Mea puhi DC ʻole palaki Centrifugal WS7040
ʻO ka WS7040 (na Ningbo Wonsmart) he mea puhi centrifugal DC brushless 12V/24V liʻiliʻi (70 × 40 × 37 mm) i hoʻolālā ʻia no ke kahe ʻana o ke ea ma ke kaomi kiʻekiʻe ma nā wahi paʻa. Loaʻa iā ia kahi motika brushless ʻekolu-pae me nā bearings pōpō NMB no ke ola lōʻihi, e hāʻawi ana i ka manawa awelika i ka hāʻule ʻana (MTTF) ma mua o 20,000 mau hola ma ka mahana o ka lumi. ʻOiai kona liʻiliʻi (~ 78–80 g), hiki iā ia ke milo a hiki i ~ 43,000 RPM, e hoʻopuka ana i ke kahe ʻana o ke ea a me ke kaomi nui e like me ka mea i hōʻike ʻia ma lalo nei:
- Uila a me ka hoʻokele: 12/24Hoʻokomo VDC (pono ka mea hoʻokele BLDC waho). Loaʻa i ka mea puhi nā mea ʻike Hall i kūkulu ʻia (60 pulse/rev) no ka pane wikiwiki pololei.
- Kahe ʻana o ka ea a me ke kaomi:A hiki i ka ~25 m³/h (kahe komo manuahi) ma 0 kPa, me ke kaomi paʻa kiʻekiʻe loa ma kahi o 6.0 kPa. Hōʻike nā kiʻikuhi hana i ka ~25 m³/h ma 35,000 RPM (kahe kahe manuahi) a me ~6.0 kPa ma 43,000 RPM.
- Ka wikiwiki a me ke au:Hana mai ~35,000 a i 43,000 RPM ma muli o ke kaumaha. Loaʻa ka pae o ke kaha huki o kēia au mai ~4.5 A (ma ke kahe nui loa) a i ~1.5 A (ma ke kaomi nui loa).
- Walaʻau:Ma kahi o 50–73 dBA (walaʻau holo manuahi ~73 dBA, ~70 dBA ma lalo o ke kaumaha kiʻekiʻe). Hōʻike ʻo Wonsmart i ka hoʻolālā walaʻau haʻahaʻa o ka mea puhi (kaulana no CPAP a me nā mea lapaʻau) ʻoiai ke wikiwiki kiʻekiʻe.
- Nā Ana a me ke Kaumaha:70 mm ke anawaena × 40 mm ke kiʻekiʻe (kino) me ka hohonu o kahi ʻaoʻao he 37 mm. ʻO ke kaumaha he ~78–80 g, kūpono no nā lako lawe lima.
- Kūkulu ʻana:Hale palakiko (PC) a me ka impeller. Motika brushless ʻekolu-ʻāpana (papa F insulation) me nā bearings pōpō NMB kiʻekiʻe. Ua hōʻoia ʻia ka mea puhi CE/RoHS/ETL etc..
- Ke ola holoʻokoʻa:Ua helu ʻia no ka hana mau a hiki i +60 °C, me MTTF >20,000 h (ma 20–25 °C). ʻAʻohe pono o ka mālama ʻana.
- Nā Palekana/Mana:Ma muli o ka hoʻohana ʻana i kahi mea hoʻokele waho, hiki i ka ʻōnaehana ke hoʻokō i ka hoʻoponopono wikiwiki (PWM a i ʻole 0–5 V), ka paleki, a me nā pale (over-current, over/under-voltage, stall).
