Although AV pumps cannot be equipped with exhaust valves and level gauges, they can meet on-site requirements through other means. AV pumps can be customized according to the limitations of equipment space, and the volume size can be adjusted according to needs. AV pumps are suitable for conveying distances that are relatively short, such as around 500 meters. Although the conveying capacity is not as good as MD pumps, AV pumps are still an effective choice in equipment with limited space. Overall, both AV pumps and MD pumps have their own characteristics and applicable ranges. Choosing the appropriate pump type based on specific scenarios and needs can effectively meet the transportation needs of fly ash under electrostatic precipitators. Warehouse type pneumatic conveying pump is a device that uses positive pressure pneumatic conveying method to transport powdered materials. It is widely used in the transportation of materials such as fly ash, cement, cement raw materials, and mineral powder in power plants. This pump can flexibly arrange the conveying pipeline according to the terrain conditions, achieving centralized, dispersed, high height, and long-distance material conveying. Moreover, during the transportation process, it is not affected by natural conditions, which ensures that the material will not get damp and will not cause pollution.
