How to lift the air leg of the rock drill - how to solve the fault of the air leg of the rock drill
The rock drill has its own fixed air leg control system. During use, we can use the air leg regulating valve to adjust the thrust of the air leg according to the needs of the site, which can increase or decrease the thrust of the air leg; Among them, if the propulsion length of the air leg of the rock drill cannot meet the rock drilling depth, when it is necessary to move the air leg and transposition for two propulsions, you only need to pull the trigger to push the reversing valve, and the gas leg of the rock drill will quickly retract for transposition.
Of course, the possibility of failure of the air leg control system of the rock drill cannot be ruled out. When the rock drill does not respond when using the above method, we should check whether there is insufficient thrust of the air leg of the rock drill and the failure of the air leg of the rock drill to expand and contract. Then when this happens How should this situation be solved? We should proceed from the following six aspects:
1. The plastic bowl of the air leg is worn or loose, replace or reassemble.
2. The frame body is loose from the outer tube, causing air to escape from the upper and lower chambers, so the frame body must be tightened.
3. Seals are damaged or missing and should be replaced.
4. The expansion ring of the pressure regulating valve is worn out and cannot be fixed, so it should be replaced.
5. The pressure regulating valve is worn or the reversing flange elastic ring (YT24-3.01) is lost, which causes the positioning of the reversing valve to deviate, and parts should be replaced and supplemented.
6. The trigger is worn, the stroke is not enough during compression and reversing, and the air leg is not easy to retract. The trigger should be replaced in time.
The above is the detailed solution for how to raise and lower the air leg of the rock drill. I hope you can carefully identify it during use, improve work efficiency, and do a good job of safety protection.
