Mfundo zikugwira ntchito ya inverter ndi kuwotcherera: kufotokoza, madera ndiponso zipangizo

kuwotcherera makina Traditional ndi tiransifoma chomwecho yaikulu pang'onopang'ono kuchepa mphamvu. M'malo mwake, tsopano pali yaying'ono kuwotcherera inverters. Iwo yosavuta kugwiritsa ntchito, iwo akhoza kugwiritsidwa ntchito kuyamba. Pofuna kupeza mtundu chipangizo, m'pofunika kuganizira kapangidwe ndi mfundo ntchito ya inverter ndi kuwotcherera.

za kamangidwe

chipangizo isiyana ndi tiransifoma chikhalidwe ndi bwino kuti aliyense owotcherera. The inverter zikugwira ntchito panopa njira kutembenuka zimachitika mosiyana. njira izi zimachitika mu magawo ndi thiransifoma ang'ono amene miyeso mapaketi zikuluzikulu pang'ono yafodya. Wina kusiyana - dongosolo amagetsi kulamulira. Iwo amalola kuti atsogolere ndondomeko kuwotcherera. Ndiyamika imelo khalidwe mfundo anapanga dongosolo. Apa mmene makina inverter kuwotcherera. Reviews zida izi mu zosangalatsa. Anthu ambiri amagwiritsira ntchito chifukwa cha kamangidwe yaying'ono ndi china chotulutsa khalidwe.

Mfundo wonse wa opareshoni

Poyamba, athandizira mafunde ndi voteji wa volts 220 pa pafupipafupi variable umayenda mwa rectifier ndiyeno n'kukhala zonse ndi. Komanso, masiku ano ankawachotsera mwa fyuluta. Nthawi zambiri ntchito ngati chiwembu miyambo zochokera capacitors electrolytic. Kenako, DC voteji ndipo m'kupita panopa kupyolera michenga yopangira zida zamagetsi modulator, kumene kachiwiri anatembenukira kwa AC, koma ndi mafurikwense apamwamba. Mu zitsanzo osiyana, chithunzi ichi ndi osiyana, koma si upambana 100 kHz. Panopa ndiye kukonzedwa ndi voteji kachiwiri akutsikira mtengo wofunikila zitsulo china chotulutsa. The opaleshoni mfundo inverter kuwotcherera zochokera converters mkulu-pafupipafupi. Pamaso pa zigawo izi zimathandiza ntchito tiransifoma yaing'ono, potero achepetsa wagawo kulemera. Mwachitsanzo, ku makina kuwotcherera inverter wokhoza kupereka panopa wa amperes 160, ndi thiransifoma ayenera kuganizira zosaposa 250 magalamu. thiransifoma adzakhala ndi kulemera osachepera makilogalamu 18 tikwaniritse zotsatira chomwecho ntchito zida wamba. Kungakhale kovuta kwambiri.

Ulamuliro wagawo - ndi mwayi waukulu makina inverter kuwotcherera

A kwambiri pa ntchito zida izi masewero zamagetsi. Chifukwa izo osiyanitsidwa ubwenzi. Izi zimathandiza kuchepetsa bwinobwino Arc, kusintha kapena kulisunga pa mlingo woyenera ngati n'koyenera. Lokhoza makhalidwe kupatuka Arc yomweyo kuwerenga ndi microprocessor lapansi. Chotero mfundo za ntchito ya makina inverter kuwotcherera ndi kukhala amagetsi kulamulira wagawo kupereka magetsi Arc pazipita makhalidwe khola. Izi pamapeto pake kumawonjezera khalidwe la kuwotcherera lapansi.

