Use floor grinding machine need to pay attention to these points

There are often customers ask questions, how to use the grinding machine, if it is broken, what to do? Grinding machine as a vital machine in the floor construction, whether it is epoxy base or seal curing agent floor need grinding machine grinding construction. So, floor grinding machine in the use of what we should pay attention to the problem? Before construction, we must have a good understanding. 1. Choose the right machine type When the ground for rough grinding, we should choose a large floor grinding machine for grinding, large machine grinding can not only improve work efficiency, but also ensure the flatness and beauty of the ground after construction. On the contrary, if it is a small area such as corners, templates, stairs, etc., choose a small grinding machine or manual grinding. 2. Grasp the polishing time well Ground in the rough grinding, to test grinding, this is because the ground is made of a variety of materials mixed. If the grinding is too early, the sand particles may fly out during the grinding process, thus forming problems such as needle holes. If the grinding is too long, there will be gaps between the materials, resulting in reduced ground strength. Therefore, we use floor grinding machine rough ground to choose the appropriate grinding time. 3. Check whether the grinding machine is running normally In the process of using the grinding machine, you may encounter a sudden stop of operation. This requires checking whether the power supply and the machine wire interface are normal. If the power is normal, you need to check whether the motor is in good condition and whether it is burned out. If these are normal circumstances, or can not run, it is necessary to check whether the wire is too long or the power cord core is too thin, resulting in insufficient voltage can not drive the machine to run. 4. Regulating grinding disc leveling The uneven grinding disc will cause the grinding machine to shake violently during operation, and the ground will be uneven. The solution is to adjust the grinding disc fixing screw locking to change the height of the grinding disc. Make the distance from any three points of each grinding disc to the bottom of the gearbox consistent, and adjust the four grinding discs to be stationary or tend to be in the same plane during operation. The above points are only in the floor construction, the construction personnel can judge to solve the problem, if the party itself can not solve, you need to contact the professional maintenance personnel to solve.

After the reform and opening up, infrastructure construction has been increasing year by year. In order to improve the efficiency of engineering construction, China has successively introduced a number of foreign vibratory compaction machinery products and technologies, among which the most representative ones are Dynapac CC series and BMW G BW series road rollers. After more than ten years, the domestic compaction machinery industry is in the stage of transformation, absorption and serialization. By the end of the 1990 s, domestic roller manufacturing enterprises have begun to take shape and have the ability of independent research and development. Entering the 21st century, the development of the compaction machinery market is roughly divided into three stages.

In recent years, with the implementation of the Belt and Road strategy launched by the country, the number of construction machinery exports to countries along the route has begun to increase. In 2018, my country's export volume of various road rollers increased to 3202 units. However, after 2018, the export volume of road rollers has declined, which is mainly due to the continuous appreciation of the real exchange rate of RMB, weak external demand, industrial upgrading and other factors. From January to October 2021, China's road roller exports were 4502 units, up 1763 units or 64.4 percent year-on-year. The increase in exports was mainly due to the impact of the global epidemic.

