Chimake chachikuluchopopera mpweyaya DN3000 ndi gawo lofunikira kwambiri pakulamulira makina akuluakulu opumira mpweya ndi mpweya（valavu yopopera mpweya(）). Imagwiritsidwa ntchito makamaka m'malo okhala ndi malo akuluakulu kapena kufunikira kwa mpweya wambiri monga mafakitale, ngalande zapansi panthaka, malo okwerera ndege, malo akuluakulu amalonda, ndi malo opangira magetsi otentha. Ntchito zake zazikulu zimayang'ana pa "kuwongolera mpweya molondola, kuonetsetsa kuti makinawo ali olimba, komanso kulimbikitsa chitetezo ndi kugwiritsa ntchito mphamvu moyenera". Itha kugawidwa m'magawo anayi:

A. Kusintha kolondola kwa kuchuluka kwa mpweya ndi kuthamanga kwa mpweya

M'malo akuluakulu, zofunikira pa mpweya wabwino m'malo osiyanasiyana zimasiyana kwambiri (monga, malo opangira zinthu m'malo opangira mafakitale amafunika mpweya wambiri kuti achotse kutentha, pomwe malo osungiramo mpweya amafunika mpweya wochepa kuti asinthe mpweya). Valavu ya mpweya ya DN3000 imatha kuwongolera bwino kayendedwe ka mpweya ndi kupanikizika kudzera mu payipi mwa kusintha tsamba lotseguka, kupewa mpweya wambiri kapena wosakwanira, kuonetsetsa kuti magawo a mpweya wabwino m'dera lililonse akukwaniritsa miyezo ya kapangidwe, komanso nthawi yomweyo kuchepetsa phokoso ndi kugwiritsa ntchito mphamvu komwe kumachitika chifukwa cha kusalingana kwa mpweya m'dongosolo.

B. Kudula kwa kayendedwe ka mpweya m'dongosolo ndi kuwongolera malo

Pamene makina akuluakulu opumira mpweya amafunika kukonzedwa, atatsekedwa m'malo osiyanasiyana kapena njira zosinthira (monga pamene makina opumira mpweya amasintha pakati pa nyengo yozizira ndi chilimwe), valavu yopopera mpweya ya DN3000 ikhoza kutsekedwa kwathunthu kuti "idule ndikulekanitsa" mpweya m'mapaipi kapena madera enaake, kuletsa mpweya wosakonzedwa kuti usayende ndikukhudza chilengedwe, komanso kuonetsetsa kuti ogwira ntchito yokonza zinthu ndi otetezeka.

C. Chitetezo ndi Kuyankha Mwadzidzidzi

Muzochitika zomwe zili ndi zoopsa za moto ndi kutayikira kwa mpweya woopsa (monga magaraji apansi pa nthaka ndi mafakitale a mankhwala), valavu ya DN3000 yopopera mpweya nthawi zambiri imalumikizidwa ndi makina oteteza moto: imatseka yokha zopopera mpweya m'malo osakhala utsi panthawi ya moto kuti moto ndi utsi zisafalikire. Mpweya woipa ukatuluka, tsekani valavu ya mpweya m'malo oipitsidwawo ndikutsegula njira yotulutsira mpweya mwachangu kuti mutulutse mpweya woipa mwachangu, kuchepetsa zoopsa zachitetezo, ndikutsata malamulo oteteza moto m'nyumba ndi chitetezo cha mafakitale.

D. Kulimbitsa magwiridwe antchito a dongosololi

Ngati makina akuluakulu opumira mpweya agwira ntchito mokwanira kwa nthawi yayitali, mphamvu zawo zidzakhala zambiri. Valavu ya mpweya ya DN3000 imatha kusintha kuchuluka kwa mpweya malinga ndi zosowa zenizeni (monga kuchuluka kwa antchito ndi katundu wopangidwa), kupewa kuwononga mphamvu. Pakadali pano, kapangidwe kake ka diameter yayikulu ndi koyenera kugwiritsa ntchito ma ducts amphamvu kwambiri, kuchepetsa kutayika kwa mpweya woyenda bwino pa valavu, kuonetsetsa kuti makina onse opumira mpweya akugwira ntchito bwino, ndikuchepetsa ndalama zogwirira ntchito komanso zosamalira za fan.
