Abstract

PURPOSE: For preventing the deformation in the operation of centrifugal pumps, to increase in mechanical strength the funnel-shaped guide plate made of a synthetic resin and communicating to a suction pipe by combining a reinforcing plate with said guide plate up to the latter's rising flat plate section.
CONSTITUTION: When an impellor 8 rotates, a centrifugal pump 1 sucks liquid through a suction pipe 3 and releases the liquid in said impellor 8 in four directions by centrifugal force. The flow of this pressurized liquid is discharged through the discharge pipe connected to a casing 5 while the flow lines thereof are rectified by a partition plate 10. At this time, there arises a difference between the liquid pressures on the both sides of the funnel-shaped guide plate 11 made of a synthetic resin and communicating to said suction pipe 3. However, said guide plate 11 is mechanically reinforced by the metal plate 12 combined with the outside of said guide plate 11 up to the former's rising plate section to become substantially free from deformatin. Thereby, operation can be made in safety since the contact accident between said impellor 8 and guide plate 11 is prevented securely.
