CIR110A DTH Hammer Common Troubleshooting Methods
| Malfunction | reason | Method of exclusion |
| Air supply does not impact | 1. There is foreign matter at the disc valve and the check valve is stuck. | Disassemble the impactor for cleaning and inspection. |
| 2. The lubricating oil is too viscous to stick the piston. | Open the check valve, add a small amount of kerosene or petrol flush, and then replace the thinner lubricant. | |
| 3. After the drill bit sticks out, it will snap to the front joint and cannot be reset. | Remove the drill head for maintenance. | |
| 4. Poor lubrication, piston and cylinder bite. | Dismantle and overhaul, replace parts when necessary, and improve lubrication conditions. | |
| 5. Install wrong or missing parts. | Reassemble according to the structure diagram | |
| Shockless | 1. The rubber ring is damaged, the adjusting pad and the gasket are not pressed. | Replace apron, increase gasket |
| 2. Severe wear of pistons, cylinders, etc. | Replace parts |
CIR110A Downhole Drill Impactor Operation Precautions:
1. In normal rock drilling conditions, the impactor is serviced and
cleaned and reassembled every 200 hours of operation. Drilling
holes or mud slagging is performed every 100 hours.
2. The lubrication of the impactor is achieved through the oiling
device on the main engine. Therefore, it is necessary to ensure
that the oiling device is filled with oil before the start of each
shift, and there is still a surplus before the next shift begins.
The lube oil is mechanical oil No. 20 in summer and No. 5-10
mechanical oil in winter. Before the impactor is installed on the
drill pipe, the exhaust valve is operated to remove the debris in
the drill pipe and check whether there is oil in the drill pipe.
Check the impact device after connecting.
3. The impactor and the drill rod must not be reversed in the hole
to prevent accidents. In the process of drilling down the hole, if
you want to stop drilling, you should not stop the air supply to
the impactor immediately. You should lift the drill and blow it,
and stop the gas supply when there is no more rock and rock powder
in the hole. , Then stop turning.
Welcome to inquire, we will do our best to provide you with the
required product information information.
