摘要
本文介绍了CYS-300型全液压地热水井钻机的性能参数、关键机械部件结构及液压系统的设计。钻机选用齿轮泵作为液压系统动力元件,配合液压多路阀实现对动力头双液压马达和给进油缸等执行元件液压油的合流,通过液控二速阀实现动力头双液压马达的串并联工作,输出4种转速和扭矩,在满足钻机性能参数设计要求的同时,简化液压系统的设计,减少液压系统能量损耗,降低维护和使用成本。钻机采用油缸三链条倍速机构实现动力头的给进提升,具有结构简单、性能可靠、抗冲击能力强、提升平稳等优点。现场工程施工应用表明:CYS-300型全液压地热水井钻机性能稳定可靠,工艺和复杂地层适用能力强,操作安全舒适,钻进效率高。
This paper introduces the performance parameters of the CYS-300 full hydraulic geothermal well drilling rig, as well as the design of key mechanical components and the hydraulic system. The gear pump is selected as the power component of the hydraulic system, with the hydraulic multi-way valve to realize the confluence of the hydraulic oil of the top head dual hydraulic motor and the feed cylinder, and the hydraulic control two-speed valve to realize the series-parallel operation of the top head double hydraulic motor to output four speeds and torques. In such a way, the design of the hydraulic system is simplified with reduced energy loss, and low maintenance and operation cost; meanwhile the design requirements of the drilling machine performance parameters are satisfied. The three-chain double-speed mechanism of the oil cylinder is adopted for the drilling rig to realize the feeding and lifting of the top head, providing the advantages of simple structure, reliable performance, strong impact resistance and stable lifting. The field application shows that the CYS-300 full hydraulic geothermal well drilling rig has stable and reliable performance, good adaptability to different drilling processes and complex formation, safe and comfortable operation and high drilling efficiency.
