Medium Frequency vs AC Spot Welding Machine: Osobola okukekkereza ssente mmeka ku masannyalaze mu myaka 5?

Nga abakola ebintu bakyagenda mu maaso n’okussa essira ku kukendeeza ku nsaasaanya n’okukola obulungi emirimu, kkampuni nnyingi zitunuulira okusukka omuwendo gw’okugula nga ziteeka ssente mu aekyuma ekiweta ebifo. Ku layini z’okufulumya ezikola enkumi n’enkumi za weld buli lunaku, enkozesa y’amasannyalaze efuuka ensonga enkulu mu nsaasaanya yonna ey’emirimu. Mu myaka etaano, ne bwe wabaawo enjawulo entonotono mu kukozesa amaanyi amalungi esobola okuvvuunulwa mu kukosebwa okw’amaanyi mu by’ensimbi.

Ekitundu kino kiddamu ekibuuzo eky’omugaso:Amasannyalaze mmeka g’osobola okukekkereza mu myaka etaano ng’okozesa ekyuma ekiweta mu bifo eby’enjawulo (medium frequency spot welding machine) bw’ogeraageranya n’ekyuma eky’ennono ekya AC spot welding machine?Nga tukozesa data y’emirimu epimibwa n’enkola y’omuwendo gwonna ogw’obwannannyini (TCO), tujja kugeraageranya tekinologiya bombi wansi w’embeera entuufu ey’okufulumya era tuwa obulagirizi obusobola okukolebwa okuwagira okusalawo kwo mu kulonda ebyuma.

AC Spot Welding Machine Enzimba y'amasoboza

Ekyuma kya AC spot welding kikola ku 50/60 Hz era kyesigamye ku transformer eya bulijjo eya laminated core okukendeeza ku voltage n’okutuusa current enkulu. Olw’okuba firikwensi y’okukola ntono, tulansifooma nnene nnyo era efuna okufiirwa kwa magineeti n’ekikomo okw’amaanyi. Mu mbeera z’amakolero ez’omugaso, okutwalira awamu obulungi bw’okukyusa amaanyi butera okuba wakati wa 50% ne 60%.

Kino kitegeeza nti kumpi kitundu ky’amasoboza g’amasannyalaze agaggibwa mu giridi gabula ng’ebbugumu okusinga okukyusibwa okufuuka amasoboza ag’okuweta amalungi. Wadde ng’okufiirwa kuno kuyinza obutalabika nga kukulu nnyo mu kiseera ky’okukola okw’ekiseera ekitono, kufuuka kwa maanyi mu by’ensimbi mu mbeera z’okufulumya ezitasalako.

Medium Frequency Spot Welding Ekyuma Enkizo mu kukola obulungi

Ekyuma ekiyitibwa medium frequency spot welding machine kikozesa tekinologiya wa inverter ekola waggulu wa 1,000 Hz. Amaanyi ga AC agayingira gasooka kulongoosebwa ne gafuuka DC oluvannyuma ne gakyusibwa nga gayita mu transformer ya medium frequency nga tegannaba kutuusibwa ku electrodes. Frequency y’emirimu eya waggulu ekendeeza nnyo ku sayizi ya tulansifooma n’okufiirwa kwa magineeti, okulongoosa obulungi bw’enkola okutwalira awamu okutuuka ku bitundu nga 85%–95%.

Okusinziira ku ndaba ya yinginiya, firikwensi eya waggulu erongoosa obulungi bw’okukyusa amasannyalaze n’okutumbula sipiidi y’okuddamu kwa kasasiro. N’ekyavaamu, wansi w’ebyetaago by’okuweta ebifaanagana, ekyuma ekiweta mu kifo kya frequency eya wakati kyetaaga amaanyi matono agayingizibwa okusobola okutuuka ku mutindo gw’okuweta gwe gumu. Enkizo eno ey’obulungi bw’enzimba y’ensonga enkulu lwaki ebyuma ebiweta ebifo ebikekkereza amaanyi-byongera okwettanirwa mu kukola ebintu ebingi-volume.

