ʻO nā hiʻohiʻona wili kumu ʻelua o nā mea hoʻoheheʻe hoʻoheheʻe Capacitive

Hoʻolauna

I ka makahiki 2023, ua hoʻohana kekahi ʻoihana pākaukau mana alakaʻi i ka ʻelima-hanaunacapacitive hoʻokuʻu wahi welder, e ho'ēmi ana i ka pākuʻi pāpaʻi pāpaʻi pāpaʻi mai 3.2% a i 0.05% a me ka mālama ʻana ma luna o 500,000 yuan i kēlā me kēia makahiki no kēlā me kēia hāmeʻa i nā kumukūʻai lole electrode. I ke kuʻiʻana o kekahi 'ano o ka rocket wahie pahu i loko o ka aerospace kahua, kacapacitive hoʻokuʻu wahi welder, me kona 0.1ms-ka pae hoʻokuʻu ikehu pololei, hoʻonui i ka ikaika weld e 42%. Ma hope o kēia mau mea hoʻokō i loaʻa i ka -hohonu o nā hiʻohiʻona wiliwili kumu ʻelua o kacapacitive hoʻokuʻu wahi welder: ʻenehana hoʻokuʻu pulse capacitoradynamic impedance compensation system. ʻO kēia ʻatikala, ma o ka hoʻohālikelike ʻenehana a me nā loiloi hihia kūpono, e hōʻike ana i ke ʻano o kēia mau hiʻohiʻona ʻelua i ka hoʻomaikaʻi ʻana i ka hana pololei.

I. ʻenehana hoʻoheheʻe ʻana i ka puʻupuʻu Capacitor: ʻO kahi holomua ʻoihana i loko o ka Milisecond{1}}Level Control Energy

1. ʻElua-Kauoha-o-Magnitude Improvement in Energy Release Accuracy

ʻO ka pono kumu o kacapacitive hoʻokuʻu wahi welderAia i loko o kāna ʻōnaehana hoʻoiho a me ka hoʻokuʻu ʻana i ka capacitor, kahi e loaʻa ai kahi lele qualitative i ka mana o ka ikehu i hoʻohālikelike ʻia me nā lako kuʻi kuʻuna kuʻuna:

Ke kumu hoʻokō ʻenehana:

• Huina manaʻo hikiwawe: E=0.5×C×V²
• (C=waiwai kaha, V=voli uila)
• Ma o ka - ʻōnaehana hoʻopololei kiʻekiʻe (± 0.5V hewa) a me kahi module hoʻololi wikiwiki IGBT, ʻike ʻia ka hewa o kēlā me kēia hoʻokuʻu ʻana.<±1%.

2. Microsecond{1}}Level Waveform Regulation Capability

• ʻO kacapacitive hoʻokuʻu wahi welderKākoʻo ia i ka hoʻonohonoho ʻana i ka nalu hoʻokuʻu paʻakikī, e ʻae i nā pihi hoʻokuʻu ikehu maʻamau no nā waiwai waiwai like ʻole:
• ʻEkolu-ʻano nalu hoʻokuʻu:
• Mamua -pae hoʻokuʻu (0.5ms): Hoʻopau i ka pale ʻana
• ʻO ke kahua hoʻokuʻu nui (2-8ms): Form weld nugget
• ʻĀpana hoʻoheheʻe (1ms): Hoʻomaikaʻi i ka microstructure
• Ka hihia noi maʻamau:
• I ka wiliwili ʻana o kahi ʻoihana lāʻau lapaʻau i nā ʻāpana lahilahi 0.1mm titanium alloy, ua hoʻohana ʻo ia i ke ʻano "pālua-peak pulse" (pulse nui + hoʻonui ikehu lua), e hoʻonui ana i ka ikaika weld tensile mai 320MPa a i 450MPa-a hiki i 95% o ka ikaika kumu.

II. Dynamic Impedance Compensation System: He Adaptive Revolution no nā Kūlana Hana Paʻakikī

1. ʻOiaʻiʻo-Ka nānā ʻana i ka manawa a me ka mīkini uku

ʻO kacapacitive hoʻokuʻu wahi welderua lako me kahi ʻōnaehana ʻike akamai e hiki ai i ka millisecond-level dynamic adjustment during the welded process:

Ke kumu o ka algorithm uku:

• Waiwai pānaʻi uila uila ΔV=K×(R_actual - R_base)/R_base×V_set
• (K=coefficient mea, R_actual=real-impedance manawa, R_base=reference value)
• Hiki i kēia algorithm ke hoʻomalu i ka loli o ka ikehu i ka wā o ka hoʻoheheʻe metala like ʻole i loko o ± 2%.

