Pallet Jack BatteryKusankha Kwamphamvu: Load vs Runtime
M'miyezi 36 yapitayi takhala ndi mabatire akuluakulu a pallet jack pa ntchito 67 zosungiramo zinthu. Makumi anayi-atatu anabwera kudzera mu RFPs; makumi awiri-anayi anali kufutukuka kwa zombo kuchokera ku maakaunti omwe alipo. Sitingathe kutchula makasitomalawa. Zomwe titha kugawana poyera ndi mawonekedwe a mapulojekiti 14 pomwe kukula kwathu kunali kolakwika, chifukwa zolepherazo zidatitengera pafupifupi $180,000 m'malo mwa chitsimikizo ndipo zidatiphunzitsa zambiri za kusankha mphamvu kuposa 53 zomwe zidayenda bwino.
Moona mtima, $180K imeneyo ikadali yoluma. Koma njira ina inali yoipitsitsa: kulola zolakwika zomwezo zizichitika ndikunamizira kuti njira yathu inali yabwino. Sizinali. Bukhuli lilipo kuti lisinthe maphunziro okwera mtengo kukhala chimango chomwe mungagwiritse ntchito. Ngati mumagwiritsa ntchito zosungirako zoziziritsa kukhosi, -kusinthasintha, kapena kupitilira mayunitsi asanu, zina mwazinambalazi zisemphana ndi zomwe wopereka wanu wakupatsani.
Chani "Mphamvu"Zimakuwonongerani Ndalama Zikalakwika
Woyang'anira zogula akutengera mavoti a Ah chaka chatha pa RFP yatsopano akubetcha mwakachetechete $12,000-mpaka-$50,000. Mabatire ocheperako amafa pakati pa kusintha. Okulirapo amakhala pamenepo akuwotcha likulu. Timawona zonse ziwiri nthawi zonse.
Nachi chinthucho. Nambala ya 200Ah ija pa mawu anu? Kuyesedwa pamlingo wa kutulutsa kwa maola 20-, madigiri 25 osasintha , kusintha kwa ziro. Labu zinthu. Pallet jack yanu imakwera pa 4–6% padoko yodzaza ma 4,000 lbs, imakoka posungirako mozizira pa -madigiri 18 , ndipo imayenda mozungulira kwa maola asanu ndi atatu mpaka khumi ndi asanu ndi limodzi. Pazifukwa zenizeni, mphamvu zogwiritsiridwa ntchito zimatha kutsika mpaka 60% ya chiwerengerocho chisanafike malire akuya otaya ngakhale kulowa chithunzicho.
Kulemera kwa katundu sikusintha zomwe makina anganyamule. Ndiwo makina: chimango, mafoloko, silinda ya hydraulic. Zomwe kulemera kwa katundu kumasintha ndi momwe batire imathamangira mofulumira. Zolemba za Crown zosindikizidwa pa WP 3200 zikuwonetsa kutsika kuchokera pa 25% kutsitsa mpaka 10% pamlingo wovotera. Kuthamanga kwaulendo kumatsika 5.4% pansi pa katundu wathunthu. Pa Texlift US-EPT33K, kuchepetsa liwiro kumafika 19%. Awa ndi ma proxies owonjezera kukoka komwe kulipo, ndipo amaphatikizana pamlingo uliwonse wapallet pakusinthana. Opaleshoni yomwe ili ndi ma 4,000 lb ikukweza panjira imawotcha ndi mphamvu 30-40% mwachangu kuposa njira yomweyo yokhala ndi jack yopanda kanthu.
Kuzungulira kwa pallet pa 24V mu 2,000-4,000 lb kudutsa 50-150 mapazi oyenda kumawononga pafupifupi 5Ah. Mapallet makumi anayi patsiku, ndiko kufunikira kwa 200Ah yaiwisi. Zosavuta mokwanira. Koma mawu ambiri amayima pamenepo ndikumenya kukula kwa batri pamenepo. Ndiko kulakwitsa. Mphamvu yeniyeni yofunikira ndiyofunika ÷ kuya kwakuya kwamadzi otayira × kukonza kutentha × nkhokwe yowonongeka. Dumphani chochulutsa chilichonse ndipo mwachepera chaka chachiwiri. Tinaphunzira izi njira yodula.
