Problems solved by technology

This type of pump has a common defect, that is, there are moving parts in the pump body; its power source, such as a motor, can only be installed near the pump body, so the pump body cannot work deep below the liquid surface. Due to the limitation of the suction range, these pumps cannot Work in deep water; in order to prevent clogging, it is sometimes necessary to install a filter device at the suction nozzle
Limited by its structure, it is easy to cause blockage of the filter device or the pump body, and the moving parts are easy to wear or even damaged, and the wear cannot be compensated
In particular, this type of pump cannot be used to pump lumpy or granular dry materials.

Embodiment Construction

[0020] as attached figure 1 Longitudinal structure sectional schematic diagram of the present invention and attached figure 2 As shown in the cross-sectional schematic diagram of the transverse structure of the present invention, the present invention includes a suction pipe 6, a pump body 14, and an output pipe 1. The whole pump is placed in the protective sleeve 2 and connected therewith as a whole. On the pump body 14, according to the order from the suction pipe 6 to the output pipe 1, that is, the material conveying direction, a nozzle jacket 5, a mixing pipe 4, and a diffusion booster pipe 3 are arranged on the same axis between the suction pipe 6 and the output pipe 1, and are set on the pump body 14. A cone-shaped annular nozzle 12 is formed between the inner conical surface of the nozzle overcoat 5 on the suction pipe 6 and the end of the suction pipe 6, and its conical shrinkage direction is directed from the suction pipe 6 to the output pipe 1. Jet pipe 7. The no...

Abstract

A pneumatic jet pump is prepared as setting nozzle jacket, mixing tube and diffusion pressurizing tube on the same axle between output tube and suction tube along sequence from suction tube to output tube on pump body; forming conical ring nozzle by internal conical surface of nozzle jacket sleeved on suction tube and end portion of suction tube, pointing contraction direction of cone form from suction tube to output tube and setting air jet tube on nozzle jacket.

Description

technical field [0001] The invention relates to a pneumatic jet pump, in particular to its pump body structure. Background technique [0002] Sewage pumps, submersible sewage pumps or swirl pumps are generally used when pumping liquids containing lumpy or granular materials or viscous liquids such as concrete, mortar, and sludge. This type of pump has a common defect, that is, there are moving parts in the pump body; its power source, such as a motor, can only be installed near the pump body, so the pump body cannot work deep below the liquid surface. Due to the limitation of the suction range, these pumps cannot Work in deep water; in order to prevent clogging, it is sometimes necessary to install a filter device at the suction nozzle. Limited by its structure, it is easy to cause blockage of the filter device or the pump body, and the moving parts are easy to wear or even damaged, and the wear cannot be compensated. In particular, this type of pump cannot be used for pum...