Roller Technology 1. Intelligent complete set In recent years, Internet information technology has made rapid development, which has also brought revolutionary changes to the field of compaction machinery. The collection and processing of compaction parameter information in the process of cluster construction has become the focus of the next stage of development. Domestic enterprises have invested huge financial and material resources in informatization to build a cloud platform and improve the level of informatization services. However, owners often use multiple brands of compaction equipment in the large-scale construction process, and there is a lack of compatibility between intelligent platforms; intelligent equipment Mainly based on the owner's transformation of existing equipment, it is difficult to form a large-scale application. The solution to the problem is complete procurement and construction. The compatibility and scalability of the respective intelligent platforms of the enterprises will control the sales and promotion of intelligent services of compaction machinery manufacturing enterprises. 2, environmental protection and energy saving requirements gradually improve According to the requirements of the national standard for diesel engines for non-road mobile machinery, starting from April 1, 2016, the manufacture, import and sale of non-road mobile machinery equipped with diesel engines in the second stage will be stopped. All non-road mobile machinery manufactured, imported and sold shall be equipped with diesel engines that meet the requirements of the third stage of this standard, and domestic compaction machinery shall be fully upgraded to country III emissions. In addition, due to the large proportion of fuel costs in construction, the choice of lower energy consumption compaction machinery has become the main consideration of the construction side. Manufacturing enterprises have also launched economic model or energy-saving model products to meet the increasingly stringent energy-saving requirements. 3, reliability requirements to improve Reliability has always been a hurdle made in China. At present, the gap between domestic high-end products and foreign products is in the control of reliability. High early feedback rate and low mean time to failure have become the biggest problem in this field. Under the premise of the construction machinery market downturn, domestic users are more inclined to foreign brand products with higher reliability, and the share of domestic high-end compaction machinery is gradually being eroded. In this case, increasing research and investment in reliability has become the choice of enterprises. 4. Improved operation comfort With the continuous improvement of people's material living standards and the use of foreign products, the operator's requirements for the operating environment have gradually increased, and the bidding requirements for low noise, small operating force, adjustable operating devices, panoramic cabs, air conditioning and other configurations have risen rapidly. In addition, foreign users of compaction machinery are also constantly making demands on the comfort of manipulation, which will surely become a breakthrough in the development of the enterprise market. 5. Improvement of working condition adaptability The use of compaction machinery varies from country to country and from region to region. For example, foreign light machinery is mainly used for small engineering light load field operations, but domestic users need to be able to meet the grass-roots and asphalt surface construction. Foreign brand models are not suitable in China, so we must develop models that meet the needs of localization. For example, the demand for rock crushing in dam construction, the demand for large fill in the construction of new urban areas in mountainous areas, the demand for adaptability of plateaus and plains, the demand for temperate and tropical construction, and the demand for humid islands and land construction pose more severe challenges to compaction machinery. The adaptability of different environments and different operating devices has become the direction of future research.

What is a towed vibratory roller? What is a towed impact roller?

Trilateral towed impact roller Both towed impact roller and towed vibratory roller belong to towed roller. In short, they are engineering compaction machinery that does not have walking function and needs to work under the drive of traction machinery. Quadrilateral drag impact roller Among them, the impact roller of the towed impact roller is non-circular polygonal structure, according to the different shape structure, divided into three-sided impact roller, four-sided single-wheel impact roller and five-sided two-wheel impact roller. Self-propelled pentagonal impact roller The working principle of the towed impact roller is the same as that of the self-propelled impact roller. The impact force of the three-sided impact roller is relatively large, which focuses on the impact compaction of the roadbed. The force of the four-sided impact roller is moderate. Both of them can be used for compaction of the roadbed and pavement crushing. Moreover, the four-sided impact compactor is designed with a single wheel, and the pavement is relatively narrow, the impact force of the pentagonal impact compaction wheel is relatively weak compared with the three-sided impact compaction wheel, which is mostly used for road crushing and impact compaction of silty soil and sandy soil. self-propelled vibratory roller The working principle of towed vibratory roller is the same as that of self-propelled vibratory roller. It also relies on self-weight and exciting force to force the compacted material to do vertical forced vibration, which sharply reduces the internal friction between soil particles and achieves the purpose of compacting soil. The size of the exciting force can be adjusted as needed. towed vibratory roller Towed vibratory rollers are rollers with single steel wheel structure. According to different weight and different output power, it is divided into light towed vibratory roller and heavy towed vibratory roller. Generally speaking, if the weight of the equipment is less than 10 tons, it can be defined as a light towed roller. Due to different requirements of construction specifications, it is widely used abroad. light towed vibratory roller Equipment with a weight of more than 14 tons is called heavy towed roller, which is widely used in China. Heavy towed vibratory roller is an indispensable compaction machinery in the foundation construction of highways, railways, dams, airports and other large-scale projects, especially for large-scale filling construction, when the compaction degree is required to be more than 95%, it shows the necessity and efficiency of this kind of machinery. Heavy towed vibratory roller Light towed vibratory roller and heavy towed vibratory roller are used in different ranges, and different towed rolling wheel quality or exciting force can be selected according to different compaction thickness and materials. In addition, due to the small weight of the vibrating wheel, the power output of the light towed vibratory roller is mostly borrowed from the power output of the tractor, while the heavy towed vibratory roller is mostly equipped with high-power power output.
