How to ensure the reliability of the equipment when maintaining the concrete laser leveling machine?

  Concrete laser leveling machine is an indispensable and efficient construction equipment in modern construction projects. Its accurate leveling effect greatly improves the construction quality and efficiency. However, in the long-term use of the equipment, it is inevitable to encounter some common problems. This article will focus on several common after-sales problems of concrete laser leveling machine, combined with specific practical content, to provide detailed processing methods and suggestions, aiming to help users better use and maintain the equipment and ensure smooth construction. 1.   Equipment startup failure handling Equipment startup failure is one of the common after-sales problems of concrete laser leveling machine. When the equipment cannot start normally, first check whether the power plug is plugged in and whether the power switch is in the on state. If the power supply is normal, it is necessary to further check whether the motor is damaged or the line is short-circuited. At this time, you can use tools such as a multimeter to troubleshoot. If it is determined that the motor is faulty, you should contact professional after-sales personnel for repair or replacement. At the same time, you should also pay attention to the voltage requirements when the equipment is started to avoid startup failures due to unstable voltage. 2.   Laser system troubleshooting The laser system is the core component of the concrete laser leveling machine, and its stability and accuracy directly affect the leveling effect. The main manifestation of laser system failure is that the laser beam is unstable or cannot be emitted. When dealing with such problems, you should first check whether the laser transmitter is clean and whether there are any obstructions. At the same time, you should also check whether the position of the laser receiver is correct and whether the received signal is stable. If the laser system hardware is intact but there are still problems, you can try to calibrate or reset the laser system. If the problem still cannot be solved, you should contact professional after-sales personnel for inspection and repair. 3.   Hydraulic system maintenance and care The hydraulic system is an important part of the concrete laser leveling machine, responsible for driving the movement of components such as the leveling blade. The maintenance and care of the hydraulic system is essential to ensure the normal operation of the equipment. In daily use, the oil level and quality of the hydraulic oil should be checked regularly to ensure that the oil is clean and free of impurities. At the same time, it is also necessary to check whether the hydraulic oil pipe has oil leakage or damage, and if so, it should be replaced in time. In addition, regular replacement of the hydraulic oil filter and cleaning of the oil tank are also necessary maintenance measures. During use, the equipment should be prevented from overloading for a long time to avoid damage to the hydraulic system. 4.   Leveling effect adjustment method The leveling effect of the concrete laser leveling machine is affected by many factors, including the accuracy of the laser system, the angle and height of the blade, etc. When the leveling effect is not ideal, it can be improved by adjusting the relevant parameters. First, the parameters of the laser system, including the intensity and angle of the laser beam, can be adjusted to ensure that it can accurately reflect the height changes of the ground. Secondly, the angle and height of the blade can be adjusted so that it can better adapt to the ups and downs of the ground. In addition, the walking speed and leveling times of the equipment can be adjusted according to the specific construction requirements to achieve the best leveling effect. 5.   Solution to motor overheating Motor overheating is one of the common faults of concrete laser leveling machines, which may cause equipment performance degradation or even damage. There may be many reasons for motor overheating, such as poor heat dissipation, excessive load or internal motor failure. When the motor is found to be overheated, first stop using the equipment immediately and check whether the cooling system is working properly. If there is no problem with the cooling system, check the load of the equipment to ensure that it is not overloaded. At the same time, it is also necessary to check whether the wiring of the motor is loose or in poor contact to avoid overheating due to excessive current. If the above measures cannot solve the problem, contact professional after-sales personnel for repair or replacement of the motor. 6.   Replacement and purchase of wearing parts During the use of the Wenjie soil laser leveling machine, some wearing parts such as blades and filters will gradually wear or damage and need to be replaced regularly. When purchasing wearing parts, you should choose the brand and model that matches the original equipment to ensure that its performance and quality meet the requirements. At the same time, you should also pay attention to the installation and replacement methods of wearing parts to avoid damage to the equipment or affect the leveling effect due to improper operation. When replacing wearing parts, you should ensure that the power of the equipment is turned off and operate according to the instructions or the guidance of after-sales personnel. 7.   Cleaning and maintenance suggestions for the whole machine Maintaining the cleanliness and good condition of the concrete laser leveling machine is crucial to extending the life of the equipment and improving work efficiency. In daily use, the equipment should be cleaned regularly, including cleaning the dust and dirt on the surface, wiping the mechanical parts and electrical components, etc. At the same time, it is also necessary to pay attention to the regular lubrication of the lubrication parts of the equipment to reduce friction and wear. In addition, when storing the equipment, you should choose a dry and ventilated place to avoid moisture or direct sunlight on the equipment. For equipment that is not used for a long time, it should be started and inspected regularly to ensure that its performance is not affected. In short, the handling of common after-sales problems of concrete laser leveling machines requires comprehensive consideration of the characteristics of the equipment itself and the use environment and other factors. Through in-depth understanding and effective handling of equipment startup failures, laser system failures, wave pressure system maintenance and maintenance alarm adjustment, motor overheating problem resolution, replacement and purchase of wearing parts, and cleaning and maintenance of the entire machine, the stable operation and efficient construction of the concrete laser leveling machine can be ensured. At the same time, users should also strengthen communication and cooperation with professional after-sales personnel so that they can get timely and effective support and help when encountering problems.