chojambula chithunzi

Mu rectifier alternating panopa pa pafupipafupi 50 Hz ndi voteji wa volts 220 umadutsa mlatho diode wamphamvu. Ripple panopa ndi kuyamika variable pafupipafupi ankawachotsera kukhalapo mu dera la capacitors electrolytic. Mu kugwira ntchito, diode mlatho umamumvera kutenthedwa, kotero diodes wokwera radiators. Komanso, inverter ali okonzeka ndi lama fuyusi matenthedwe. Iye amayamba ngati diodes anali usavutike madigiri 90. Matenthedwe chimateteza diodes. Pafupi ndi diode mlatho Tingaone mwachilungamo amphamvu capacitors wonse. chawo akhoza osiyanasiyana monga microfarads 140 kwa 800. Komanso mu dera ndi zopezeka Zosefera, amene sadzalola m'kati kusokonezedwa iliyonse. Tafotokoza zimene ali kuwotcherera inverter mfundo. Galimoto chimatha zinthu zina. Tiyeni tione m'munsimu.

Inverter: icho chiri

Mwachindunji inverter lenilenilo wamangidwa pa awiri mosfetah. Mphamvu transistors. Iwo amakonda kutentha kwambiri moti akhale okonzeka ndi Redieta a. Chotero michenga yopangira zida zamagetsi zinthu vuto la kusintha Mafunde kudutsa zimachitika thiransifoma. Zikugwira ntchito mafurikwense pano akhoza upambana zikwi zingapo kHz. Chifukwa cha panopa ili ndi kwaiye ndi pafupipafupi variable. The transistors ayenera kukhala kugonjetsedwa ndi madontho voteji. Opanga akonzekeretse chipangizo ndi madera wapadera zozitetezera. Nthawi zambiri, iwo kudutsa resistors dera ndi capacitors. Ndiye akubwera mu sekondale kumulowetsa sitepe-pansi thiransifoma. voteji wake wamng'ono - 70 volts. Koma panopa akhoza kukhala 130-140 mikuza mawu.

The rectifier linanena bungwe

Kuti apange yothandizira linanena bungwe panopa ndi voteji ntchito linanena bungwe rectifiers odalirika. chiwembu Izi zikuchitika chifukwa cha diodes awiri, omwe cathode wamba. Zinthu zimene zimaonetseratu mkulu-ntchito, nthawi yomweyo kutsegulidwa ndi kutsekedwa msanga. Zimene nthawi ya diodes pafupifupi 50 nanoseconds. liwiro izi ndi zofunika kwambiri. Diodes kugwira ntchito ndi mafunde a pafupipafupi mkulu, zinthu wamba michenga yopangira zida zamagetsi sangathe kulimbana ndi ntchito imeneyi. Iwo alibe zokwanira kusinthitsa liwiro. Mu nkhani ya kukonza, ngakhale kudziwa kuwotcherera inverter chipangizo, mfundo opaleshoni, diodes izi analimbikitsa kusintha kwa nyengo ndi makhalidwe omwewo.

Kulengedwa ndi ntchito dongosolo amagetsi

Izo zoyendetsedwa ndi yang'anira voteji, anaikira 15 volts. Zinthu zimene tatchulazi anaika radiators lapansi. Wonjezerani voteji kwa gulu amachokera kwa rectifier chachikulu. Pamene voteji ndi umagwiritsidwa choyamba capacitors onse mlandu. The voteji pa mphindi ino ikukula. Chitetezo diode msonkhano ntchito kutipanikiza chiwembu ndi resistors mphamvu. Pamene capacitor ndi mlandu kwathunthu, makina kuwotcherera adzayamba ntchito yake. Atseka ojambula kulandirana, ndi resistor sadzaweruzidwa nawo mbali.

