在高压大流量的间歇负载或大小不等的连续负载系统中,有时一个工作循环内各阶段需要的流量差别很大,而峰值流量负载的时间又往往较为短促,对于这种工况,采用蓄能器作为辅助能源很有必要。在系统工作过程中,皮囊的体积随着充油而压缩减小,随着排油而膨胀增大,蓄能器的工作压力也随之上升、下降。最高工作压力下的油量和最低工作压力下的油量之差,就称为蓄能器的工作容积。确定工作容积是需要认真对待的。因为,在既定工作循环中,系统的平均耗油
In high-pressure high-flow intermittent load or continuous load system with different sizes, the flow rate required in each phase of a work cycle may vary greatly from time to time, and the load of peak flow is often short. For this operation, Anaerobic energy source is necessary. In the process of system work, the volume of the bladder decreases as the oil is filled and expands, and as the oil discharge expands, the working pressure of the accumulator also increases and decreases. The difference between the amount of oil under the maximum working pressure and the amount of oil under the minimum working pressure is called the working volume of the accumulator. Determine the volume of work is to be taken seriously. Because, in a given work cycle, the system’s average fuel consumption
