1.Descript
Electrochemical polishing inzira inobvisa microscopic protrusions kubva pamusoro pesimbi ne electrochemical dissolution, zvichiita kuti pave nechiso chakatsetseka uye chakafanana. Munzvimbo dzemuchadenga neminda yezvokurapa, zvinoumba zvinoda yakanyanya kukwirira pamusoro pemhando, corrosion resistance, uye biocompatibility, zvichiita kuti electrochemical polishing imwe yeakakosha maitiro. Echinyakare DC magetsi emagetsi anotarisana nematambudziko akadai sekushomeka uye kusafanana kwakashata mukupukuta kwemagetsi, nepo yakakwirira-frequency switch DC magetsi emagetsi uye pulse magetsi anosimudzira zvakanyanya danho rekuita kwe electrochemical polishing.
2.Kushanda Misimboti yeHigh-Frequency Switch DC uye Pulse Power Supplies
2.1 High-Frequency Switch DC Power Supply A high-frequency switch DC power supply inoshandura utility frequency AC kuenda kuhigh-frequency AC, yozoigadzirisa nekuipepeta kuti ipe simba rakagadzikana reDC. Iyo yekushanda frequency inowanzobva pamakumi e kilohertz kusvika kumazana akati wandei kilohertz, ine zvinotevera maficha:
Kubudirira Kwepamusoro: Shanduko yekushandura inogona kudarika 90%, zvichikonzera kuderera kwesimba rekushandisa.
High Precision: Yakagadzikana inobuda ikozvino uye voltage ine shanduko isingasviki ± 1%.
Kurumidza Kupindura: Kurumidza kusimba mhinduro, yakakodzera kune yakaoma maitiro zvinodiwa.
2.2 Pulse Power Supply A pulse power supply yakavakirwa pahigh-frequency switch power supply tekinoroji uye inobuda periodic pulse currents kuburikidza nedhiraivha yekudzora. Zvimiro zvinosanganisira:
Inogadziriswa Pulse Waveform: Inotsigira square mafungu uye DC.
High Flexibility: Pulse frequency, duty cycle, uye amplitude inogona kuzvimiririra kugadziriswa.
Kuvandudzwa Kwekupenya Mhedzisiro: Iyo inopindirana yemhando yekupuruzira inoderedza electrolyte polarization uye inovandudza kupenya kufanana.
3.Hunhu hweElectrochemical Polishing Power Supplies yeAerospace uye Medical Fields
Magetsi anoshandiswa mu electrochemical polishing for aerospace uye zvekurapa zvikumbiro zvinofanirwa kusangana nemhando yepamusoro yemhando yechigadzirwa, chengetedzo, uye kuvimbika. Naizvozvo, ivo vanofanirwa kuve neanotevera maitiro:
3.1 High Precision Control
● Ikozvino uye Voltage Kugadzikana: Electrochemical polishing yeaerospace uye zvikamu zvezvokurapa zvinoda zvakanyanya kukwirira kwepamusoro, saka magetsi anofanira kupa zvakanyanya kugadzikana ikozvino uye magetsi, nekushanduka-shanduka kunowanzodzorwa mukati ± 1%.
● Adjustable Parameters: Simba remagetsi rinofanira kutsigira kunyatsogadziriswa kwezvino density, voltage, uye polishing nguva yekusangana nezvinodiwa zvezvinhu zvakasiyana-siyana uye maitiro.
● Constant Current / Constant Voltage Mode: Inotsigira nguva dzose ikozvino (CC) uye nguva dzose voltage (CV) modes kuti iwane matanho akasiyana ekugadzirisa.
3.2 Kuvimbika kwepamusoro
● Hupenyu Hwakareba Hwebasa: Nzvimbo yekugadzira munzvimbo yeaerospace uye yezvokurapa inoda kuvimbika kwemidziyo yepamusoro, saka magetsi anofanirwa kugadzirwa nemhando yepamusoro-soro uye magadzirirwo epamusoro kuti ave nechokwadi chekushanda kwakagadzikana kwenguva refu.
● Kudzivirirwa Kwemhosva: Zvimiro zvakadai se overcurrent, overvoltage, overheating, uye pfupi-circuit kudzivirirwa kudzivirira kukanganisa kune workpieces kana kugadzirwa kwenjodzi nekuda kwekukundikana kwemagetsi.
●Anti-Kupindira Kugona: Simba remagetsi rinofanira kunge riine simba remagetsi remagetsi (EMI) rinopikisa kudzivirira kukanganisa kune zvakakosha zvezvokurapa kana aerospace zvigadzirwa zvemagetsi.
3.3 Kuchinjika kune Zvinokosha Zvishandiso
● Multi-material Compatibility: Zvishandiso zvakajairika zvinoshandiswa munzvimbo yeaerospace uye yezvokurapa, zvakadai setitanium alloys, simbi isina tsvina, uye nickel-based alloys, inoda kuti magetsi aenderane nemhando dzakasiyana dze electrochemical polishing.
●Low Voltage, High Current Capability: Zvimwe zvinhu (zvakadai setitanium alloys) zvinoda low voltage (5-15 V) uye high current density (20-100 A/dm²) ye electrochemical polishing, saka magetsi anofanirwa kuve neanoenderana nekubuda.
4.Technology Development Trends
4.1 Yepamusoro Frequency uye Precision Remangwana magadzirirwo emagetsi e-high-frequency switch uye pulse magetsi anozotarisa pama frequency epamusoro uye nemazvo epamusoro kuzadzisa kudiwa kwe-ultra-chaiyo yepamusoro kurapwa munzvimbo yeaerospace uye yekurapa.
4.2 Kudzora Hungwaru Kubatanidzwa kwehunyanzvi hwekugadzira (AI) uye Internet yeZvinhu (IoT) matekinoroji anozogonesa kutonga kwakangwara uye chaiyo-nguva yekutarisa kwe electrochemical polishing maitiro, kuvandudza kugadzirwa kwakanaka uye kunaka kwechigadzirwa.
4.3 Environmental Sustainability Kuvandudzwa kwesimba rakaderera, rakaderera-kusvibiswa kwemagetsi ekupa tekinoroji kuderedza kukanganiswa kwezvakatipoteredza kwe electrochemical polishing maitiro, kuenderana neyakasvibira yekugadzira maitiro.
5. Mhedziso
High-frequency switch DC magetsi emagetsi uye pulse power emagetsi, nekushanda kwawo kwepamusoro, nemazvo, uye kukurumidza kupindura maitiro, anoita basa rakakosha mukuporiswa kwemagetsi emuchadenga neminda yekurapa. Ivo havangonatsiridza chete kunaka uye kugona kwekurapa kwepamusoro asiwo vanosangana nezvinodiwa zvakasimba zvekuvimbika uye kuenderana mumaindasitiri aya. Nekuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji, high-frequency switch uye pulse simba rekupa zvinovhura zvakatonyanya kugona mukupenya kweelectrochemical polishing, kusimudzira maindasitiri emuchadenga uye ezvokurapa kusvika padanho repamusoro rebudiriro.
