Medium Frequency vs AC Spot Welding Machine: Kodi Mungapulumutse Ndalama Zingati pa Magetsi mu Zaka 5?

Pamene opanga akupitilira kuyang'ana kwambiri pakuchepetsa mtengo komanso magwiridwe antchito, makampani ambiri amayang'ana kupyola mtengo wogula akamagulitsamakina kuwotcherera malo. Pamizere yopanga ma welds masauzande ambiri patsiku, kugwiritsa ntchito magetsi kumakhala chinthu chachikulu pamtengo wokwanira wogwirira ntchito. Pazaka zisanu, ngakhale kusiyana pang'ono pakugwiritsa ntchito mphamvu zamagetsi kumatha kupangitsa kuti pakhale vuto lalikulu lazachuma.

Nkhaniyi ikuyankha funso lothandiza:Kodi mungasunge magetsi angati pazaka zisanu ndi makina owotcherera apakati pafupipafupi poyerekeza ndi makina azowotcherera amtundu wa AC?Pogwiritsa ntchito data yoyezera magwiridwe antchito komanso mtengo wokwanira wa umwini (TCO), tifananiza matekinoloje onsewa pansi pamikhalidwe yotheka kupanga ndikupereka chitsogozo chothandizira kusankha zida zanu.

AC Spot Welding Machine Energy Structure

Makina owotchera mawanga a AC amagwira ntchito pa 50/60 Hz ndipo amadalira thiransifoma wamba wamba kuti atsitse mphamvu yamagetsi ndikupereka mphamvu zamagetsi. Chifukwa cha kutsika kwafupipafupi, thiransifoma ndi yaikulu kwambiri ndipo imawonongeka kwambiri ndi maginito ndi mkuwa. M'mafakitale othandiza, mphamvu zonse zosinthira mphamvu zimakhala pakati pa 50% ndi 60%.

Izi zikutanthauza kuti pafupifupi theka la mphamvu zamagetsi zomwe zimatengedwa kuchokera ku gululi zimatayika ngati kutentha m'malo mosinthidwa kukhala mphamvu zowotcherera. Ngakhale kutayika kumeneku sikungawonekere kukhala kofunikira pakanthawi kochepa-kumagwira ntchito kwakanthawi kochepa, kumakhala kofunikira pazachuma m'malo opanga mosalekeza.

Ubwino Wapakatikati Wowotcherera Makina Opangira Makina

Makina owotcherera apakati pafupipafupi amagwiritsa ntchito ukadaulo wa inverter womwe umagwira ntchito pamwamba pa 1,000 Hz. Mphamvu ya AC yomwe ikubwera imakonzedwanso kukhala DC kenako imasinthidwa kudzera pa thiransifoma yapakatikati isanaperekedwe ku maelekitirodi. Kuthamanga kwapamwamba kwambiri kumachepetsa kukula kwa thiransifoma ndi kutayika kwa maginito, kuwongolera magwiridwe antchito mpaka pafupifupi 85% -95%.

Kuchokera pamalingaliro auinjiniya, ma frequency apamwamba amathandizira kutembenuka kwa ma elekitiromu ndikuwonjezera liwiro loyankhira. Zotsatira zake, pansi pa zofunikira zowotcherera zofanana, makina owotcherera pafupipafupi amafunikira mphamvu zochepa kuti akwaniritse mtundu womwewo. Ubwino wa kamangidwe kake ndi chifukwa chachikulu chomwe chimachititsa kuti magetsi-akonde makina owotcherera pamalo abwino kwambiri popanga{3}}mphamvu zambiri.

Kuchita bwino kwa mphamvu sikudziwika ndi kutembenuka mtima kokha. Nthawi yowotcherera ndikusintha kwina kofunikira pakuwerengera mphamvu yamakina owotcherera.

Makina a AC nthawi zambiri amafunikira nthawi yayitali yowotcherera chifukwa nthawi yokwera pano ndiyocheperako komanso kukhazikika kwa mafunde kumachepa. Mwachitsanzo, powotcherera chitsulo chofewa cha 1.0 mm, nthawi yowotcherera nthawi zambiri imakhala pakati pa masekondi 0,5 ndi 0.6 kuti muwonetsetse kupanga nugget yoyenera.

Makina owotcherera apakati pafupipafupi amatha kutulutsa nthawi yayitali nthawi yomweyo ndikusunga zotuluka zokhazikika. Nthawi yowotcherera imachepetsedwa kukhala masekondi 0.2-0.3 pansi pa zinthu zomwezo. Kuchepetsa kumeneku sikumangowonjezera kuchuluka kwa kupanga komanso kumachepetsa kugwiritsa ntchito mphamvu pa weld.

Pakuyesa kwenikweni kopanga pansi pa magawo ofanana:

• Kugwiritsa ntchito mphamvu zamakina a AC pa weldmphamvu: pafupifupi 0.018 kWh
• Makina ogwiritsira ntchito mphamvu zamakina pafupipafupi pa weldmphamvu: pafupifupi 0.008 kWh

Ngati mzere wopanga umapanga ma welds 2,000 patsiku, makina a AC amawononga pafupifupi 36 kWh tsiku lililonse, pomwe ma frequency apakati amadya pafupifupi 16 kWh. Kusiyana kwa tsiku ndi tsiku kwa 20 kWh kumachulukana mofulumira. Kungotengera masiku ogwirira ntchito 250 pachaka, kusiyana kwapachaka kumafika pafupifupi 5,000 kWh.

Mukawunika kuchuluka kwa magetsi omwe makina owotcherera amagwiritsira ntchito, pa-data ya weld energy ndi imodzi mwama metric ofunikira kufunsidwa kuchokera kwa ogulitsa.