    Using concrete curing blankets is a crucial step in protecting the ultra-flat floor and ensuring its long-term flatness and structural strength. Its main function is to maintain stable humidity and temperature during the hydration and hardening of the concrete, preventing shrinkage cracks and surface warping caused by excessive water evaporation. The following is a detailed operation guide based on industry standards and engineering practices. To achieve the best maintenance results, please follow the following steps: Steps Key operation Core purpose and precautions: 1. Timing for laying down After the surface is polished and leveled, proceed with the laying as soon as possible. Ideally, the covering should start within 10 to 15 minutes. Immediate moisturization: The moisture on freshly polished floors evaporates very quickly. Immediate coverage can lock in the surface moisture and prevent plastic shrinkage cracks. Note: If there is water on the floor, it should be carefully drained using a hose to prevent the surface from becoming too soft and being pressed into an indentation. 2. Laying method Complete wetting: Before laying, the contact surface (the gray side) of the ground and the maintenance blanket must be thoroughly sprayed with water to ensure the blanket is fully saturated. Front and back distinction: Lay the blanket with the white reflective side facing up and the gray wet side facing down, ensuring it closely adheres to the concrete. The white side can reflect sunlight and prevent the blanket from overheating. Close contact: Ensure that the blanket is in 100% tight contact with the concrete surface, without any air bubbles or wrinkles. Otherwise, the areas with poor contact will form dry spots. Overlap and fixation: Adjacent blankets need to overlap at least 15-30 centimeters (12 inches) and use sandbags or heavy objects to compact the edges and seams to prevent them from being blown away and ensure sealing. Covering the edges: The edges of the concrete slab and exposed formwork should also be covered with the blanket and kept moist. These areas are most prone to losing moisture. 3. Maintenance period management Continuous Moisture Retention: During the maintenance period, it is necessary to regularly check and re-wet the blanket to ensure it remains in a saturated state. Especially in hot, dry, or windy weather, it may be necessary to spray water multiple times a day. Maintenance Duration: At least 7 consecutive days of maintenance are required. For super smooth floors with high requirements or using high-performance concrete, it is recommended to extend the maintenance period to 14 days for better performance. Avoid Disturbance: During the maintenance period, it is strictly prohibited to walk on the blanket or stack any items on it to avoid damaging the floor. Whether to use the maintenance blanket and how to use it mainly depend on the ambient temperature during the construction process: Environmental conditions Why is a curing blanket needed? Specific approach: Cold weather (< 10°C) The hydration reaction is extremely slow and there is a risk of freezing. Ice crystals can damage the internal structure of the concrete, resulting in loss of strength. Use a thermal insulation blanket (typically a thick blanket filled with insulation material). Cover it immediately after the surface is polished, and keep it covered for 5-7 days. Remove it when the temperature is higher during the day (such as at noon) to prevent "thermal shock". Normal/Hot weather (10°C – 30°C +) The core is to prevent excessive evaporation of water. High temperatures, direct sunlight, and strong winds will quickly remove the water, causing shrinkage cracks. Strictly follow the above "three-step method", with the focus being on thoroughly pre-wetting the blanket and maintaining saturation. Facing the white reflective side upwards can lower the blanket temperature and reduce water evaporation. Strong wind and dry weather Wind is the primary factor that accelerates water evaporation. Even if the temperature is not high, it can easily cause rapid cracking on the surface. The blanket must be immediately covered and the edges must be tightly fixed to prevent wind from entering the bottom of the blanket and forming a "wind tunnel", which accelerates local water loss. Fast: Cover immediately after sanding. Wet: The blanket and the floor must be fully moistened. Tight: Ensure the blanket is tightly attached to the floor and the edges are sealed. Long: At least maintain for 7 days, preferably 14 days.   What is the current environmental temperature and weather conditions of your project?

