Shenhai Kuputika-Uchapupu
Iyo bt4 chiyero pamidziyo inoputika-yekudzivirira inoratidza maviri ekutanga paramita. Uyezve, iye 'b’ mu bt4 inoreva Kirasi IIb, zvichireva kushandiswa kwayo munzvimbo dzisiri dzemigodhi.

B
Iye 'B’ inoratidza mwero wegasi munharaunda, zvakatemerwa kuburikidza nekuyedza mareferensi mazinga. Iyi kupatsanurwa kunonyanya kukonzeresa migero mikuru iyo magasi anogona kupfuura uye neawo mashoma ekubatidza mafungu.. Yakaiswa muzvikamu zvitatu: Kirasi A, B, uye C. Nzvimbo dzeKirasi A dzakati chengetekei, Kirasi B ine njodzi zvakanyanya, uye Kirasi C ine njodzi, kunyange zvishoma. Kirasi C inoputika-yekudzivirira midziyo inoshanda munzvimbo dzese dzeKirasi A neB, Midziyo yeKirasi B inokodzera marongero eKirasi A, uye Midziyo yeKirasi A ndeye nharaunda dzeKirasi A chete. Semagumo, Kirasi B kazhinji ndiyo yakajairwa nhanho yemidziyo inoputika mumusika. Hurongwa hwemakirasi aya iKirasi C > Kirasi B > Kirasi A.
T4
T4 inoreva tembiricha kupatsanura mukati mezvakatipoteredza, zvichibva pamagasi’ hukama hwekubatidza nzvimbo. Kuiswa kwetembiricha yepamusoro kunoda kudzikira tembiricha yekushandisa uye kuomesesa kwemidziyo yakatarwa. Aya maclass akagadziridzwa kune chaiwo maitiro ekugadzira, zvinoda kusarudzwa kwemidziyo isingaputike kuti ienderane nemazinga chaiwo ekushisa kwezvakatipoteredza. T4-yakatemerwa michina yakagadzirirwa kushanda patembiricha kubva 135 kusvika 200°C.
Iyo bt4 explosion-proof rating ndiyo yakanyanya kuwanda, inopa kushandiswa kwakawanda uye sarudzo yakafara yenzvimbo dzinoshanda.
