Isethi ephelele yemishini yokushisisa yokungeniswa yokwenyusa izinga lokushisa kwamapayipi ensimbi

1. Imingcele eyinhloko kanye nezidingo zomkhiqizo zesethi ephelele yezinto zokushisa zokungeniswa zokunyusa izinga lokushisa kwamapayipi ensimbi

Imishini esemqoka yalolu hlelo lokushisisa iqukethe ama-2000KVA ashintshashintshayo ezigaba eziyisithupha, amandla kagesi aphakathi kweshumi nambili angu-1500KW/1500Hz afanayo, amakhabethe amabili e-capacitor kanye namasethi amabili ama-inductors (amasethi ayi-6 lilinye), anamandla aphelele 3000KW. Isistimu yokulawula izinga lokushisa okuzenzakalelayo yakhiwa ikhompyutha yezimboni ye-Advantech, i-Siemens S7-300 PLC, amasethi amathathu amathemometha e-infrared anemibala emibili ye-American Raytek, amasethi amathathu okushintsha isithombe sika-Turck namasethi amabili emishini yokukala isivinini ye-BALLUFF. Isoftware yokulawula izimboni isoftware egunyaziwe yakwa-Siemens.

2. Izidingo zepharamitha yokucubungula

A. Ukucaciswa kwepayipi lensimbi:

Φ133×14 4.5m ubude (ububanzi bangempela bangaphandle bulawulwa ngezansi Φ135)

Φ102×12 3~4.0m ubude (ububanzi bangempela bangaphandle bulawulwa ngezansi Φ105)

Φ72×7 4.5m ubude (ububanzi bangempela bangaphandle bulawulwa ngezansi Φ75)

B. Izinto zamapayipi ensimbi: TP304, TP321, TP316, TP347, P11, P22, njll.

C. Izinga lokushisa lokushisa: mayelana ne-150℃, izinga lokushisa ngaphambi kokuba ishubhu yensimbi engagqwali ingene esithandweni: ikhanda licishe libe ngu-920℃950℃, umsila ucishe ube ngu-980℃ 1000℃, futhi izinga lokushisa langaphakathi lepayipi liphakeme kunelangaphandle. izinga lokushisa), izinga lokushisa eliphansi liyadingeka ukuze kushiswe futhi lonke izinga lokushisa likhuphukela ku (1070～1090) ℃ ekhanda nasemsileni, futhi umehluko wezinga lokushisa phakathi kwekhanda nomsila ulawulwa ngaphakathi kwamadigri angu-30 uma uphumile. wesithando somlilo.

D. Ukugoba okuphezulu kwepayipi lensimbi (ukuqondisa): 10mm/4500mm

F. Isivinini sokushisa: ≥0.30m~0.45m/sm/s

E. Heating process control: the uniformity of the discharge temperature should be ensured, and the deformation of the pipe should be reduced. The furnace body has a total of 6 sections, each section is about 500mm in length (each power supply controls the heating of 3 sections of the furnace body). At the entrance and exit of each group of furnaces Two-color thermometers are installed for temperature measurement, speed measurement devices are installed for speed measurement, and closed-loop temperature control is realized. Reliable and optimized control algorithms are used. After temperature simulation data collection and processing, data calculation, dynamic adjustment and precise control of the output of each group of furnace bodies Power, to ensure that the discharge temperature of different specifications of tube blanks tends to be consistent, and the uniformity is better, and it overcomes the danger of microscopic cracks caused by thermal stress.

Ukwengeza, ukuze wenze umehluko wesikhathi wesilinganiso sokushisa nge-thermometer futhi uthuthukise ukuzwela kokulawula, idivayisi yokubona umzimba oshisayo ifakwe emnyango kanye nokuphuma kweqembu ngalinye lezithando ukwenza isithando sokushisa sibe bucayi futhi okuthembekile ekugcineni amandla kanye nokushintsha kwamandla aphezulu phakathi kwezinto ezingagcwalisiwe nezigcwele.

