JC—70DB单轴绞车的设计研究

Design of Model JC-70DB single shaft drawworks.

国内生产的变频绞车受功率偏小 ,速度范围较窄以及变频电动机性能还不够完善等方面的限制 ,导致其应用范围有限 ,发展速度较慢。为此 ,研制了JC— 70DB新型交流变频齿轮传动单轴绞车。该绞车由 2台交流变频电动机驱动 ,功率大 ,变频调速范围宽 ,可在 0～ 14 0Hz范围内平滑调速 ,最高转速达 2 80 0r/min ;绞车集机、电、气、液为一体 ,采用先进的交流变频(VFD)控制系统 ,触摸屏显示 ,全数字控制等新技术 ,自动化及智能化水平高。JC— 70DB单轴绞车从设计思路和设计方法上彻底改变了传统的思维模式 。

Model JC-70DB AC variable-frequency gear-driven single shaft drawworks is developed to meet the need of the modern drilling technology. The new drawworks is driven by two AC variable-frequency electric motor, and its speed can beregulated in a range of 0-140 Hz with a max of 2 800 r/min. The drawworks adopts advanced AC variable-frequency device (VFD) control system and touch screen display and total numerical control, therefore it is highly automatic and intelligent, and has high adaptability.
