How to maintain horizontal directional drilling rig

Routine inspection before start-up of horizontal directional drilling rig. Check whether each control valve returns to its original position. If the equipment is connected to the drilling tool, it is necessary to remind the personnel near the drilling tool to avoid it. Clean and lubricate the drill rails. The operation of the equipment must be carried out by designated personnel and strictly abide by the equipment operating procedures. Winter construction should consider the antifreeze problem of water and mud system. During the operation of the drilling rig, the jacking, rotation, mud pressure gauges of the drilling rig, charging, water temperature, and oil temperature gauges of the diesel engine should be checked frequently. Before using the transfer case, check whether the rotating parts are flexible and smooth, and whether the connecting parts are damaged. Otherwise, spare parts should be used. After the instrument is used up, the surface should be cleaned, and the battery should be removed from the battery if it is not used for a long time. Good running record.

Horizontal directional drilling rig construction checks whether the oil pipes and water pipes are fully connected and firmly connected. It is strictly forbidden to disassemble and install the oil pipe during the start-up period or start the machine without the oil pipe being properly installed and the valve position not returned. Start the diesel engine to warm up for 10-30 minutes (determined according to the ambient temperature). All threads, pin connections, and rotating parts should be cleaned and coated with thread thread oil or butter. After the diesel engine stops, the power to the solenoid valve should be disconnected in time. Check whether the water channel of the drilling tool is unimpeded. Check the threaded part of the drilling tool and the drill body for serious wear, roughness, end face defect, and serious deformation in time. If there is any, it should be marked in time and repaired. If it is serious, it should be done. Except for scrapping, it is strictly forbidden to use it again. After the splitter is used, it should be disassembled for maintenance. When the battery is used up, it should be taken out from the drill bucket in time, and the battery should be pulled out to clean the surface.
