Tubooyinka Vacuum-ka Hore Hordhac Qalabka Soo noqnoqoshada Sare

20 sano ka hor, ilaha tamarta-soo noqnoqda sare (sida badan loo yaqaan "Furnaces-soo noqnoqda sare") loo isticmaalo tuubooyinka alxanka iyo kulaylka ee Shiinaha ayaa inta badan ahaa qalab la tuubooyinka elektarooniga ah (sidoo kale loo yaqaan "tuubooyinka vacuum") sida qaybaha inverter ugu weyn. Mabda'a aasaasiga ah waxaa lagu muujiyay shaxanka soo socda:

AC warshadaha caadiga ah (saddex-waji afar fiilooyin 380V / 50HZ ee Shiinaha) waxaa loo beddelaa AC hagaajin karo laga bilaabo 0 ilaa 380V (soo noqnoqda aan isbeddelin) iyada oo loo marayo thyristor AC korantada regulator, ka dibna kor u kacay ilaa ku dhawaad 10000V danab sare (soo noqnoqda aan isbeddelin) by a koronto ah, ka dibna koronto hagaajinaysaa kun koronto by DC Oscilated by tube vacuum ilaa HF iyo HV hadda, ka dibna iyada oo loo marayo resonance barbar LC si ay u xoojiyaan oscillating hadda, iyo ka dib dhimista danab sahayda inductor loo isticmaalo kululaynta ee tuubooyinka birta iyo workpieces kale iwm.

Ujeeddada xeerka korantada AC waa in la hagaajiyo gelinta iyo awoodda wax-soo-saarka si loo buuxiyo shuruudaha shaqada, iyo marka korantada la hagaajiyo sidoo kale waxay u baahan tahay inay ka dhigto korantada mid deggan si loo hubiyo xasilloonida soosaarka qalabka ee xaaladaha hawlgalka qaarkood.

Sababo la xiriira isticmaalka tube vacuum (voltka sare qaybaha yar yar hadda), voltaji waa in la kordhiyo ama ma soo saari karaan awood weyn, laakiin waqti isku mid ah, si ay ula qabsadaan caqabada yar ee inductor ah, waxaa lagama maarmaan ah in la sii yareeyo danab.

Sawirada hoose waa 600KW hal-loop vacuum tube oo soo noqnoqota iyo 100KW oo saddex geesood ah vacuum tube HF qalabka deminta.

In warshadaha alxanka tuubooyinka, weli waxaa jira tiro yar oo ah tuubooyinka vacuum inta jeer ee soo noqnoqda, halka in beeraha sida deminta iyo brazing, tuubooyinka vacuum inta jeer sare ayaa weli si ballaaran loo isticmaalo.
