VERTICAL ROTARY PUMP Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: profiled reflector is located between inner wall of branch pipe and lateral wall of projection of housing. Reflector is made in form of elbow rounded at vertex. This elbow embraces discharge pipe and drain hole. Oil receiver is located on outer side of branch pipe and is secured with it. Inlet hole of oil receiver is brought in communication with drain hole and discharge hole is brought in communication with oil tank. Discharge hole is provided in lower wall of oil receiver and inlet hole is located under lower wall of oil receiver forming a projection. Base of elbow is located under pipe and is engageable with surfaces of housing and branch pipe forming continuous line of contact along base; base is fastened to upper end of housing. One side end of elbow adjoins inner surface of branch pipe and other side end adjoins lateral wall of projection. Lateral wall of elbow is located behind discharge pipe in way of rotation of pump and is inclined towards sense of rotation. Elbow is matched by radius at its vertex with circle of inlet section of drain hole. EFFECT: enhanced efficiency. 4 dwg
