In winter, most areas in the north began to implement strike orders, hydraulic down-the-hole drilling rigs were no longer working, and the winter break began. During this period of time when hydraulic down-the-hole drilling rigs are being put on hold, we must not ignore the love of the machine. Introduce to us several precautions for parking hydraulic down-the-hole drilling rigs in winter:
1. In the cold construction season in winter, before the hydraulic down-the-hole drilling rig is put away for storage, you should first conduct a comprehensive physical examination of the hydraulic down-the-hole drilling rig to check for malfunctions and loose parts, as well as clean the dust and dirt on the love body. clean.
2. When storing the rig in winter, remember to retract the exposed cylinder as much as possible to avoid corrosion to the cylinder in humid environments such as snow in winter to prevent the cylinder from rusting. Assuming that it cannot be shortened due to location reasons, a layer of butter can be applied to the surface of the piston rod.
3. The temperature in winter is extremely cold, and when the hydraulic down-the-hole drill needs to be parked for a long time, the coolant in the engine should be emptied. It is also necessary to investigate whether the oil quality of the engine oil is normal, and the old engine oil is likely to corrode engine parts.
4. Special attention should be paid to the location of the drilling rig. It should be parked in a boring indoor environment. Due to the constraints of conditions, most hydraulic down-the-hole drilling rigs are parked outdoors. At this time, you should choose a relatively flat place, and can not be placed in a humid, salt-alkali, dusty environment for a long time.
5. When the drilling rig is parked outdoors for a long time, remember to cover the exposed cylinder with a cloth. For outdoor safety considerations, when storing hydraulic rock drills, carefully check whether there are valuables and flammable and explosive things in the driving room.
6. The hydraulic down-the-hole drilling rig cannot be completely left alone after it is placed. The initiator needs to initiate the operation once a month to avoid problems that do not occur for a long time. When the antifreeze is insufficient, it should be added in time and then launched.
7. Winter maintenance should not be lost. Diesel should be replaced with -10~30 model, light diesel with low freezing point and good ignition performance should be selected; engine oil should be replaced with thickened engine oil suitable for the weather in the area; together, check whether the hydraulic system is available If there is an oil leak, replace it if possible.
