Straight elbow type double suction pump suction chamber

The utility model discloses a straight elbow type double-suction pump suction chamber which comprises a pump shell and a double-suction pump assembly, and the double-suction pump assembly comprises a suction chamber, a volute delivery chamber and a double-suction impeller. The inlet section of the suction chamber is in a straight cone shape, and the transition section and the head part of the suction chamber are in an elbow shape formed by arc lines, so that when a medium enters the double-suction impeller along the inlet section, the transition section and the head part of the suction chamber in sequence, the overflowing area of the medium at the inlet section is uniformly increased, the flowing speed is gradually increased, and the speed distribution is uniform; the overflowing area of the medium at the transition section and the head part is uniformly reduced, the speed is uniformly reduced, the distribution is uniform, and the hydraulic loss is reduced; an arc-shaped impact plate tangent to the outer wall
