推送缸油路是混凝土泵的主要工作油路。本文对此油路进行了动态分析,并提出了设计选择推送缸油路主要参数的方法,即为了提高混凝土泵的效率,减少能量消耗,在设计时尽量减小系统压力阻尼比和液压缸活塞面积,提高系统工作压力,使系统压力固有频率和混凝土泵的工作频率相等。 The push cylinder circuit is the main working circuit of the concrete pump. This article has carried on the dynamic analysis to this oil route, and put forward the method of designing and choosing the main parameters of the push cylinder oilway, namely, in order to improve the efficiency of the concrete pump, reduce the energy consumption, try hard to reduce the systematic pressure damping ratio and hydraulic cylinder piston while designing Area, increase system work pressure, make the natural frequency of the system pressure and the concrete pump work frequency equal.