Zolephera Kukula Zitatu Zomwe Zasintha Protocol Yathu
"Mapallet 30" omwe kwenikweni anali 90. Wothandizira wogawa chakudya adatiuza kuti amasuntha ma pallet 30 pa shift iliyonse. Timaganizira za 250Ah LiFePO4. Magawo awiri adayenda mophwanyika ndi ola lachisanu sabata yoyamba. Titafufuza pa-tsamba, tidapeza "mapallet 30" omwe amatanthawuza kulandila kolowera. Kutolera kwenikweni kunathyola phale lililonse lolowera m'madongosolo atatu kapena anayi otuluka. Kusuntha kwenikweni pakusintha kulikonse: kumpoto kwa 90. Tinasintha mapaketi pamtengo wathu ndi mayunitsi a 440Ah. Phunziro, ndi lokwera mtengo: tinasiya kuvomereza kuyerekezera kwapakamwa. Ntchito iliyonse tsopano ikufunika kutumiza data ya WMS kapena -masiku atatu pa{14}}kaundula wa ntchito zapatsamba tisanamalize zina.
Mufiriji yemwe amangokhalira kugona za state of charge. Izi zikutivutitsabe. Opaleshoni yamkaka pa -18 digiri, yoyerekeza ndi mapaketi a 400Ah pogwiritsa ntchito chowonjezera kutentha kwa 2.17 × kuchokera pamagome omwe adasindikizidwa. Zikadayenera kukhala zochuluka. Mayunitsi adamwalira pa ola la 5.5. Kusintha kulikonse. Galimoto iliyonse.
Zoyambitsa zinali zofutukuka patatu, ndipo kunena zoona tikadagwira osachepera awiri a iwo. Choyamba, magalimoto anali kuyenda panjinga pakati pa zoziziritsa kukhosi ndi doko lozungulira ola lililonse kuti alandire mapaleti atsopano. Kusintha kulikonse kunakakamiza mbale yotenthetsera ya BMS kuyatsa 8-12Ah ndikungoyang'anira ma condensation, mphamvu zomwe sitinawerengepo. Chachiwiri, BMS inali kuchulukirachulukira pansi pa -madigirii 12 , zomwe zinachititsa kuti injiniyo igwire ntchito yomweyo. Chachitatu - ndipo iyi ndi imene yatithandiza kwambiri - pansi pa 40 degrees F, batire yotsegula-circuit voltage ndi yokwera kwambiri. Gauge adawonetsa 40% yotsala. Ndalama zomwe zingagwiritsidwe ntchito zinali pafupi ndi 15%. Chaja chinali kutha msanga pazifukwa zomwezo, kutumiza magalimoto okwera theka kubwerera pansi.
Tinakweza ntchito yonseyo kukhala 630Ah yokhala ndi mbale zoyatsira moto. Tipatseni $40,000 pakukwaniritsa chitsimikizo. Lembaninso ndondomeko yathu yoziziritsa{5}}yosungirako kuyambira koyambira mwezi womwewo.
Kachitidwe kosinthira kamodzi komwe kakhala kosintha kawiri m'mwezi wachisanu ndi chitatu. Makasitomala amasinthidwa-pamodzi potengera dongosolo lawo lotsegulira. Tinakula molingana ndi 210Ah. Miyezi isanu ndi itatu pambuyo pake adakula mpaka magawo awiri popanda kuwonjezera mabatire. Pofika chaka chachitatu, kupalasa njinga mofulumizitsa kunali kutayitsa paketi mpaka pakufunika kusinthidwa. Ndalama zokwana $3,500 posankha 210Ah kuposa 315Ah pogula zidasintha kukhala $8,000 mtengo wosinthira koyambirira. Tsopano timafunsa wogula aliyense{13}}amodzi ngati kuwonjezera{14}}kusinthasintha kungatheke mkati mwa zaka zisanu. Ngati yankho liri inde kapena mwina, timatchula mphamvu zazikulu ndikufotokozera chifukwa chake muzokambiranazo.
Pambuyo pa izi ndi zosintha zina khumi ndi chimodzi (inde, khumi ndi zinayi) ndondomeko yathu idasintha. Palibenso kuyerekezera kwapaleti. Deta yogwira ntchito kapena kuwunika kwamasamba, nthawi. Timayika chowonjezera kutentha kwa 3.2 × m'malo afiriji m'malo mwa 2.17× yosindikizidwa yomwe makampani ena onse amagwiritsabe ntchito. Ndipo mawu aliwonse omwe atchulidwa pano ali ndi chitsimikizo cha nthawi yogwiritsira ntchito: ngati batire silikulipira kusintha komwe tidanenera, mtengo wokwezera uli pa ife. Tinayenera kupeza chidaliro chimenecho movutikira.
