Everyone has heard of water well drilling tools. Due to the characteristics of good maneuverability, compact structure, and strong integrity, the complexity of its production and operation can be seen in general. However, during the daily use of water well drilling tools, some failures will inevitably occur. Let's take a look at the four common failures of water well drilling tools:

　　1. The main reason for the slip of the water well drilling tools clutch is excessive friction or wear of the friction plate or the aging or breakage of the compression spring. The friction plate of the drilling rig should be repaired.

　　2. The coupling of the water well drilling tools is hot and the elastic ring is excessively worn; the reason is that the coaxial of the drilling rig power machine and the clutch is poor, and the assembly coaxially needs to be improved.

　　3. The main brake of the water well rig winch slips, the main reason is that there is oil on the inner surface of the brake belt, and the inner surface of the brake needs to be removed. If there is no oil in the water well rig brake, the gap between the brake belt and the brake wheel needs to be checked. Properly adjusted;

　　4. After the oil pump of the water well rig is started, it will not be filled with oil or the amount of oil is insufficient. First, check whether the amount of oil in the oil tank is insufficient or no oil. If the common faults of the water well rig that is filled to the oil level are still not eliminated, check whether the filter is blocked. Also, Also, check whether the vent hole of the fuel tank is blocked, or the suction pipe joint is loose and the air intake is caused.

　　Common faults of water well drilling tools 5. The oil pumps of water well drilling tools are heated and worn. The oil pumps must be repaired and replaced. The viscosity of the oil is too high or too low. The oil should be used in strict accordance with the instructions. At the same time, the transmission device of the oil rig oil pump should be checked to improve the assembly accuracy.
