Pre-operation inspection of
water well drilling rig: 1. Check whether organic oil has been installed in the oil atomizer (it should not be too full) when starting work. 2. When you start work, you should carefully check whether the gas and water pipes (when water and dust are required) are firmly connected, especially the connection between the fengshui pipe joint and the fengshui pipe must be firm to prevent the tripping from hurting people, and the connection is not allowed There is air leakage. 3. Check
water well drilling rig whether the screws, nuts, joints and other parts of each part are tightened, and whether the various positioning is firm and reliable.
Some common fault treatment of
water well drilling rig
1. The impactor does not sound of
water well drilling rig:
1. The following four situations are common: (1) the valve piece is broken; (2) the tail of the drill head is broken and the ballast enters the cylinder block to block the hammer body; (3) the exhaust hole is blocked by rock dust; (4) When chiseling down, the water accumulated in the hole has more exhaust resistance, and the impactor is not easy to start.
2. Treatment method: When it is found that the impactor is not sounding, first check according to the above four reasons; the inspection method is to raise the impactor for a period, reduce the exhaust resistance, spray water out of a part, and then slowly push it to the bottom of the hole, If this method does not work, it is likely to belong to the first three reasons, the impactor needs to be removed for cleaning or replacement.
Second, broken drill pipe of
water well drilling rig:
1. In most cases, the drill pipe breaks due to friction between the drill pipe and the hole wall, which makes the wall thickness of the drill pipe thinner and the strength weakened too much, causing the drill pipe to break.
2. Preventive treatment: the water well drilling rig should pay attention to the inspection when adding the drill rod, and stop using the drill rod with excessive friction.
