油压机充液装置的设计不当,在压机工作时造成充液箱油液满溢,这在生产实践上已发生过多次。充液箱油液满溢的原因很多,但主要的是充液箱回油管的排油能力过小,或充液箱的某些结构参数选择不合理所致。至于如何进行充液装置的设计,目前尚缺乏系统的分析和设计理论依据。为了解决这个问题,本文首先分析充液箱在压机每次工作循环中获得的油液增量,并由此算得需要回油箱满足的最大排油流量,然后推导出仅适用于充液箱回油管这一场合的,按已知流量求回油管管径的通用公式。在这基础上,再从充液箱的工作情况分析出发,总结出充液箱结构参数的制定原则,最
Improper design of the hydraulic filling device, resulting in liquid overflow of the filling tank during the press work, which has occurred several times in production practice. There are many reasons for fluid overflow in the filling tank, but the main problem is that the discharge capacity of the oil return pipe in the filling tank is too small or the selection of some structural parameters of the filling tank is not reasonable. As for how to carry out the design of liquid-filled device, there is still no systematic theoretical basis for analysis and design. In order to solve this problem, this paper first analyzes the incremental amount of oil that the filling tank obtains in each working cycle of the press, and calculates the maximum discharge flow that needs to be returned to the oil tank. Then, Tubular this occasion, according to the known flow to find the general formula of tubing diameter. On this basis, and then from the analysis of the working conditions of the liquid tank, summed up the formulation of the structure parameters of the filling tank, the most
