我省湖北农机液压件厂参加了中高压齿轮泵系列新产品的设计工作,并承担了四模数组的试制和试验任务。该厂在洛阳拖拉机研究所和有关单位的大力协助下,试制出了一、型号及基本参数:齿轮泵四模数组,经过两年的反复改进、试验,各项性能指标均达到设计要求。湖北省机械工业局于六月上旬邀请有关农机液压件厂、科研 Hubei Province, Hubei Agricultural Machinery Hydraulic Parts Factory participated in the design of high pressure gear pump series of new products, and assumed the trial of the four-module array and test tasks. The plant in Luoyang Tractor Institute and the relevant departments with the help of a trial trial out of a model and basic parameters: gear pump four modules, after two years of repeated improvement, testing, the performance indicators have reached the design requirements. Hubei Machinery Industry Bureau in early June invited agricultural machinery hydraulic parts plant, scientific research
