Common failures and solutions of gasoline rock drill

The  gasoline rock drill is one of the important rock drilling equipment. Let's take a look at the causes and solutions of these failures with the pace of the editor.

1. Failure caused by low working pressure of  gasoline rock drill

The  gasoline rock drill calculates whether the compressor pipeline is overloaded. If it is overloaded, the number of working machines can be reduced according to the actual situation, or other gas-consuming operations can be reduced. Eliminate the factors that cause the pressure drop due to pipeline leakage, check and replace the leakage pipeline and joints. The length of the gas hose should be controlled between 10m-15m. Check and replace the small gas pipe diameter and valve switch. Avoid reducing line pressure.

2. Broken water needle of  gasoline rock drill

The cause of the water needle failure: the center hole of the shank tail is not right, the matching gap between the shank tail and the shank is too large, the water needle is too long, and the shank tail does not meet the standard standards, so I want to buy a good internal combustion rock drill to come to China Coal. Remedy: If the center hole of the drill is not correct, replace the drill; if the matching gap between the drill and the drill sleeve is too large, the drill sleeve is worn from the opposite side of the hexagon to 25mm, which does not meet the standard. Otherwise, the water needle will not only be broken by mistake, but the drill will be easily damaged. , Should be replaced in time; if the water needle is too long, it should be repaired in time, if the drill does not meet the standard, it should be repaired according to the standard.

3. The gas-water linkage failure of the  gasoline rock drill occurred 

The main reasons for the failure of the air-water linkage failure are: excessive water pressure, blockage of the air and water channels, failure of the water injection valve spring, air leakage, water leakage, rubber ring failure, and corrosion of parts in the water injection valve. Remedy: If the water pressure is too high, pressure reduction measures should be adopted; the air and water channels should be blocked, and the clogged debris in the small holes of the air and water channels should be removed; if the water injection valve spring fails, the spring should be replaced or repaired in time; water leakage, air leakage or glue If the ring fails, the seal should be replaced or repaired; the parts in the water injection valve should be rusted and cleaned, and the failure caused by more than two reasons should be comprehensively treated.
