市场调查表明,与量大面广的东方红-75和铁牛-55拖拉机、推土机配套的 CB-46和 CB-32齿轮油泵的使用寿命短(500～800小时),且随着主机的改进,技术参数指标不能满足配套要求(系统工作压力要提高到16兆帕)。CBN-E400和 CBN-E500齿轮泵虽在压力参数上能满足改进后主机的要求,但联结尺寸与东方红-75推土机配套的CB-46泵大不相同,必须作较大的改动。为满足配套要求,洛阳拖拉机研究所和江苏淮阴机械厂联合研制了 CBN-E400A 齿轮
Market research shows that with the large amount of Dongfanghong-75 and Tractor-55 tractors, bulldozers CB-46 and CB-32 gear pump service life is short (500 to 800 hours), and as the host of improvements , Technical parameters can not meet the matching requirements (system pressure to be increased to 16 MPa). Although the CBN-E400 and CBN-E500 gear pumps can meet the requirements of improved mainframes on the pressure parameters, the connection size is very different from that of CB-46 pumps supplied by Dongfanghong-75 Bulldozer. Major changes must be made. To meet the matching requirements, Luoyang Tractor Institute and Jiangsu Huaiyin Machinery Factory jointly developed the CBN-E400A gear
