As laser leveling machines become more and more widely used, minor problems encountered during construction also arise. After investigating and summarizing the problems encountered by customers during use, we found that these problems are basically caused by improper operation. Here is a brief summary.
1: The leveling head slides by itself
Possible reasons: The hydraulic lock valve core of the laser control system is dirty, or the O-ring of the valve core is damaged and cannot seal.
Solution: First clean the surface of the valve group. Lower the leveling mechanism so that the cylinder is not stressed. Remove the hydraulic lock and check if there is any stolen goods inside. If there is any stolen goods, throw it out with force. Check whether the sealing ring is damaged and replace it if it is damaged.
2: The lifting cylinder is not sensitive
Possible reasons: The proportional valve core is dirty, or the valve core is damaged, or there is air in the oil pipe.
Solution: Remove the proportional valve core and see if there is dirt inside the valve core, throw it out if there is any; open the lift switch and see if the valve core moves normally. Failure to move, one-way movement or slow movement indicates that the proportional valve is damaged. Needs to be replaced. Without dismantling the valve core, start the machine, turn on the lift switch of the oil cylinder, and check whether the oil pipe vibrates greatly. If it is larger, tap the pipe gently with the lift switch open to eliminate the gas in the pipe.
3: The water pump does not produce water
Possible reasons: There is no water in the pump and negative pressure cannot be formed; dirt enters the water pump and the water pump is clogged.
Solution: Add water to the water inlet pipe or connect the water inlet pipe directly to the faucet; if dirt enters the water pump, first connect the water inlet pipe to the faucet, remove the water gun, and turn on the machine to see if the stolen goods can be flushed out. If that doesn't work, remove the water inlet valve bolt and clean out the dirt.
