Key points for selecting concrete laser leveling machine

At present, the pace of economic construction is constantly accelerating, and the use of laser leveling machines is naturally increasing. With the increasing precision of road leveling, the use requirements and accuracy of laser leveling machines are also increasing. However, in order to save costs, we must pursue the extension of the service life of the product. In order to help you use the laser leveling machine better, the following article will mainly introduce some methods to extend its service life. 1. Before starting the laser leveling machine, check whether the hydraulic oil of the hydraulic station, the gear oil of the reduction box, and the transmission box are full. 2. Before starting the main motor, check and adjust the turning angle and adjust the working pressure of the hydraulic system, inject lubricating oil into each lubrication point, and check the operation of the mechanical transmission part of the leveling machine to make it flexible in transportation and installation. 3. Operators should wear labor protection supplies and must not leave their posts or go to other posts after starting the machine. 4. After the oil temperature and oil pressure of the hydraulic station are stable, the upper straightening roller is lifted to the initial position, and the material is fed manually. After the plate is sent through the straightening roller, the upper straightening roller is pressed down and clamped. 5. Start the main motor of the laser leveler. The plate moves forward and is straightened at the same time. The motor stops, the straightening roller stops straightening, the upper straightening roller is lifted, and the straightened steel pipe is sent out. 6. The motor of the laser leveler stops, the straightening roller stops straightening, and the next straightening program instruction is repeated. 7. After stopping, turn off the main power supply and do not change the program controller at will. 1. The connection between the supercharger and the intake and exhaust pipes of the laser leveler must be tight and cannot leak. If there is a leak between the exhaust pipe and the exhaust turbine, the efficiency of the supercharger will be greatly reduced, and the exhaust temperature of the diesel engine will rise sharply, damaging the valve and supercharger. 2. Before starting a new machine, fill the supercharger and supercharger oil filter with clean oil to ensure that the supercharger bearing can be lubricated as soon as the diesel engine starts. After the car has traveled 8000 to 10000 km, the supercharger oil filter element must be replaced. 3. Before the diesel engine of the laser leveling machine is shut down, it should be operated at idle speed for 3 to 5 minutes to reduce the speed and temperature of the supercharger, and monitor the sound of the supercharger operation. If any abnormality is found, the machine should be stopped for inspection. If the supercharger rotor is not flexible and there is a jamming or wear sound, it must be sent to a qualified maintenance station for repair. 4. After the laser leveling machine works for every 500 hours or 30,000 km, the clearance on the supercharger rotor shaft should be checked, and the dust and carbon deposits on the compressor turbine shell and rotor blades should be removed. At this time, the turbocharger should be removed from the diesel engine and the metal gasket between the supercharger exhaust pipe should be replaced. Mechanical methods are not allowed to remove the deposits on the rotor parts, but gasoline or other detergents for cleaning aluminum parts should be used. In order to help everyone better use the laser leveling machine, the above content mainly introduces methods to improve the service life of the equipment, and I hope it will be helpful to you. I also hope that you can continue to pay attention to our company's official website, where you will see more news about the leveling machine.