Poyerekeza ma frequency apakati ndi makina owotcherera a AC, makampani ambiri amangowerengera mphamvu yogwiritsira ntchito mphamvu ndikunyalanyaza mphamvu yamagetsi.

Makina owotchera mawanga a AC nthawi zambiri amatulutsa kuchuluka kwamphamvu kwakanthawi koyambira, komwe kumakhala ndi mphamvu yapakati pa 0,6 ndi 0,8. Kuti akwaniritse zofunikira, opanga nthawi zambiri amayika zida zowonjezera zolipirira mphamvu zamagetsi. M'madera ena, mphamvu zochepa zimatha kubweretsa zilango zandalama kapena kukonzanso kovomerezeka kwamagetsi.

Makina owotcherera apakati pafupipafupi, chifukwa cha mawonekedwe awo okonzedwanso a DC, nthawi zambiri amagwira ntchito ndi mphamvu pafupifupi 1.0. Amapanga kupsinjika kochepa pa gridi yamagetsi ndikusunga mikhalidwe yokhazikika yamagetsi. Kwa malo omwe amagwiritsa ntchito makina owotcherera angapo nthawi imodzi, mwayi wokhazikikawu umachepetsa kutayika kwa mphamvu zokha komanso ndalama zogwirira ntchito.

Choncho, -zaka zisanu zilizonse kuyerekeza mtengo wa makina owotcherera mabala kuyenera kuphatikizirapo kugwira ntchito kwa mphamvu monga gawo la chitsanzo chowunika.

Kuti mupereke chiŵerengero chotheka cha ndalama-zaka zisanu zopulumutsa magetsi, lingalirani izi:

Zongoganizira:

• Mphamvu ya makina: 100 kVA
• Masiku ogwira ntchito pachaka: 250
• Chiwerengero cha weld tsiku lililonse: 2,000 welds
• Mtengo wamagetsi aku mafakitale: $0.14 pa kWh (chitsanzo chamtengo; sinthani ndi dera)

Kutengera pafupifupi-za data ya weld energy:

• Makina owotcherera a AC amawononga pafupifupi 9,000 kWh pachaka, zomwe zimapangitsa kuti pakhale mtengo wamagetsi wapachaka pafupifupi $1,260.
• Makina owotcherera apakati pafupipafupi amawononga pafupifupi 4,000 kWh pachaka, zomwe zimapangitsa kuti pakhale mtengo wamagetsi wapachaka pafupifupi $560.
• Kusungirako pachaka pamakina: pafupifupi $700.
• Zosunga-zaka zisanu pamakina aliwonse: pafupifupi $3,500.

Pamalo ogwiritsira ntchito makina 10, -zazaka zisanu zosungira magetsi zitha kupitirira $35,000. Zinthu zina zikaphatikizidwa-monga kuchepetsedwa kwa ma elekitirodi avale, kusinthasintha kwa weld, kutsika kwa ntchito, kuchulukitsidwa kwa liwiro la kupanga, ndi kutsika kwandalama kwa zida zamagetsi-ubwino wonse wazachuma umakhala wokulirapo.

M'mafakitale monga zida zamagalimoto, malo otsekera mabatire, ndi malo osungira mphamvu zosungirako mphamvu, pomwe mawotchi amakhala okwera, kusiyana kwamitengo kumawonekera kwambiri.

Kuchokera pamalingaliro obweza ndalama, makina owotcherera apakati pafupipafupi amakhala opindulitsa kwambiri pazotsatira izi:

• Voliyumu ya weld pachaka imaposa ma welds 300,000.
• Kupanga kumagwira ntchito masinthidwe angapo kapena ndandanda mosalekeza.
• Zida ndi monga-zitsulo zolimba kwambiri, zotentha-zopangidwa ndi chitsulo, kapena mapepala okutidwa.
• Kusasinthika kwa weld ndi kulondola kwaposachedwa ndizofunikira kwambiri.
• Makina angapo amagwira ntchito nthawi imodzi mkati mwamagetsi omwewo.

Pazinthu zotsika-zokonza pafupipafupi kapena-zokambirana zazing'ono, makina a AC atha kukupatsanibe mtengo wotsikirapo. Komabe, m'malo-akutulutsa mphamvu zambiri, kupulumutsa mphamvu kwa makina owotcherera apakati pafupipafupi kumathetsa kusiyana kwamitengo pakadutsa zaka ziwiri kapena zitatu.

Mapeto

Kusiyana pakati pa ma frequency apakati ndi makina owotcherera ma spot a AC siukadaulo chabe-ndi zachuma. Kusinthasintha kwamphamvu kwamphamvu, nthawi yaifupi yowotcherera, kuwongolera mphamvu zamagetsi, ndi kutayika kwapang'onopang'ono kwapang'onopang'ono kumasulira mwachindunji kutsika kwamitengo yamagetsi pakapita nthawi.

Kwa opanga omwe amawunika zida zatsopano, chofunikira ndikufunsa zoyezeka m'malo mongodalira zomwe zidanenedwa. Musanapange chisankho chogula, funsani ogulitsa:

• Zotsimikizika pa-data yogwiritsa ntchito mphamvu zowotcherera
• Kugwiritsa ntchito mphamvu kumapindika mosiyanasiyana makulidwe azinthu
• Malipoti a mayeso a Power factor
• Kutengera zaka{{0}zaka zisanu zongotengera kuchuluka kwa zinthu zomwe mwapanga

Makina owotchera malo si ndalama chabe; ndi ndalama zoyendetsera-nthawi yayitali. Zikawunikiridwa pakadutsa zaka-zaka zisanu, mphamvu zogwiritsira ntchito mphamvu zimatha kukhudza kwambiri phindu lonse.
