Kodi ndi zinthu ziti zazikulu zomwe zimagwiritsidwa ntchito pa ventilator?

Ma parameter akuluakulu, omwe amadziwika ndi fan, ndi anayi: Kutha (V) Kupanikizika (p) Kuchita bwino (n) Liwiro la kuzungulira (n min.^-1)

Kodi Mphamvu ndi Chiyani?

Mphamvu ndi kuchuluka kwa madzi omwe amasunthidwa ndi fan, mu voliyumu, mkati mwa unit ya nthawi, ndipo nthawi zambiri amawonetsedwa mu m³/h, m³/mphindi., m³/sekondi.

Kodi Kupanikizika Konse ndi Chiyani ndipo ndingawerengere bwanji?

Kupanikizika konse (pt) ndi kuchuluka kwa kuthamanga kwa static (pst), mwachitsanzo mphamvu yofunikira kuti ipirire kukangana kosiyana ndi dongosolo, ndi kuthamanga kwa dynamic (pd) kapena mphamvu ya kinetic yomwe imaperekedwa ku madzi oyenda (pt = pst + pd). Kuthamanga kwa dynamic kumadalira liwiro la madzi (v) ndi mphamvu yokoka (y).

kupanikizika kwa fomula-dinamic

Kumene:
pd = kuthamanga kwamphamvu (Pa)
y = mphamvu yeniyeni ya madzi (Kg/m3)
v= liwiro la madzi pa khomo la fan lomwe limagwiritsidwa ntchito ndi makina (m/sec)

kupanikizika kwa mphamvu ya fomula

Kumene:
V = mphamvu (m3/sekondi)
A = chiyerekezo cha kutsegula komwe kumagwiritsidwa ntchito ndi makina (m2)
v= liwiro la madzi pa kutsegula kwa fan komwe kumagwiritsidwa ntchito ndi system(m/sec)

Kodi zotsatira zake ndi chiyani ndipo ndingaziwerengere bwanji?

Kuchita bwino ndi chiŵerengero pakati pa mphamvu zomwe fan imapeza ndi mphamvu zomwe zimalowa mu injini yoyendetsa fan.

njira yogwiritsira ntchito mphamvu yotulutsa

Kumene:
n = magwiridwe antchito (%)
V = mphamvu (m3/sekondi)
pt = mphamvu yoyamwa (KW)
P = kupanikizika konse (daPa)

Kodi liwiro la kuzungulira ndi chiyani? Kodi chimachitika ndi chiyani kusintha kuchuluka kwa ma revolutions?

Liwiro la kuzungulira ndi kuchuluka kwa ma revolutions omwe fan impeller imayenera kuyendetsa kuti ikwaniritse zofunikira pakugwira ntchito.
Pamene chiwerengero cha ma revolutions chimasiyana (n), pomwe mphamvu yokoka ya madzi imakhalabe yokhazikika (?), kusinthaku kumachitika:
Mphamvu (V) imagwirizana mwachindunji ndi liwiro la kuzungulira, chifukwa chake:

t (1)

Kumene:
n = liwiro la kuzungulira
V = mphamvu
V1 = mphamvu yatsopano yopezeka pakasinthasintha liwiro la kuzungulira
n1 = liwiro latsopano la kuzungulira

Kumene:
n = liwiro la kuzungulira
pt = kupanikizika konse
pt1 = kupanikizika kwatsopano komwe kumapezeka pakasinthasintha liwiro la kuzungulira
n1 = liwiro latsopano la kuzungulira

Mphamvu yoyamwa (P) imasiyana malinga ndi chiŵerengero cha kuzungulira kwa cube, chifukwa chake:

mphamvu_ yozungulira-liwiro-la-fomula_

Kumene:
n = liwiro la kuzungulira
P = mphamvu ya m'mimba
P1 = magetsi atsopano opezeka pakasinthasintha liwiro la kuzungulira
n1 = liwiro latsopano la kuzungulira

Kodi mphamvu yokoka yeniyeni ingawerengedwe bwanji?

Mphamvu yokoka yeniyeni (y) ikhoza kuwerengedwa pogwiritsa ntchito njira yotsatirayi

Kumene:
273 = zero yeniyeni (°C)
t= kutentha kwa madzi (°C)
y = mphamvu yokoka ya mpweya pa t C(Kg/m3)
Pb= kupanikizika kwa barometric(mm Hg)
13.59 = mphamvu yokoka ya mercury pa 0 C(kg/dm3)

Kuti zikhale zosavuta kuwerengera, kulemera kwa mpweya pa kutentha ndi kutalika kosiyanasiyana kwaphatikizidwa mu tebulo ili m'munsimu:

Kodi ndinu kampani yopanga kapena yogulitsa zinthu?

Inde, Ife Zhejiang Lion King Ventilator Co., Ltd. ndi kampani yopanga zinthu zaukadaulo yomwe ndi katswiri pa mafani a HVAC, mafani a axial, mafani a centrifugal, mafani oziziritsa mpweya, mafani aukadaulo ndi zina zotero kuti tigwiritse ntchito ma air conditioner, air ex-changer, ma coolers, ma heater, ma convector apansi, sterilization purifier, air purifier, medical purifier, ndi air cleaner, energy industry, 5G cabinet...

Kodi zinthu zanu zili pamlingo uti waubwino?

Tili ndi satifiketi ya AMCA, CE, ROHS, CCC mpaka pano.
Ubwino wapamwamba kuposa wapakati komanso wapamwamba kwambiri ndi zomwe mungasankhe pamitundu yathu. Ubwino wake ndi wabwino kwambiri, ndipo makasitomala ambiri ochokera kumayiko ena amawadalira.

Kodi kuchuluka kwanu kochepa kwambiri ndi kotani, munganditumizire zitsanzo?

Kuchuluka kwa oda yathu yocheperako ndi seti imodzi, zomwe zikutanthauza kuti oda yachitsanzo kapena oda yoyesera ndi yovomerezeka, tikukulandirani mwansangala kuti mubwere kudzaona kampani yathu.

Kodi makinawo angasinthidwe malinga ndi zosowa zathu, monga momwe angaikidwire pa logo yathu?

Ndithudi makina athu akhoza kusinthidwa malinga ndi zosowa zanu, Ikani chizindikiro chanu ndi phukusi la OEM likupezekanso.

Kodi nthawi yanu yotsogolera ndi iti?

Masiku 7 - masiku 25, zimadalira kuchuluka kwa zinthu ndi zinthu zosiyanasiyana.

Ponena za utumiki wogulitsa pambuyo pogulitsa, kodi mungathetse bwanji mavuto omwe anachitika kwa kasitomala wanu wakunja pakapita nthawi?

Nthawi zonse chitsanzo chisanapangidwe chisanapangidwe mochuluka;
Zinthu zonse zimachitidwa QC yokhwima ndikuyang'aniridwa musanatumize.
Chitsimikizo cha makina athu nthawi zambiri chimakhala miyezi 12, panthawiyi, tidzakonza nthawi yomweyo kuti titsimikizire kuti zida zosinthira ziperekedwa mwachangu.

Kodi nthawi yanu yoyankhira ili bwanji?

Mudzalandira yankho mkati mwa maola awiri pa intaneti kudzera pa Wechat, Whatsapp, Skype, Messager ndi Trade manager.
Mudzalandira yankho mkati mwa maola 8 osagwiritsa ntchito intaneti kudzera pa imelo.
Foni nthawi zonse imapezeka kuti ilandire mafoni anu.
