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.

    When the hydraulic oil temperature of your power trowel is too high, you can check and implement the following solutions one by one in the order from simple to complex: These steps can be carried out quickly on the construction site, aiming to control the situation immediately. Immediately stop the polishing operation, lift the polishing disc and let the equipment idle for a few minutes without load. This can quickly relieve system pressure and reduce heat generation. This is one of the most immediate methods. The vast majority of power trowel use air-cooled coolers. Please immediately use compressed air or a low-pressure water gun to blow and wash from the inner side to the outer side of the cooler fins to thoroughly remove the dust, cement powder lumps and debris adhering to them, ensuring smooth ventilation. After the machine stops, check the oil level gauge of the hydraulic oil tank. Low oil level (insufficient oil volume) can cause the oil pump to suck air and have insufficient cooling circulation, resulting in high temperatures. If the oil level is too high, the foam inside the fuel tank will be difficult to dissipate, which will also affect heat dissipation. Make sure the oil level is between the upper and lower marks on the dipstick. Move the equipment to a cool and well-ventilated place and avoid continuous operation under direct sunlight or in an environment with extremely high temperatures. If the problem persists or recurs after emergency measures are taken, a more in-depth inspection is required. Oil type: Ensure the use of anti-wear hydraulic oil of the grade and viscosity level specified by the equipment manufacturer. Excessively high viscosity will increase flow resistance and generate heat, while excessively low viscosity will intensify internal leakage, leading to a decrease in pump efficiency and heat generation. Oil quality: If the hydraulic oil has turned black, has a burnt smell or produces a large amount of foam, it indicates that the oil has oxidized and deteriorated, and its lubricating and heat dissipation performance has sharply declined. The oil must be completely replaced with new oil, and the oil tank should be cleaned and the hydraulic oil filter element replaced at the same time. Cooling fan: Check whether the motor driving the cooling fan is working properly and whether the circuit is intact. If it is belt drive, check whether the belt is loose, slipping or broken, and adjust or replace it in time. Upgrade cooling capacity: For old equipment or devices operating under extremely harsh conditions, if the original cooler's capacity is insufficient, it is advisable to consider installing a larger-capacity or independently driven air-cooled cooler. If the set pressure of the relief valve is too high or the valve core is stuck in the pressure relief state, it will cause high-pressure oil to continuously return to the oil tank through the relief valve. This is a common cause of a sharp increase in oil temperature. It is recommended that professional maintenance personnel use a pressure gauge to detect the system pressure and readjust the relief valve according to the specified value. If the valve core is damaged, it needs to be cleaned or replaced. Hydraulic pump: Internal wear of the hydraulic pump (such as wear of the plunger, gears or blades) can lead to severe internal leakage. High-pressure oil leaked inside the pump into the low-pressure area, generating a large amount of heat. It is usually accompanied by phenomena such as weak machine power, slow movement and increased noise. Professional personnel are required to conduct efficiency tests. After confirmation, maintenance or replacement should be carried out. Control valve group: The wear of the valve cores of each control valve (such as directional control valves) can also lead to internal leakage, causing local high temperatures. One can touch the surface of the valve block to feel if there are any abnormal hot spots to assist in the judgment. Prevention from the perspective of usage habits is fundamental. Arrange the construction rhythm reasonably to avoid the equipment running at full load for a long time without interruption. When the working conditions are particularly heavy, it is necessary to consciously arrange intermediate rest periods to allow the hydraulic system to "catch its breath" and cool down. Daily: Clean the exterior of the cooler after work. Weekly: Check the hydraulic oil level and quality. Every six months or according to the working hours: Replace the hydraulic oil and filter element regularly as recommended by the manufacturer. This is the most effective means to prevent system contamination and oil deterioration. Solving the problem of excessively high hydraulic oil temperature in the power trowel machine is a systematic process. Please follow the principle of "start from the outside to the inside, from the easy to the difficult" : Begin with external factors such as cleaning the cooler and checking the oil level, as these often solve most problems. If it is ineffective, further investigate the core parameters such as the quality of the hydraulic oil and the setting of the relief valve. Finally, complex maintenance such as internal leakage of hydraulic pumps and valve groups should be considered. Adhering to standardized operation and regular maintenance is the fundamental way to prevent such problems from happening.   Note: The parameters provided in this document are for reference only and are not mandatory.
