液压与气动系统的可靠性与稳定性一直是液压行业十分重视的问题。目前,在液压与气动行业,已越来越广泛地采用电子计算机。在国外,将微型计算机或微处理器加上流量、压力或位置传感器与各种阀缸做成一体的产品已经问世。预计在今后几年中“微机热”将会得到进一进迅速发展。随之而来的系统可靠性,不仅仅涉及到液压与气动元件、油液污染等方 Hydraulic and pneumatic system reliability and stability has always been the hydraulic industry has attached great importance to the issue. At present, in the hydraulic and pneumatic industries, electronic computers have become more and more widely used. Abroad, microcomputers or microprocessors with flow, pressure or position sensors and a variety of valve cylinder products have been made. Expected in the next few years, “Microcomputer fever” will be further developed rapidly. The ensuing system reliability, not only related to hydraulic and pneumatic components, oil pollution and other parties
