High quality cement machinery concrete laser leveling

    The construction quality of a power trowel (also known as a finishing machine) is 70% about leveling and 30% about operation. The flatness of the chassis and the blade is the key to determining whether the concrete surface ultimately achieves a mirror-like smoothness, without ripples or flaws. The following are detailed technical tips for leveling the base of a power trowel and calibrating the consistency of the blade height, combining the experience of experienced masters with scientific methods. One benchmark: Take the chassis as the sole benchmark. All blade adjustments must be based on a already leveled chassis. Three unifications: uniform blade height, uniform inclination Angle, and uniform wear degree. The chassis serves as the installation platform for the blade. If the chassis itself is uneven, the consistency of the blade is out of the question. First choice: A large and flat platform (such as a calibrated granite platform, a thick tempered glass tabletop or a new thick steel plate). Second choice: On a very flat ground, use a known uniform thickness pad (such as a feeler gauge). Essential items: feeler gauge, tape measure, marker pen. Cleaning and preparation Thoroughly clean the chassis and remove all cement slurry and hard lumps. Check the chassis for any obvious deformation caused by the collision. If there is severe deformation, it needs to be corrected or replaced first. Place the power trowel on the platform and ensure that the contact surface between the chassis and the platform is clean and free of debris. Preliminary "Four-point measurement Method" Consider the chassis as a clock face and measure the gap between the edge of the chassis and the surface of the platform at the four positions of 12 o 'clock, 3 o 'clock, 6 o 'clock and 9 o 'clock. Use a feeler gauge to measure and record the gap values at four points. Preliminary judgment: If the gap values at the four points differ by more than 1-2 millimeters, it indicates that the chassis is uneven and needs to be adjusted. The chassis of most power trowels is connected to the main unit through three or four adjustable pull rods. Identify the high and low points: Based on the measurement data, determine which corner has the smallest clearance (the highest point of the chassis) and which has the largest clearance (the lowest point of the chassis). To raise a certain Angle, loosen (counterclockwise) the lock nut of the pull rod corresponding to that Angle, then shorten the length of the pull rod (turn the pull rod body clockwise), and finally tighten the lock nut. To lower a certain Angle, loosen the lock nut, then extend the length of the pull rod (turn it counterclockwise), and finally lock it. The mnemonic: "High pines are short, low pines are long." (For the angles that need to be adjusted After each adjustment, gently rotate the chassis (to prevent scratching the platform) and conduct the four-point measurement again. Repeat steps 3 and 4 until the difference in gap values among the four points is controlled within 1 millimeter. At this point, it can be considered that the chassis has been leveled. The calibration of the blade can only be carried out on the basis of ensuring that the chassis is absolutely flat. A ruler (preferably a high-precision steel ruler) or a dedicated blade height gauge. Tape measure, marker pen, wrench. Installation and cleaning Install a set of blades of consistent newness and oldness onto the blade seat. It is strictly prohibited to mix new and old blades! Make sure that all the blade fixing bolts and blade seats are clean, the threads are undamaged and can be tightened in place. Place the power trowel with the chassis adjusted on a flat ground. Place a fixed reference point (such as a thin gasket or directly using the joints of floor tiles) on the ground beneath the chassis and within the rotation trajectory of the blade. Stand a ruler vertically beside the reference point and measure the distance from one of the knife tips to the ground, recording it as the reference height H. It is extremely important: Manually and slowly rotate the base of the trotter so that the same position of the next blade (for example, the outermost end of both blades) rotates directly above the reference point. Measure the distance from the tip of the knife to the ground again with a ruler. Compare it with the reference height H and record the difference. For example: Blade 1 is H, blade 2 is H-1.5mm, and Blade 3 is H+1.0mm. Measure all the blades in sequence. The height of the blade is adjusted by the regulating bolt on the blade seat to change its inclination Angle. Adjustment principle If the measured value of a certain blade is low, it needs to be raised. The method is: tighten the adjusting bolt below the blade seat, or loosen the adjusting bolt above to lift the leading edge of the blade (the side close to the rotation direction). If the measured value of a certain blade is too high, it needs to be reduced. The method is: Loosen the adjusting bolt below the blade seat or tighten the adjusting bolt above it to lower the leading edge of the blade. Mnemonic: "High tight, low loose, the leading edge as the standard." (For the leading edge of the blade that needs to be adjusted After adjusting each blade, it is necessary to rotate and measure once again, as adjusting one blade may slightly affect the height of adjacent blades. Repeat steps 3 and 4 until the difference between the measured height of all blades at the reference point and the reference height H is controlled within ±1 millimeter. Final inspection: Rotate the chassis quickly and listen to the sound with your ears. When the highly uniform blades are idling, the wind sound is a uniform "buzz". Inconsistent ones will have a periodic noise of "puff puff". The sequence is crucial: the chassis must be leveled first, and then the blades calibrated. Reversing the order is in vain. Tools are the guarantee: Having an absolutely flat calibration platform is half the battle. Data-driven operation: Trust feeler gauges and rulers, not rely on the naked eye. Each adjustment should be measured and recorded. Complete set replacement: The blades must be replaced as a complete set to maintain the same wear condition. Regular inspection: A quick inspection should be carried out before starting work every day and after replacing the blade. A full set of calibration should be carried out every 50 to 100 hours of operation or after a collision. Safety first: All operations must be carried out when the machine is completely powered off and the engine is turned off. Through the above strict and meticulous process, your power trowel machine will be in the best working condition, capable of easily creating a mirror-like smooth and high-quality concrete surface, effectively avoiding problems such as ripples, scratches and excessive cutting, thereby enhancing construction efficiency and professional image.   Note: The parameters provided in this document are for reference only and are not mandatory.

