The advantages of laser leveling machine are revealed, don’t be convinced!

    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.

VANSE laser leveling machine training and after-sales service after purchasing the machine Shandong VANSE Machinery Co., Ltd. not only sells laser leveling machines, but also assists customers to complete projects and meet high-standard construction requirements. The so-called assisting customers to do projects means that our company's personnel will operate in the early stage of construction, and provide systematic training to the customer's construction personnel at the same time, which can be roughly divided into the following three steps: 1. The first job after the machine is sold is the pre-construction work. Our staff will explain the construction process, installation, and commissioning of the machine to the customer in detail: 1) After the base level is processed, the equipment of the laser leveling machine is adjusted, and the fixed reference level is drawn according to the original level point; the plastic film is laid, the steel mesh is bound (according to the design requirements), and the side formwork is supported; the laser transmitter is erected , introduce the floor level into the laser leveling machine according to the original benchmarking point. 2) Convey concrete, use commercial concrete, and transport it to the construction site with concrete trucks. 3) Scale calibration Use a hand-held receiver to check the floor elevation, introduce the elevation into the laser leveling machine, and adjust the reference point (±0.00) on the leveling machine. 2. Prepare well for the construction. During the construction, we will explain in detail the training and operation of the machine, the on-site construction, and the solutions to the problems that are easy to occur during the learning construction: 1) Concrete paving, within the effective construction range of the leveling head of the laser leveling machine, the concrete is initially leveled manually to a height of 1-2 cm higher than the floor level (the specific height depends on the slump of the concrete), and then the concrete The laser leveling machine completes the vibration, compaction and leveling work at one time. 2) Troweling and finishing. When the poured concrete reaches initial setting, it is polished by a trowel machine, and then manually troweled and finished. 3. After construction, we will explain to customers in detail the maintenance of the machine, different types of engineering construction methods, and different standard construction methods: 1) After each construction, you need to use the arm lift button to manually lift the machine head, and then exit the construction site. During this process, be careful not to push the machine when the vibration leveling part is in contact with the ground, otherwise it is easy to cause damage to the vibration plate. Moreover, after the construction is completed, it is necessary to flush the machine with a high-pressure water gun in time to prevent the water gun from being directly aimed at the mesh part of the fuselage for washing, so as to prevent water from entering the inside of the fuselage and causing problems such as short circuit of the machine circuit. 2) In addition, pay attention to the maintenance of the concrete floor. After the concrete is troweled, it is not allowed to move heavy objects on the floor for at least 7 days, and it should be kept in a moist curing state. In order to achieve a good maintenance effect, the surface should be covered to isolate the concrete from the outside. During the maintenance period, when the strength of the surface concrete does not meet the requirements, it is strictly forbidden to use people; the cutting seam should be in accordance with the design requirements, and the surface treatment of the floor should be completed. It is to be carried out later, that is, to ensure that it is carried out before the final setting of the concrete. The spacing, width, and depth of the cuts must meet the requirements of the design and construction specifications; the joints should be filled and protected until the concrete reaches its strength before it can be used. Our Shandong VANSE Machinery has a standard, that is, the customer's construction personnel are proficient in operating the machine, can do the on-site construction well, and complete the three training procedures to meet the standards of Party A and the customer's approval, and our company's staff can leave the site.

Concrete laser leveling machine is a device that uses laser technology for floor leveling. Its working principle is mainly based on laser measurement and control systems, combined with mechanical automation technology, to achieve high-precision and efficient floor leveling. During the specific work process, the laser leveling machine first emits a laser beam through the laser transmitter, which is projected onto the ground to be constructed and received by the laser receiver. The receiver then feeds back the received signal to the control system, and the control system adjusts the position and height of the leveling head based on the feedback signal to ensure that the leveling head always remains at the set elevation position for operation. The leveling head is the core part of the laser leveling machine. It integrates functional modules such as scraper, spiral and vibrating plate, and can complete the initial leveling, vibration and leveling of concrete at one time. During the leveling process, the role of the scraper and spiral is to evenly distribute the concrete, while the vibrating plate vibrates the concrete to achieve the desired flatness. At the same time, the laser leveling machine adopts a computer laser control system, which receives and processes laser signals through the laser receiver of the mechanical head to make real-time adjustments at a monitoring frequency of 10 times per second to accurately control the floor elevation. This allows the flatness of the entire floor to be accurately controlled and avoids manual errors and construction joint problems in traditional construction methods. In addition, in order to achieve large-area construction, laser leveling machines are usually equipped with automatic navigation systems or remote control systems to achieve automated and efficient construction. This construction method can not only improve construction efficiency and shorten the construction cycle, but also reduce manual operating errors and improve construction quality. To sum up, the working principle of the concrete laser leveling machine is based on the laser measurement and control system. By accurately controlling the floor elevation and flatness, combined with mechanical automation technology, efficient and high-precision floor leveling can be achieved.
