Abstract

The utility model discloses a herringbone blade impeller of a peripheral pump. The herringbone blade impeller is a wheel disk, a plurality of radial blades are arrayed on the outer edge part of the wheel disk, an included angle between the radial cross section of each blade and the wheel disk of the impeller is 35-50 degrees, the blades are uniformly distributed on the wheel disk of the impeller in a radial pattern, the other side of the wheel disk of the impeller is symmetrically provided with the same number of blades by taking a radial line passing through the root of each blade at the outer edge part of the wheel disk, and every two adjacent blades at the same side constitute a runner of the impeller. Due to adoption of the structure, an included angle between each blade and the wheel disk of the impeller is 35-50 degrees, so that the diffusion of low-speed flowing fluid and flowing-separation fluid in the runner can be limited and restricted effectively, in addition, a pushing role is played on the fluid near an outlet of the impeller, the pushing force works on the fluid to make the fluid produce additional kinetic energy so as to increase the flow speed of the fluid and reduce the nonuniformity of a flow field at the outlet of the impeller, and thus, the purposes of increasing the working efficiency of the impeller and expanding a high-efficiency zone of the impeller are achieved.

Description

Peripheral pump herringbone blade impeller

Technical field

The utility model belongs to the pump technical field, is specifically related to a kind of peripheral pump herringbone blade impeller.

Background technique

Peripheral pump belongs to vane pump; Mainly form by the pump housing, pump cover, impeller; Its impeller is that a disk outer rim partly is radial evenly distributed a plurality of radial blades; Form ring runner between the pump housing and impeller, suction port and exhaust port all at the excircle place of impeller, separate suction port and exhaust port with dividing plate between suction port and the exhaust port.The surface friction drag of straight radial blade and liquid is big, and liquid is big to the impact force of impeller during pump startup, and power consumption is high, and its inefficiency, liquid are difficult for from impeller, throwing away; The area of contact of straight radial blade and liquid is little, and impeller is little to the thrust of liquid, and its lift is low.

Summary of the invention

The utility model technical problem to be solved is the deficiency to above-mentioned existing technology, and a kind of peripheral pump herringbone blade impeller is provided, and it changes the shape and the structure of impeller blade, improves performance index such as lift of pump, efficient, increases the intensity of impeller blade.

The technological scheme that the utility model adopted is: a kind of peripheral pump herringbone blade impeller; It is a wheel disc; And a plurality of radial blades are arranged in its outer edge; Said blade each radially section become 35 ° to 50 ° angles with the hub disk face and be radial to be distributed on the hub disk, be the blade of symmetry axis with the radial line of the root of crossing this lateral lobe sheet at the opposite side symmetric arrangement similar number of hub disk, adjacent two blades of homonymy are formed a runner of impeller.

As preferably, the adjacent composition blade of both sides adjacent channels constitutes a herringbone.

As preferably, said vane thickness is 4 millimeters to 6 millimeters.

The beneficial effect of the utility model is: owing to adopted said structure, blade to become 35 ° to 50 ° angles with hub disk, effectively limitation and restriction the diffusion of liquid of the interior low speed flowing liquid of runner and flow separation; And near the fluid the impeller outlet played push effect; This thrust makes it produce additional kinetic energy and improves its flow velocity the liquid work done, reduces the ricing in impeller outlet flow field; Thereby reach the working efficiency that improves impeller, enlarge its high efficient area.

Among the figure: 1, impeller; 2, blade.

Embodiment

To combine accompanying drawing and specific embodiment that the utility model is done further explain below.

As depicted in figs. 1 and 2; A kind of peripheral pump herringbone blade impeller; It is a wheel disc, and its outer edge arranges a plurality of radial blades 2, and blade 2 thickness are 4 millimeters to 6 millimeters; Said blade 2 each radially section take turns card with impeller 1 and become 35 ° to 50 ° angles and be radial to be distributed on impeller 1 wheel disc; Radial line with the root of crossing this lateral lobe sheet 2 is the blade 2 of symmetry axis at the opposite side symmetric arrangement similar number of impeller 1 wheel disc, and adjacent two blades 2 of homonymy are formed a runner of impellers 1, and the adjacent composition blade 2 of both sides adjacent channels constitutes a herringbone.

Owing to adopted said structure, blade 2 becomes 35 ° to 50 ° angles with impeller 1 wheel disc, effectively limitation and restriction the diffusion of liquid of the interior low speed flowing liquid of runner and flow separation; And near the fluid impeller 1 outlet played push effect; This thrust makes it produce additional kinetic energy and improves its flow velocity the liquid work done, reduces the ricing of impeller 1 exit flow field; Thereby reach the working efficiency that improves impeller 1, enlarge its high efficient area.
