Large area floor laser leveling machine leveling construction method

    The routine inspection, fault early warning and maintenance points of the hydraulic system of the concrete laser leveling are a crucial topic, as the health condition of the hydraulic system directly determines the construction efficiency, leveling accuracy and equipment service life of the leveling. The following is a detailed and systematic guide. Objective: To prevent problems before they occur and promptly identify potential issues through daily observation. Oil level check: When the equipment is parked on a level ground and the hydraulic system is not started (or the cylinder has been retracted), check the oil level gauge in the hydraulic oil tank. The oil level should be between the marked upper and lower scale lines. Low oil level can cause the pump to run dry, the system to overheat and get damaged. If the oil level is too high, it may cause excessive pressure or oil leakage from the breather valve when the oil temperature rises. Leak inspection: Carefully inspect the entire hydraulic system, including: Pipe joints: Check for oil stains or dripping oil. Cylinder piston rod: Check for any scratches, bends or continuous leakage. Hydraulic pump, valve block, motor: Check if there is any leakage at the mating surface. Fuel tank surface: Whether it is clean and free of oil stains. Oil color: Observe the color of the hydraulic oil through the oil level gauge. New hydraulic oil is usually transparent amber in color. If it is found to be turbid and opaque (possibly water ingress), darker and blackened in color (possibly oxidation and deterioration), or milky white (definitely water ingress and emulsification), further treatment is required. Abnormal noise: Start the engine and operate various hydraulic actions (lifting, walking, vibration, etc.). Listen carefully for any sharp "click-click" sounds (cavitation sounds) or continuous dull abnormal noises from the hydraulic pump (possibly due to internal wear of the pump or motor). Vibration and Pulse: Touch the hydraulic pipeline with your hand to feel if there is any abnormally intense vibration or pulse sensation. This may be a sign of oil circuit blockage or pump/motor failure. Temperature: After working for a period of time, touch the outer shell of the hydraulic oil tank with your hand. If it feels hot to the touch (the temperature may exceed 60-70°C), it indicates that the system is overheated and needs to be shut down for inspection. Slow movement: Test the movement of all cylinders and motors to see if there is any slowdown in speed, weakness or jamming. Pressure maintenance: For the lifting cylinder, observe whether there is obvious "sinking" (i.e., internal leakage) after it is lifted. Objective: Identify early symptoms of faults to prevent minor issues from evolving into major ones. Warning signal Analysis of Possible causes Potential risk Slow and weak movements 1. Insufficient hydraulic oil or incorrect viscosity of the oil. The leveling accuracy has declined, making it impossible to work normally and resulting in low efficiency. 2. The main pump is worn out and internal leakage occurs, resulting in insufficient pressure/flow. 3. The set pressure of the relief valve (safety valve) is too low or the valve core is stuck. 4. Severe internal leakage of the actuator (cylinder/motor). Abnormal noise from the system (pump 1. The oil suction pipeline is clogged or the filter element is dirty. The hydraulic pump will be severely damaged in the short term and must be shut down immediately. 2. When the oil level is too low, the pump sucks air, causing cavitation. 3. Air mixed into the hydraulic oil (due to poor sealing of the pipelines). 4. The bearings or internal components of the pump itself are damaged. The system is severely overheating. 1. The hydraulic oil cooler is clogged (air-cooled or water-cooled). Accelerate the oxidation and deterioration of the oil, the aging of seals, and the wear of all hydraulic components. 2. The relief valve is frequently opened or the set pressure is too high. 3. Improper viscosity or deterioration of the hydraulic oil. 4. Severe leakage inside the pump or valve causes energy loss, which is converted into heat energy. The cylinder is crawling and shaking 1. There is air in the cylinder. It affects the stability of the leveling operation, causing waves to appear on the ground. 2. The wear of the piston seal in the oil cylinder leads to unstable pressure. 3. Oil contamination leads to the valve core of the control valve getting stuck and discontinuous movement. The hydraulic oil deteriorates rapidly 1. The oil temperature has been too high for a long time, leading to oxidation. Cause abrasive wear and corrosion of all hydraulic components. 2. Water enters the oil (such as leakage from the water cooler). 3. Contaminants (dust, metal shavings) invade the system. External leakage Aging of seals, damage to oil seals, loose joints, and wear and rupture of pipelines. Waste of oil, environmental pollution, insufficient system pressure, and even fire. Objective: Establish a scientific maintenance system to maximize the system's lifespan. Regularly change the hydraulic oil and filter elements: Strictly follow the oil change cycle specified by the equipment manufacturer (usually 500-1000 working hours). In harsh and dusty environments, the cycle should be shortened. When changing the oil, all hydraulic filter elements (suction oil filter, return oil filter, pressure oil filter) must be replaced simultaneously. Refueling must be filtered: When adding or replacing new oil, it is essential to use a dedicated fuel pump and filtering device. It is strictly forbidden to directly pour the oil drum into the fuel tank. Keep the fuel tank clean: Clean the area around the fuel tank cap before refueling to prevent debris from falling in. Regularly clean the magnetic plugs inside the fuel tank. Regularly clean the fins of the hydraulic oil radiator to ensure good ventilation and no blockage from concrete, dust, etc. Avoid the equipment operating under extremely high load for a long time. If the ambient temperature is high, an auxiliary cooler can be considered for installation. Ensure the sealing of all suction pipelines to prevent the pump from being sucked empty. Regularly check whether the fuel tank breathing valve is unobstructed. After the machine stops, regularly check the water outlet at the bottom of the fuel tank for any water. For key equipment, samples can be taken regularly and sent to professional laboratories for testing. The analysis report can inform you of the contamination degree of the oil, the composition of worn metals, water content and physical and chemical indicators, thereby accurately predicting faults, achieving oil replacement based on quality and saving costs. Avoid operating the hydraulic cylinder piston rod only when it reaches the end of its stroke. Instead, release the operating rod before approaching the end to take advantage of inertia to reach the position and reduce the impact. When starting up in winter, it should first run at low speed without load for a period of time to allow the oil temperature to rise and the viscosity to decrease before commencing operations.
