I-DRK703 Umhloli wenkundla yeMask

Ukusetshenziswa Okuyinhloko

Ngokwamazinga afanelekile, isetshenziselwa ikakhulukazi ukuhlola inkundla yokubuka imaski, imaski kanye nemishini yokuphefumula, elungele abakhiqizi bemaski nabaphefumulayo, ukugadwa kwekhwalithi, ucwaningo lwesayensi, ukugqoka nokusebenzisa amayunithi.

Main izici

1. Yonke into esetshenziswayo yenziwe ngomnsalo we-semi-arc, idivayisi yokurekhoda, uhlaka lwesihlalo kanye nekhanda lokuhlola.
2. Umnsalo we-semi-arc: irediyasi (300-340) mm ingazungeziswa izungeza indiza engaba ovundlile idlula endaweni engu-0°, futhi isikali sidlulela ku-90° umnsalo we-arc njalo ngo-5° ukusuka ku-0° nhlangothi zombili, ifakwe indinganiso ebonakalayo emhlophe eshelelayo.
3. Idivayisi yokurekhoda: inaliti yokurekhoda ixhunywe nezinga lokubukwayo ngokusebenzisa izingxenye ezifana nesondo le-asisile, futhi isiqondiso kanye ne-Engeli yezinga lokubukwayo zirekhodwa kumdwebo wenkundla yokubuka ngokuhambisanayo.
4. Uhlaka lwesihlalo: lusetshenziselwa ukusekela umnsalo we-arc oyisiyingi kanye nedivayisi yokurekhoda engashintshi.
5. Hlola isikhunta sekhanda: isikhunta sekhanda esijwayelekile, izimbobo ezimbili zamehlo zesikhunta sekhanda zifakwe ama-bulb amancane, indawo ye-bulb kanye nesimo sekhanda lekhanda lihambisana nezidingo ze-GB 2890. Ukuhlolwa i-head die izofakwa ebhentshini lokusebenza ngendlela yokuthi amehlo angakwesokunxele nangakwesokudla abekwe phakathi nendawo ye-arch eyisiyingi futhi iphuzu elithi "0" libonakala ngokuqondile.

Izinkomba eziyinhloko

1. I-semi-circular arc radius: 335mm.
2. Inkambu yokubuka kwesokunxele nakwesokudla: ≤120°.
3. Ibanga le-bulb: i-vertex ye-bulb ixhunywe ngemva kwamaphoyinti amabili wamehlo (7±0.5).