Obulung’amu bw’amasoboza tebusalibwawo bulungibwansi bwa kukyusa kwokka. Obudde bw’okuweta ye nkyukakyuka endala enkulu mu kubala amaanyi g’ekyuma ekiweta mu kifo.

Ebyuma bya AC bitera okwetaaga ebiseera ebiwanvu eby’okuweta kubanga obudde bw’okusituka kwa kasasiro buba mpola ate nga n’okutebenkera kw’enkula y’amayengo kuba wansi. Okugeza, nga oweta ekyuma ekigonvu ekya mm 1.0, obudde bw’okuweta butera okuba wakati wa sikonda 0.5 ne 0.6 okukakasa nti ensengekera ya nugget entuufu.

Ekyuma kya medium frequency spot welding kisobola okutuusa peak current kumpi mu kaseera ako nga kikuuma stable output. Obudde bw’okuweta butera okukendeezebwa okutuuka ku sikonda 0.2–0.3 mu mbeera z’ebintu ze zimu. Okukendeeza kuno tekukoma ku kwongera ku bungi bw’okufulumya wabula era kukendeeza ku maanyi agakozesebwa buli weld.

Mu kugezesa okufulumya okwa nnamaddala wansi w’ebipimo ebigeraageranyizibwa:

• Amasoboza g’ekyuma kya AC agakozesebwa buli weld: nga 0.018 kWh
• Enkozesa y’amasoboza mu kyuma kya frequency eya wakati buli weld: nga 0.008 kWh

Singa layini y’okufulumya ekola welds 2,000 buli lunaku, enkola ya AC ekozesa kWh nga 36 buli lunaku, ate enkola ya medium frequency ekozesa kWh nga 16. Enjawulo ya kWh 20 buli lunaku ekuŋŋaanyizibwa mangu. Nga tufudde nti buli mwaka wabaawo ennaku 250 ez’okukola, enjawulo y’omwaka etuuka ku kWh nga 5,000.

Nga twekenneenya amasannyalaze ekyuma ekiweta mu kifo kye kikozesa, buli-data y’amasoboza ga weld kye kimu ku bipimo ebikulu okusaba okuva mu bagaba.

Bwe tugeraageranya ebyuma ebiweta frequency eya medium frequency ne AC spot welding, kampuni nnyingi zibalirira active energy consumption yokka era ne zibuusa amaaso influence ya power factor.

Ebyuma bya AC spot welding bitera okukola inrush current enkulu nga bitandise, nga typical power factor eri wakati wa 0.6 ne 0.8. Okusobola okutuukiriza omutindo gw’ebikozesebwa, abakola ebintu batera okuteeka ebyuma ebirala eby’okuliyirira amaanyi agakola (reactive power compensation). Mu bitundu ebimu, low power factor eyinza okuvaamu ebibonerezo by’ensimbi oba okulongoosa enkola y’amasannyalaze okukakatako.

Ebyuma ebiweta ebifo ebya frequency eya wakati, olw’ensengekera yaabyo ey’okufulumya DC erongooseddwa, bitera okukola n’ensonga y’amaanyi okumpi ne 1.0. Zikola situleesi ntono ku mudumu gw’amasannyalaze era zikuuma embeera za vvulovumenti ezitebenkedde. Ku bifo ebiddukanya ebyuma ebiweta ebingi omulundi gumu, enkizo eno ey’enzimba tekendeeza ku kufiirwa maanyi gokka wabula n’ebisale by’ebizimbe.

N’olwekyo, okugeraageranya kwonna okw’omuwendo gw’ekyuma ekiweta mu kifo eky’emyaka etaano-kulina okubeeramu omulimu gw’ensonga y’amaanyi ng’ekitundu ky’ekyokulabirako ky’okwekenneenya.

