在上海新华筒管厂使用的塑料注射成型机上,预塑机构过去采用电机齿轮箱传动螺杆来实现。这种传动机构噪音大、耗电多,特别是预塑齿轮、摩擦片等极易损坏。停机检修既费工时又造成经济损失。为此,上海新华简管厂采用上海飞机制造厂生产的BM—Z(S)端面配流液压马达代替预塑机构的电气机传动。改装后使用半年多证 At the plastic injection molding machine used in Shanghai Xinhua Bobbin, the pre-molding mechanism used motor gearbox drive screws in the past. This kind of transmission mechanism has a lot of noise and consumes much power, especially the pre-molded gears, friction plates, etc. are easily damaged. Downtime is both time-consuming and economical. For this reason, the Shanghai Xinhua Jane Pipe Factory uses the BM-Z(S) end-face-distribution hydraulic motor produced by the Shanghai Aircraft Manufacturing Plant to replace the electrical machine drive of the pre-molding mechanism. Use more than half a year after modification
