Uhlobo lweMveliso

1)Isalathiso sokujikeleza
I-LKB Series ventilator inokudityaniswa kwiindlela ezimbini zokujikeleza, ukujikeleza kwesobunxele (LG) kunye nokujikeleza kwesandla sokunene (RD);Ukujonga kwi-terminal ye-motor outlet, ukuba i-impeller ijikeleza ngasekunene, ibizwa ngokuba yi-ventilator yesandla sasekunene;Ukuba i-impeller ijikeleza ngokuchasene newotshi, ibizwa ngokuba yi-ventilator yesandla sasekhohlo.

2)Isalathiso seMpopo yoMoya
NgokukaFig 1, i-LKB Series ventilator inokwenziwa ngeendlela ezine zokukhupha umoya: 0°, 90°, 180°, 270°,

Ukwakhiwa kweMveliso

I-LKB Series ventilator ine-scroll, i-impeller, i-baseplate (isakhelo), i-motor, i-shaft sleeve kunye ne-flange yokuphuma emoyeni.
1)Skrola
Umqulu wenziwe kumgangatho ophezulu wentsimbi eshushu-galvanizing sheet.Amacwecwe asecaleni athatha imilo ngokwe-aerodynamics kwaye enze umthamo we-ventilator ubuncinci.Kwi-air inlet ye-side plate kukho i-air-inlet ukwenza umlambo womoya ungene kwi-impeller ngaphandle kokulahlekelwa.I-snail plate igxininiswe kwiiplate zecala ngendlela ye-welding yendawo okanye iluma ngokupheleleyo.Kwicwecwe elisecaleni lomqulu kukho uluhlu lwemingxuma egrunjwe kwangaphambili ukuze i-riveting nuts ukuphumeza ukufakwa ngokuhambelana nolwalathiso lwe-air outlet olufunwa ngumthengi.

2) Impeller
I-impeller yenziwe nge-high quality hot galvanizing steel sheet kwaye isayinwe kwi-configuration ekhethekileyo ngokuhambelana ne-aerodynamics ukwenza ukusebenza kakuhle okuphezulu kunye nengxolo ephantsi.I-impeller igxininiswe kwi-disk plate ephakathi kunye nentsimbi yokuphela kunye ne-riveting grippers.I-impeller ine-rigidity eyaneleyo ngexesha lokujikeleza okuqhubekayo kunye namandla aphezulu.Ngaphambi kokushiya i-factory, zonke i-impellers ziye zadlula zonke iimvavanyo zokulinganisa okuguquguqukayo ngokoMgangatho weNkampani ophezulu kunoMgangatho weSizwe.

3) Isiseko (Isakhelo)
I-LKB Series ye-ventilator baseplate yenziwe ngeshiti lentsimbi etshisayo ekumgangatho ophezulu.Ulwalathiso lofakelo lwe-baseplate lunokwenziwa ngokweemfuno ezahlukeneyo zabathengi.Ngaphezu kwe-LKB ye-315 isakhelo se-ventilator senziwe ngentsimbi ye-angle kunye ne-flatsteel.Kumacala amane esakhelo kukho imingxuma egrunjiweyo yofakelo ukuhlangabezana neemfuno zabathengi kwiindlela ezahlukeneyo zokufakela.

4) Imoto
I-motor esetyenziswa kwii-LKB series fans yingxolo ephantsi yesigaba sesithathu se-asynchronous motors ezine-rotors zangaphandle.I-impeller ifakwe kwi-casing yangaphandle ye-motor.Isantya sokujikeleza kwemoto sinokutshintshwa ngokusetyenziswa okubonelelwe ngamanqanaba amathathu ombane rhoqo, alawulwa ngesilicon.Isilawuli se-voltage, isiguquli se-frequency kunye nokunye ukwanelisa umthwalo oguqukayo kwinkqubo.

5) Flange
I-flange yenziwe ngentsimbi eshushu ye-galvanizing angle.Ukudityaniswa kweentambo zentsimbi ye-angle kunye nokudibanisa phakathi kwe-flange kunye nomqulu wenziwa ngokusebenzisa iteknoloji ye-TOX engekho-welding, ngaloo ndlela ifumana ukubonakala kakuhle, ukuqina okwaneleyo kunye namandla.Imilinganiselo kunye nodidi lweflange luboniswe kwiFig2.

