Energy Consumption, Energy Saving And Environmental Protection Performance Of Concrete Laser Leveling Machine

As we all know, summer is the time of year when the temperature is particularly high. Like winter, laser leveling machines are used in harsh environments. If the maintenance is not in place, coupled with the high temperature, the laser leveling machine is likely to have various problems. Therefore, when using the laser leveling machine in summer, special attention should be paid to the maintenance and maintenance. So how should the laser leveling machine be maintained and maintained in summer? 1. In summer construction, the engine should be prevented from overheating first. Under normal circumstances, the engine temperature should not exceed 95°. If the temperature is too high, a relatively cool area should be selected for shutdown and cooling. At the same time, the engine hood can be lifted for ventilation and heat dissipation. 2. The cooling water volume should be checked in time. When the water radiator reaches 100°, do not rush to add cooling water. Instead, the engine should be shut down immediately to cool down the engine at idle speed, and then add coolant. 3. The construction temperature is high in summer. Check the tire pressure and tire temperature of the laser leveler frequently. If the tire temperature is too high, stop the machine in time and place it in a cool place to cool down. Remember to use the wrong method of deflation or pouring cold water to cool down. 4. Check the liquid level of the laser leveler battery frequently, add distilled water in time, dredge the vents, pay attention to the density of the electrolyte, and maintain a good charging state. 5. Prevent the laser leveler engine from deflagration. Before entering the summer, the carbon deposits in the combustion chamber, valve top and other parts should be thoroughly removed to maintain good heat dissipation and normal compression ratio; and check and adjust the fuel supply advance angle to prevent engine deflagration. 6. Check the temperature of the hydraulic oil and hydraulic transmission oil frequently. If the temperature is too high, stop the machine for rest. Do not exceed high temperature operation. 1. Quality. When choosing a laser leveler, you should pay attention to the quality. If the quality of the laser leveler is not good, problems may occur during work, which may delay the construction period and the loss is immeasurable. 2. Operation effect. When purchasing a laser leveler, you should conduct an on-site inspection. If it is inconvenient, you can ask the manufacturer to provide some photos for reference. 3. After-sales service. When purchasing a laser leveler, you should also pay attention to the after-sales service. When purchasing a laser leveler, you should identify regular and professional manufacturers, and verify the manufacturer's technical capabilities and after-sales service. Only regular manufacturers can guarantee the performance of the machine, solve problems in time when the machine has problems, and extend its service life. It can be seen that when using equipment in extreme weather, you must pay special attention to its maintenance content, so as to ensure the smooth operation of the equipment. After reading the above article, I hope that everyone will pay attention to the above points when maintaining the laser leveler in the future. Thank you for your reading and support.

    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.

