What is the leveling effect of the laser leveling machine?

    Lubrication and maintenance of the power trowel is the core work to ensure the long-term stable operation of the equipment and prevent sudden failures. The key lies in "using the right oil, finding the right time, doing it on time and using the right method". The following are the specific key points 1. Power trowel the main shaft bearing – the most crucial and frequent Location: The center drive shaft of the pan, usually with 1-2 grease nozzles. Lubricant: High-temperature resistant (≥120℃), extreme pressure lithium-based grease (such as molybdenum disulfide grease) must be used. Ordinary butter must not be used. Method and Cycle It must be carried out after each shift's work (working for 8 to 10 hours). Thoroughly clean the grease nipple and its surroundings. Add until the new grease overflows: Use a grease gun to add until the clean new grease is completely squeezed out from the edge of the bearing seal ring from the old grease. Wipe off the excess grease. Objective: To remove metal shavings and impurities produced by internal wear and ensure that the bearing cavity is filled with new grease. 2. Gearbox/reducer Lubricant: Select the specified type of gear oil (such as SAE 80W-90 GL-4) strictly in accordance with the instructions. Check: Every day, check through the oil window or dipstick whether the oil level is between the upper and lower marks. Replacement cycle First replacement: After the new machine has been running for 20 to 30 hours, remove the running-in debris. Regular replacement: Replace it every 300 to 500 hours of operation or annually thereafter. Key point: Oil change should be carried out when the oil temperature is still hot after the equipment is shut down to ensure that the old oil is completely drained. 3. Traveling wheels and steering mechanism Location: Walking wheel bearing, steering tie rod ball joint, hinge point. Lubricant: The high-temperature resistant lithium-based grease as mentioned above. Cycle: Every 50 hours of operation or once a week. Method: Clean each grease nozzle and add grease until new grease overflows from the gaps. 4. Engine (Gasoline model) Engine oil inspection and replacement Check the oil dipstick before starting every day to ensure the oil level is normal. First replacement: After running for 20 to 30 hours. Regular replacement: Every 100 hours or every quarter. The cycle should be shortened in harsh environments. Air filter maintenance: Regular cleaning. For oil bath air filters, use the dedicated air filter oil as per the instructions. Cleaning first: Before filling, be sure to clean the oil nozzle, oil cap and the surrounding area to prevent sand, dust and concrete particles from being brought into the interior. Strict specifications: Different parts should use the specified type of grease/oil products. They must not be mixed or substituted. High-temperature grease is the "life-saving oil" for the main shaft bearings. Squeezing out the old grease: For bearing lubrication, "adding until the new grease overflows" is a necessary step. This is the only effective way to remove contaminants and ensure the lubrication effect. Precise cycle: The maintenance cycle is mainly based on the operating hours (rather than calendar time) and is strictly recorded. Error: Lubricate the main shaft bearings with ordinary grease. Consequence: The grease melts and leaks away at high temperatures, the bearings dry grind rapidly and burn out at high temperatures, leading to the failure of the entire machine. Error: Only add fat without squeezing out the old fat. Consequence: Metal shavings accumulate in the bearing cavity, forming abrasives, accelerating wear, and causing abnormal noises and jamming. Error: Ignoring the oil level in the gearbox and its replacement. Consequence: Insufficient lubrication of gears and bearings leads to pitting corrosion, broken teeth, and scrapping of the reducer. Error: The spilled grease was not cleaned up after lubrication. Consequence: Grease adsorbs dust to form hard scale, which damages the sealing performance of the oil seal and makes it easier for impurities to invade. Create a lubrication chart: Make a simple chart of all lubrication points, oil types and cycles of the equipment, and stick it in a prominent place on the equipment. Equipped with dedicated tools: Use high-quality grease guns and dedicated oiling nozzles to ensure sufficient filling pressure. Record: After each maintenance, record the operating hours and maintenance items to form a traceable maintenance file. Long-term storage and maintenance: Before the equipment is out of use, thoroughly lubricate all lubrication points once. The engine oil should be changed or stabilizers added as per regulations to prevent internal rusting. The lubrication and maintenance of a power trowel essentially involve the continuous confrontation with its harsh working environment (heavy load, high temperature, and much dust). By grasping the two key points of "post-shift high-temperature grease extrusion lubrication" for the main shaft bearings and "regular oil change" for the gearboxes, the vast majority of major mechanical failures can be avoided, significantly extending the service life of the equipment.   Note: The parameters provided in this document are for reference only and are not mandatory.