Ukusebenza kweVentilator

1)Ukusebenza kwe-ventilator kule khathalogu kubonisa ukusebenza kwiimeko eziqhelekileyo.Ichaza iimeko zokungena komoya ze-ventilator ngolu hlobo lulandelayo:
Uxinzelelo lwe-air inlet Pa = 101.325KPa
Ubushushu bomoya t = 20lD
Uxinaniso lwegesi yokungena p = 1.2Kg/m3
Ukuba iimeko zokungenisa umoya ezisebenzayo zomthengi okanye isantya se-ventilator esebenzayo siyatshintsha, uguqulo lunokwenziwa ngokwale ntetho ilandelayo:

apho:
I-1) Umthamo we-Qo (nWh), uxinzelelo olupheleleyo lwe-Po ( Pa), i-speed n ( r / min), kunye ne-Nino ( kw) inokufumaneka kwitshathi yokuSebenza.
I-asterisk (*) kwikona ephezulu ngasekunene ibonisa iparamitha yokusebenza efunwa ngabathengi kwiimeko zokungenisa igesi.
Umahluko kumswakama onxulumeneyo awufakwanga kwezi fomyula zikhankanywe ngasentla.

2) Ukusebenza kwe-ventilator yesampula ivavanywa ngokuhambelana ne-GB1236-2000.Isalathisi sayo sengxolo silinganiswa ngokwe-GB2888-1991 kwinqanaba le-1 imitha ukusuka kwindawo yokungena.
I-asterisk (*) kwicala eliphezulu lasekunene i-comedenotes iparamitha yokusebenza efunwa ngabathengi kwiimeko zokungenisa igesi.

Imiyalelo

1) Ukuthelekisa amandla ombane ombane we-ventilator abonisa amandla angaphakathi kunye ne-coefficient yokhuseleko yomthamo wemoto yombane kwimeko ekhethekileyo yokusebenza, ayibonisi amandla afunekayo ngexesha lokuvulwa ngokupheleleyo kwendawo yokuphuma komoya.Ke ngoko akukho mthwalo wokuqhuba i-ventilator ngaphandle kokuchasana okusetyenzisiweyo akuvumelekanga ngokungqongqo ukunqanda ukutshisa ngaphandle kwemoto okubangelwa kukusebenza kwayo ngamandla alinganisiweyo ngaphezulu.

2)Le fan inqandelwe ukusetyenziswa kwiindawo apho izinto zomoya zingonakalisi, zingenatyhefu kwaye zingezo-alkaline okanye apho amaqela othuli <150mg/m3,-10°C

3) Ngaphambi kokufaka i-ventilator, jikeleza i-impeller ngesandla okanye unamathele ukujonga ukuqina okanye impembelelo.Ukuba kuqinisekiswa ukuba akukho bunzima kunye nefuthe, ngoko ke ukufakela kunokwenziwa.

I-4) Uqhagamshelwano oluthambileyo phakathi kombhobho womoya kunye ne-ventilator air-inlet kunye ne-outlet kufuneka yenziwe ngokusemandleni.Amalungu akufanele aqiniswe kakhulu.

5) Emva kokufaka, i-ventilator, umqulu we-ventilator kufuneka uhlolwe.Akufuneki kubekho izixhobo kunye nemiba eyongezelelweyo eseleyo kwi-casing.

6) Ngaphambi kokusebenza ngokusemthethweni kokungena komoya, kuyimfuneko ukujonga indlela ejikelezayo yeemoto zombini kunye ne-ventilator yokulungelelaniswa kwazo.

7) Ngexesha lokuodola kuyimfuneko ukuchaza uhlobo lwe-ventilator, isantya, umthamo womoya, uxinzelelo lomoya, indlela yokuphuma komoya, indlela ejikelezayo, uhlobo lwemoto yombane kunye neenkcukacha zayo.
