What are the applicable scopes of concrete laser leveling machines?

In the process of using the laser leveling machine, pay attention to the harm caused by unfavorable factors to the leveling machine, because the working environment of the leveling machine has always been relatively harsh, so when the leveling machine is working, it will inevitably be damaged by the surrounding unfavorable factors, and it will also lead to a decline in the working efficiency of the laser leveling machine. Later, the failure will inevitably become more and more serious, so everyone should be careful when using it. 1. Avoid impurities: For laser leveling machines that work in harsh environments and complex conditions, first of all, use high-quality and matching parts, lubricating oil, and grease to block the source of harmful impurities; secondly, do a good job of mechanical protection at the work site to ensure that the corresponding mechanisms can work normally and prevent various impurities from entering the interior of the machine. For the faulty laser leveling machine, try to go to the regular repair place for repair. When on-site repairs, protective measures must also be taken to prevent the parts replaced during on-site repairs from being polluted by impurities such as dust before entering the machine. 2. Applicable temperature: During the use of the laser leveling machine, firstly, it is necessary to prevent overload operation at low temperature, ensure the normal operation in the low-speed preheating stage, and make the machine reach the specified temperature before driving or working. Do not ignore its important role because there is no problem at that time; secondly, prevent the laser leveling machine from operating at high temperature. During the operation of the machine, the values on various thermometers should be checked frequently. For those who can't find the reason for a while, the laser leveling machine must still work with the disease without treatment. In normal work, pay attention to check the working condition of the cooling system. For water-cooled machines, it is necessary to check and add cooling water before work every day; for air-cooled machines, the dust on the air-cooling system should also be cleaned regularly to ensure the smooth flow of cooling air ducts. 3. Anti-corrosion: In the use of laser leveling machines, management and operators should take effective measures according to the local weather conditions and air pollution conditions at that time to reduce the impact of chemical corrosion on laser leveling machines. The focus is to prevent the intrusion of rainwater and chemical components in the air to the machinery.

– When the trowel speed is moderate, it can effectively flatten the raised parts of the concrete surface and fill the sunken parts. For example, in general indoor floor construction, if the trowel speed is set in a suitable range, such as 70-100 rpm, the blade on the trowel can initially level the newly poured concrete surface as the trowel moves forward. Because at this speed, the pressure and flattening effect of the blade on the concrete are relatively uniform, and it will not be over-cut due to too fast a speed, nor will it be unable to effectively deal with the unevenness of the surface due to too slow a speed. – When the trowel speed is too high, the cutting force of the trowel blade on the concrete surface is too large. This may cause over-cutting of the concrete surface, destroy the original structure of the concrete, and cause fine cracks or pits on the surface. Especially for concrete whose strength has not yet fully developed, too high a speed may excessively disturb the cement slurry layer on the surface, affecting the final quality of the concrete. – On the contrary, if the trowel speed is too low, the trowel blade will not have enough force on the concrete surface. This will make it impossible to effectively deal with the uneven parts of the concrete surface. For example, on the concrete surface with large stone protrusions or template splicing marks, the trowel at a low speed may not be able to remove these defects, resulting in the ground flatness not meeting the requirements. – Appropriate trowel speed helps to improve the compaction of the concrete surface. When the trowel rotates at a certain speed, the weight of the trowel and the rotation of the blade work together to exert pressure on the concrete surface, so that the particles in the concrete are arranged more closely. For example, in concrete construction with high bearing capacity requirements such as industrial plant floors, the trowel speed is controlled at about 80-120 rpm, which can make the concrete surface better compacted during the troweling process, thereby improving the bearing capacity and wear resistance of the ground. – When the speed is too high, although the surface looks smoother, it may actually make the mortar layer on the concrete surface too loose. Because too high a rotation speed will cause the water in the mortar layer to evaporate too quickly, and excessive rotation will destroy the bonding force between the mortar particles, resulting in insufficient surface compaction, which is prone to quality problems such as sanding and peeling during later use. – If the speed of the trowel is too low, it will not generate enough pressure to compact the concrete surface. This will make the porosity of the concrete surface larger and reduce the compactness of the concrete. Such a concrete surface is easily damaged when there are heavy objects rolling or frequent friction. – A higher trowel speed can make the concrete surface have better gloss. When the speed reaches a certain level, such as 100-150 rpm, the trowel blade can further smooth the mortar layer on the concrete surface during rapid rotation, making the surface more delicate and producing gloss. In some places with high requirements for appearance, such as shopping mall floors and exhibition hall floors, by appropriately increasing the trowel speed, a smooth mirror effect can be created. – However, if the speed is too high, it may cause wavy textures on the concrete surface, affecting the uniformity of gloss. This is because too high a speed will cause the trowel to vibrate during the rotation process, and this vibration is transmitted to the concrete surface, affecting the surface flatness and destroying the uniformity of the gloss. – When the speed is too low, the surface roughness of the concrete is greater and the glossiness is poor. Because the trowel rotating at a low speed cannot fully smooth the microscopic unevenness of the concrete surface, it cannot form a smooth surface, and can only obtain a relatively rough matte effect.