Due to differences in technical characteristics between different brands and models of laser levelers, please consult the manufacturer for a suitable solution before actual operation. This reference document assumes no responsibility for any issues arising from failure to follow the manufacturer's instructions.    

First, the use of precautions1. When using, adjust and maintain according to the maintenance methods and various regulations described in the corresponding product manual. 2. It is not allowed to work at full speed and full load immediately after starting. It must be gradually transitioned from low speed and no load to high speed full load. 3. The fuel used in the diesel engine must be clean and should be allowed to stand for more than 72 hours. 4. The normal water temperature (75 °C ~ 95 °C) should be maintained for the diesel engine with radiator. When releasing the cooling water, you must first open the radiator cover (after the water temperature is lowered, then open it to avoid burns), and then unscrew the water discharge switch on the cylinder block. 5. The normal working oil pressure should be 0.2~0.4MPa. 6, the load must be strictly controlled, no overload is allowed, otherwise it will affect the reliability and service life of the diesel engine. 7. After the new or replacement injector, the medium-speed low-load running-in should be carried out, and the running-in time should not be less than 30 minutes. Before installation, the parts should be cleaned with clean kerosene or light diesel oil to remove anti-rust oil. 8. In the course of operation, if abnormal phenomena are found, stop in time. Second, fuel, oil and cooling water 1. Fuel Users should select the light diesel grades to be used according to the season and ambient temperature of the region. Recommendation: Use diesel fuel with a sulfur content below 0.5%. If the sulfur content is high, the oil change cycle will be shortened. Diesel filling and precautions Before the diesel engine is injected into the diesel engine, it must be allowed to stand for more than 72 hours, then the upper layer of clean diesel oil without water and impurities or filtered with silk cloth. Warning: (1) Do not fill fuel tank with fuel while the engine is running. (2) Do not smoke when filling the fuel tank with diesel fuel. (3) Use a clean oil pipe when refueling. Do not splash diesel oil outside. (4) Wipe off the spilled fuel. Materials that are fueled must be moved to a safe place. 2. Lubricating oil The oil must be selected according to the regulations. The viscosity of the oil is greatly affected by the temperature, and the user needs to correctly select the corresponding brand oil according to the ambient temperature. 3.cooling water should use clean soft water: rain, tap water or river water. If you use well water, spring water or other hard water with more minerals, you should add appropriate amount of softener, such as sodium carbonate (soda). The easiest way to do this is to boil the water and then precipitate it to remove impurities and use. In the cold winter, antifreeze can be added to the cooling system to prevent freezing. The most commonly used antifreeze is an aqueous solution of ethylene glycol (glycol) or alcohol. The use of antifreeze should be noted: Since the antifreeze has the characteristics of increasing volume with increasing temperature, when adding the cooling medium, the addition amount should be 5% to 6% less than the total capacity of the cooling system. Ethylene glycol – water-based antifreeze is toxic, special care should be taken when using it, and no entry is allowed. The boiling point of ethylene glycol is 194.4 ° C, so the water in the antifreeze is easy to evaporate, and the alcohol should be properly added after a period of use. If it is not anti-rust antifreeze, it should be removed regularly. When the diesel engine is used for a long time, the surface of the cooling water chamber will form scale, which will affect the heat dissipation of the diesel engine. For this reason, the scale should be cleaned regularly. The cleaning method is as follows: When cleaning, 25% hydrochloric acid solution can be injected into the water chamber and parked for 10 minutes. After that, the solution was drained and washed with water. If the scale is not removed, repeat it again Cooling water filling and precautions: (1) Fill the cooling water to the mark of the filling port. (2) Note that the drain valve is closed after the cooling water flows out from the drain valve. (3) Tighten the filler cap. (4) Start the engine and run to normal temperature until the thermostat is turned on (the cooling water pipe is obviously warmed up during the big cycle). (5) After the first operation, stop cooling and check the liquid level. Inspection and preparation before starting 1. When the new machine is started for the first time, carefully check the tight connection of each part, whether the attachment is complete, and whether the operating mechanism is flexible. 