zigawo zina ndi machitidwe

Kapangidwe ndi ntchito mfundo inverter ndi kuwotcherera kutanthauza kuli machitidwe ena ndi mbali yomwe ngati ntchito yapamwamba chipangizo. Chotero, inu mukhoza kusankha dongosolo kulamulira, komanso madalaivala. The mbali yaikulu apa ndi PWM Mtsogoleri Chip. Imakhala kulamulira zochita za transistors mphamvu. Komanso, chipangizo ali zosiyanasiyana kulamulira ndi lamulo dera. Pankhaniyi, chinthu chachikulu chimene thiransifoma. M'pofunika kuchepetsa mphamvu ndi makhalidwe ena a apano pambuyo thiransifoma linanena bungwe. zochita kuwotcherera inverter mfundo zimasonyezanso kuti kuli njira yabwino kuyan'anila voteji ndipo panopa makhalidwe a linanena bungwe la kusowa mains. wagawo iyi imakhala ndi ntchito madera mkuzamawu ofotokoza. Cholinga cha dongosolo - kuyamba mwadzidzidzi chitetezo mode vuto la mwadzidzidzi. Amagwiritsidwanso lakonzedwa kuti aziona ntchito ndi Kutukula a pachikhalidwe ndi zamagetsi.

Kuwotcherera makina TIG kuwotcherera ndi argon

zitsulo inert mpweya kuwotcherera - ndi imodzi mwa njira yotchuka kwambiri ya kuwotcherera Buku lero. Ntchito ndi argon amapereka mfundo apamwamba chifukwa kumaliza kudzipatula kusamba. Choncho n'zotheka ntchito ndi zitsulo onse, ngakhale ndi aluminum, magnesium, titaniyamu ndi kasakaniza wazitsulo awo. Mfundo inverter kuwotcherera ndi argon kanthu wapadera kuchokera inverter wamba si wosiyana. Chachikulu kusiyana ndi osati ntchito mphamvu kuwotcherera gwero, komanso burner wapadera mu ndondomekoyi. TIG-kuwotcherera kumafuna Kutentha kwa gawo okhazikika ntchito kudzera mwa Arc magetsi amene analengedwa ndi refractory tungsten elekitirodi. Ambiri chidwi kuona mmene inverter kuwotcherera makina a mtundu uwu. Tiyeni tifufuze.

Yomanga kuwotcherera TIG-chipangizo

An zida chifukwa TIG kuwotcherera ndi gwero panopa ndi burner wapadera. Origin zingamuthandize kupoletsa ndi Arc magetsi, komanso kukhala kuchuluka kwake mu magawo yachibadwa. A nambala yaikulu zitsulo ndi kasakaniza wazitsulo, sipangakhalenso opareshoni bwino, ndi kuchuluka kwa kusintha zikutanthauza. Lero ntchito mayunitsi michenga yopangira zida zamagetsi inverter. Izi inverter kuwotcherera TIG. Mfundo ntchito sasiyana ku inverter ochiritsira, koma linanena bungwe la chotero chipangizo pamodzi. Direct panopa ntchito ntchito ndi zitsulo zosapanga dzimbiri, mkuwa kasakaniza wazitsulo. Amasintha mosiyanasiyana komanso oyenera magnesium, zotayidwa ndi zina kasakaniza wazitsulo ofanana. opareshoni ngati mafunde likukulira ntchito kuwotcherera mbali woonda. Komanso mu dongosolo la burner iwo ali. Ndi chiyani icho? Izi ndi chipangizo apadera kuika tungsten elekitirodi. Iwo ali nozzle imene kotunga argon. Mosiyana ndi miyambo zoopsa zoyenera kuwotcherera, ndi TIG kuwotcherera muuni kwa kotunga mpweya akuyamba pamaso azinyadira Arc. Izi amapewa zitsulo moto.

Pomaliza

mtengo wotsika zida ngati limachititsa kuganizira mozama za pogula makina amenewa kwa banja. Ngati inu kuphunzira momwe molimba ntchito chipangizo yotero, mungathe kupeza. Argon kuwotcherera lero likufuna kwambiri. Inu mukhoza kugula ndi yotchipa zoweta TIG-kuwotcherera inverter 180 m. Mfundo ntchito wagawo izi zimathandiza kuti ntchito mu mode Buku kuwotcherera. Ndi njira konsekonse. mtengo wake ranges ku rubles 13 15 chikwi. Kwambiri wotchipa zitsanzo Chinese lingathe kukopedwa pa mtengo wa 6000 rubles. zipangizo Professional ndalama za zikwi 50 rubles.
