长江液压件厂研制开发的一种有高速、高压、小排量性能的新型齿轮泵——CBKO型齿轮泵,于1994年12月20日在该厂通过省级技术鉴定。 该新型液压泵系移植国际同类产品先进技术,由长液厂独立设计、研制。它具有设计先进、结构合理、工艺性好等优点,技术参数达到国际90年代初期同类产品先进 A new type of gear pump with high speed, high pressure and small displacement, CBKO gear pump developed and researched by Changjiang Hydraulic Parts Factory passed the provincial technical appraisal on December 20, 1994. The new type of hydraulic pump is transplanted with the advanced technology of the same kind of international products and independently designed and developed by the long-term liquid plant. It has the advantages of advanced design, reasonable structure and good processability. The technical parameters have reached the advanced level of similar products in the early 1990s.
