Arrimaha soo socda waa in fiiro gaar ah loo yeelo marka la dooranayo qalabka hawo-qaadista:

1.Go'aami nooca qalabka hawo-qaadista si waafaqsan ujeedada. Marka la qaadayo gaasaska daxalka ah, qalabka hawo-celinta ka-hortagga daxalka waa in la doortaa; tusaale ahaan, marka la qaadayo hawo nadiif ah, qalabka hawo-qaadista ee hawo-qaadista guud ayaa la dooran karaa; u qaado si fudud gaas qarxa ama hawo boodh leh Markaad isticmaalayso qalabka hawo-qaadista ee aan qarxin ama qalabka hawo-qaadista boodhka, iwm.

2.Marka loo eego mugga hawada loo baahan yahay, cadaadiska dabaysha iyo nooca la doortay ee qalabka hawo-qaadista, go'aami lambarka mashiinka qalabka hawo-qaadista. Marka la go'aaminayo nambarka mashiinka qalabka hawo-qaadista, waxaa loo tixgeliyaa in dhuumaha laga yaabo inay hawada ka soo baxaan, iyo xisaabinta lumitaanka cadaadiska nidaamka mararka qaarkood ma qummana, sidaas darteed xajmiga hawada iyo cadaadiska dabaysha ee qalabka hawo-qaadista waa in lagu go'aamiyaa sida waafaqsan formula;

    Dhuumaha hawada ee Silikoon Marro dabacsan,Dhuumaha filimka PU dabacsanaan kara

Mugga hawada: L'=Kl . L (7-7)

Cadaadiska dabaysha: p'=Kp . p (7-8)

Qaabka, L'\ P'- mugga hawada iyo cadaadiska hawada ee loo isticmaalo marka la dooranayo lambarka mashiinka;

L \ p - qiyaasta hawada iyo cadaadiska hawada ee nidaamka;

Kl - mugga hawada dheeriga ah oo dhammaystiran oo dhammaystiran, sahayda hawada guud iyo nidaamka qiiqa Kl=1.1, nidaamka saarista boodhka Kl=1.1 ~ 1.14, nidaamka gudbinta pneumatic Kl=1.15;

Kp - Cadaadiska dabaysha ee dheeraadka ah ee badbaadada, sahayda hawada guud iyo nidaamka qiiqa Kp = 1.1 ~ 1.15, nidaamka ka saarista boodhka Kp = 1.15 ~ 1.2, nidaamka gudbinta pneumatic Kp = 1.2.

3.Xirmooyinka waxqabadka ee qalabka hawo-qaadista waxaa lagu qiyaasaa heerka caadiga ah (cadaadiska atmospheric 101.325Kpa, heerkulka 20 ° C, heerkulka qaraabada 50%, p = 1.2kg / m3 hawada), marka xaaladaha waxqabadka dhabta ah ay ka duwan yihiin, hawo-qaadista naqshadaynta Waxqabadka dhabta ahi wuu isbeddeli doonaa (mugga hawadu isma beddeli doono), markaa cabbirrada waa in la beddelaa marka la dooranayo qalabka hawo-qaadista.

4.Si loo fududeeyo isku xirka iyo rakibidda qalabka hawo-qaadista iyo tuubooyinka nidaamka, jihada ku habboon iyo habka gudbinta ee marawaxada waa in la doortaa.

5.Si loo fududeeyo isticmaalka caadiga ah loona yareeyo wasakhowga sanqadha, hawo-mareeneyaasha leh qaylada hoose waa in la doortaa sida ugu macquulsan.
