摘 要:用缓释火药作为动力源的电缆桥塞坐封工具,管理手续繁杂、存在安全隐患、管理及使用成本高,现场需要更安全、环保、经济的坐封工具。电动液压电缆桥塞坐封工具用直流电机驱动微型液压泵,由液压泵输出高压油流推动活塞工作,实现电能向机械能的转换,完成桥塞的坐封、丢手。具备在有限空间内提供高坐封拉力、即时恢复工作状态、耐高温高压等多项功能,工具耐温达155℃,工作压力70MPa,输出拉力不小于300kN,达到了国内外同类产品与技术的先进水平,完全可以替代依靠化学能的坐封工具。Cable bridge plug setting tool using sustained-release powder as a power source has a high cost for management and application with hidden faults in safety. Onsite service requires safer, more environmental-friendly and more economical setting tool. Electric hydraulic cable bridge plug uses a DC motor to drive micro hydraulic pump. High-pressure oil flow from hydraulic pump makes the piston work so that electric energy is converted into mechanical energy to set and release the plug. It has a number of functions, such as providing high pulling force for high setting in a limited space, restoring working status in time and resisting high temperature and high pressure. The tool can resist temperature of 155°C and working pressure of 70MPa. The output pull is no less than 300kN. As compared to the products and technology of the same kind both at home and broad, it reaches the advanced level and is able to replace the chemical energy setting tool.
