The complexity of the production and operation of a water well drilling rig is evident due to its good mobility, compactness and integrity. But inevitably some faults will occur during the daily use of the water well drilling rig. Here is a detailed introduction to the seven common faults and solutions of water well drilling rigs!
Common faults of water well drilling rigs I. Slipping of the clutch of the drilling rig, mainly due to excessive wear or rupture of the friction plate or aging or fracture of the compression spring, the friction plate of the drilling rig should be overhauled.
Common faults of water well drilling rigs II. The drilling rig coupling is hot and the elastic ring is excessively worn; the reason is that the coaxiality of the drilling rig power machine and clutch assembly is poor, and the coaxiality of the assembly needs to be improved.
Common faults of water well drilling rigs III. slippage of the holding brake of the drilling rig winch, the main reason is that there is oil on the inner surface of the holding brake belt, and the inner surface of the holding brake needs to be cleared; if there is no oil in the holding brake of the drilling rig, the brake belt and brake wheel clearance should be checked, and if they are too loose, they should be properly tightened.
Common failures of water well drilling rigs Ⅳ, drilling rig oil pump after starting not on the oil or insufficient oil, the first row to check whether the amount of oil in the oil tank is insufficient or no oil, refueling to the oil level line common failures of water well drilling rigs such as still not ruled out, to check whether the filter is blocked, in addition, also look at the oil tank vent hole is blocked, or suction pipe joints loose air intake and other reasons.
Common faults of water well drilling rigs V. The oil pump of the drilling rig is hot and worn, the oil pump must be repaired and replaced, the viscosity of the oil is too high or too low, the oil should be used strictly according to the manual; meanwhile, check the transmission device of the oil pump of the drilling rig to improve the assembly accuracy.
Common failures of water well drilling rigs VI. the oil temperature of the hydraulic system is too high, the oil in the tank is too little or the oil pump is damaged, the oil pump should be refuelled or repaired; the working pump should be chosen reasonably and the working pressure should be recommended according to the manual.
Common failures of water well drilling rigs VII. insufficient pressure in the hydraulic system of the drilling rig, regulator fatigue to adjust the limit nut or replace the spring; if the regulator seat cone is damaged or jammed, remove the regulator sleeve briefly for overhaul.
