Concrete laser leveling summer maintenance 1.The hot weather construction to prevent engine overheating, in general, the temperature of the engine not more than 95 °, if the temperature is too high, you should select a shaded area to cool down, down at the same time can have the fuselage cover ventilation cooling. 2.Before entering the summer, should thoroughly remove the combustion chamber, valve top and the carbon of other parts in order to maintain good heat dissipation and normal compression ratio, in case of engine deflagration. 3.Often clean the hydraulic oil radiator, in order to prevent poor heat dissipation. 4.In the summer construction, high temperature, need to check the tire pressure and tire temperature, if the tire temperature is too high should be promptly shut down and placed in a cool place to cool down, disable the wrong way to vent or pour cold water to cool down. 5.The electrical system should pay attention to waterproof, do not open the box cover, do not use water to wash the electrical protection box, do not use corrosive liquid cleaning machine! 6.Check the temperature of hydraulic oil and hydraulic transmission oil.The temperature is too high to rest, not more than high temperature operation. 7.To pay attention to the daily maintenance of concrete machinery and equipment.The operator should regularly carry out comprehensive maintenance of the machinery, due to the rise of temperature, summer construction must be timely replacement of the engine air filter, oil filter and oil, and check the performance of the fan, water tank, generator is reliable, necessary maintenance, maintenance or replacement;At the same time, the concrete solidification speed is fast in summer, so the concrete impurities of the fuselage should be cleaned in time to ensure the cleanliness of the fuselage.

Daily maintenance After each work, clean the concrete and dust on the machine timely. It is recommended to replace the air filter once every 100 hours. In many dust areas, the frequency of cleaning and replacement should be increased. Replace the oil after the first 20 hours of operation, and then replace it every 100 hours. When disposing of the waste oil, it is recommended to put it in a sealable container and give it to the recycling center to protect the environment and soil Grease the grease nipple above the cross for daily maintenance

Cold planer is the key machine for pavement milling. Recycling of the road surface is one of the main reasons for milling a road surface. Milling is widely used for pavement recycling today, where the pavement is removed and ground up to be used as the aggregate in new pavement. For asphalt surfaces the product of milling is reclaimed asphalt pavement (RAP), which can be recycled in the asphalt hot mix asphalt (pavement) by combining with new aggregate and asphalt cement (binder) or a recycling agent. This reduces the impact that resurfacing has on the environment. Milling can also remove distresses from the surface, providing a better driving experience and/or longer roadway life. Some of the issues that milling can remove include: Raveling: aggregate becoming separated from the binder and loose on the road Bleeding: the binder (asphalt) coming up to the surface of the road Rutting: formation of low spots in pavement along the direction of travel usually in the wheel path Shoving: a washboard like effect transverse to the direction of travel Ride quality: uneven road surface such as swells, bumps, sags, or depressions Damage: resulting from accidents and/or fires It can also be used to control or change the height of part or all of the road. This can be done to control heights and clearances of other road structures such as: curb reveals, manhole and catch basin heights, shoulder and guardrail heights, and overhead clearances. It can also be done to change the slope or camber of the road or for grade adjustments which can help with drainage.

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.

For now, more and more floor constructor using concrete laser leveling to do the work, because concrete laser leveling contact materials are not the same, leading to maintenance methods of the machine is not the same, so we must pay attention to the details in use, after the completion of the work to do well on the machine maintenance work, here we give details about the concrete leveling machine maintenance knowledge. 1. Avoid impurities. For concrete laser leveling working in harsh environment and complex condition places, the first thing is to use high quality, supporting components and lubricating oil and grease, the source block harmful impurities; Second, we should do a good job in the mechanical protection of the work site, to ensure that the corresponding institutions can work normally, and prevent various impurities into the machinery. When mechanical failure occurs, try to go to the regular repair plant to repair it. When repairing in the construction site, the protective measures should be done to prevent the change of the parts from the site to be contaminated by the dust and other impurities before entering the machine. 2. Applicable temperature. During the use of concrete laser leveling, we must prevent overload operation at low temperature, ensure normal operation at low speed preheating stage, and make the machine run or work after the specified temperature. Do not neglect its important role because there is no problem at that time. To prevent machinery from running at high temperature, we should check the values on various thermometers regularly during mechanical operation, find the problem and stopped immediately, check and find out the trouble and eliminate it in time. 3. Corrosion protection. During operation, management and operation personnel should take effective measures according to the local weather and air pollution at that time, so as to reduce the influence of chemical corrosion on machinery. The key is to prevent chemical invasion of rainwater and air from invasion to machinery. 4. Timely maintenance. There will be a variety of failures in the use of the concrete leveling machine. In these failures, the effects of some failures on mechanical equipment may be very small, some are more serious, and even cause casualties. We should try to ensure that the mechanical load is uniformly increased and reduced, so that the machinery can be in a relatively gentle load change. Specifically, it is to increase and decrease the throttle more evenly, to avoid the engine and the working device will suddenly fluctuate dramatically. If you have any further question, just contact us, I’m pretty sure that your any questions will get a proper respond. VANSE focus on concrete laser leveling.

You can do it yourself with some easy way to handle it. Here to teach you a simple and effective way: found a new small scars, the toothpaste gently wipe the circle painted on the scratch. This can generally reduce the mark imprint, you can simply play a role in isolation, to prevent rust, no problem in the short term. The above is Xiangjiang Xiao Bian for your finishing on the surface of the maintenance of the road, you learn it?

Concrete cutting process With the accelerated pace of urbanization, urban construction with each passing day. In the big city, the ground has been unable to meet the traffic requirements, urban traffic up to the elevated, light rail, down to the subway. Some elevated posts now seem to be factors that constrain urban development. It is inevitable that some of the elevated structures are to be demolished, and that part of it is not affected and reused, which has become a problem before us. In the traditional demolition of this construction can not do anything, advanced reinforced concrete cutting method is safe, efficient and environmentally friendly features. Reinforced concrete cutting technology mainly disc cutting method and diamond wire cutting method. Diamond wire cutting method has faster speed, greater flexibility and lower construction noise. Especially in the construction renovation project has been more and more applications. Disc cutting method to break the traditional wind pick chisel after the gas cutting or directional blasting construction methods, with diamond particles with cutting disc cutting, construction incision neatly, straight, without post-processing, free from construction sites, environmental protection , Duration, safety reasons and other conditions, is widely used in various types of large-scale building structural transformation and cutting construction. The steel wire cutting method is composed of high power hydraulic press, transmission locating pulley and steel wire with diamond sawtooth. The hydraulic motor drives the steel wire around the cutting object to rotate at high speed through the drive pulley. It has the advantages of fast construction and noise Low, no vibration, no dust and other advantages of waste gas pollution, and incision straight and smooth, no need to do after the processing. The use of the technology, for some of the special requirements of the construction of the project, such as tight schedule, high environmental requirements, as well as some large concrete structure demolition, cutting works, these problems can be solved.
