A Complete Guide to Synchronous Seal Carpet Maintenance: Practical Tips for Extending Equipment Lifespan As a key piece of equipment in highway maintenance, the synchronous seal carpet faces particularly stringent challenges in operating under complex road conditions at high altitudes, putting its performance and lifespan under extreme conditions. Mastering scientific maintenance methods not only ensures construction efficiency but also effectively reduces equipment failure rates. The following details the key points of synchronous seal car maintenance from three dimensions: daily inspection, core component maintenance, and seasonal maintenance.
Daily inspections should be thorough, focusing on tire pressure, drive belts, and the hydraulic system. In high-altitude areas, the large temperature difference between day and night easily affects tire pressure. Before driving, a high-precision tire pressure gauge should be used to check the tire pressure to ensure it meets the manufacturer's standard (usually 8-10 bar) to avoid accelerated tire sidewall wear due to insufficient tire pressure. The drive belt is the "bridge" for power transmission. During inspection, check for cracks and looseness. If the belt surface has more than 3 cracks or the deformation exceeds 5mm when pressed, it should be replaced immediately. The quantity and cleanliness of the hydraulic fluid are equally crucial. Before daily operation, check the oil level gauge in the tank; if the oil level is below 1/4 of the mark, replenish the hydraulic fluid promptly. Simultaneously, observe the oil for emulsification or impurities; if any abnormalities are found, immediately stop the machine and investigate.

Maintenance of core components is essential, with special attention required for the heating system and mixing device. The asphalt heating cylinder of the synchronous seal vehicle is a high-temperature operating component; clean the cylinder walls weekly to remove any remaining charred material. Use a dedicated scraper in conjunction with a high-pressure water gun to wash it, preventing carbon buildup that could affect heating efficiency. If the burner nozzles are clogged, it will lead to poor fuel atomization; disassemble and inspect them monthly, soaking them in diesel fuel to clear any blockages. The blades and mixing shaft of the mixing device are wear parts; clean any remaining gravel between the blades after operation. Check the blade wear quarterly; when the blade thickness is less than 2/3 of its original thickness, replace the wear-resistant liners promptly to prevent uneven mixing that could affect the seal quality.
Seasonal maintenance is also essential, and specific measures are required for high-altitude climates. In high-altitude areas, winter temperatures often drop below -15℃. Before starting the engine, the cooling system must be "antifreeze" treated by replacing the antifreeze with one that has a freezing point below -30℃. The battery charge should also be checked to ensure the starting voltage is consistently above 12V. In summer, with strong ultraviolet radiation and high road surface temperatures, the radiator surface should be cleaned regularly, and every 50 hours of operation, compressed air should be used to blow away debris from the radiator fins to prevent overheating due to poor heat dissipation. Furthermore, before the rainy season each year, the rust-proof coating on the chassis should be inspected, and exposed areas should be re-sprayed with rust-proof paint to prevent corrosion of metal components by high-altitude rain and ultraviolet radiation. By implementing these maintenance measures, the lifespan of the synchronous sealing vehicle can be extended by more than 30%, allowing the equipment to continue to perform at a high efficiency in highway construction in high-altitude areas.
