为满足各种液压机械发展的需要,齿轮泵在不断地向着高压力、高效率、高寿命和大排量方向发展。目前,我国生产的齿轮泵多属中高压齿轮泵。为填补我国齿轮泵的空白,天津工程机械研究所和济南液压泵厂合作设计出一种新的特殊结构的外啮合齿轮泵,经过三年多的时间终于研制成功,在一九八四年通过了国家鉴定,并已批量生产与主机配套。
In order to meet the needs of the development of various hydraulic machinery, gear pumps continue to be high pressure, high efficiency, high life expectancy and large displacement direction. At present, most of our gear pumps are medium and high pressure gear pumps. To fill the gaps in gear pumps in China, Tianjin Engineering Machinery Institute and Jinan Hydraulic Pump Factory to design a new special structure of the external gear pump, after more than three years of successful development finally passed in 1984 The national appraisal, and has been mass production and supporting the host.
