随着机械工业向高效、精密、大型、自动化方向发展,对液压技术提出了更高要求。电液伺服阀、电液脉冲马达等在液压传动系统中被普遍使用,同时也要求提供相应的液压动力装置(液压柜),对它的要求是:滤油精度高,性能稳定可靠,能24小时连续使用,并有加温、冷却油液的装置及自动控温设备,可加接不同特性回路的集成块。为此:本厂与广州机床研究所共同设计了YG系列液压柜,自73年4月开始生产以来,在全国各地有关数控机床、专用机床、专用设备上实际使用中反映的情况看来,它满足了上述要求。为了向使用电液比例阀、电液伺服阀的液压系统提供高压液压动力装置,以便用户采用,最近又试制成“水冷却高压液压柜”。下面就水冷却高压液压柜作一初步性能介绍:
With the mechanical industry to efficient, sophisticated, large-scale, automated direction, the hydraulic technology put forward higher requirements. Electrohydraulic servo valves, electro-hydraulic pulse motors are widely used in hydraulic transmission systems, but also require the provision of the corresponding hydraulic power unit (hydraulic cabinet), its requirements are: high precision oil filter, stable and reliable performance, to 24 Hour continuous use, and heating, cooling oil device and automatic temperature control equipment, can be connected with different characteristics of the loop manifold. To this end: The factory and Guangzhou Machine Tool Institute co-designed YG series of hydraulic cabinet, since April 73 since the beginning of production in all parts of the country about CNC machine tools, machine tools, special equipment used in the actual situation reflects it seems that it Meet the above requirements. In order to use the electro-hydraulic proportional valve, electro-hydraulic servo valve hydraulic system to provide high-pressure hydraulic power unit for the user to adopt, recently made into a “water-cooled high-pressure hydraulic cabinet.” The following water cooled high pressure hydraulic cabinet for a preliminary performance description:
