Seti yathunthu ya zida zotenthetsera zopangira zitsulo zokweza kutentha kwa chitoliro

1. Zofunikira zazikulu ndi zofunikira zamtundu wa zida zonse zotenthetsera zotenthetsera pakukweza kutentha kwa chitoliro

Zida zazikulu zamakina otenthawa zimakhala ndi ma 2000KVA osinthira magawo asanu ndi limodzi, ma pulse 1500-pulse 1500KW/6Hz ofanana ma frequency frequency amagetsi, makabati awiri a capacitor ndi seti ziwiri za ma inductors (ma seti 3000 aliwonse), okhala ndi mphamvu zonse. 7KW. Makina owongolera kutentha amapangidwa ndi kompyuta yamakampani ya Advantech, Nokia S300-XNUMX PLC, ma seti atatu a American Raytek ma thermometers amitundu iwiri, ma switch atatu a Turck photoelectric ndi zida ziwiri zoyezera liwiro la BALLUFF. Pulogalamu yoyang’anira mafakitale ndi pulogalamu yovomerezeka ya Siemens.

2. Zofunikira za parameter

A. Mapaipi achitsulo:

Φ72 × 7 4.5m kutalika (m’mimba mwake weniweni wakunja umayendetsedwa pansipa Φ75)

B. Steel pipe material: TP304, TP321, TP316, TP347, P11, P22, etc.

C. Heating temperature: about 150℃, the temperature before the stainless steel tube enters the furnace: the head is about 920～950℃, the tail is about 980～1000℃, and the internal temperature of the pipe is higher than the external temperature), the low temperature end is required to be heated and the whole The temperature is raised to (1070～1090) ℃ at the head and tail, and the temperature difference between the head and tail is controlled within 30 degrees when it is out of the furnace.

D. Maximum bend of steel pipe (straightness): 10mm/4500mm

F. Heating speed: ≥0.30m~0.45m/sm/s

E. Kuwotcha njira yoyendetsera: kufanana kwa kutentha kwazitsulo kuyenera kutsimikiziridwa, ndipo kusinthika kwa chitoliro kuyenera kuchepetsedwa. Thupi la ng’anjo lili ndi zigawo za 6, gawo lirilonse liri pafupi ndi 500mm kutalika (magetsi aliwonse amawongolera kutentha kwa magawo atatu a ng’anjo yamoto). Pakhomo ndi potuluka gulu lililonse la ng’anjo Ma thermometers amitundu iwiri amayikidwa kuti ayese kutentha, zida zoyezera liwiro zimayikidwa kuti ziyezetse liwiro, ndipo kuwongolera kutentha kwapakati kumachitika. Ma algorithms odalirika komanso okhathamiritsa amagwiritsidwa ntchito. Pambuyo kutentha kayeseleledwe deta zosonkhanitsira ndi processing, mawerengedwe deta, kusintha kwamphamvu ndi kulamulira yeniyeni linanena bungwe gulu lililonse la ng’anjo matupi Mphamvu, kuonetsetsa kuti kumaliseche kutentha specifications osiyana chubu akusowekapo amakhala wogwirizana, ndi yunifolomu bwino, ndipo imagonjetsa kuopsa kwa ming’alu ya microscopic yoyambitsidwa ndi kupsinjika kwa kutentha.

Kuphatikiza apo, kuti apange kusiyana kwa nthawi ya kuyeza kwa kutentha ndi thermometer ndikuwongolera kuwongolera kowongolera, chipangizo chodziwikiratu chowotcha chimayikidwa pakhomo ndi kutuluka kwa gulu lililonse la ng’anjo kuti ng’anjo yotentha ikhale yovuta komanso odalirika pakusunga mphamvu ndi kusintha kwamphamvu kwamphamvu pakati pa zinthu zosadzazidwa ndi zodzaza.

3. Six-phase rectifier rectifier parameters ndi zofunikira zogwirira ntchito:

Zida zonse zimagwiritsa ntchito zosinthira ziwiri za 2000KVA, chilichonse chili ndi mawonekedwe 12-pulse rectifier. Zofunikira zazikulu ndi izi:

Kuchuluka kwake: Sn = 2000KVA

Mpweya woyambira: U1=10KV 3φ 50Hz

Mphamvu yachiwiri: U2=660V

Njira yozizirira: kuziziritsa kwachilengedwe komizidwa ndi mafuta

Protection function: heavy gas trip, light gas trip, pressure release switch, oil over-temperature alarm

Ndi ± 5%, 0% magawo atatu amagetsi owongolera mbali yothamanga kwambiri

4. Zofunikira zazikulu ndi zofunikira zogwirira ntchito zamagetsi apakatikati pagawo lathunthu la kutentha kwa chitoliro chachitsulo chokweza zida zotenthetsera:

Mphamvu yolowera: 660V

Mphamvu yamagetsi ya DC: 890V

DC yapano: 1700A

Mphamvu yapakati pafupipafupi: 1350V

Mafupipafupi apakati: 1500Hz

Mphamvu yapakati pafupipafupi: 1500KW / iliyonse

5. Zofunikira za kabati ya capacitor

a, kusankha capacitor

1500Hz magetsi otenthetsera capacitor opangidwa ndi Xin’anjiang Power Capacitor Factory

