Abstract
Double suction is dislocatedly distributed four flow passage impellers, there are two on each side runner, and two runners about axial line central symmetry, i.e. a runner is that another runner rotate 180 ° of gained centered on axial line, and the runner of two sides is that back-to-back be staggered 90 ° is distributed.Two sides impeller is offset because axial force is equal and contrary, theoretically axial force of impeller is zero, and two sides impeller dislocation arrangement and 360 ° of circumferencial direction water outlets caused by impeller can be greatly reduced due to blade exit thickness be unevenly distributed caused by hydraulic vibration.Double suction four flow passage impellers that are dislocatedly distributed can efficiently solve the excessive problem of single suction pump axial force, greatly promote the efficiency of sewage pump, have preferably mechanical property and the structural advantages being convenient to mount and dismount.
Description
Technical field
The invention belongs to water pump field, in particular to a kind of double suction is dislocatedly distributed four flow passage impellers.
Background technique
Sewage pump is mainly used for pumping sanitary sewage, industrial wastewater and the liquid containing solid particle and fiber, answer extensively
For industries such as municipal administration, light industry, chemical industry, building, mines.Common sewage pump has two kinds of blade wheel structures of single channel and dual channel,
It but is all single suction structure.Under same flow, lift and revolving speed, the impeller inlet flow of single suction pump is that double-suction pump impeller is unilateral
Twice of inlet flow rate, so single suction pump specific angular speed is big compared to double suction structure, it is single for the sewage pump compared with low lift
Sucking pump specific speed is too big, and be centrifuged pump specific angular speed it is too big when, the efficiency of pump is all lower, and single suction structure is there are biggish axial force,
The mechanical property of water pump and the service life of components are highly impacted, but also its application receives great limitation.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, the present invention provides a kind of double suction and is dislocatedly distributed four flow passage impellers, purport
It in the efficiency for greatly promoting sewage pump, while solving the problems, such as that single suction pump axial force is excessive, there is preferably mechanical property and dress
Tear convenient structural advantages open.
The technical solution adopted by the present invention to solve the technical problems is:
Double suction is dislocatedly distributed four flow passage impellers, and there are two runners for every side, and two runners are about axial line central symmetry, i.e., one
Runner is that another runner rotates 180 ° of gained centered on axial line, and the runner of two sides is to be staggered 90 ° to be distributed back-to-back.
Two sides impeller is offset because axial force is equal and contrary, and theoretically axial force of impeller is zero, and two lateral lobes
Wheel dislocation arrangement and 360 ° of water outlets of circumferencial direction caused by can greatly reducing impeller due to blade exit thickness are unevenly distributed
Caused by hydraulic vibration.
Beneficial effects of the present invention: double suction is dislocatedly distributed four flow passage impellers, can efficiently solve single suction pump axial force mistake
Big problem greatly promotes the efficiency of sewage pump, has preferably mechanical property and the structural advantages being convenient to mount and dismount.
Detailed description of the invention
Fig. 1 is the dual channel sewage impeller of pump of the prior art.
Fig. 2 is that double suction of the invention is dislocatedly distributed four flow passage impellers.
In figure: 1. runners, 2. axial lines.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
Double suction is dislocatedly distributed four flow passage impeller water pumps, and there are four runner (1) for impeller, and two runners (1) of every side are about axis
Heart line central symmetry, i.e., a runner (1) is rotated obtained by 180 ° for another runner (1) centered on axial line (2), and two sides
Runner (1) be to be staggered 90 ° and be distributed back-to-back.
Claims (1)
- Four flow passage impellers 1. double suction is dislocatedly distributed, it is characterised in that: there are two runners for every side, and two runners are about in axial line The heart is symmetrical, i.e. a runner is that another runner rotates 180 ° of gained centered on axial line, and the runner of two sides is back-to-back It is staggered 90 ° and is distributed.
