摘要
动力头是旋挖钻机的关键部件,当外界环境温度较高,动力头在重载下长时间工作时,动力头减速机和动力箱内齿轮油温度过高。为此设计了一套动力头齿轮油冷却过滤液压系统,使齿轮油温度和清洁度控制在合理范围内,可有效延长动力头使用寿命。
Rotary drive is a key component of rotary drilling rig. When the rotary drive has been overloaded with work for long hours under high external temperature, the gear oil temperature of its reducer and power box will be too high. So a set of rotary drive gear oil cooling and filtration hydraulic system is designed to control the gear oil temperature and cleanliness within a reasonable range. The rotary drive service life is extended.
