What do we need to know about the precautions and daily maintenance of the work of the drilling rig? Now the small editor of Hunan Ruisheng Electromechanical equipment takes you to understand that the following is the precautions for the work of the drilling rig
What are the precautions and daily maintenance of DTH drilling rig work, now Hunan Ruisheng Mechanical and Electrical Equipment Xiaobian takes you to understand, the following are the precautions for DTH drilling rig work
< /> 1. The DTH drilling rig should pay attention to its sound, vibration and the operation of various parts during the normal drilling process, when abnormal sound and vibration, current rating are found. Check and deal with it in time to ensure that the DTH drilling rig is working in normal condition. < /> < /> 2. When it is found that the drilling speed of the DTH drilling rig has changed significantly, and the powder discharge effect is not good. It is necessary to drill in time to check the condition of the drill bit and gun hole. If the stone is found, it should be stopped immediately, the drilling tool should be raised, and the yellow mud or fine rock with water added to the hole should be poured into the hole as a binder, and then continue to drill the rock, and the binder should stick to the broken hole wall of the partial gang under the action of pressure and drill pipe, so that the hole wall of the crushing belt is complete and the normal drilling is maintained. < /> < /> 3. During the drilling process of the DTH drilling rig stove, special attention should be paid to and prevent the occurrence of clamping drilling phenomenon, because the clamp driller does not affect the hollowing progress, and if it is not handled properly, it will have a certain impact on the relevant parts of the DTH drilling rig, and even, damage the relevant components.
4. During the DTH drilling process, attention should also be paid to the change of air pressure. If the air pressure suddenly decreases, first lift the drilling tool a little, the control valve closed after inspection, if the air pressure still does not rise, it means that it is not a problem with the drilling tool and eyelets, but a problem with the air supply system, if the control valve is closed, the air pressure rises, at this time, the drilling tool should be put out of the hole, check whether the drill pipe, impactor has cracks or air leakage, if the air pressure suddenly increases in the rock drill, it is the impact valve cabinet blockage, should be removed and cleaned. < /> < /> 5. When drilling the seepage hole, due to power failure or failure can not be put out of the drilling tool to cause magma pouring impactor, at this time, you can add some water to the drilling tool, and then use pressure gas to rinse, until the DTH drilling rig drilling tool can be raised and then stop gas, disassemble the impactor for cleaning. < /> < /> Daily maintenance and maintenance of DTH drilling rigs:
< /> 1. Regularly check the hydraulic oil, the DTH drilling truck belongs to the semi-hydraulic vehicle, that is, in addition to the impact of compressed air, the rest of the functions are achieved by the hydraulic system, so the quality of the hydraulic oil is crucial to whether the hydraulic system can work normally. < /> < /> 2. Clean the oil tank and oil filter regularly, the impurities in the hydraulic oil will not only cause the failure of the hydraulic valve, but also aggravate the wear of hydraulic components such as oil pump and hydraulic motor, so we set up an oil suction filter and an oil return oil filter on the structure to ensure the cleanliness of the circulating oil in the system as much as possible. The key to longevity. < /> < /> 3. Clean the lubricator and add lubricating oil in time, the DTH drilling truck is through the impactor to achieve impact drilling, good lubrication is a necessary condition to ensure the normal operation of the impactor. Because the compressed air often carries moisture and the pipeline is not clean, after a period of use, the bottom of the lubricator often retains certain moisture and impurities, so when it is found that the lubricator does not produce oil or there is moisture and impurities in the lubricator should be eliminated in time. < /> < /> 4. Do a good job of diesel engine running-in and oil replacement, diesel engine is the source power of the entire hydraulic system, it directly affects the drilling rig's climbing ability, propulsion (lifting) force, swing torque and rock drilling efficiency, timely maintenance and maintenance is the premise of drilling truck to play the best efficiency. < /> < /> 5. Clean the air filter every shift to prevent the diesel engine from pulling the cylinder, the DTH drilling truck is loved by users because of its high rock drilling efficiency, but the higher the efficiency, the more dust is generated, which has a serious impact on the work and life of the diesel engine. < /> < /> More < a href="http://www.hnzega.com/news.html" > DTH drilling vehicles need to know about consultation, come to our Hunan Ruisheng Electromechanical Equipment Co., Ltd., our official website is www.hnzega.com.