2. Hoʻohana ma nā ʻano ʻano maʻamau ʻehā

• Ka uku no ka hoʻololi koke ʻana i ka mānoanoa mea:
• I ke kuʻi ʻana o nā modules pākahiko kaʻa hou, ʻike koke ka ʻōnaehana i ka ʻokoʻa mānoanoa ma waena o 0.3mm copper foil a me 2mm steel shell, e hoʻonui ana i ke kaomi electrode mai 200N a i 850N e hōʻoia i ka hohonu o ka weld nugget.
• Hoʻololi i ka hoʻohaumia ʻana i ka ʻili:
• I ka wā i wiliwili ai kekahi ʻoihana 3C i nā pahu nickel-plated, ua ʻike ka ʻōnaehana i kahi ʻāpana oxide 0.05mm a hoʻonui ʻakomi i ka ikehu hoʻokuʻu ʻana ma 12%, e hoʻonui ana i ka helu hua mai 82% a i 99.5%.
• Hoʻoponopono no ka neʻe ʻana o ka mahana:
• Ke hoʻomau nei ka hana ʻana o nā mea hana i ka piʻi ʻana o ka wela o ka capacitor i 45 degere, e hoʻemi ka ʻōnaehana i ka puʻu uila e ka coefficient o 0.5V/degere e mālama ai i ke kūpaʻa o ka puka makani.
• Ka uku no ka lole electrode:
• Ua hoʻokumu ʻia kahi kumu hoʻohālike makemakika ma waena o ka lole anawaena electrode a me ka uku kaomi:
• P_comp=P0×(D0/D_current)^1.5
• (D0=anawaena electrode hou, D_ke anawaena=o keia manawa)
• Ma hope o ka hoʻohana ʻana o kahi ʻoihana aerospace i kēia kumu hoʻohālike, ua hoʻonui ʻia ke ola lawelawe electrode mai 8,000 mau wahi a i 25,000 mau kiko.

III. Technical Synergy Effect: Industrial Value Creation of 1+1>2

1. ʻO ka hui gula no ka hana pololei

I ka hoʻoheheʻe ʻia ʻana o ka pahu pahu mana:

• Hoʻomaopopo ka ʻenehana Pulse Capacitor i hoʻokahi -hewa i ka ikehu kiko<±1%
• Hoʻopau ʻo Dynamic compensation system i ka hopena o nā loli o ka mānoanoa
• Ka hopena holoʻokoʻa: Ua hoʻemi ʻia ka nui o ka welding spatter mai 5% a i 0.08%, hoʻonui ʻia ka hana hana e 30%.

2. Hoʻopaʻa Paʻa ʻelua no ka Mana Kūʻai

ʻO ka hihia kūpono o kahi hale hana kaʻa ikehu hou:

• Ma o ka hoʻonui ʻana o nā ʻenehana ʻelua, ke kumukūʻai piha makahiki o ka hoʻokahicapacitive hoʻokuʻu wahi welderua hoemiia mai ka 280,000 yuan a i ka 95,000 yuan, a ua hoopokoleia ka manawa uku hou i 14 mahina.

Ka hopena

Ma hope o ka hoʻokomo ʻana o kahi ʻoihana hana satellite i kacapacitive hoʻokuʻu wahi welderme kēia mau hiʻohiʻona ʻelua, ua lele ka helu kuʻi ʻana o nā pipeline wahie mai 76% a i 99.9%, a ua hala i ka palapala hōʻoia maʻamau o NASA SPE-3000. Hōʻike ka ʻikepili i ka hui pū ʻana o ka ʻenehana hoʻokuʻu capacitor pulse a me ka ʻōnaehana uku impedance ikaika e hiki ai i kacapacitive hoʻokuʻu wahi weldere hoʻokō i nā holomua holoʻokoʻa ma nā ʻano ʻekolu: ka pololei, ka hoʻololi ʻana i ke kūlana hana, a me nā pono waiwai. Me ka hoʻohui pū ʻana o ka ʻenehana ʻike maka a me ka ʻenehana ʻike mīkini, e ʻike ana ka mea welder capacitive discharge spot welder e hiki mai ana i kahi puʻupuʻu paʻa naʻauao o ka "parameter self-aʻo - defect self-repair - process self-optimization", e hoʻohuli ana i ka hana kiʻekiʻe i loko o kahi au hou o ka nanoscale.

Hoʻokaʻaʻike i kēia manawa