Nambala yachitsanzo: RFM2 1.4-2000-1.5S

The capacitor is installed under the furnace frame about 500mm below the floor of the furnace frame, the trench depth is greater than 1.00 meters, and the trench width is 1.4 meters.

b. Zofunikira papaipi yozizirira madzi

Zopangidwa ndi chitsulo chosapanga dzimbiri, chitoliro cholowera madzi cha mainchesi 3.5, chitoliro chobwezera madzi cha mainchesi 4, ndi mapaipi ena a mainchesi 2.5, kuphatikiza zolumikizira ndi masiwichi achitsulo chosapanga dzimbiri.

6. Zofunikira za Inductor ndi ng’anjo

The two ends of the furnace body adopt copper guard plates to reduce magnetic leakage, and the design of water flow in the circumference of the furnace mouth. The chassis is made of non-magnetic stainless steel. The copper tube is wound with T2 oxygen-free copper, the wall thickness of the copper tube is greater than or equal to 2.5mm, and the furnace body insulation material is made of American Union Ore knotting material, which has high strength, high temperature resistance and longer service life; the furnace body guard plate adopts high strength Thick insulating board. The inlet and return water of the furnace body adopts stainless steel quick-change joints, which is convenient for the replacement of the furnace body.

Pansi pa ng’anjo yopangira ng’anjo pali bowo, lomwe limatha kukhetsa madzi osungunuka mung’anjoyo.

7. Zofunikira pakukweza bracket ya sensor

a. Mabaketi okwana 6 amayikidwa pakati pa matebulo odzigudubuza kuti akhazikitse masensa.

b. Pofuna kuteteza kuti bulaketi isatenthedwe, mbale yapansi ya inductor ndi mbale ya pamwamba ya bracket imapangidwa ndi chitsulo chosapanga dzimbiri chosapanga maginito.

c. Kwa mapaipi achitsulo amitundu yosiyanasiyana, masensa ofananira amafunika kusinthidwa ndipo kutalika kwapakati kumatha kusinthidwa.

d. Mabowo a bolt a sensor amapangidwa kukhala mabowo aatali kuti asinthe mosavuta.

e. Kutalika kwapakati kwa sensa kumatha kusinthidwa ndi mtedza wa stud mu mbale yokwera sensor.

f. Mipiringidzo iwiri yamkuwa yolumikiza pansi pa inductor ndi chingwe choziziritsa madzi kuchokera ku capacitor cabinet iliyonse imalumikizidwa ndi zitsulo 4 zosapanga dzimbiri (1Cr18Ni9Ti).

g. Kulowetsa madzi ndi mapaipi otulutsa a sensa ndi chitoliro chachikulu chamadzi amalumikizidwa ndi kulumikizana mwachangu ndi ma hoses, omwe samakhudzidwa ndi cholakwika cha malo, ndikuzindikira kulumikizana mwachangu kwa sensa yamadzi.

h. Masensa amatha kusinthidwa mwachangu, ndipo nthawi iliyonse yosinthira imakhala yochepera mphindi 10, ndipo imakhala ndi ma trolleys awiri m’malo mwa masensa.

8. Chitoliro chachitsulo centering madzi kuzirala ndi kukanikiza chipangizo

Kuti muteteze chitoliro chachitsulo kuti chisamenye mwamphamvu sensa panthawi yotumizira kudzera mu ng’anjo yolowera ndikuyambitsa kuwonongeka kwa sensa, chipangizo chachitsulo choyendetsa chitoliro chachitsulo chiyenera kukhazikitsidwa pamapeto amagetsi onse kuti atsimikizire kuti Chitoliro chachitsulo chimadutsa mu sensa bwino. Popanda kugunda thupi la ng’anjo. Kutalika kwa chipangizochi ndi chosinthika, choyenera φ72, φ102, ndi φ133 mapaipi achitsulo. Liwiro la chipangizo ichi ndi chosinthika, ntchito Siemens pafupipafupi kutembenuka galimoto ndi pafupipafupi Converter, pafupipafupi kutembenuka liwiro kusintha osiyanasiyana zosakwana 10 nthawi. Ma roller oziziritsidwa ndi madzi amapangidwa ndi chitsulo chosapanga dzimbiri chosapanga maginito.

9. Njira yoziziritsira madzi yotsekedwa

a. The closed cooling device with the total flow of the furnace cooling water of 200 m3/h shares one set or one set of each, but the intermediate frequency power supply, resonance capacitor, and sensor water system are required to be separated to prevent interference. The closed cooling device should be made of imported hot-dip galvanized steel, brand-name fans, water pumps and control components.

b. Paipi yozizirira madzi imayenera kupangidwa ndi zitsulo zosapanga dzimbiri zokhala ndi mipanda, kuphatikiza zopangira ndi ma switch achitsulo chosapanga dzimbiri.
