1) When the rock drill jack hammer is used, the compressed air at the air inlet of the rock drill jack hammer is required to be dry, and the wind pressure should be maintained at 500kPa, and the minimum should not be less than 400kPa; clean soft water is required. Some lubricating oil, turn off the water and run dry for a while. 2) Clean and reinstall when starting a new machine.
After reinstalling, drive an empty car to check whether it is running normally. But the empty time cannot exceed 2~3min.. If the time is too long, the temperature of the air cushion area of the cylinder is too high, and the phenomenon of cylinder grinding is prone to occur. Do a good job of pipe cleaning and routine disassembly and maintenance work. The machine is always in good working condition, and you should always pay attention to adding lubricating oil, and it is strictly forbidden to operate without oil. 4) In operation, pay attention to opening the air and then boiling the water, and turning off the water first.
Wind, and pay attention that the water pressure should be lower than the wind pressure to prevent water from flowing back into the cylinder of the rock drill jack hammer, destroying the normal lubrication of the machine, and affecting the normal operation of the machine. When the rock drill fiber clamp rotates very slowly, the pressure regulating valve should be used to reduce the axial retraction force of the air leg immediately. If the fiber rod is not rotating, if the axial thrust of the air leg is reduced, the rock drilling should be stopped immediately, and the rock drilling jack hammer should be eliminated after the fiber jam is eliminated. 6) Always observe the powder discharge of the machine. Injection of water injection, or dry eyes.
When the telescopic rock drill is working upwards, pay attention to the magma flowing down the drill not close to the fiber sleeve. The distance between them must be at least 20mm. Otherwise, the blowing force is insufficient. At this time, check whether the blowing holes on the fiber sleeve are unobstructed according to the procedure. When the telescopic rock drill jack jammer is working upwards, in addition to observing the general safety technology for rock drilling, special attention should be paid to the sudden breaking of the drill to prevent accidents at work.
It is strictly forbidden to run at full speed for a long time, and the trolley should be driven when pulling the fiber. 9) After the work is completed, close the water valve and let the rock drill jack hammer run idle for a short time with small wind to remove the accumulated water and prevent rust. For the guide machine, after finishing a fiber, stop the wind, and then reverse the unloading of the fiber tail. When reversing the fiber unloading, respond to wind. If it changes from the forward rotation to the reverse rotation immediately, a great impact will be generated due to inertia, which will reduce the service life of the spiral rod of the rotating claw. When drilling rock and stopping use for a long time, it should be removed and washed in time, coated with anti-rust oil, and stored in a dry place.
