基于负载敏感多路阀的旋压机液压系统设计

摘要

介绍了旋压机的工作原理，在对旋压机液压系统存在的主要问题进行分析的基础上，设计了新的液压系统，该系统采用变量泵和负载敏感多路阀，实现了旋压机的无级变速，减少了液压系统的压力损失，降低了液压元件的分散程度及系统油温和噪声，使系统能量得到了最有效的利用，提高了工作效率。%Based on the introduction of the working principle of spinning machine and analysis for hydraulic sys -tem of spinning machine , it designs a kind of hydraulic system of spinning machine with variable pump and load sensitive multi-way valve , realizes the infinitely variable speed of the pulley spinning machine , decreases the pressure loss of hydraulic system and the dispersion of hydraulic components .This hydraulic system reduces the pressure of oil and noise , improves the use of system energy in a more effective way and working efficiency .
