How do crews clean and maintain the interior of a DTH drilling rig?

　　DTH drilling truck belongs to semi-hydraulic vehicle, that is, except for the impact of compressed air, the rest of the functions are achieved through the hydraulic system, so the quality of hydraulic oil is very important for the normal operation of the hydraulic system. Open the hydraulic oil tank to see 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 drilling rig is high, the hydraulic oil should generally be replaced once every six months. It is forbidden to mix the two hydraulic oils. more related content of DTH drilling trucksPay attention to our Hunan Ruisheng electromechanical equipment, our official website is www.hnzega.com.
　　
　　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. However, due to the wear of hydraulic components in the work, impurities will be inadvertently brought in when adding hydraulic oil, so regular cleaning of the oil tank and oil filter is the key to ensure the cleanliness of the oil, prevent the failure of the hydraulic system and extend the life of the hydraulic components.
　　
　　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, which will affect the lubrication and life of the impactor, 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. When adding lubricating oil, the main intake valve must first be closed, and then the impact valve must be opened to remove the residual gas in the pipe to avoid injury. It is strictly forbidden to work without lubricating oil! 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 climbing ability, propulsion (lifting) force, swing torque and rock drilling efficiency, timely maintenance and maintenance is the premise of the drilling truck to play the best efficiency. The new or overhauled diesel engine must be run in before use to improve the reliability and economic life of the diesel engine. 50 hours of operation at less than 70% rated speed and 50% rated load. After running-in, the oil in the sump should be stopped while hot, the oil pan and oil filter screen should be cleaned with diesel, and the oil and filter should be replaced. After the running-in period, the oil and filter should be replaced every 250 hours of operation. Read the diesel engine instruction manual carefully and do other maintenance matters.
　　
　　Every shift to clean the air filter 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. Therefore, we have set up a secondary air filter (the first stage is a dry paper core air filter, the second stage is an oil-immersed air filter), and added a diesel engine air intake pipe to prevent dust and other dust from entering the body as much as possible to cause wear and pulling cylinders, and extend the service life of the diesel engine. However, the air filter can only temporarily prevent dust from entering the body, and it must be cleaned up after working for a period of time, otherwise the dust accumulation will not only block the air intake channel, but also cause the damage of the air filter, seriously affecting the performance and service life of the diesel engine.
