Maintenance during Horizontal Directional Drilling Machine construction

Routine inspection of Horizontal Directional Drilling Machine before start-up. Check whether each control valve returns to its original position. If the equipment is connected to the drilling tool, the personnel near the drilling tool must be reminded to avoid it. Clean and lubricate the drill rails. equipment operation
Line, 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. Check whether the rotating parts are flexible and lubricated, and whether the connecting parts are damaged, otherwise use spare parts. After the instrument is used up, the surface should be cleaned, and the battery should be ejected if it is not used for a long time. After the walkie-talkie is used up, the surface should be cleaned, the battery should be checked, and it should be charged in time to run each time it is turned on, and the operation record should be made.
Horizontal Directional Drilling Machine Construction Check whether the oil pipes and water pipes are fully connected and firmly connected. It is strictly forbidden to disassemble or install the oil pipe during the start-up, or start the machine before the oil pipe is connected properly and the valve position is not returned. Start the diesel engine to warm up for 10-30 minutes (determined according to the ambient temperature). All threads and pins should be cleaned and coated with 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, and end face defects in time. If necessary, mark and repair it. If it is serious, it should be discarded and discarded, and it is strictly forbidden to use it again. After the transfer box is used under heavy load, it should be disassembled for inspection. When the signal rod is used up, it should be removed from the drill in time, and the battery should be withdrawn to clean the surface. Instruments and intercoms should be waterproofed, and should be kept by special personnel after use. During the construction period, the maintenance work of the normal period of the equipment should be carefully done.
