目前，大多数企业生产的油压机都较好地解决了工作吨位大但重量轻、能耗低的问题，但在保证动作可靠前提下提高效率方面大都不尽人意。本文对油缸结构和参数选择与提高油压机效率、可靠性的关系方面进行了分析，提出了解决方法。并在实际应用中达到了较好的效果。１上移式... At present, most of the hydraulic presses produced by the enterprises solve the problems of large working tonnage but low weight and low energy consumption, but most of them are unsatisfactory in terms of improving the efficiency under the premise of ensuring the reliable operation. This paper analyzes the relationship between cylinder structure and parameter selection and improving the efficiency and reliability of hydraulic press, and puts forward the solution. And in practical application has achieved good results. 1 move up ...
