CBQ—F500新型齿轮泵,额定使用压力200～250kgf/cm~2,转速最高达3000转/分。为此制造一种机械性能高、耐气蚀、耐压、耐渗漏性好的铝合金泵体,是达到上述设计性能指标的关键。我厂采用液态模锻这一先进工艺代替金属模铸造试制了泵体。试验结果表明,液态模锻泵体性能和组织远比铸造的好,各项技术指标都达到和超过了设计指标,容积效率高达96％。通过了机械部的鉴定,已批量投入生产。
CBQ-F500 new gear pump, rated pressure 200 ~ 250kgf / cm ~ 2, speed up to 3000 r / min. To create a high mechanical performance, corrosion resistance, pressure resistance, good resistance to leakage of aluminum alloy pump body, is to achieve the above design performance key. I plant the use of liquid die forging the advanced technology instead of metal mold trial of the pump body. The test results show that the performance and organization of the liquid forging pump are much better than the castings. The technical indicators have reached and exceeded the design targets, and the volumetric efficiency is as high as 96%. Passed the identification of the Ministry of Machinery, has been put into mass production.
