Precautions for the use and maintenance of the new water well drilling rig during the running-in period

　　1. The staff of the new water well drilling rig control should receive the training and guidance from the production manufacturer, have a multi-faceted understanding of the structure and characteristics of the machine equipment, and have the necessary control and maintenance experience to control the machine. The production application maintenance manual provided by the manufacturer is an essential material for the operator to control the machine equipment. Before operating the new water well drilling rig, the application maintenance manual must be read first, and the operation and maintenance should be performed according to the provisions of the manual.

　　2. Pay attention to the workload during the break-in period. The workload during the break-in period should usually not exceed 80% of the rated workload, and appropriate workload should be arranged to avoid long-term continuous work The resulting overheating condition.

　　3. Pay attention to the indicators of new water well drilling rigs. If abnormality is found, it should be stopped in time to eliminate it. If the cause is not found and the fault is not eliminated, the work should be stopped.

　　4. Pay attention to often check the level and quality of lubricating oil, hydraulic oil, coolant, brake fluid and its fuel oil (water), and check the sealing performance of the whole machine. During the inspection, if you find that there is too much oil and water, you should analyze the reason. In addition, the lubrication of each lubrication point should be strengthened. It is best to fill the lubrication points with grease (except for special requirements) in each shift during the running-in period.

　　5. The new water well drilling rig should be filled with lubricating grease to the extractor before work, because dirty water with sand is very easy to enter, and it will wear the bearing to reduce the sensitivity of the drill extractor. To keep the machine clean, adjust and fasten loose parts in a timely manner to prevent aggravation of parts wear due to looseness or loss of parts.

　　6. At the end of the running-in period, the new water well drilling rig should be subjected to mandatory maintenance, inspection and adjustment work should be done, and oil replacement should be noted. In addition, the oil quantity and quality of the fuel tank should be checked before work. It is also necessary to check whether the oil quantity of each gear reducer is sufficient and whether the oil quality is ok.

　　7 Check whether there are cracks, corrosion, desoldering and other damage in the steel structure of the new water well rig. Check whether the main and auxiliary wire ropes are broken and whether their connections are intact and safe.
