Fan Assembly Sweeping : Cast Iron Pulley + Belt Drive Stability + Reasonable Transmission Ratio + Meet Sanitation Working Conditions

Functional Description of Zoomlion Sanitation Vehicle Fan Assembly (Impeller Blower)
As the core power component of road sweepers and sweeper-scrubber trucks, Zoomlion Sanitation Vehicle Fan Assembly is designed for garbage suction and cleaning operations, with core functions focusing on "high-efficiency suction, stable durability, and intelligent adaptation", as detailed below:
1 .Core Suction Power to Ensure Cleaning Efficiency: Adopting a centrifugal impeller design, it can output a large air volume of 7030-16000m³/h and a high total pressure of 5730-8600Pa, enabling quick suction of road garbage such as stones, dust, and fallen leaves (including solid particles with a diameter of ≤50mm). At the same time, it integrates a reverse blowing circulation system, which pushes residual sewage and garbage in the suction nozzle through reverse blowing air flow to avoid cleaning dead corners and improve road cleanliness.
2.Multiple System Protection to Extend Component Service Life: Equipped with a pneumatic multi-disc automatic clutch device, it automatically disengages during startup/shutdown to reduce motor impact and no-load wear. The impeller surface is coated with tungsten carbide wear-resistant coating, and combined with a three-stage pneumatic dust removal device (inertial sedimentation + pleated filter cartridge filtration + pulse dust cleaning), it not only reduces impeller loss but also achieves a dust filtration efficiency of over 99%. The suction nozzle bracket is equipped with an elastic buffer structure, which can automatically deflect by 15°-30° when encountering obstacles and then reset to avoid damage caused by hard collisions.
3.Intelligent Adaptation and Adjustment for Energy-Saving and Low-Noise Operation: It supports automatic switching between dry dust removal (sunny days) and wet cleaning (rainy days) modes to adapt to operations in different weather conditions. Adopting a short-blade diversion design + double-layer micro-hole muffler, the operating noise is controlled at 82-85dB(A). Through frequency conversion speed regulation technology, energy consumption is reduced by 18%-25% compared with traditional models. Built-in air pressure and temperature sensors monitor parameters in real time and automatically adjust power; when the filter cartridge is clogged, it triggers pulse dust cleaning and alarm.
4.Lightweight and Modular Design to Adapt to Multi-Scenario Needs: The impeller is made of Q345 low-alloy high-strength steel or aluminum alloy die-casting, which is 30% lighter than cast iron impellers and has 5 times higher corrosion resistance. The assembly adopts an integral hoisting modular design, and components such as impellers and bearing seats can be quickly disassembled, reducing maintenance time by 60%. It is compatible with multiple vehicle models such as road sweepers and sweeper-scrubber trucks with a wheelbase of 2600-5000mm, and can cope with extreme environments such as high altitude (3300-3600 meters) and low temperature (-20℃). The dust content of the exhausted gas is ≤10mg/m³, meeting environmental protection standards.
