How Does The Concrete Laser Leveler/ Leveling Achieve Such Excellent Leveling Effects?

Large area floor laser leveling machine leveling construction method 1. Laser transmitter The laser transmitter is one of the important components of the large-area floor laser leveling machine. It is responsible for emitting laser beams and providing positioning and navigation benchmarks for the leveling machine. The laser transmitter should have the characteristics of high precision, high stability and long life to ensure the accuracy and reliability of leveling construction. When selecting a laser transmitter, factors such as its power, wavelength, and beam quality should be considered to meet different construction needs. 2. Work head The leveling head is the core component of the large-area floor laser leveling machine. It is responsible for leveling and compacting concrete materials to form a smooth and flat floor. The design and manufacturing quality of the smoothing head directly affects the quality and appearance of the floor. The smoothing head is generally composed of a scraper, a pressing plate, a motor, etc. It has a variety of working modes and adjustment functions, and can be selected and adjusted according to different concrete materials and construction requirements. 3. Engine The engine is the power source of the large-area floor laser leveling machine and provides power for the operation of the leveling machine. The choice of engine should be based on the specifications and construction needs of the leveling machine. Generally, a diesel engine or an electric motor is used. Engine performance parameters such as power, fuel consumption, noise, etc. are also important factors in selection. 4. Control Panel The control panel is the control center of the large-area floor laser leveling machine. The operator can control the operation of the leveling machine and switch between various working modes through the control panel. The control panel generally has multiple functions, such as start, stop, speed adjustment, direction control, etc. It can also display the working status and fault information of the machine. The design of the control panel should be concise and clear, making it easy for operators to quickly grasp and operate. 5. Auxiliary equipment Large-area floor laser levelings also require some auxiliary equipment such as concrete mixers, transport trucks, water pumps, etc. to complete the entire construction process. The selection and use of these auxiliary equipment should be based on actual conditions to ensure the smooth progress of construction and improve construction efficiency.

    The hydraulic system of the concrete laser leveling is its "heart" and "muscle", responsible for driving all key actions such as the lifting, vibration, movement of the leveling head and the extension and retraction of the boom. A scientific and rigorous maintenance plan for the hydraulic system is the core to ensuring the reliability, accuracy and long service life of the equipment. The following is a well-structured and highly operational correct maintenance plan for the hydraulic system of a concrete laser leveling: More than 70% of the faults in the hydraulic system are caused by oil contamination (particles, water, air) and excessively high oil temperature. Therefore, the maintenance plan should revolve around "keeping the oil clean and cool". Oil level check: When the equipment is parked on a level ground and all oil cylinders are retracted, check the oil level gauge of the hydraulic oil tank to ensure that the oil level is between the upper and lower limits marked. Low oil level can cause the pump to run dry, the system to overheat and components to be damaged. Visual inspection Leakage inspection: Quickly inspect the oil pump, valve block, cylinder piston rod, all pipe joints and hose surfaces for visible oil leakage or dripping. Pipeline inspection: Check for any abnormal bulges, wear, cracks or friction with adjacent components in the hydraulic hose. Start preheating: In cold weather, after starting the engine, it should be run at medium to low speed without load for 3 to 5 minutes to allow the hydraulic oil to circulate and heat up, improve fluidity, and prevent dry grinding of components. Cleaning and inspection: After the operation, check whether the oil filling port of the hydraulic oil tank, the vent valve (breather), and the surface of the hydraulic components are contaminated by cement mortar. Clean them in time to prevent contaminants from entering the system. Temperature perception: Before shutting down, use the back of your hand to sense whether the temperature of the fuel tank and the main valve blocks is abnormally hot to the touch (usually not exceeding 80℃). Continuous high temperatures will accelerate the oxidation and deterioration of the oil. This is the main body of the maintenance plan. It must be carried out strictly in accordance with the intervals in the manufacturer's manual and detailed records must be made. Maintain the project Period/Frequency Specific operations and standards Hydraulic oil replacement First replacement: 200 to 500 hours after a new machine or major overhaul. 1. Change the oil while it's still hot: Perform this when the equipment has just been shut down and the oil temperature is still hot. Regular replacement: Every 1,000 to 2,000 working hours or once a year (whichever comes first). 