During the use of the downhole drilling rig, we also need to clean the oil mist and add lubricating oil in time. Downhole drilling rigs use impactors to achieve impact drilling. Good lubrication is necessary to ensure the proper operation of the impactor. Since compressed air often contains moisture, and the pipes are not clean, some moisture and impurities usually remain at the bottom of the injector after a period of use, which will affect the lubrication and service life of the impactor. Therefore, when the injector does not produce oil or there is moisture and impurities in the injector, it should be removed in time. When adding lubricating oil, the main inlet valve must be closed first, and then the shock valve must be opened to remove residual gas from the pipe to avoid injury. Do not operate without lubricating oil!
It is necessary not only to clean and lubricate the injectors, but also to carry out the running-in and oil change of the diesel engine. The diesel engine is the power source of the entire hydraulic system. It directly affects the drilling rig's climbing ability, propulsion (lift) force, rotational torque and drilling efficiency. Timely maintenance and maintenance is the prerequisite for the best efficiency of the drilling rig. New or overhauled diesel engines must be run in before use to improve the reliability and economic life of diesel engines. 50 hours of operation at 70 rpm and 50 loads. After running-in, stop the machine and drain the oil from the oil pan while it is hot. Clean the sump and strainer with diesel fuel and replace the oil and filter. After the break-in period, the oil and filter should be changed every 250 hours.

Clean air filters per shift prevent diesel engines from pulling on the cylinders. DTH drilling truck is popular with users because of its high drilling efficiency, but the higher the efficiency, the more dust will be generated, which will seriously affect the work and life of the diesel engine. Therefore, we have set up a secondary air filter (the first time is a dry paper core air filter, the second is an oil-immersed air filter) on the structure, and a diesel engine intake pipe is added to prevent dust and the like from entering the body, causing wear and cylinder traction as much as possible. Extended the service life of diesel engines. However, the air filter can only temporarily prevent dust and the like from entering the body, and it must be cleaned after working for a period of time, otherwise the dust will accumulate more, which will not only block the air intake channel, but also cause damage to the air filter, seriously affecting the performance and service life of the diesel engine.
The first dry air filter must be cleaned every shift! First, carefully remove the filter element, shake gently to remove most of the dust, and then blow it from the inside out with compressed air, taking care to control the air pressure to prevent the filter element from being blown out. Do not clean paper filters with water, diesel or gasoline! Otherwise, after the hole of the filter element is blocked, the intake resistance will increase, and even the filter element will be damaged. After cleaning, carefully inspect the filter element for damage, and if it does, replace it immediately. When installing the filter element, the connection must be sealed and secure!
The secondary oil-immersed air filter should be cleaned every three days! Under the premise of cleaning the dry air filter once per shift, the secondary oil-immersed air filter can be cleaned every three days. Open the lower part of the filter, take out the metal filter screen and oil pan, carefully clean it with diesel, soak the cleaned filter with engine oil, and drain it for reserve. Fill the engine oil in a clean sump to the scale line, then fill the drained strainer to ensure a reliable seal and lock it. Note: After the filter is cleaned, it must be soaked with oil, and the oil pan must be filled with oil, otherwise the filtration effect will be lost!
The air intake must be kept away from the dust area! The working environment of the underground drilling rig is harsh and the dust is large. Therefore, we added air intake pipes to the primary air filter to keep the air intake of the diesel engine as far away from dust as possible. During operation, the air intake of the intake pipe should be as far away as possible from the dust-dense area, and should not be placed directly on the ground to avoid inhalation of sand! When the dust is very large, the intake pipe can be appropriately lengthened.
