Zinthu zotsatirazi ziyenera kuganiziridwa posankha zida zopumira mpweya:
1.Dziwani mtundu wa zida zolowera mpweya malinga ndi cholinga.Ponyamula mpweya wowononga, zida zotetezera mpweya ziyenera kusankhidwa;mwachitsanzo, ponyamula mpweya wabwino, zida zopangira mpweya wabwino zimatha kusankhidwa;kunyamula mpweya wophulika mosavuta kapena mpweya wafumbi Mukamagwiritsa ntchito zida zopumira mpweya wosaphulika kapena zida zotulutsa fumbi, ndi zina zambiri.
2.Malinga ndi kuchuluka kwa mpweya wofunikira, kuthamanga kwa mphepo ndi mtundu wosankhidwa wa zida zopangira mpweya wabwino, dziwani kuchuluka kwa makina a zida zopangira mpweya.Podziwa kuchuluka kwa makina a zida zolowera mpweya, zimaganiziridwa kuti payipi imatha kutulutsa mpweya, ndipo kuwerengera kwa kuthamanga kwa dongosolo nthawi zina kumakhala kosakwanira, chifukwa chake kuchuluka kwa mpweya ndi mphamvu ya mphepo ya zida zopangira mpweya kuyenera kutsimikiziridwa molingana ndi chilinganizo;
Flexible Silicone Cloth air duct,Flexible PU film air duct
Kuchuluka kwa mpweya: L'=Kl .L (7-7)
Kuthamanga kwa mphepo: p'=Kp .p (7-8)
Mu chilinganizo, L'\ P'- voliyumu ya mpweya ndi kuthamanga kwa mpweya komwe kumagwiritsidwa ntchito posankha nambala ya makina;
L \ p - kuwerengera kuchuluka kwa mpweya ndi kuthamanga kwa mpweya mu dongosolo;
Kl - voliyumu ya mpweya yowonjezera yokwanira yokwanira, mpweya wokwanira ndi makina otulutsa mpweya Kl = 1.1, makina ochotsera fumbi Kl = 1.1 ~ 1.14, makina otumizira mpweya Kl = 1.15;
Kp - kuthamanga kwa mphepo zowonjezera zowonjezera chitetezo, mpweya wambiri ndi makina otulutsa mpweya Kp = 1.1 ~ 1.15, njira yochotsera fumbi Kp = 1.15 ~ 1.2, makina oyendetsa mpweya Kp = 1.2.
3.Zigawo zogwirira ntchito za zida zopangira mpweya zimayesedwa pansi pa chikhalidwe (kuthamanga kwa mlengalenga 101.325Kpa, kutentha kwa 20 ° C, kutentha kwa 50%, p = 1.2kg / m3 mpweya), pamene zochitika zenizeni zimakhala zosiyana, mpweya wabwino. kapangidwe Ntchito yeniyeni idzasintha (kuchuluka kwa mpweya sikudzasintha), kotero magawo ayenera kutembenuzidwa posankha zipangizo za mpweya wabwino.
4.Kuti athandizire kulumikizana ndi kukhazikitsa zida zopumira mpweya ndi mapaipi adongosolo, njira yoyenera yotulutsira ndi njira yopatsira faniyo iyenera kusankhidwa.
5.Pofuna kuwongolera kugwiritsa ntchito bwino komanso kuchepetsa kuwononga phokoso, ma ventilator okhala ndi phokoso lochepera ayenera kusankhidwa momwe angathere.
