Cazuela de Vaca (Beef and Pumpkin Stew) This hearty Chilean stew of beef, corn, and pumpkin is a one dish meal. The main ingredients are stewed in serving-sized pieces, so that each person receives a large piece surrounded by a broth with the other vegetables.
Quick Answer. A rotary vane vacuum pump works by using centrifugal force to turn blades against the circular surface of a cylinder whereby pockets of air are pushed from an inlet port to an outlet port as air pressure increases.
The motor that drives the pump can work also as a generator; when it's working as a turbine, it collects the mechanical energy and transforms it into electricity. The VTG is particularly suited to where the head and flow are consisteng, and its main purpose is to fill small hydroelectric needs, and others.
