摘　　要：压力机是一种结构精巧的通用性压力机。普通的压力机具有通用性,速度,效率并不是很高,为了适应现代化生产的要求,该文对压力机的液压系统进行了改良,根据液压缸的位移和系统的压力来调节液压缸的速度,从而大大地提高了压力机的效率。Press is a versatile compact structure machinery. General press has the versatility, speed, efficiency is not very high, in order to meet the requirements of modem production, in this paper, the hydraulic system of the press was modified greatly improve the efficiency of the press. According to the displacement of the oil cylinder and the pressure of the system to adjust the speed of cylinder, thus greatly im- prove the efficiency of the press.
