Le miba ilandelayo kufuneka ithathelwe ingqalelo xa ukhetha izixhobo zokungenisa umoya:

1.Misela uhlobo lwezixhobo zokungenisa umoya ngokwenjongo. Xa uthutha iigesi ezitshabalalisayo, izixhobo zomoya ezichasene ne-corrosion kufuneka zikhethwe; umzekelo, xa uthutha umoya ococekileyo, izixhobo zokungenisa umoya zokungenisa umoya jikelele zingakhethwa; ukuthutha ngokulula irhasi eqhumayo okanye umoya onothuli Xa usebenzisa isixhobo sokungenisa umoya esingagqabhukiyo okanye isixhobo sokukhupha umoya esikhupha uthuli, njl.njl.

2.Ngokomthamo womoya ofunekayo, uxinzelelo lomoya kunye nohlobo olukhethiweyo lwezixhobo zokungenisa umoya, misela inani lomatshini wezixhobo zokungenisa umoya. Xa kumiselwa inombolo yomatshini wezixhobo zokungenisa umoya, kucingelwa ukuba umbhobho unokuvuza umoya, kwaye ukubalwa kwelahleko yoxinzelelo lwenkqubo ngamanye amaxesha akugqibelelanga, ngoko ke umthamo womoya kunye noxinzelelo lomoya wezixhobo zokungenisa umoya kufuneka kumiselwe ngokwendlela yokuphefumla. ifomula;

    Flexible Silicone Ilaphu emoyeni umbhobho,Flexible PU ifilimu emoyeni umbhobho

Umthamo womoya: L'=Kl. L (7-7)

Uxinzelelo lomoya: p'=Kp . p (7-8)

Kwifomula, L'\ P'- umthamo womoya kunye noxinzelelo lomoya olusetyenziswa xa ukhetha inombolo yomatshini;

L \ p - umthamo womoya obaliweyo kunye noxinzelelo lomoya kwinkqubo;

I-Kl – umthamo womoya owongezelelweyo umlinganiso opheleleyo opheleleyo, unikezelo lomoya jikelele kunye nenkqubo yokukhupha i-Kl=1.1, inkqubo yokususa uthuli Kl=1.1 ~ 1.14, inkqubo yokuhambisa umoya Kl=1.15;

I-Kp – uxinzelelo lomoya into eyongezelelweyo yokhuseleko, unikezelo lomoya jikelele kunye nenkqubo yokukhupha Kp=1.1~1.15, inkqubo yokususa uthuli Kp=1.15~1.2, inkqubo yokuhambisa umoya Kp=1.2.

3.Iiparamitha zokusebenza kwezixhobo zokungenisa umoya zilinganiswa phantsi komgangatho oqhelekileyo (uxinzelelo lwe-atmospheric 101.325Kpa, ubushushu be-20 ° C, iqondo lokushisa elihambelana ne-50%, p = 1.2kg / m3 umoya), xa iimeko zokusebenza zangempela zihlukile, umoya wokungenisa umoya. uyilo Ukusebenza kwangempela kuya kutshintsha (umthamo womoya awuyi kutshintsha), ngoko iiparamitha kufuneka ziguqulwe xa ukhetha izixhobo zokungenisa umoya.

4.Ukuze uququzelele ukudibanisa kunye nokufakwa kwezixhobo zokungenisa umoya kunye nemibhobho yenkqubo, isikhokelo esifanelekileyo sokuphuma kunye nemodi yokuhambisa i-fan kufuneka ikhethwe.

5.Ukuze kuququzelelwe ukusetyenziswa okuqhelekileyo kunye nokunciphisa ungcoliseko lwengxolo, ii-ventilators ezinengxolo ephantsi kufuneka zikhethwe kangangoko kunokwenzeka.
