一九七六年十月日本国际贸易促进协会在北京展览馆举办了日本环境保护、液压气动工业技术展览会,有六十五家制造厂和三十二家商社参加,展出了日本有关环境保护和液压气动领域的产品和技术。展览会的液压气动部分有十三家制造厂参加,展出了液压泵、液压马达、液压阀、液压辅件、液压油、液压机具、液力元件、气动元件等产品约五十件。由于参加展出的厂家少,展品品种少,所以这次展览会不能完全反映日本液压气动行业的生产规模和技术水平。日本制钢所展出了Thomaflex泵和Lucas HD泵。Thomaflex泵是J.Thoma设计的斜轴式轴向柱塞泵,额定压力为250公斤力/厘米~2,最高压力为320公斤力/厘米~2,最大排量为638毫升/转。这种泵采用铜质缸体、平面配流。Lucas HD泵是转售英国Lucas公司的产品,是一种通轴式轴向柱塞泵。额定压力为280公斤/厘米~2,最高压力为350公斤力/厘米~2,最
In October 1976, the Japan Society for the Promotion of International Trade organized the Japan Environmental Protection, Hydraulic and Pneumatic Industrial Technology Exhibition in Beijing Exhibition Center. Sixty-five manufacturing plants and thirty-two trading companies participated in the exhibition. Protection and hydraulic pneumatic products and technologies. Some 13 manufacturers participated in the hydropneumatic section of the exhibition and exhibited about 50 products including hydraulic pumps, hydraulic motors, hydraulic valves, hydraulic accessories, hydraulic oil, hydraulic equipment, hydraulic components and pneumatic components. As fewer exhibitors to participate in the exhibition, exhibits less variety, so the exhibition can not fully reflect the Japanese hydraulic and pneumatic industry scale of production and technical level. Nippon Steel exhibited the Thomaflex pump and Lucas HD pump. The Thomaflex pump is a diagonal axial piston pump designed by J.Thoma with a rated pressure of 250 kgf / cm2, a maximum pressure of 320 kgf / cm2 and a maximum displacement of 638 ml / rpm. This pump uses a copper cylinder with a flat flow. Lucas HD pump is the sale of the British Lucas company’s products, is a through-axis axial piston pump. Rated pressure of 280 kg / cm ~ 2, the maximum pressure of 350 kg / cm ~ 2, the most
