Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 4 A conventional rotary jet pump includes a pump body 100, a rotor chamber 200, an impeller 300, a manifold 400, and a liquid inlet 500. The impeller 300 is fixedly connected to the rotor chamber 200. The rotor chamber 200 is driven to rotate by a motor, and the impeller 300 rotates to transfer the liquid from the The liquid inlet 500 is sucked into the interior of the rotor chamber 200, the rotor chamber 200 rotates at a high speed, the kin...

Abstract

The invention relates to the technical field of fluid transport pumps, and discloses a rotary jet pump for liquid transport, comprising a pump body, a rotor cavity is rotatably sleeved in the inner cavity of the pump body, and one side of the rotor cavity is fixed The impeller is connected, the inside of the pump body and the rotor cavity are fixedly sleeved with a collecting pipe, the inside of the pump body is provided with a liquid inlet, the side of the rotor cavity is provided with a permanent magnet, and the pump body A buffer tank is fixedly installed on the outer wall, and a diaphragm is fixedly connected to the inner wall of the buffer tank. The invention drives the diaphragm to deform in a wave shape through the attraction and repulsion of the permanent magnet and the permanent magnet block, thereby promoting the liquid flow in the buffer tank and exerting a certain pressure on the liquid, which helps the bubbles in the liquid to burst and reduces The content of gas and air bubbles in the liquid reduces the damage of the impeller and the inner wall of the rotor cavity due to cavitation, and prolongs the service life of the rotor cavity and impeller.

Description

technical field [0001] The invention relates to the technical field of fluid transport pumps, in particular to a rotary jet pump for liquid transport. Background technique [0002] At present, rotary jet pumps are widely used in petroleum, petrochemical, chemical, metallurgy, mining and other industries, especially in chemical processes, as chemical process delivery pumps. The rotary jet pump is mainly composed of a main shaft, a main shaft box, rolling bearings, a suction chamber, an impeller, a manifold and a rotor chamber. The impeller enters the rotor cavity, and then enters the inlet of the collector, where the kinetic energy of the liquid is converted into pressure energy for output. [0003] In liquid transportation, some liquids are mixed with a lot of gas and bubbles formed by gas clusters. In the rotor cavity, the bubbles adhere to the inner wall of the rotor cavity and the impeller. When the bubbles burst, the impact force will damage the structure of the rotor c...
