atlas copco凿岩台车液压系统典型故障诊断方法（阿特拉斯柯凿岩台车液压系统典型故障诊断方法） 5-21 Purpose and significance of the present operation method In our corporation adopts hydraulic system equipment throughout the production line, the hydraulic system with its superior transmission characteristics for various production activities group plays an irreplaceable positive role, but for now the hydraulic system fault diagnosis is difficult and excluded in the production practice has been a problem for maintenance maintenance personnel work efficiency, at the same time it is also restricting the hydraulic transmission technology is more widely applied and more efficient for the drawbacks of our production and management contributions, the operation is in the hydraulic transmission system is made on the basis of the in-depth study, make full use of portable infrared thermometer, and the appearance of typical faults of hydraulic principle the fast and accurate diagnosis and exclusion in-depth research and exposition. Heres to Atlas Copco drilling rig hydraulic system is more complicated for rapid and accurate diagnosis of typical faults for example. (a) and two mining companies use Atlas Copco Jumbo Size Two mining area currently has Atlas Copco drilling rig 18, mining company in 2, with the recent scale of mining in Jinchuan mining area continues to expand, two mining area, three mining area and Longshou Mine will be gradually put into 10 units. At the end of this year, Jinchuan group company will have 30 sets of Atlas Copco drilling rig working underground mining. (two) the basic composition of the hydraulic system of the Atlas Copco drilling rig Atlas Copco Jumbo group company in Jinchuan using H126, H128, Rocket, Boomer/Boomer282 and modified BH252 several models, the main work of hydraulic system DCS12. In the hydraulic system, hydraulic components and precision have adopted the German Rexroth Corporation and the American Parker company, basically by the variable axial piston pump, double gear pump, t
