Ntchito Yomanga

LKB Series ventilator imakhala ndi mpukutu, chowongolera, baseplate (frame), mota, manja a shaft ndi flange yakutulutsa mpweya.
1) Mpukutu
Mpukutuwu umapangidwa ndi chitsulo chamtengo wapatali chotentha kwambiri.Ma mbale am'mbali amatenga mawonekedwe molingana ndi aerodynamics ndikupanga voliyumu ya mpweya kukhala yochepa.Pa air inlet ya side plate pali air-inlet kuti mpweya ulowe mu choyikapo popanda kutaya.Mbalame ya nkhono imakhazikika pazitsulo zam'mbali mwa njira yowotcherera mawanga kapena kuluma kwathunthu.Pa mbali mbale ya mpukutu pali angapo mabowo mokhomerera pasadakhale kuti riveting mtedza kuchita unsembe malinga ndi mpweya kubwereketsa malangizo zofunika ndi kasitomala.

2) Impeller
Chotsitsacho chimapangidwa ndi pepala lazitsulo lotentha kwambiri lotentha kwambiri ndipo limasindikizidwa ku kasinthidwe kapadera malinga ndi aerodynamics kuti ikhale yogwira mtima kwambiri komanso phokoso lochepa kwambiri.The impeller imakhazikika pa disk plate yapakati ndi kumapeto kwa mphete yokhala ndi riveting grippers.Chotsitsacho chimakhala ndi kukhazikika kokwanira panthawi yozungulira mosalekeza ndi mphamvu zambiri. Asanachoke kufakitale, zotulutsa zonse zadutsa mayeso ozungulira mozungulira molingana ndi Company Standard yomwe ili yapamwamba kuposa National Standard.

3) Baseplate (Fremu)
LKB Series ventilator baseplate imapangidwa ndi pepala lachitsulo chotentha kwambiri.Mayendedwe a unsembe wa baseplate akhoza kuchitidwa molingana ndi zofunika zosiyanasiyana makasitomala.Pa LKB 315 mpweya mpweya chimango anapangidwa ndi ngodya zitsulo ndi flatsteel.Pa mbali zinayi za chimango pali mabowo anabowoledwa kwa unsembe kukwaniritsa zofunika makasitomala mu njira unsembe zosiyanasiyana.

4) Moto
Ma motor omwe amagwiritsidwa ntchito mu mafani a LKB ndi phokoso lotsika ma motors atatu asynchronous motors okhala ndi zozungulira zakunja.Chotsitsacho chimayikidwa pa choyikapo chakunja cha injini.Kuthamanga kwa injini kutha kusinthidwa pogwiritsa ntchito ma voliyumu atatu okhazikika, oyendetsedwa ndi silicon.Voltage regulator, frequency converter ndi zina zambiri kuti akwaniritse katundu wosinthika mu dongosolo.

5) Flange
Flange imapangidwa ndi chitsulo chotentha cha galvanizing angle.Kulumikizana kwa zingwe zazitsulo za ngodya ndi kugwirizana pakati pa flange ndi mpukutu kumachitika pogwiritsa ntchito teknoloji yopanda kuwotcherera ya TOX, motero kupeza maonekedwe abwino, kukhazikika kokwanira ndi mphamvu.Miyeso ndi mtundu wa flange zikuwonetsedwa mu Mkuyu 2.

Kuchita kwa Ventilator

1) Magwiridwe a mpweya wabwino m'kabukhuli akuwonetsa magwiridwe antchito munthawi yake.Imatanthawuza mikhalidwe yolowera mpweya ya mpweya wabwino motere:
Mpweya wolowetsa mpweya Pa = 101.325KPa
Kutentha kwa mpweya t = 20lD
Kachulukidwe wa gasi wolowera p = 1.2Kg/m3
Ngati zinthu zolowera mpweya za kasitomala kapena kuthamanga kwa mpweya woyendetsa ntchito zikusintha, kutembenuka kungathe kuchitidwa molingana ndi mawu awa:

kumene:
1) Volume Qo(nWh), kuthamanga kwathunthu Po(Pa), liwiro n(r/min), ndi Nino(k) zitha kupezeka pa tchati cha Performance.
Nyenyezi (*) pakona yakumanja yakumanja ikuwonetsa gawo la magwiridwe antchito omwe makasitomala amafunikira m'malo olowera mpweya.
Kusiyana kwa chinyezi chocheperako sikunatchulidwe m'njira zomwe tafotokozazi.

2) Magwiridwe a makina opangira mpweya amayesedwa malinga ndi GB1236-2000.Phokoso lake laphokoso limayesedwa molingana ndi GB2888-1991 pamtunda wa mita 1 kuchokera pakulowera.
Nyenyezi (*) kumtunda kumanja kumabwera gawo la magwiridwe antchito omwe makasitomala amafunikira m'malo olowera mpweya.

Malangizo

1) Kufananiza mphamvu yamagetsi yamagetsi yamagetsi olowera kumatanthauza mphamvu yamkati kuphatikiza chitetezo chamagetsi amagetsi pamachitidwe apadera ogwirira ntchito, sizikutanthauza mphamvu yofunikira pakutsegula kwathunthu kwa mpweya.Chifukwa chake kusanyamula katundu kwa ma ventilator popanda kukana kulikonse ndikoletsedwa kuti asatenthedwe ndi injini chifukwa chakugwiritsa ntchito mphamvu zake mopitilira muyeso.

2) Fani iyi imaloledwa kugwiritsidwa ntchito m'malo omwe zinthu za mpweya sizikuwononga, zopanda poizoni komanso zopanda zamchere kapena kumene maphwando a fumbi <150mg/m3,-10°C

3) Musanayike mpweya wolowera mpweya, tembenuzani choyikapocho ndi dzanja kapena ndodo kuti muwone ngati kulimba kapena kukhudzidwa.Ngati zatsimikiziridwa kuti palibe zomangika ndi zovuta, ndiye kuti kuyikako kungathe kuchitika.

4) Kulumikizana kofewa pakati pa chitoliro cha mpweya ndi mpweya wolowera mpweya ndi potuluka kuyenera kupangidwa momwe kungathekere.Zolumikizira siziyenera kumangika kwambiri.

5) Mukayika, chowongolera mpweya, mpukutu wa mpweya uyenera kuwunikiridwa.Sipayenera kukhala zida ndi zina zowonjezera zotsalira mubokosi.

6) Asanagwire ntchito yovomerezeka ya mpweya wabwino, ndikofunikira kuyang'ana komwe kumazungulira kwa ma mota ndi mpweya wabwino kuti agwirizane.

7) Pakuyitanitsa ndikofunikira kunena mtundu wa mpweya wabwino, liwiro, kuchuluka kwa mpweya, kuthamanga kwa mpweya, komwe kumatuluka, komwe kumazungulira, mtundu wamagetsi amagetsi ndi mawonekedwe ake.
