介绍了ＣＣＤＢ型系列磁传动水平注水泵的结构特点、工作原理、关键技术、室内试验及现场应用情况。采用组合推拉磁路设计的小体积、耐高压、高效率磁力驱动器与高扬程多级离心泵匹配， 从根本上解决了目前油田增压注水泵高压条件下机械密封存在的介质泄漏、检修频繁、可靠性低等问题， 具有结构紧凑、运行平稳、噪音低、使用寿命长、方便管理等优点。现场应用表明， 该系列注水泵用于油田增压注水及作为水力泵抽油工艺配套动力设备， 可获得显著的经济效益和社会效益。 The structural characteristics, working principle, key technologies, laboratory tests and field application of CCDB series magnetic horizontal injection pumps are introduced. The combination of small volume, high pressure resistant and high efficiency magnetic drive designed by combination of push-pull magnetic circuit and high-lift multi-stage centrifugal pump fundamentally solves the problem of medium leakage in the mechanical seal under the condition of high pressure in the oilfield booster pump, Low reliability, with a compact, smooth operation, low noise, long life, easy management and so on. The field application shows that this series of water injection pumps are used for pressurized water injection in oilfields and as a power equipment for hydraulic pumping technology, which can achieve significant economic and social benefits.
