Embodiment
Below in conjunction with accompanying drawing, invention is described further to explanation.
Segmentation inhalation type vacuumizes centrifugal blower, by support end bearing housing group (1), air inlet sealing (2), casing (3), dividing plate (4), guide plate (5), impeller (6), axle sleeve (7), main shaft (8), thrust step bearing case group (9), go out hermetic seal (10) and form; Its four impellers (6) are installed on main shaft (8) with three axle sleeves (7) successively interleaved series, main shaft (8) two ends fall within respectively in support end bearing housing group (1) and thrust step bearing case group (9), air inlet seals (2), dividing plate (4), guide plate (5) and goes out hermetic seal (10) and is installed in casing (3), and four impellers (6), three axle sleeves (7) are wrapped in casing (3) with main shaft (8) intermediate section.Adopt this to invent its machine volume and greatly reduce, its efficiency can reach 82%, has reduced energy consumption.
The casing of this embodiment (3) is upper and lower subdivision structure, guarantees that dividing plate (4), guide plate (5), impeller (6) remove and install convenient; Be provided with 3 different suction ports (11), casing (3) constitutes one-level with dividing plate (4) and sucks volute casing (12), secondary suction volute casing (13), three grades of suction volute casings (14), and is all convergence structure in arc.Operation is used and is realized three kinds of different degree of vacuum of single device generation, and rate of air sucked in required is large simultaneously, degree of vacuum is high; According to customer parameter, this equipment can meet more than three kinds and three kinds different degree of vacuum to be realized at same equipment, reduces field apparatus mounting cost, has also reduced the occupation of land face of equipment.
The one piece casting structure that the dividing plate of this embodiment (4) is comprised of one-level dividing plate (4a), secondary dividing plate (4b), three grades of dividing plates (4c), long stator (4d), short-range missile leaf (4e).Overall structure rigidity reinforced during its fan operation, the working life of improving complete blower.
On the one-level dividing plate (4a) of this embodiment, secondary dividing plate (4b), three grades of dividing plates (4c), be all provided with hollow (4f), hole (4g).Be provided with the total quality that hollow (4f) alleviates blower fan, accelerate the internal stresses release of foundry goods; Owing to vacuumizing, centrifugal blower internal operation gas differential pressure is large, on every grade of dividing plate, be drilled with hole (4g), with the gas pressure difference between balance hollow (4f) and runner, eliminated gas differential pressure to one-level dividing plate (4a), secondary dividing plate (4b), the strength of three grades of dividing plates (4c) in intensity.
The quantity of the long stator (4d) of this embodiment, the every one-level of short-range missile leaf (4e) is all 10 ~ 16, and equates with long stator (4d), short-range missile leaf (4e) quantity of one-level.Adopt advanced CFD software, the analysis of Comprehensive Experiment result, use after long stator (4d), short-range missile leaf (4e) and rational stator number, air-flow is prewhirled and is entered impeller by long stator (4d), short-range missile leaf (4e), the efficiency of blower at least improves 8%, has greatly lowered energy consumption during complete machine operation.
Shroud (6a) and the hub disk (6b) of the impeller of this embodiment (6) are variable section structure.Adopt this structure, impeller (6) is under high speed conditions, and the tension strength that its integral body is subject to reduces greatly, guarantees blower safety and stability more in running.
Therefore the segmentation inhalation type that, the present invention is a kind of long service life, rate of air sucked in required is large, degree of vacuum is high, volume is little, efficiency is high, energy consumption is low, single device can produce multiple different degree of vacuum vacuumizes centrifugal blower.
