18. Chitsanzo chodzithandizira chokha: chikhoza kukhazikitsidwa pa malo a shaft ya silinda yoyaka moto ndipo imatha kuwongolera chitsanzocho.

19. Zosankha: Zitsanzo zonyamula zinthu zosadzithandizira: zimatha kukonza mbali ziwiri zoyimirira zachitsanzo pa chimango nthawi imodzi (zoyenera filimu ya nsalu ndi zipangizo zina)

20.M'munsi mwa yamphamvu kuyaka akhoza Mokweza kuonetsetsa kuti kutentha kwa mpweya wosakanizika anakhalabe pa 23 ℃ ~ 2 ℃

III.Mapangidwe a Chassis:                                

1. Bokosi loyang'anira: Chida cha makina a CNC chimagwiritsidwa ntchito pokonza ndi kupanga, magetsi osasunthika a bokosi lopopera zitsulo amapopera, ndipo gawo lolamulira limayendetsedwa mosiyana ndi gawo loyesera.

2. Silinda yoyaka: kukana kutentha kwambiri kwa galasi la quartz (m'mimba mwake ￠75mm, kutalika 480mm) M'mimba mwake: φ40mm

3. Zitsanzo zachitsanzo: zodzithandizira zokha, ndipo zimatha kugwira chitsanzocho molunjika; (Chimango chopanda chodzithandizira), magawo awiri azithunzi kuti akwaniritse zofunikira zosiyanasiyana zoyesa; Chitsanzo kopanira splice mtundu, zosavuta kuika chitsanzo ndi chitsanzo kopanira

4. Kutalika kwa dzenje la chubu kumapeto kwa choyatsira ndodo yayitali ndi ￠2±1mm, ndipo kutalika kwa lawi lamoto ndi (5-50) mm.

IV.Kukwaniritsa muyezo:

ASTM D 2863, ISO 4589-2, NES 714; Mtengo wa GB/T5454;GB/T 10707-2008;  GB/T 8924-2005; GB/T 16581-1996;NB/SH/T 0815-2010;TB/T 2919-1998; IEC 61144-1992 ISO 15705-2002;  ISO 4589-2-1996;

Chidziwitso: Sensa ya oxygen

1. Kuyambitsa sensa ya okosijeni: Pakuyesa kwa oxygen index, ntchito ya sensa ya oxygen ndiyo kutembenuza chizindikiro chamankhwala cha kuyaka kukhala chizindikiro chamagetsi chomwe chikuwonetsedwa kutsogolo kwa woyendetsa. Kachipangizo kameneka kamafanana ndi batire, yomwe imadyedwa kamodzi pa mayeso, ndipo kukweza kwafupipafupi kwa wogwiritsa ntchito kapena kukwezera mtengo wa oxygen wa zinthu zoyesera, m'pamenenso sensa ya okosijeni imakhala yochuluka kwambiri.

2. Kusamalira sensa ya okosijeni: Kupatula kutayika kwabwinobwino, mfundo ziwiri zotsatirazi pakukonza ndi kukonza zimathandizira kukulitsa moyo wautumiki wa sensa ya okosijeni:

1). Ngati zipangizozo siziyenera kuyesedwa kwa nthawi yaitali, mpweya wa okosijeni ukhoza kuchotsedwa ndipo kusungirako okosijeni kungapatulidwe ndi njira zina pa kutentha kochepa. Njira yosavuta yogwiritsira ntchito imatha kutetezedwa bwino ndi pulasitiki ndikuyika mufiriji.

2). Ngati zidazo zimagwiritsidwa ntchito pafupipafupi kwambiri (monga nthawi yozungulira masiku atatu kapena anayi), kumapeto kwa tsiku loyesa, silinda ya okosijeni imatha kuzimitsidwa kwa mphindi imodzi kapena ziwiri isanazimitsidwe silinda ya nayitrogeni, kotero kuti nayitrogeni adzadzazidwa ndi zida zina zosakaniza kuti muchepetse kusagwirizana kwa sensa ya okosijeni ndi kukhudzana ndi mpweya.

V.Kukhazikitsa tebulo: Kukonzedwa ndi ogwiritsa ntchito
