Decoded, Chapter 1 : The Wear Problem of Sweeper Suction Nozzle Walking Wheels: More Than Just Replacement Costs

As a core load-bearing component that directly contacts the ground, the wear problem of sweeper suction nozzle walking wheels has long plagued the industry—not only leading to frequent replacements and increased maintenance costs but also potentially causing fluctuations in the suction nozzle's ground clearance due to uneven wheel diameter, reducing cleaning efficiency (missed areas, decreased suction effect), and in extreme cases, even scratching the road surface (exposing the metal wheel core).

Through statistical analysis and failure assessment of 100 municipal sweeper trucks (operating hours 2000-8000 hours), the root causes of wear can be summarized into four categories, with their impact weights as follows:

Key Conclusion: Solving wear problems requires a systematic breakthrough from four dimensions: material upgrades, structural optimization, operating condition adaptation, and intelligent maintenance, rather than simply replacing individual parts.
