Top Hammer Drilling Tools is a kind of engineering drilling machine, we should make full preparations for inspection before use, so as to avoid the machine malfunction during the working process. The specific content includes:
　　 1. Check all components of the water well drilling rig, whether the installation is stable and reliable, whether the steel ropes and connections are intact, and remove the dust and mud from the drilling rig.
　　2. Check whether the handles are flexible and easy to use, the positioning is tight, and the tightness of each V-belt is appropriate (especially for the main and auxiliary winch brakes and two friction clutch handles), and adjustments are needed if necessary.
　　 3. Check the power machine and mud pump. The steering should be correct.
　　 4. Lubricate the parts of the drilling rig in accordance with the lubrication specifications and diagrams.
　　 5. Fill the gearbox, turntable, and the turbine box of the main winch with oil as required.
　　6. ​​Disengage the diesel engine clutch, the mud pump clutch, turn the V-belt feed handwheel when the empty car is empty, observe the gearbox, the universal shaft of the main and auxiliary hoist, and whether the turntable has any collision or seizure. If so, adjust it.
　　7. Stir the mud. In order to ensure the drilling quality and drilling efficiency, a certain quality and a certain amount of mud must be prepared before drilling. Generally, 600mm wellhead pipe protection is used to open the Quaternary stratum. The mud must be no less than 4m3 and the viscosity is 10-20Pa. .s between.
　　 After checking the components of DTH Drill Pipe, a no-load test run should be carried out. Observe the normal operation of all parts before starting the drill.
