Take you to understand the fully automatic temperature closed loop intermediate frequency isithando sokushisa sangaphakathi

The 750KW/1.0KHZ intermediate frequency induction heating furnace adopts three automatic selection mechanisms of feeding, feeding, discharging and temperature. The specially proposed temperature closed-loop control uses two power supplies and three sensors. The thermometer adopts perforated temperature measurement, the first thermometer is in the preheating section, and the second thermometer is at a certain position away from the furnace outlet. The first thermometer collects the temperature of the specific temperature measurement point and feeds it back to the PLC. The PLC intelligent output ensures that the temperature of the furnace outlet meets the set temperature. Two thermometers, two power supplies, multiple sensors, modular design It constitutes a fully closed-loop temperature control system.

Imingcele yenqubo eyinhloko yesithando sokushisa esiphakathi kwe-frequency induction imi kanje:

1. Izinto ezingenalutho: 45 # insimbi, njll.

2. Ububanzi bemininingwane engenalutho: ububanzi Φ70-160, ubude 120-540. Amabha amaningi anikezwa ngokuzenzakalelayo uhlobo lwebhodi lokuwasha, futhi lawo adlula ububanzi bomshini wokuphakelayo noma afakwa endaweni eyi-V ngokuzenzela.

3. Izinga lokushisa: 1250℃.

4. Ibhithi: Okujwayelekile akunalutho Φ120, ubude 250mm: 44 imizuzwana/ucezu. Ububanzi Φ90 nobude 400mm: 40 imizuzwana/izingcezu. Ububanzi Φ150 nobude 300mm: 82 imizuzwana/ucezu.

5. Ukushisa kuzinzile ngesikhathi sokusebenza okujwayelekile, futhi ukushintshashintsha kwezinga lokushisa phakathi kwengxenye ngayinye yezinto ezibonakalayo kungaphakathi kuka-±15 ° C; i-axial ne-radial (ithebula eliwumgogodla) ≤100°C.

6. Ingcindezi yohlelo lokuphakelwa kwamanzi okupholisa inkulu kuno-0.5MPa (umfutho wamanzi ojwayelekile mkhulu kuno-0.4 MPa), kanti izinga lokushisa eliphakeme lingu-60°C. Ukucindezela kwepayipi elihambisanayo nesixhumi esibonakalayo nakho kudinga ukwenyuswa ngokulinganayo kumazinga okuphepha.
