The fan of the road sweeper is one of the key components of the road sweeper. Its performance determines the performance of the road sweeper to a large extent. Its air volume and air boost play a decisive role in the sweeping effect of the road sweeper. Its energy consumption or efficiency directly determines the fuel consumption of the road sweeper. Its performance parameters such as working noise, wear resistance, anti-dust ability, stable working range, and life span also directly determine the performance of the road sweeper, so we need to maintain and Maintain the road sweeper fan to reduce its wear rate.

The fan of the road sweeper deals with dust and dirt, so it is relatively a part with relatively large wear and tear. The following users of the road sweeper analyze how the road sweeper can improve and reduce the wear and tear of the wind turbine, and do a good job of daily maintenance.

When the road sweeper is working, the fan will suck air containing garbage and muddy water into the trash bin, but there will always be some dust, sand and water that cannot be completely separated from the air and directly enter the fan, forming a multiphase flow in the fan. Under the action of airflow and its own inertia, some small solid particles will inevitably impact the centrifugal impeller and the inner surface of the volute in the fan, causing wear of the fan impeller and volute. The wear of the impeller directly affects the performance and life of the fan, its dynamic balance is destroyed, the vibration is aggravated, and the noise during the operation of the fan increases.

Then, in order to slow down the wear of the fan impeller, the conventional method is to surfacing or spray wear-resistant materials on the corresponding wear-resistant parts, use wear-resistant steel, harden or carburize the surface of the material, select the air inlet reasonably, and try to avoid the use of hollow blades. Adding guide vanes, cutting the blade outlet into a sawtooth shape, etc. It is also possible to spray some special polymer materials on the surface of the sweeper fan to solve the problem of the abrasion of the sweeper fan.

The above is the method to reduce the wear of the fan of the road sweeper. Although it is inevitable that the fan of the road sweeper will be worn out, proper maintenance and maintenance can reduce the severity of wear and increase the service life.
