What should I do if the speed of rock drilling is reduced during the operation of the YT28 rock drill?
YT28 pneumatic leg rock drill has stable and reliable performance. If it is used correctly, there will be few failures. If there is a reduction in the speed of rock drilling during work, there may be several reasons:
First, the working pressure is low, exclusion method:
1, Reduce the number of benches for rock drills or other gas-consuming equipment.
2, eliminate pipeline leakage.
3, reduce the hose length (within 20 meters), replaced the small diameter and valves.
Second, poor lubrication, removal methods:
1. Lubricating oil is too sticky and dirty, and the oiling device cannot be used for oil replacement. The oil should be replaced according to the regulations.
2. The oil line of oil injector should be repaired immediately.
3, non-lubrication is forbidden or lubricated with grease.
Third, there is water in the machine, exclusion method:
1, water pressure is too high to produce inversion, take pressure reduction measures.
2, water in the air pressure is too large, should be installed in the pipeline "wind bag."
3, water injection system failure, air and water mixing, and immediate maintenance.
4, the water needle breaks or the drill rod hole is blocked and replaced immediately.
5, muffler cover ice, immediately eliminate.
Fourth, lack of air leg thrust, exclusion methods:
1, seals YX, sealing sleeves, cross-arm O-rings, etc. are damaged and replaced in time.
2. The frame body and the outer tube are loosened, causing the upper and lower chambers to deflate and tighten in time.
3, The handle trigger and the reversing valve are stuck and should be repaired in time.
Fifth, the size of the solder tail is improper, and the remedy method should be corrected if the solder tail length is plus or minus 1 mm and the length is too long or too short.
Six, the main parts failure, troubleshooting methods: timely replacement of failed parts.