To sum up, when renting a concrete laser leveling, you need to pay attention to choosing the appropriate rental method, choosing a regular lessor, understanding the rental fees and deposits, checking the quality of the leveling, signing a rental contract, and paying attention to the precautions during use. Pay rent and maintenance fees on time and pay attention to the return of equipment. Only by carefully understanding and complying with the above precautions can we better use the concrete laser leveler and improve construction efficiency and quality.

  Many users often ignore a part when maintaining the laser leveler, that is, the fuel tank. During the process of the leveler leveling the ground, a lot of things will enter the fuel tank. If the fuel tank is not cleaned all the time, the more and more things accumulated in the fuel tank in the long run will inevitably have an adverse effect on the fuel tank. At this point, everyone should pay attention to the cleaning of the laser leveler fuel tank and learn to clean the fuel tank correctly. Correct method of cleaning the laser leveler fuel tank: The fuel tank cleaning is divided into two steps, internal and external. When cleaning the engine fuel system, use the engine non-disassembly cleaning agent, because the non-disassembly cleaning agent does not need to disassemble the fuel system. On the one hand, it can start to thoroughly clean the fuel system, and on the other hand, it is beneficial to protect the engine's fuel system. When cleaning the laser leveler, you can use a clean cloth to block the fuel pipe port, and then constantly change the position and direction of the plastic pipe to try to avoid rubbing the oil level sensor. After blowing and washing for 20 minutes, release the gasoline, and the impurities in the gasoline will flow out together. It should be noted that the fuel released from the fuel tank should be precipitated for 72 hours before use. When cleaning the outside of the fuel tank, it is necessary to check whether there are dents or oil leakage in the fuel tank, fuel pipes, joints, etc., and check whether the fixing screws of the fuel tank bracket are tightened; when cleaning the inside, open the fuel tank port, take out the filter barrel, suck out the oil, and then insert the cleaned plastic tube from the refueling port to the bottom of the fuel tank, and gently blow the gasoline at the bottom of the fuel tank to make it roll to achieve the cleaning effect. It is really necessary to clean the fuel tank of the laser leveler. As the laser leveler is used for a longer time, the precipitated impurities in the gasoline will accumulate more and more in the fuel tank. These impurities first settle at the bottom of the fuel tank. When there are too many sediments, they will enter the car engine with the fuel, causing serious wear and tear on the engine. As long as you clean the fuel tank once, car owners will find how necessary it is to clean the fuel tank regularly. During the cleaning process, not only particles and colloids, but even incredible things such as tin foil and plastic sheets will be washed out. Many things car owners don't know how they got into the fuel tank. If these wastes are not cleaned up in time, the impact on the engine of the laser leveler is imaginable. This is the end of the introduction to the method of cleaning the oil tank of the laser leveling machine. I believe that you have understood it very clearly after reading it.
