Principle of percussive drilling machine
Percussive rotary air percussion drilling is a common drilling technology used in exploration drilling, that is, in the search for minerals. Percussive rotary air drilling is also often used in mine water drilling and borehole drilling,such as the Water Well Drilling Rig.
Percussive rotary air impact (RAB) drilling technique
This drilling technique USES pneumatic pressure to push the steel bit into the ground to form a hole. It is a hammer-like process that easily penetrates rock to find minerals and ores. The bit used is hollow. Debris from the drilling process shoots off the ground and lands next to the machine. Unwanted material will fall to the surface next to the machine by using compressed air forced into the mine. This drilling method is not always the best method to use when exploring a borehole because the material to be sampled may be damaged when drilling from the ground. The percussive rotary blast drilling procedure is usually completed in one day.
Percussive rotary air jet drilling is an ideal method for drilling holes in hard materials such as rock. The percussive rotary blast drilling method can penetrate up to 25 meters. If a mining company wants to sample only a small fraction of the products they are mining, this method is simple and economical to use. When layers of rock at the top of the soil need to be analyzed for minerals, percussive rotatory air can be used to drill boreholes to break up the top rock, allowing the soil below to be detected.

What are the advantages and disadvantages of percussive rotary air drilling?
The greatest advantage of percussive rotary air drilling is that it can be quickly and easily drilled through almost any type of rock.
The biggest disadvantage of percussive rotatory air drilling is that to use the machine effectively, it requires experienced operators, and when the machine can penetrate almost any type of rock, it cannot penetrate the steel-reinforced rock.

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?

  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
