电液脉冲马达是一种由数字脉冲控制的液压元件,数字机无需经过数模转换就能控制它的转速或转角,开环或闭环。另一种数字元件是数字阀,它刚刚出现。其优点是尺寸小,精度高,缺点是价格偏高。对液压参数的数字控制,人们是感兴趣的,因为电脑必将深入各行各业,液压也不例外。作者曾经碰到使用比例阀经数模转换与微机相连的实例。可见,数控是人们的追求目标。本文介绍用阀组形式实现压力及流量的数字逻辑控制。这种控制方式的缺点是体积大,
Electro-hydraulic pulse motor is a digital pulse-controlled hydraulic components, digital machine without going through digital-to-analog conversion can control its speed or angle, open-loop or closed-loop. Another digital element is the digital valve, which has just appeared. Its advantage is the small size, high precision, the disadvantage is the high price. People are interested in the digital control of hydraulic parameters because the computer is bound to go into all walks of life with no exception. The author encountered an example of using a proportional valve connected to a microcomputer via digital to analog conversion. Can be seen, NC is the pursuit of people’s goals. This article describes the digital logic control of pressure and flow using a valve block. The disadvantage of this control method is bulky,
