本文概述了SY 350-ⅡA型液压碎石器的工作原理,对其筒阀配流冲击机构作了分析,并对工作油温对油液粘度、筒阀配合间隙的选择及缝隙流量的影响作了分析比较,还对液压碎石器的冲击功、冲击频率、换向孔位的确定及隔膜式蓄能器等主要参数的设计计算也作了一些探索,并提出了冲击频率的调试方法。一、结构原理液压碎石器主要用于各种破碎作业。按取得冲击功的方式碎石器可分两类:一类是高压油通入冲锤的前腔,冲锤在油压的作用下向后
This paper summarizes the working principle of the SY 350-ⅡA hydraulic stone crusher and analyzes the impact mechanism of the cylinder valve with the impact of the working oil temperature on the viscosity of the oil, the gap between the valve with the choice and the impact of the gap flow Analysis and comparison are also made on the design and calculation of the impact energy, impact frequency, reversing hole location and the main parameters of hydraulic accumulator, such as hydraulic impact device. First, the structural principle Hydraulic crusher is mainly used for a variety of crushing operations. According to the way to obtain impact energy stone devices can be divided into two categories: one is the introduction of high-pressure oil into the hammer before the cavity, the hammer under the hydraulic pressure back
