Kev lag luam tshuab tshuab tsis yog ib pawg khoom lag luam - lawv yog tsev neeg ntawm cov tshuab ua haujlwm sib txawv ntawm cov qauv kev ua haujlwm, qhov siab ntau, thiab daim ntawv thov. Nov yog tag nrho taxonomy uas txhua tus neeg yuav khoom yuav tsum nkag siab ua ntej txiav txim siab yuav khoom.
Nyob rau theem siab tshaj plaws, cov tshuab tshuab muab faib ua ob pawg hauv paus raws li qhov lawv ua rau huab cua: ** zoo hloov pauv ** thiab ** dynamic ** .
Qhov zoo tshem tawm blowers ua hauj lwm los ntawm cuab ib tug ruaj ntim ntawm huab cua thiab lub cev thawb nws los ntawm lub system. Sub- hom muaj xws li:
- **Cov hauv paus tshuab tshuab (ntxaib-lobe):** Ob daim duab-8 lobes tig rov qab. Flow yuav luag tas li tsis hais lub siab. Dominant nyob rau hauv pneumatic conveying thiab dej khib nyiab aeration saum 500 mbar.
- **Tri-lobe blowers:** Peb lub lobes es tsis txhob muaj ob, txo cov pulsation amplitude los ntawm ~40% piv rau ntxaib- lobe designs.
- **Screw blowers:** Ob intermeshing helical screws compress air progressively along their length. Quieter thiab muaj txiaj ntsig ntau dua li cov hauv paus hniav ntawm qhov siab tshaj 0.8 bar, tab sis tseem kim dua.
- **Rotary vane blowers:** zawv zawg vanes nyob rau hauv ib qho offset rotor tsim expanding thiab cog lus chambers. Compact, nruab nrab siab (txog 1.5 bar), siv nyob rau hauv lub tshuab nqus tsev ntim thiab luam ntawv.
Dynamic blowers ceev cua los ntawm lub impeller rotating thiab hloov ceev mus rau hauv siab. Sub- hom muaj xws li:
- **Centrifugal blowers:** Cua nkag axially thiab tawm radially. Forward-kov (siab ntim, tsis tshua muaj siab, 60-70% efficiency), rov qab- nkhaus (siab dua, 80-88% efficiency), thiab radial- hniav (particulate-tolerant) variants. Siv nyob rau hauv HVAC, plua plav sau, thiab combustion cua mov.
- **Regenerative blowers (ntiv nplhaib/sab channel):** Cua recirculates ntawm impeller hniav thiab ib sab channel, tau txais lub zog nrog txhua qhov dhau. Tib-theem (250–350 mbar), ob npaug-theem (450–600 mbar). Roj-dawb, compact, nruam- lub luag haujlwm muaj peev xwm.
- **Axial fans:** Air moves parallel to the shaft. High volume (>10,000 CFM), tsis tshua muaj siab (<50 mbar). Used for ventilation, cooling towers, and condenser air movement. Not considered true "blowers" in industrial contexts.
- **High-speed turbo blowers:** Permanent magnet motors spinning at 20,000–60,000 RPM on air-foil bearings. 85-92% efficiency, variable speed, tsis muaj kev sib cuag. Cov qeb tshiab tshaj plaws, tau txais kev koom nrog hauv cov dej khib nyiab loj.
Suav variations nyob rau hauv cov sub- hom - ib leeg vs ntau- theem, ncaj qha-tsav vs siv-tsav, qhib vs kaw impellers - tag nrho cov naj npawb tshaj **15 txawv configurations**. Tab sis rau cov tswv yim kev txiav txim siab, qhov kev xaiv yuav luag ib txwm txo mus rau peb: Cov hauv paus rau siab - siab, lav- cov ntawv thov ntws; centrifugal rau siab - ntim, ruaj- cov tshuab siab; thiab regenerative rau nruab nrab hauv av uas cov roj-dawb, tsis tu ncua, nruab nrab- kev ua haujlwm siab yog qhov tseem ceeb.