Nā Hiʻohiʻona Koʻikoʻi (vs. ke kumu hoʻohālike 24V): ʻO ka WS7040-12-X200 ka ʻano 12V o ka moʻo WS7040 a Wonsmart. Ke hoʻohālikelike ʻia me ka WS7040-24-V200, holo ia ma 12V (no ka hoʻohana maʻalahi me ka pila a i ʻole nā lako 12V) ma kahi o 24V. Loaʻa iā lāua ʻelua ka kapuaʻi like 70 × 40 mm a me ka hoʻolālā puhi, akā ua hoʻonohonoho ʻia ka hana no ka hoʻokomo 12V. Loaʻa i ka mana 24V kahi kaomi kiʻekiʻe iki (6.5 kPa vs 6.0 kPa) a me ke kahe ʻana o ka ea like (~25–25.5 m³/h). Ma ka huli ʻana, huki ke kumu hoʻohālike 12V i ke au hou aku (1.5–4.5 A vs 0.8–2.7 A) e hoʻokō i ka hoʻopuka like. Loaʻa i nā kumu hoʻohālike ʻelua nā pae walaʻau like (~50–73 dBA). I ka hana maoli, makemake ʻia ka mea puhi 12V i kahi e loaʻa ai ka lako 12V wale nō (e like me ke kaʻa, nā mea uila lawe lima), ʻoiai ʻo ka ʻāpana 24V e kūpono i nā ʻōnaehana ʻoihana 24V. A i ʻole, ua like nā hiʻohiʻona (NMB bearing, brushless motor, long life, small size).

Nā noi
He kūpono ka WS7040-12-X200 no nā kikowaena soldering/rework ea wela a me nā mea hana like. Hiki i kona kahe ea wikiwiki a kiʻekiʻe ke hāʻawi i ka ea wela i kahi nozzle rework no ka wehe ʻana i nā ʻāpana a me ke soldering PCB. Ua papa inoa pololei ʻo Wonsmart i nā kikowaena soldering rework SMD ma waena o kāna mau pahuhopu. Ma waho aʻe o ke soldering, kūpono ka hoʻopuka kaomi kiʻekiʻe o ka blower i nā mea hana lawe lima a lima paha - e like me nā mea hoʻāʻo pila a i ʻole nā mea hoʻāʻo cell wahie, nā mika kaiapuni, a i ʻole nā mea hoʻoulu uila lawe lima - ma nā wahi āpau e hoʻohana ʻia ai kahi lako 12V. ʻO kaʻoiaʻiʻo, hoʻomaopopo ʻo Wonsmart i ka hoʻohana ʻana i nā mea lapaʻau CPAP a me nā ʻōnaehana cell wahie, e hōʻike ana i kona kūpono no nā mea liʻiliʻi e pono ai ke kahe ea mālie a paʻa.
ʻO nā hiʻohiʻona ʻē aʻe e pili ana i nā ʻōnaehana hoʻoluʻu liʻiliʻi a i ʻole nā ʻōnaehana kaohi kahe ʻana o ka ea: no ka laʻana, ka ea pae papa i loko o nā pā paʻa (nā keʻena kelepona liʻiliʻi a i ʻole nā keʻena mea hana), nā pamu laʻana ea lawe lima, a i ʻole nā ʻāpana HVAC/blower mini. ʻO kāna hana 12V e maʻalahi ai ka hoʻohui ʻana i loko o nā ʻōnaehana mana pākahi a i ʻole nā ʻōnaehana haʻahaʻa-voltage. I nā hihia āpau, ʻo ka hoʻolālā brushless paʻa o ka blower, ke ola lōʻihi a me ka maʻalahi o ka kaohi wikiwiki uila (PWM/voltage) e hāʻawi i ka hana hilinaʻi i nā wahi ʻoihana a me nā wahi lapaʻau.
Hōʻuluʻulu manaʻo:ʻO ka WS7040-12-X200 kahi mea puhi centrifugal liʻiliʻi 12V kūlana ʻoihana. Hoʻohui ia i ke kaomi static kiʻekiʻe (~6 kPa) a me ke kahe ʻana o ka ea (~25 m³/h) me kahi hoʻolālā haʻahaʻa. ʻO nā pono nui e komo pū me ka hana haʻahaʻa-walo, ke ola lōʻihi (NMB bearings, MTTF>20k hola), a me ka maʻalahi e hoʻokele ʻia e nā mea hoʻokele motika waho. ʻO kēia mau hiʻohiʻona e kūpono ia no nā kikowaena hana hou ea wela, nā lako hoʻāʻo lima, nā mea hoʻokele kahe ea lawe lima, a me nā noi ʻē aʻe kahi e pono ai ke kahe ʻana o ka ea 12V kiʻekiʻe.