2. Check the oil level of the oil pan and the fuel injection pump between the upper limit mark and the lower limit mark of the oil scale. 3. Check the fuel storage capacity of the fuel tank. Turn on the fuel tank switch to allow diesel to flow to the fuel injection pump and remove air from the fuel system. 4. Check the battery and wiring. Check the electrolyte level in the battery. 5. Check the cooling system and add enough water. 6. In case of cold and freezing weather, the diesel engine should be placed in a cold-proof place. When working in the field, heat the oil sump and add two or three times of hot water to warm the diesel engine before starting. 7. The clutch should be in the separated state when the diesel engine starts. Startup After the preparation work before starting is completed and confirmed to meet the requirements, it can be started. The clutch should be disengaged when starting. The starting steps are as follows: 1. Push the lock switch to start the diesel engine. The starting time is less than 5 seconds each time to protect the starter and battery. After each failed start, stop for 1-2 minutes and start again. If the start fails three times in a row, you should find out the cause and troubleshoot before starting again. Once the diesel engine is started, the starter switch key should be released immediately and the lock switch should be returned to its original position. 2. Check the oil pressure immediately after starting. When the diesel engine is running at idle speed, the oil pressure should not be lower than 0.05MPa. After the newly assembled diesel engine is started for 5 minutes, stop the oil level of the oil pan and check if necessary, add oil so that the oil level is between the upper and lower marks on the oil scale. 3. Within one minute after starting the diesel engine, the water temperature gauge should be checked immediately to confirm that the cooling system is working properly. V. Operation After the diesel engine is started, the full-load operation should not be carried out immediately. The diesel engine should be heated in the idle mode at low speed and medium speed. 1. When operating, always pay attention to the oil pressure and cooling water temperature. When the speed is calibrated, the oil pressure should be 0.2~0.4MPa (2~4kgf/cm) 2. The temperature of the cooling water outlet is controlled at 80-90 °C. 3. When the diesel engine is running, always pay attention to observe whether the reading on the instrument panel is normal, whether there is abnormal sound. If it is found, it should be stopped immediately to check and find the cause and then allow it to start and run again. 4, always pay attention to the sealing of the oil and water connections, if there is a leak, it should be immediately removed. 5. The charging generator must be charged to the battery during operation, and the ammeter pointer points to “+”. 6. New or overhauled diesel engines are allowed to run at full speed at full speed after 50 to 100 hours of operation. Small roller parking 1. Remove the load and gradually reduce the speed to idling for 3 to 5 minutes before parking. 2. When the temperature is lower than 5 °C, if antifreeze is not used, the cooling water should be drained in time after parking to prevent cracking of the body. 3. After each stop, the faults found during operation must be discharged in time, and necessary inspections should be carried out. The diesel engine should be inspected and maintained frequently, and some sporadic faults should be eliminated in time to keep the diesel engine working properly and avoid serious faults. The necessary conditions for good economic returns. Daily maintenance of small road roller: (in combination with inspection preparation work), the driver usually carries out maintenance every day; check the fuel tank fuel quantity and add enough; check the oil level in the oil sump, when it is insufficient, it should be added; check and eliminate leakage and leakage Oil and gas leakage; check the stability of each accessory device; check the liquid level of the water tank.
