Description

Technical Field

[0001] The utility model relates to the technical field of multistage pumps, in particular to a high-efficiency and energy-saving multistage pump. Background Art

[0002] A multistage pump is a centrifugal pump that is composed of an inlet and outlet water section and a middle section, which are combined together by a tie rod. Its output water pressure can be very high, and it also relies on the rotation of the impeller to obtain centrifugal force, so that the material is drawn out when the gas density reaches the working range of the mechanical vacuum pump, thereby gradually obtaining a high vacuum.

[0003] For example, the Chinese patent with publication number CN210240112U proposes a vertical multi-stage pump. This patent sets a guide plate at the outlet guide so that a small part of the medium that is difficult to form a backflow gradually forms a backflow under the action of the guide plate and the guidance of most of the medium, thereby reducing the capacity loss of the medium and preventing the particulate matter in the medium from settling on the outlet guide to form dirt. However, in this solution, since the output water pressure of the vertical multi-stage pump is relatively high during water delivery, a large amplitude vibration may occur during water delivery, and the head of the vertical multi-stage pump is heavy, so shaking may cause the vertical multi-stage pump to tilt and collapse.