As construction units continue to increase their requirements for the color, appearance, and flatness of large-area concrete floors, the problems of traditional construction processes in terms of construction progress and quality are becoming increasingly prominent. The use of concrete laser leveling machines for one-time floor forming construction has far greater advantages in terms of process, technology, and cost than the former. In order to effectively improve the operating efficiency of concrete laser leveling machines, this article briefly summarizes some methods and techniques from the perspective of purchase and maintenance, hoping to help everyone's future use. ✪ How to judge whether the quality of a laser leveling machine is good? 1. Look at the effect. High-quality laser leveling machines have more stable effects. 2. Look at the speed. High-quality laser leveling machines have faster leveling speeds. 3. Look at the accuracy. High-quality concrete laser leveling machines have higher leveling accuracy. 4. Look at the model. The selection of a suitable laser leveling machine is mainly based on the construction site and area. 5. Look at the manufacturer. The technical strength of the manufacturer of concrete laser leveling machines directly affects the quality of the equipment. 6. Look at safety. When selecting a laser leveling machine, the braking performance and operational safety of the concrete laser leveling machine must also be fully considered. ✪✪How to judge whether the laser leveling machine is a new equipment? 1. Check whether there is noise during operation. Hold the inner sleeve of the bearing body of the concrete laser leveling machine with your left hand, and turn the outer sleeve with your right hand to make it rotate, and listen to whether there is noise during the operation of the bearing. Since most counterfeit products are produced under backward conditions and are completely operated in a manual workshop, it is inevitable that impurities such as dust and sand will be mixed into the bearing body during the production process, so there will be noise or unsmooth operation when the bearing rotates. 2. Check whether there is oil stain on the surface. This should be paid special attention to when purchasing. Since the current anti-rust technology is still a little behind that of foreign manufacturers, many manufacturers are prone to leave thick oil stains when anti-rusting concrete laser leveling machines, and there will always be a sticky touch when directly touching them with your hands. 3. Check whether the printing on the parts is clear. The bearing products of each laser leveling machine are usually printed with their words, numbers, etc. The counterfeit fonts are not only blurred, but also float on the surface due to the rough printing technology. Some can even be easily wiped off by hand or have serious manual traces. 4. Check whether the outer packaging is clear. Generally speaking, the concrete laser leveling machines produced by regular manufacturers have their own dedicated designers to design the outer packaging, so the whole machine packaging should be very clear from lines to color blocks. ✪✪✪How to judge whether the laser leveling machine needs overhaul? Due to the great differences in the operating conditions and maintenance levels of different concrete laser leveling machines, it is difficult to determine the reasonable overhaul time based on the service life and working time alone. According to many practical results, we recommend that the laser leveling machine generally needs an overhaul after working for 4000-6000 hours. Machinery that needs overhaul usually has the following symptoms: 1. The pipelines and sealing components of the hydraulic system are aging and the oil leakage is serious. 2. The circuits of the electronic control system are aging, the control accuracy is reduced, and the failure rate is high. 3. The engine power is significantly reduced, and symptoms such as blowby, burning oil, and difficulty in starting appear. 4. The concrete laser leveling machine has been working for about 5000 hours, but its transfer case, transmission, and reducer have never been repaired; 5. The hydraulic power of the leveling machine has decreased, which is generally manifested as insufficient walking power or material distribution power. Specifically, it is basically normal for small load operations, barely able to operate with medium loads, but unable to operate with large loads. Warm reminder: Choosing the right model and ensuring the performance of the machine are important prerequisites for the safe use of the concrete laser leveling machine, and learning maintenance skills is a necessary requirement to maintain the good operation of the laser leveling machine and extend the service life of the machine, so both aspects need to be given enough attention.
