I. Installation of  DTH drill rig : 1. The size of the rock drilling space preparation space can be determined according to the type and method of drilling. 2. Bring gas water near the point of use (if water and dust removal is needed), pipes, lighting circuits, etc. 3. Hole position According to the design requirements, we guarantee the stable positioning of the rig. Second, check before operation: 1. When starting work, please carefully check whether the gas and water (if water and dust removal) pipes are tightly connected, especially if the Fengshui pipe joint and the Fengshui pipe are tightly connected to prevent tripping. You should check for injuries and not allow all joints to leak . 2. Make sure the oil mist is full of organic oil (not too much). 3. Check whether the screws, nuts, joints, etc. of each part of the small-scale down-hole drilling rig for photovoltaic piles are tightened, and that the positions are firm and firm. 3. Drilling work procedures and...

Development: The domestic  DTH drill rig  was first produced in the Xuanhua area of Hebei in the 1950s. Through the continuous investment of the country and its own development, the performance and technical content of the rig have been greatly improved. Later the world's top 500 companies in the United States, Sweden, and other countries came to Xuanhua to invest in building factories or joint ventures. Its products and production technologies are used as scientific textbooks for scientific research and teaching. Therefore, the synonym for down-the-hole drilling rigs in China is also called "Xuanhua drilling rigs." Since the 1990s, Hebei Xuanhua has formed an equipment production base. Some enterprises focus on the development and production of the latest type of high-performance, low-consumption, open-air various types of drilling machines, and at the same time, they can be used as accessories. The product is widely used in large, medium and small mines, hydropower...

The essence of the downhole rock drilling is to infiltrate the impactor into the hole during the rock drilling process to reduce the energy loss caused by the impact energy transmitted by the drill rod, thereby reducing the influence of the hole depth on the rock drilling efficiency. First, check the hydraulic oil regularly DTH Drilling Rigs  are semi-hydraulic vehicles, that is, except for the impact of compressed air, the rest of the functions are realized by the hydraulic system, so the quality of the hydraulic oil is essential for the hydraulic system to work properly. 1. Open the hydraulic oil tank and watch if the color of the hydraulic oil is clear and transparent. If it has been emulsified or deteriorated, it must be replaced immediately. If the frequency of use of the drill car is high, the hydraulic oil should be replaced once every six months. It is forbidden to mix two kinds of hydraulic oil! 2. The hydraulic oil used in the  DTH Drill Rig  is anti-we...

DTH Drill Rig  should pay attention to the maintenance and lubrication of the machine, which can reduce its failure. Although it pays attention to reduce the fault after maintenance, there will still be certain faults. The downhole drilling rig sometimes has a stuck drill fault, which causes this fault. What are the general reasons? 1, the bit is broken 2. The new replacement bit is larger than the original diameter; 3. The machine displacement or the drilling tool is deflected in the hole during rock drilling; 4. When the rock is rocking, the wall or the hole drops the rock or encounters large cracks and caves; 5. Dust is difficult to discharge in the area where there is mud stone; 6. Inadequate operation, when the drilling is stopped for a long time, there is no pure rock powder, and the drilling tool is not lifted, so that the impactor is buried by the rock powder; Treatment method: Regarding the strength of the current bit, the broken wing has been basically elim...
