Molten metal pump with filter |
摘要 |
A molten metal pump includes a filter that prevents ingestion of foreign material such as dross from molten metal within which the pump is immersed. The filter is a large structure that is secured to the base of the pump surrounding the pump's inlet. The filter forms a cavity adjacent the pump's inlet. The ratio of the surface area of the filter to the inlet area of the pump is very large due in part to a corrugated end wall included as part of the filter. The filter has a low porosity while maintaining a high flow rate for the pump.
