Wɔ mfiridwuma mu nneɛma a wɔyɛ mu no, ahoɔden ho ka yɛ adwumayɛbea no adwumayɛ ho ka fã titiriw. Esiane sɛ nneɛma a wɔyɛ no ahwehwɛde a ɛkɔ soro wɔ nnwinnade a ɛyɛ adwuma yiye na ɛmma ahoɔden pii-kora so nti, .medium frequency spot welding mfiri a wɔde yɛ nneɛmaabɛyɛ nea nkurɔfo ani gye ho a wɔpaw esiane wɔn ahoɔden-sika a wɔkora so mfaso a ɛyɛ nwonwa nti. Enti, ɔkwan bɛn so na mfiri a wɔde yɛ medium frequency spot welding no nya anyinam ahoɔden a wɔkora so? Nnyinasosɛm bɛn na ɛwɔ eyi akyi? Saa asɛm yi bɛma adwumayɛfo mmuae a ɛtwe adwene si nsɛmmisa yi so.
I. Inverter Technology: Ahoɔden a Wɔsakra no Yiye
Mfiridwuma a wɔde sie ahoɔden titiriw-a ɛwɔ medium frequency spot welding mfiri mu no da wɔn inverter nhyehyɛe a wɔagye atom no mu. Amanneɛ kwan so tumi frequency spot welding mfiri de 50Hz alternating current di dwuma tẽẽ, bere a medium frequency spot welding mfiri dan tumi frequency current kɔ medium frequency current bɛyɛ 1000Hz denam inverter so. Ɛnyɛ sɛ saa adeyɛ yi ma anyinam ahoɔden a wɔde di dwuma yiye no tu mpɔn nko na mmom ɛtew transformer a wɔhwere so nso. Sɛ nhwɛso no, transformer volume a ɛwɔ medium frequency spot welding machine mu no yɛ 40% pɛ wɔ power frequency mfiri de no mu, na core material a ɛso tew no ma ahoɔden a wɔde fa kwan so no yɛ tẽẽ na nneɛma a wɔhwere no sua.
II. Abiɛsa-Fase Balanced Input: Grid Adesoa a Wɔtew So
Medium frequency spot welding mfiri fa abiɛsa-phase tumi input, yɛ DC voltage a ɛyɛ den (sɛ nhwɛso no, 500V) denam rectification ne filtering so. Sɛ wɔde toto single-phase input a ɛwɔ power frequency spot welding mfiri mu ho a, abiɛsa-phase balanced input no betumi atew nkɛntɛnso a grid nsakrae nya wɔ welding quality so no so yiye bere a ɛtew reactive power loss so. Saa nhyehyeɛ yi ma ahoɔden a ɛwɔ medium frequency spot welding mfiri mu no tumi yɛ kɛseɛ te sɛ 90%, ɛboro power frequency mfiri dodoɔ so koraa, na ɛnam so ma ahoɔden a wɔde di dwuma no so tew kɛseɛ.
III. DC Output ne Closed-Loop Control: Ahoɔden a Wɔde Di Dwuma Pɛpɛɛpɛ
Nea efi medium frequency spot welding mfiri mu ba no yɛ direct current, a mprempren zero-crossing phenomenon biara nni mu, a ɛde ɔhyew a ɛyɛ den na ɛyɛ den ba, na ɛma welding adwumayɛ tu mpɔn kɛse. Bio nso, ne closed-loop control system no tumi hwɛ welding parameters (te sɛ mprempren, bere) wɔ real-bere mu, dynamically adjusting energy output na akwati ahoɔden a wɔde di dwuma dodo. Sɛ nhwɛso no, HAIFEI medium frequency control system no hwɛ hu sɛ ahoɔden yɛ adwuma pɛpɛɛpɛ wɔ adwuma no so denam current ne constant voltage modes so, na ɛtew nneɛma a wɔsɛe no so.
IV. Data a Wɔasusuw no Hwɛ sɛ Ahoɔden-Sɛkorae Nsunsuanso
Sɛnea nnwuma mu nsɛm a wɔasusuw kyerɛ no, ahoɔden a wɔde di dwuma wɔ medium frequency spot welding mfiri mu no yɛ 60%-70% pɛ wɔ power frequency spot welding mfiri mu de no mu, na ɛma ahoɔden-korabea nkɛntɛnso bɛboro 30%. Saa mfasoɔ yi ho hia titire wɔ bere tenten-yɛyɛ a ɛkɔ so yɛ mu, titire ɛfata ma tebea horow a wɔde ahoɔden di dwuma kɛse te sɛ kar a wɔyɛ ne ɛlɛtrɔnik nhyiam. Sɛ nhwɛso no, sɛ wɔreyɛ aluminum nneɛma anaa dade mprɛte a wɔde galvanized ayɛ no welding a, ɔhyew a ɛyɛ adwuma yiye wɔ medium frequency spot welding mfiri ahorow mu no yɛ kɛse, na ɛtew ahoɔden ho ka a wɔbɔ wɔ ade biako biara ho no so bio.
Awie
Sɛ yɛbɛbɔ no mua a, ahoɔden-koraeɛ mfasoɔ a ɛwɔmedium frequency spot welding mfiri a wɔde yɛ nneɛmafi synergistic nsunsuanso a wɔn inverter mfiridwuma, abiɛsa-phase balanced input, DC output, ne nyansa control nhyehyɛe. Ɛdenam ahoɔden a wɔhwere so tew, grid adesoa a wɔma ɛyɛ papa, ne welding parameters a wɔhwɛ so pɛpɛɛpɛ so no, medium frequency spot welding mfiri ahorow no di bɔhyɛ a ɛne sɛ "wɔbɛkora anyinam ahoɔden so 30% so" no so ampa. Wɔ nnwumakuw a wɔredi nneɛma a wɔyɛ no yiye ne nkɔso a ɛtra hɔ daa akyi fam no, ɛnyɛ mfiridwuma mu nkɔso a wɔda no adi nko na sɛ wɔpaw mfiri a wɔde yɛ nneɛma a ɛwɔ baabi a ɛyɛ adwuma yiye na mmom ɛyɛ anammɔn titiriw a wɔde bɛtew adwumayɛ ho ka so na wɔama akansi akɔ anim.