Okusobola okuwa okubalirira okw’omugaso okw’emyaka etaano-okukekkereza amasannyalaze, lowooza ku mbeera eno wammanga:

Ebiteberezebwa:

• Obusobozi bw’ekyuma: 100 kVA
• Ennaku z’okukola buli mwaka: 250
• Omuwendo gwa weld buli lunaku: welds 2,000
• Omuwendo gw’amasannyalaze mu makolero: $0.14 buli kWh (okugeza omuwendo; tereeza okusinziira ku kitundu)

Okusinziira ku average buli-weld data data:

• Ekyuma kya AC spot welding kikozesa kWh nga 9,000 buli mwaka, ekivaamu amasannyalaze okusaasaanya ddoola nga 1,260 buli mwaka.
• Ekyuma ekiyitibwa medium frequency spot welding machine kikozesa kWh nga 4,000 buli mwaka, ekivaamu amasannyalaze agasaasaanyizibwa buli mwaka nga ga doola nga 560.
• Okutereka buli mwaka buli kyuma: nga doola 700.
• Emyaka etaano-okutereka buli kyuma: nga $3,500.

Ku kifo ekikola ebyuma 10, okukekkereza kw’amasannyalaze okw’emyaka etaano- kuyinza okusukka doola 35,000. Ensonga endala bwe ziteekebwamu-nga okukendeeza ku kwambala kw’obusannyalazo, okulongoosa mu kukwatagana kwa weld, okukendeeza ku miwendo gy’okuddamu okukola, okweyongera ku sipiidi y’okufulumya, n’okukendeeza ku nsimbi eziteekebwa mu byuma by’amasannyalaze agakola-enkizo y’ensimbi okutwalira awamu efuuka nnene nnyo.

Mu makolero nga ebitundu by’emmotoka, ebisenge bya bbaatule, n’enkuŋŋaana ezitambuza amaanyi agatereka, nga frequency y’okuweta esinga, enjawulo mu nsaasaanya yeeyongera okweyoleka.

Okusinziira ku ndowooza y’okuddizibwa kw’ensimbi, ekyuma ekiweta mu bifo eby’enjawulo (medium frequency spot welding machine) kya mugaso naddala mu mbeera zino wammanga:

• Volume ya weld buli mwaka esukka welds 300,000.
• Okufulumya kukola ssifiiti eziwera oba enteekateeka ezitasalako.
• Ebikozesebwa mulimu ekyuma eky’amaanyi amangi-, ekyuma ekikoleddwa mu bbugumu-, oba ebipande ebisiigiddwa.
• Weld consistency ne current precision nsonga nkulu nnyo ku mutindo.
• Ebyuma ebingi bikola omulundi gumu mu nkola y’amasannyalaze y’emu.

Ku nkola z'okuddaabiriza eza frequency entono oba emisomo emitono-batch, ekyuma kya AC kiyinza okukyawa omuwendo omutono ogw'omu maaso. Naye mu mbeera z’okufulumya eby’obungi-obunene, okukekkereza amaanyi g’ekyuma ekiweta mu kifo ekya frequency eya wakati kitera okumalawo enjawulo mu bbeeyi mu myaka ebiri oba esatu.

Mu bufunzi

Enjawulo wakati wa frequency eya wakati n’ekyuma ekiweta AC spot si ya tekinologiya yokka-ya byanfuna. Okukyusa amasoboza okw’amaanyi, obudde obutono obw’okuweta, ensonga y’amaanyi erongooseddwa, n’okufiirwa kwonna okw’emirimu okutono bivvuunulwa butereevu mu kukendeeza ku nsaasaanya y’amasannyalaze mu bbanga.

Ku bakola ebyuma abeekenneenya ebyuma ebipya, ekikulu kwe kusaba data ezipima okusinga okwesigama ku specifications zokka. Nga tonnasalawo kugula, saba abagaba ebintu bino:

• Ekakasiddwa buli-data y’enkozesa y’amasoboza ga weld
• Enkokola z’enkozesa y’amasoboza mu buwanvu bw’ebintu obw’enjawulo
• Lipoota z’okugezesa ensonga y’amaanyi
• Okuteebereza kw'omuwendo gwonna ogw'emyaka etaano- okusinziira ku bungi bw'ebintu by'ofulumya

Ekyuma ekikola ‘spot welding machine’ si ssente za kapito yokka; ye nsimbi eziteekebwa mu mirimu egy'ekiseera ekiwanvu-. Bwe kyekenneenyezebwa mu myaka etaano-, okukozesa obulungi amaanyi kuyinza okukwata ennyo ku magoba okutwalira awamu.
