kinds of hydraulic automatic reversing mechanisms,such as mechanical-pilot,mechanical-electric,pilot and electric automatic reversing mechanism were introduced.Through analyzing and comparing on their principles,the advantages,disadvantages,and applications for different hydraulic automatic reversing mechanisms were given.The principle of the mechanical-pilot reversing mechanisms is very simple,but with components dispersed and bad reliability.Pilot reversing mechanisms are comparatively complicated,but compact.They have quite high reversing frequency and good reliability.Both priciple and makeup of electric reversing mechanisms are simple,but these reversing mechanisms can be only applied to the low power system,without explosion-proof requirement.