2. Thorough empting: Drain the old oil from the fuel tank and oil lines. If necessary, flush with fresh oil. The cycle needs to be shortened under harsh working conditions. 3. Clean the fuel tank: Use a non-fibrous cloth to clean the inner wall of the fuel tank and the magnetic drain plug. 4. Strict oiling: Add new hydraulic oil of the specified grade and viscosity level to the prescribed oil level through a high-precision filter. Replacement of the oil suction/return oil filter element Every 500 hours or simultaneously with each oil change. When replacing, pay attention to cleaning the area around the filter element seat to prevent dirt from falling in. 2. Never reuse the filter element after cleaning it. High-pressure pipeline filter (if any) Alarm according to the clogging indicator on the filter, or as stipulated in the manual (usually synchronized with the oil change cycle). Timely replacement and checking the type of residue on the filter element can help determine the internal wear condition of the system (for example, if there is a lot of metal shavings, there may be abnormal wear of components). Hydraulic oil quality testing Every 6 months to 1 year (applicable to high-value or high-intensity usage equipment). Samples are sent to a professional laboratory for oil spectral analysis to detect water content, contamination degree, acid value and metal wear particles. This is the most effective means of predictive maintenance, which can detect potential faults in advance. System tightening and inspection Monthly or every 250 hours. 1. Inspect and tighten all pipe joints, flanges and valve block installation bolts (in accordance with torque requirements). 2. Check all the piston rods of the oil cylinders for any scratches, rust or bends. Minor scratches should be repaired immediately with an oilstone. 3. Check the pre-charge pressure of the accumulator (if any). Cooling system cleaning Weekly or depending on the cleanliness of the environment. Clean the fins of the hydraulic oil radiator to ensure there is no blockage from dust, willow catkins, cement powder, etc., to guarantee the heat dissipation efficiency. This is the key to controlling the oil temperature. Overloading is strictly prohibited: Avoid the leveling machine operating at its maximum load for a long time, as this will cause excessive system pressure and a sharp increase in oil temperature. Avoid shock: Operate the control handle smoothly to reduce the shock load on the hydraulic system. Cylinder protection: During operation, pay attention to protecting the piston rod to avoid direct impact or scratches from concrete or crushed stones. Proper parking: When parked for a long time, all cylinders (especially the exposed piston rods) should be retracted to reduce corrosion and deformation. High-temperature environment: Enhance the cleaning of the radiator. Consider using hydraulic oil with higher viscosity (as recommended in the manual), and add auxiliary cooling if necessary. High humidity/water environment: Strengthen the inspection of oil level and water content in oil products, and keep the vent valve of the oil tank dry. The replacement cycle of the filter element can be shortened. In extremely cold environments: Use low pour point hydraulic oil. The equipment should be parked in a warm warehouse and fully preheated before startup. Park the equipment in a dry room and completely retract all the oil cylinders. Fill the fuel tank to the brim to reduce the formation of condensation on the inner walls. Start the engine every month and let the hydraulic system run idle for 10 to 15 minutes to lubricate all components and remove moisture. Slow and weak operation: It may be due to low oil level, pump wear, or malfunction of the main relief valve. Abnormal system noise (pump beeping) : It may be due to clogged oil suction filter element, excessively high oil viscosity, pump suction or cavitation. Abnormal increase in oil temperature: cooler blockage, severe internal leakage, improper oil level, and the set value of the relief valve being too high. Cylinder crawling or shaking: Air inside the system, leakage from the cylinder, or oil contamination causing the valve core to get stuck. Stop the machine immediately for inspection: If any of the above abnormalities occur, stop the machine immediately and start checking from the simplest aspects such as oil level, filter element, and leakage. Eliminate operating while faulty: Hydraulic system failures can deteriorate in a chain reaction, and minor issues can quickly turn into major overhauls. Professional maintenance: Complex operations such as pressure adjustment and disassembly of pumps and valves should be carried out by professional maintenance personnel. Before disassembling any hydraulic components, the system pressure must be completely released. Strictly adhere to the cycle: execute by the hour or calendar, and establish maintenance logs. Oil product management is at the core: only specified oil products are used, strictly filtered, and regularly replaced and tested. Cleanliness is the top priority: keep the oil clean, the refueling process clean, and the radiator clean. Pay attention to detailed inspection: Daily visual and tactile checks can detect most early problems. Equal emphasis on operation and maintenance: Standardized operation is the fundamental way to prevent abnormal stress in the hydraulic system.