  – Material inspection: Make sure that the mix ratio of concrete meets the construction requirements. For laser leveling machine construction, the slump of concrete is generally recommended to be between 12 and 18 cm, so that the concrete has good fluidity and is convenient for the leveling machine to operate. For example, in the construction of large factory floors, the slump of concrete should be tested in advance to avoid affecting the leveling effect due to inappropriate slump. – Base treatment: The ground base needs to be solid and flat. If there are uneven areas on the base, the thickness of the concrete will be uneven, affecting the final flatness of the ground. Therefore, before construction, the base should be cleaned and repaired, debris, dust, etc. should be removed, and potholes should be filled.   – Vibration link: After the concrete is laid, before using the laser leveling machine, you can use a vibrating rod for preliminary vibration to make the concrete more compact. But pay attention to the vibration time and depth to avoid excessive vibration causing concrete segregation. During the vibration process, it should be coordinated with the construction sequence of the laser leveling machine. Generally, the leveling operation should be carried out as soon as possible after vibration. – Leveling operation: When the laser leveling machine is used for concrete floor construction, the parameters of the equipment should be adjusted according to the design elevation and slope requirements of the ground. During the construction process, the walking speed of the machine should be uniform, avoiding too fast or too slow. Too fast speed may cause insufficient flatness of the ground, and too slow speed will affect the construction efficiency. At the same time, pay attention to the height and angle of the scraper to ensure that the concrete surface is flat and smooth.   – Moisturizing maintenance: After the concrete is leveled, moisturizing maintenance should be carried out in time. Plastic film, straw mats, etc. can be covered on the surface to prevent the concrete from cracking due to excessive evaporation of water. The maintenance time is generally not less than 7 days. In hot weather or dry environment, the maintenance time should be appropriately extended. – Temperature control: The temperature of asphalt material is crucial to the construction quality. During construction, the temperature of hot-mix asphalt mixture should meet the requirements of construction specifications. Generally, the exit temperature of ordinary asphalt mixture is between 140 and 165℃. If the temperature is too low, the asphalt mixture will become viscous, which is not conducive to the construction of the leveling machine; if the temperature is too high, it will accelerate the aging of asphalt. – Base treatment: Similar to concrete floors, the base of asphalt floors also needs to be solid and flat. At the same time, the base must be kept dry, because if there is moisture in the base, after the asphalt is paved, the evaporation of moisture will cause hollowing and cracking problems in the asphalt pavement.   – Paving uniformity: During the asphalt paving process, the asphalt mixture must be spread evenly. When the laser leveling machine is in operation, pay attention to controlling the pressure of the scraper to avoid excessive pressure that causes excessive extrusion of the asphalt mixture, affecting its density and surface flatness. – Joint treatment: In asphalt floor construction, joint treatment is a key link. When using a laser leveling machine for multi-width paving, the longitudinal joints between the two widths must be handled well. Generally, the hot joint method can be used, that is, a certain width (generally 10-20cm) of the first paved asphalt mixture is left unrolled for the time being, as the reference surface for the later paving part, and then the joint is leveled with a leveler so that the two asphalt pavements can be well connected.   – Compactness inspection: After the asphalt floor construction is completed, the compaction of the ground should be checked. Nuclear density meters and other equipment can be used for testing to ensure that the compaction meets the design requirements. If the compaction is not enough, the asphalt floor will cause rutting and other diseases during use. – Stone selection and processing: Select stones with uniform size specifications and good flatness. Before paving, the back of the stone should be cleaned to remove dust, impurities, etc., and appropriate back coating can be performed to enhance the bonding between the stone and the base. – Base preparation: The base needs to have sufficient strength and stability, and cement mortar is generally used as the base material. The flatness error of the base layer should be controlled within a small range to provide a good foundation for stone laying.   – Laying accuracy: When using a laser leveler to assist in laying stones, the laying height and levelness of the stones should be accurately controlled. Since the stone itself is heavy, the leveler should be careful to avoid collision with the stone during operation to prevent the stone from breaking or shifting. For large-sized stones, multiple people may be required to cooperate in the construction and use the leveler for fine-tuning. – Use of bonding materials: When laying stones, the bonding materials (such as cement mortar or special stone glue) should be applied evenly and the thickness should be moderate. The laser leveler can be used to check the flatness of the stone after laying. For uneven stones, adjustments can be made before the bonding materials solidify.   – Cleaning and protection: After the construction is completed, the stains and bonding material residues on the stone surface should be cleaned in time. And the stone surface can be protected, such as applying protective agents, to prevent the stone from being polluted and eroded, and extend the service life of the stone floor.
