How to improve construction efficiency of large-area floor concrete laser leveling machine leveling construction method?

    When the hydraulic oil temperature of your power trowel is too high, you can check and implement the following solutions one by one in the order from simple to complex: These steps can be carried out quickly on the construction site, aiming to control the situation immediately. Immediately stop the polishing operation, lift the polishing disc and let the equipment idle for a few minutes without load. This can quickly relieve system pressure and reduce heat generation. This is one of the most immediate methods. The vast majority of power trowel use air-cooled coolers. Please immediately use compressed air or a low-pressure water gun to blow and wash from the inner side to the outer side of the cooler fins to thoroughly remove the dust, cement powder lumps and debris adhering to them, ensuring smooth ventilation. After the machine stops, check the oil level gauge of the hydraulic oil tank. Low oil level (insufficient oil volume) can cause the oil pump to suck air and have insufficient cooling circulation, resulting in high temperatures. If the oil level is too high, the foam inside the fuel tank will be difficult to dissipate, which will also affect heat dissipation. Make sure the oil level is between the upper and lower marks on the dipstick. Move the equipment to a cool and well-ventilated place and avoid continuous operation under direct sunlight or in an environment with extremely high temperatures. If the problem persists or recurs after emergency measures are taken, a more in-depth inspection is required. Oil type: Ensure the use of anti-wear hydraulic oil of the grade and viscosity level specified by the equipment manufacturer. Excessively high viscosity will increase flow resistance and generate heat, while excessively low viscosity will intensify internal leakage, leading to a decrease in pump efficiency and heat generation. Oil quality: If the hydraulic oil has turned black, has a burnt smell or produces a large amount of foam, it indicates that the oil has oxidized and deteriorated, and its lubricating and heat dissipation performance has sharply declined. The oil must be completely replaced with new oil, and the oil tank should be cleaned and the hydraulic oil filter element replaced at the same time. Cooling fan: Check whether the motor driving the cooling fan is working properly and whether the circuit is intact. If it is belt drive, check whether the belt is loose, slipping or broken, and adjust or replace it in time. Upgrade cooling capacity: For old equipment or devices operating under extremely harsh conditions, if the original cooler's capacity is insufficient, it is advisable to consider installing a larger-capacity or independently driven air-cooled cooler. If the set pressure of the relief valve is too high or the valve core is stuck in the pressure relief state, it will cause high-pressure oil to continuously return to the oil tank through the relief valve. This is a common cause of a sharp increase in oil temperature. It is recommended that professional maintenance personnel use a pressure gauge to detect the system pressure and readjust the relief valve according to the specified value. If the valve core is damaged, it needs to be cleaned or replaced. Hydraulic pump: Internal wear of the hydraulic pump (such as wear of the plunger, gears or blades) can lead to severe internal leakage. High-pressure oil leaked inside the pump into the low-pressure area, generating a large amount of heat. It is usually accompanied by phenomena such as weak machine power, slow movement and increased noise. Professional personnel are required to conduct efficiency tests. After confirmation, maintenance or replacement should be carried out. Control valve group: The wear of the valve cores of each control valve (such as directional control valves) can also lead to internal leakage, causing local high temperatures. One can touch the surface of the valve block to feel if there are any abnormal hot spots to assist in the judgment. Prevention from the perspective of usage habits is fundamental. Arrange the construction rhythm reasonably to avoid the equipment running at full load for a long time without interruption. When the working conditions are particularly heavy, it is necessary to consciously arrange intermediate rest periods to allow the hydraulic system to "catch its breath" and cool down. Daily: Clean the exterior of the cooler after work. Weekly: Check the hydraulic oil level and quality. Every six months or according to the working hours: Replace the hydraulic oil and filter element regularly as recommended by the manufacturer. This is the most effective means to prevent system contamination and oil deterioration. Solving the problem of excessively high hydraulic oil temperature in the power trowel machine is a systematic process. Please follow the principle of "start from the outside to the inside, from the easy to the difficult" : Begin with external factors such as cleaning the cooler and checking the oil level, as these often solve most problems. If it is ineffective, further investigate the core parameters such as the quality of the hydraulic oil and the setting of the relief valve. Finally, complex maintenance such as internal leakage of hydraulic pumps and valve groups should be considered. Adhering to standardized operation and regular maintenance is the fundamental way to prevent such problems from happening.   Note: The parameters provided in this document are for reference only and are not mandatory.
