气缸是气动技术中的重要执行元件。长期来上海在气缸元件生产中由于没有专业的气缸生产厂而感到不便。现在由上海群益机械厂生产的IQG系列单杆双作用气缸已填补了这一空白,并在86年底通过了鉴定。 IQG系列的气缸体采用了LY硬铝合金和硬质阳极氧化工艺,使气缸筒表面硬度较高,且轻、防锈、防腐、外观美;支承环采用聚四氟乙烯,使密封可靠、 Cylinders are important actuators in pneumatic technology. For a long time in Shanghai in the production of cylinder components because there is no professional cylinder manufacturing plant and feel inconvenient. Now IQG series single-rod double-acting cylinder produced by Shanghai Qunyi Machinery Factory has filled this gap and passed the appraisal in the end of 86. IQG series cylinder body adopts LY hard aluminum alloy and hard anodizing process, which makes cylinder barrel surface hardness higher, light, rust-proof and anticorrosive, and has beautiful appearance. The supporting ring adopts polytetrafluoroethylene to make the seal reliable,
