ST 50 Borehole Drilling Rig Machine Daily Maintenance
⑴ The daily maintenance shall be carried out by the actual operation technicians, and the record form shall be filled in carefully;
⑵ The drilling rig shall be cleaned before each shift handover. The linear guide surfaces of the upper and lower carriages, vertical shafts and pistons are usually stained with sludge when pulling out of the hole. These contact surfaces should be wiped clean and oil should be added;
(3) Before each shift, check whether the oil level of the hydraulic box is suitable for the oil level of the gearbox. If the oil level is too low, fill the grease immediately;
(4) The actual operation technicians of each shift shall add a layer of lubricating grease to the oil cup on the linear guide surface of the upper frame. Fill the oil cup of the clutch release shaft pump oil cup chuck beam with lubricating grease once a month;
(5) The actual operation technicians must inspect the oil filter screen every week, and clean it immediately if there is any blockage.
Where are the underground water sources?
Many novices will ask where the groundwater is when they use the drilling rig?
To answer this question with common sense, there is a layer of stone wrapped around the earth's surface, which is bedrock. There are cracks in bedrock, and water is in the cracks.
The area lower than the mountain is covered by clay, sand and pebbles. This is a loose layer. The clay particle size is small, and there is no space between particles. There is no water. The particle size of sand and pebbles is large, and the space between particles is large, so there is water.
