Isimiso somshini wokushisela ukushisa kwe-pulse: Indlela yokushisisa ye-pulse power supply isebenzisa ukushisa kwe-Joule okukhiqizwa lapho i-pulse current igeleza ngezinto ezimelana kakhulu ne-molybdenum ne-titanium ukushisa i-welding.Ngokuvamile, ukuhlangana okushisayo kuxhunywe ekugcineni kwembobo yokushisa, futhi amandla kagesi asheshayo akhiqizwa kusukela kule mpendulo alawula ukunikezwa kwamandla ukuze kuqinisekiswe ukunemba kwezinga lokushisa elimisiwe.
Isici esibucayi kakhulu somshini wokushisela ukushisa kwe-pulse: Ukunemba kokulawula izinga lokushisa kwekhanda le-welding (ukunemba kwesethi yokushisa kwekhanda le-welding) Izinto ezithinta ukunemba kokulawula izinga lokushisa: Ukunemba kokulawula kwamanje kokushisa + isivinini sokushisa kwempendulo ye-thermocouple
Umehluko:
Ukunemba okuhlukile kokulawula kwamanje kokushisisa
Umshini wokushisela wokushisa oguquguqukayo ukhipha umshini wokushisela oqondile, usebenzisa imvamisa ye-inverter ephakeme (4kHz), umjikelezo owodwa ube ama-millisecond angu-0.25, ophindwe izikhathi ezingu-80 ngaphezu kwama-20ms omshini wokushisela we-AC ojwayelekile, okuholela ekunembeni okuthuthukisiwe kokulawula.Inomsebenzi wokunxephezela amandla kagesi wegridi, futhi ayithinteki kangako ukushintshashintsha kwamandla kagesi.Ngakolunye uhlangothi, umshini wokushisela ukushisa kwe-pulse ojwayelekile usebenza imvamisa engu-50Hz yegridi AC, umjikelezo owodwa ube ama-millisecond angama-20.Ithintwa kakhulu ama-voltage egridi angazinzile futhi ayikwazi ukulawula okwamanje kahle kakhulu.
Izivinini ezihlukene zezinga lokushisa lempendulo ye-thermocouple (isivinini sesampula)
Umshini wokushisela ukushisa kwe-pulse oguquguqukayo uqeda lokhu phakathi kwe-millisecond engu-1, kuyilapho umshini wokushisela ukushisa kwe-pulse ovamile ngokuvamile uthatha amashumi ama-millisecond noma ngaphezulu, okuholela kumehluko obonakalayo wejubane lesampula phakathi kokubili.
Amazinga we-welding ahlukile
Izinga lokushisela elibonakalayo lomshini wokushisela wokushisa we-pulse liphakeme kunelo lomshini wokushisela wokushisa we-pulse ojwayelekile.
Izikhathi zokuphila zekhanda lokushisela ezihlukene
Umshini wokushisela ukushisa okuguquguqukayo kwe-pulse unokulahlekelwa okuphansi esikhathini sokuphila kwekhanda lokushisela kanye nempilo ende, kuyilapho umshini wokushisela ukushisa kwe-pulse ovamile unomphumela ophambene nokulahlekelwa okukhulu kanye nokuphila okufushane.
Ukunemba kokulawula izinga lokushisa okuhlukile
Ukunemba kokulawula izinga lokushisa komshini wokushisela ukushisa okuguquguqukayo kwe-pulse cishe ku-±3%, kanti ukunemba kokulawula izinga lokushisa komshini wokushisela ukushisa kwe-pulse okuvamile kunokuphambuka okukhulu.
Kafushane, umshini wokushisela wokushisa oguquguqukayo unokunemba okuphezulu kokulawula nokuzinza kwezinga lokushisa, amanani aphansi we-welding abonakalayo, ubude bekhanda lokushisela amakhanda amade, kanye nokusebenza kahle okuphezulu uma kuqhathaniswa nemishini yokushisela ukushisa kwe-pulse evamile.Ngakho-ke, inokusebenza okuphezulu ngokuphelele.
