GB3452·3—88《液压气动O 形橡胶密封圈沟槽尺寸和设计准则》国家标准,是由中国农机院等有关单位经过几年的努力编制而成的。该标准适用机械行业各部门各种主机液压、气动系统中,应用广泛。目前,中国农机院液压公司根据GB3452·3—88标准,在IBM—PC 机上开发和研制成功了“O 形橡胶密封圈计算机选用系统”软件。此软件为设计人员选用O 形圈及计算沟 GB3452 · 3-88 “Hydraulic Pneumatic O-ring groove size and design guidelines” national standards, by the China Agricultural Machinery Institute and other relevant units after several years of hard work compiled from. The standard applies to all sectors of the mechanical sector hydraulic, pneumatic systems, widely used. At present, the Hydraulic Company of China Agricultural Machinery Corporation has developed and developed the “O-ring Rubber Sealing Computer Selection System” software on IBM-PC according to GB3452 · 3-88 standard. This software chooses O-rings and ditches for designers
