CM358A Crawler Mounted Hydraulic DTH Drilling Rig

CM358A Crawler Mounted Hydraulic DTH Drilling Rig
Crawler Mounted Hydraulic DTH Drilling Rig
Crawler Mounted DTH Drill Rig, Hydraulic Crawler Drills
In contrast to the pneumatic drilling rig, energy consumption (diesel or electricity) saves about 40% to 50%.
Borehole Diameter
90-165mm
Site Condition
CM358A crawler mounted hydraulic DTH drilling rig is mainly applicable to the blast hole drilling process of open pit mining, quarrying, hydropower project and road constructions.
Product Features
CM358A crawler mounted hydraulic DTH drilling rig adopts diesel engine (or electric motor)  and hydraulic oil pump assembly to provide power, allowing rigs to finish moving, rotating, feeding and lifting, as well as angle positioning. 
During operation only the percussive DTH rigs consumes compressed air and in contrast to the conventional pneumatic rigs, CM358A saves about 40%~50% of total energy.

What Are the Types of Drilling Rigs?

图片
With the continuous development of   drilling rig machine  production , the use conditions of drilling rigs are becoming more and more diverse, and various types of drilling rigs have appeared accordingly. Factors affecting the type and composition of drilling rigs include drilling methods, drilling depth, borehole size and drilling tool size, drilling area conditions (such as electricity or fuel, transportation, meteorological conditions), etc. The  t ruck mounted drill rig  is the main machine  that completes the drilling construction. It drives the drilling tool and the drill bit to the deep part of the formation and completes the lifting and lowering of the drilling tool and casing, and the extraction of the core through the elevator (winch) on the drilling machine. , Auxiliary work such as replacement of drill bit. The main function of the pump is to deliver flushing fluid into the hole to clean the bottom of the hole, cool the drill bit and lubricate the drilling tool. Dri

What Happens When Hydraulic Drilling Rigs Use Emulsified Hydraulic Fluid?

图片
  The emulsification of hydraulic fluid is the deterioration of hydraulic fluid. The use of emulsified hydraulic oil will have a very serious impact on the hydraulic system of hydraulic   drilling rigs , which is called the "white blood disease" of hydraulic drilling rigs.   Performance of hydraulic oil emulsification If you find that the hydraulic components of the hydraulic column drilling rig are weak, there are obvious bubbles in the oil tank and the oil temperature is too hot, it is recommended to open the oil tank cover to check whether the oil is white, if it is white and emulsified, it is recommended to clean the pipeline and replace the pure hydraulic oil immediately. Can no longer use emulsified hydraulic oil, "white blood disease" will really ruin the hydraulic drilling rig!   The danger of emulsified hydraulic oil to  hydraulic drilling rigs Hydraulic fluid emulsification is the deterioration of the hydraulic fluid. The use of emulsified hydraulic oil wi
