文章通过分析与实测 ,指出油液的污染和过热是造成液压锚杆钻机故障率高的主要原因。按照液压锚杆钻机的使用要求 ,研制了能同时降低油温和控制污染 ,流阻低的冷却净化器。在锚杆钻机液压系统中使用证实 ,冷却净化器能显著的提高锚杆钻机的可靠性并延长其使用寿命。 Through the analysis and measurement, the article points out that the pollution and overheating of the oil are the main causes of the high failure rate of the hydraulic bolting. In accordance with the requirements of the use of hydraulic anchor rig, developed a cooling purifier that can reduce oil temperature and control pollution, low flow resistance. The use of the anchor drill hydraulic system confirmed that the cooling purifier can significantly improve the reliability of the anchor rig and extend its service life.