    Adjusting the operating parameters of the power trowel machine for different concrete ratios and additives is a key technology for achieving high-grade floor quality (such as super-flat floors and wear-resistant floors). The following are the experiences and guidelines for adjusting the operating parameters of the power trowel machine according to the characteristics of different concretes: Understanding the interaction: The "temperament" of concrete (setting speed, hardness, bleeding) determines how the power trowel should "treat" it. Observation is more important than presetting: Parameters have no fixed values, and the only criterion is the state of the concrete surface. An excellent operator is one who "watches the work" during construction rather than mechanically timing. Step by step: From low speed to high speed, from large angles to small angles, gradually apply pressure and improve precision. Characteristics: High cement content, dense slurry, fast setting speed, high early strength, and low bleeding. Operational challenge: The operation window period is short, making it easy to miss the best polishing opportunity. The surface is prone to rapid hardening and it is difficult to extract slurry. Adjustment strategy Rotational speed The first pass (disc slurry lifting) : It should be done a little earlier and at a medium to low speed (about 60-80 RPM). Because the slurry is thick, sufficient force is needed to bring it to the surface, but if the rotational speed is too high, it will curl the slurry and roughen the surface. Second and third coats (power trowel polishing) : After the surface is slightly dry, immediately change the power trowel and use medium-high speed (about 90-120 RPM). High speed helps to make the surface very dense and bright. Once you notice a significant increase in machine resistance and the surface starts to feel "rough", it indicates that the final setting is approaching and you need to stop immediately. Blade Angle The first power trowel: The Angle can be slightly level (about 3-5°), mainly for leveling and avoiding too deep a cut. Subsequent power trowel: As the surface hardness increases, gradually raise the blade Angle (about 5-10°), and use the sharp edge of the blade to perform a "cutting" type of polishing to achieve an extremely high gloss. Core experience: "Racing against time". Personnel and equipment must be ready. Once the concrete meets the conditions for machine operation, continuous work should be carried out immediately until completion. Characteristics: The initial and final setting times are significantly prolonged. The surface remains in a "soft" state for a long time, but the interior is slowly setting. Operational challenges: Prone to premature operation, which can damage the surface structure; The long waiting time affects the construction efficiency. It may be accompanied by bleeding. Adjustment strategy Rotational speed First round (disc) : You must wait! Until the depth of the foot depression is less than 5mm. Use a low speed (about 50-70 RPM) to lift the slurry smoothly, as the surface support force is still insufficient. Subsequent polishing: The interval between each application is quite long, requiring great patience. Always use medium and low speeds to avoid surface "wavy" or "curled skin" caused by excessive speed. Blade Angle Throughout the entire process, always maintain a relatively small Angle (approximately 0-5°). Because concrete is soft, if the Angle is too large, it will overly erode the surface and form grooves. Core experience: "Patience". Never be in a hurry to use the computer. If there is bleeding on the surface, it should be scraped off with water first or wait for it to evaporate. The operation mainly involves "gentle kneading". Characteristics: Fast setting speed and rapid strength growth. Operational challenge: The operational window period is extremely short, almost an "accelerated version" of high-grade concrete, making it easier to miss the opportunity. Adjustment strategy Rotational speed All rounds: The pace should be fast. The disc and the first power trowel operation can be combined or carried out quickly and continuously. The rotational speed can be medium to high (80-100 RPM) to complete compaction and smoothness within a limited time. Blade Angle The blade Angle can be raised relatively quickly. When applying the second coat of gloss, a relatively large Angle (about 7-10°) can be adopted to seize the final opportunity for pressing. Core experience: "Prediction and connection". The operator must constantly observe the surface changes. After the disc operation, the power trowel operation should be seamlessly connected. Machines can't stop. When people rest, the machines don't. Characteristics: The early strength is relatively low, and the setting speed is slightly slower, but the later strength is high, and the surface is easier to smooth. Operational challenges: Low surface strength in the early stage and prone to damage; However, the slurry has good lubricity and is prone to excessive polishing, which can lead to bleeding. Adjustment strategy Rotational speed First pass (disc) : The waiting time is similar to or slightly longer than that of ordinary concrete. Lift the slurry smoothly at medium speed (about 70-90 RPM). Subsequent polishing: Due to its excellent lubricity and wear resistance, it can be polished multiple times at medium speed, making it easy   Concrete type Disk stage rotational speed The rotational speed of the power trowel stage Suggested blade Angle Core operational philosophy High grade/low water-binder ratio Medium and low speed (60-80 Medium and high speeds (90-120) From flat (3-5°) to steep (5-10°) Race against time and increase pressure step by step Add retarder Low speed (50-70 Medium and low speed (70-90) Always maintain a small Angle (0-5°) Wait patiently and operate gently Adulterated with early strength agents Medium and high speeds (80-100) Medium and high speeds (90-110 Quickly increase the Angle (7-10°) Predictive connection, quick and decisive High-admixture Medium speed (70-90) Medium speed (80-100) Medium Angle (5-8° Gentle multiple times, taking advantage of the characteristics Note: The unit of rotational speed is RPM (revolutions per minute), which is an empirical reference value. The specific speed should be subject to the machine model and on-site conditions. The "Better late than early" rule: No matter what the ratio is, it is better to apply the gloss on the machine a little later than a little earlier. The machine may be strenuous at night, but in the morning it will completely damage the surface structure and cannot be remedied. Footprint Method for timing: Disc operation: Footprint depth is approximately 3 to 5 mm. The first power trowel: The depth of the footprint is approximately 1-2 mm. Final polished: The footprints are extremely shallow or non-existent, and the foot feel is hard. Listen to its sound, observe its trace Too high rotational speed/too early timing: The machine makes a dull sound, has high resistance, and there are "slurry" or "scratches" marks on the back of the blade. Too low speed/too late timing: The machine jumps severely, the blade "floats" on the surface and cannot be eaten, leaving white scratches without luster. The Angle and rotational speed are optimally matched: the machine operates smoothly, with uniform sound, and the blade leaves a uniform, bright, and traceless surface after passing through. Mastering these adjustment experiences requires a great deal of practice and careful observation. The best approach is to consciously associate the concrete mix ratio, weather conditions, the adopted operation parameters and the final effect with each construction, constantly accumulate and correct one's own "experience database", and thus become an expert in concrete plastering capable of handling any "temper".   Note: The parameters provided in this document are for reference only and are not mandatory.
