Nthawi ya moyo imakhudzidwa ndi kutsatira malamulo otenthetsera, kutentha kwa malo ogwirira ntchito, komanso ngati chubucho chimakumana ndi nthawi yayitali yopanda ntchito popanda kukonzedwa bwino chikayambiranso.

Q8: Ndi mayeso otani a khalidwe omwe amachitidwa pa machubu a DXA X-ray asanatumizidwe?

Kuchokera kwa wopanga woganizira kwambiri za khalidwe, mayeso otumizira asanatumizidwe ayenera kuphatikizapo: mayeso opirira mphamvu yamagetsi apamwamba, kutsimikizira umphumphu wa vacuum, kuwonetsa mphamvu yamagetsi yotuluka pamalo ogwirira ntchito ovoteledwa, muyeso wa kukula kwa malo ofunikira, ndi njira yokalamba/yoyaka kuti mukhazikitse makhalidwe a mpweya wotulutsa. Pemphani malipoti oyesera — opanga odalirika amapereka izi ngati zikalata zokhazikika.

Q9: Kodi ndi ziphaso ziti zomwe wogulitsa chubu cha DXA X-ray ayenera kukhala nazo?

Pa kugula kwa B2B m'misika yolamulidwa: ISO 13485 (kasamalidwe kabwino ka zida zamankhwala), chizindikiro cha CE cha misika ya EU, ndi kulembetsa kukhazikitsidwa kwa FDA kwa njira zogawa ku US. Pa misika ina yadziko (China, Japan, Southeast Asia), ziphaso zina zakomweko zitha kugwiritsidwa ntchito. Nthawi zonse onetsetsani kuti kuchuluka kwa ziphaso kumaphatikizapo kupanga machubu a X-ray, osati ntchito zazikulu za kampani yogulitsa.

Q10: Kodi mitengo ya maoda ambiri imagwira ntchito bwanji, ndipo ndi kuchotsera kotani komwe kulipo?

Mitengo ya voliyumu imasiyana, koma mitengo yotsika mtengo nthawi zambiri imagwiritsidwa ntchito pamlingo wa mayunitsi 5, mayunitsi 10, ndi mayunitsi 20, ndi kuchotsera pang'onopang'ono kwa 8–20% kutengera mtundu wa chubu ndi wogulitsa. Mapangano apachaka okhudzana ndi kuchuluka kwa zinthu zomwe zaperekedwa nthawi zambiri amapereka mitengo yabwino kwambiri. Kwa ogulitsa omwe amayang'anira maakaunti a malo ambiri, mapangano okhudzana ndi kupereka zinthu zomwe zili ndi mitengo yokhazikika kwa miyezi 12 amatha kukambidwa ndi ogulitsa okhazikika.

Mapeto

Kusankha kumanjachubu cha X-ray choyezera mafupaKwa dongosolo la DXA ndi chisankho chokhala ndi zotsatira zomwe zimapitirira zomwe zimafunika kugula. Kulondola kwa muyeso wachipatala, moyo wautali wa dongosolo, chitetezo cha wodwala, ndi kupitiriza kugwira ntchito zonse zimadalira kuchita bwino izi.

Ndondomeko yogulira yomwe yafotokozedwa mu bukhuli — kutsimikizira kuyanjana, kufotokozera momwe ntchito ikuyendera, ziyeneretso za ogulitsa, ndi kasamalidwe ka moyo wonse — imagwira ntchito kaya mukusinthira chubu chimodzi mu chipatala cha anthu ammudzi kapena mukumanga pulogalamu yoperekera chithandizo cha netiweki ya DXA yapadziko lonse.

Kwa ogulitsa, malo okonzera zinthu, ndi ogula OEM omwe ali ndi zofunikira pa kuchuluka kwa zinthu, kukhazikitsa ubale ndi ogulitsa omwe amaphatikiza ukatswiri weniweni wa DXA tube engineering, njira zolembedwa bwino, komanso luso lodalirika la unyolo wogulira zinthu ndi chinthu chofunikira kwambiri, osati kugula zinthu.

Kodi mwakonzeka kukambirana zomwe mukufuna pa chubu cha DXA X-ray?

Tumizani funso laukadaulo ndi mtundu wa makina anu, zofunikira, ndi kuchuluka koyerekeza. Gulu lathu la mainjiniya lidzapereka chitsimikizo chogwirizana ndi mtengo wake komanso mtengo wovomerezeka mkati mwa maola 24 ogwira ntchito.
