奥德萨工程建筑学院拟制了一种成批生产的1000吨水压机钢筋混凝土柱塞的典型结构。为了在操作条件下全面地研究其工作,曾制造和研究了500吨П705型立式水压机的柱塞。用钢筋混凝土柱塞代替铸铁(СЧ 24—44)柱塞
Odessa Institute of Engineering and Architecture proposed a batch production of 1000 tons hydraulic machine reinforced concrete plunger typical structure. In order to fully investigate its work under operating conditions, the plunger of a 500-ton П705 vertical hydraulic press was manufactured and studied. Use a reinforced concrete plunger instead of a cast iron (СЧ 24-44) plunger