Inombolo yemodeli: RFM2 1.4—2000—1.5S

I-capacitor ifakwe ngaphansi kohlaka lwesithando somlilo mayelana ne-500mm ngaphansi kwesitezi sefreyimu yesithando somlilo, ukujula komsele kukhulu kunamamitha angu-1.00, futhi ububanzi bomsele bungamamitha angu-1.4.

b. Izidingo zamapayipi okupholisa amanzi

Yenziwe ngensimbi engagqwali ewugqinsi, ipayipi lokungena lamanzi elingamayintshi angu-3.5, ipayipi lokubuya lamanzi elingamayintshi angu-4, namanye amapayipi angu-2.5-intshi, okuhlanganisa okufakwayo namaswishi ensimbi engagqwali.

6. Inductor kanye nezidingo zomlilo

Amaphethelo amabili omzimba wesithando somlilo athatha amapuleti okuvikela ithusi ukuze anciphise ukuvuza kazibuthe, kanye nomklamo wokugeleza kwamanzi kumzuliswano womlomo wesithando somlilo. I-chassis yenziwe ngensimbi engagqwali engeyona uzibuthe. Ishubhu yethusi ilinyazwe ngethusi elingenawo umoya-mpilo we-T2, ubukhulu bodonga lweshubhu yethusi bukhulu noma bulingana no-2.5mm, futhi izinto ezifakwa esithandweni somlilo zenziwe ngezinto zokufiphaza ze-American Union Ore, ezinamandla aphezulu, izinga lokushisa eliphezulu. ukumelana nempilo ende yesevisi; ipuleti lonogada bomlilo wesithando somlilo lithatha amandla aphezulu Ibhodi le-insulating eliwugqinsi. I-inlet kanye namanzi abuyayo omzimba wesithando somlilo athatha insimbi engenasici eshintsha ngokushesha amalunga, alungele ukushintshwa kwesithando somlilo.

Kukhona imbobo yokukhipha amanzi ngaphansi kwesithando somlilo sokungeniswa, esingakhipha ngokuzenzakalelayo amanzi ajiyile esithandweni somlilo.

7. Izidingo zobakaki ophakamisayo wenzwa

a. Kufakwe isamba sezinzwa eziyisi-6 phakathi kwamatafula e-roller ukuze kufakwe izinzwa.

b. Ukuze uvimbele ubakaki ukuthi bangashisi, ipuleti elingaphansi le-inductor kanye nepuleti eliphezulu labakaki kwenziwa ngensimbi engagqwali engeyona i-magnetic.

c. Ukuze uthole amapayipi ensimbi ama-diameter ahlukene, izinzwa ezihambisanayo zidinga ukushintshwa futhi ukuphakama kwesikhungo kungalungiswa.

d. Izimbobo ze-bolt zenzwa zenziwe zibe izimbobo ezinde ukuze zilungiswe kalula.

e. Ubude obumaphakathi benzwa bungalungiswa yi-stud nut ku-mounting plate yenzwa.

f. Amabha amabili ethusi axhumayo angaphansi kwe-inductor kanye nekhebula elipholiswe ngamanzi elisuka kukhabethe le-capacitor ngayinye ixhunywe ngamabholithi angu-4 ensimbi engagqwali (1Cr18Ni9Ti).

g. The water inlet and outlet pipes of the sensor and the main water pipe are connected by quick-change joints and hoses, which are not affected by the position error, and realize the rapid connection of the sensor waterway.

8. Ipayipi lensimbi eligxilisa amanzi okupholisa nokucindezela idivayisi

Ukuze uvimbele ipayipi lensimbi ukuthi lingashayi ngobudlova inzwa ngesikhathi sokudlulisa ngesithando sokufakwa ngaphakathi futhi libangele ukulimala kwenzwa, idivayisi yokuqondisa ipayipi yensimbi eqhutshwa ngamandla kufanele ifakwe endaweni yokungena nasekupheleni kokuphakelwa kukagesi ngakunye ukuze kuqinisekiswe ukuthi ipayipi lensimbi lidlula inzwa kahle. Ngaphandle kokushaya umzimba wesithando somlilo. Ukuphakama kwale divayisi kuyalungiseka, kufanelekile φ72, φ102, kanye namapayipi ensimbi φ133. Ijubane lale divayisi liyalungiseka, kusetshenziswa i-Siemens frequency conversion motor kanye ne-frequency converter, uhla lokulungisa isivinini sokuguqulwa kwemvamisa lungaphansi kwezikhathi eziyi-10. Amarola apholile amanzi enziwe ngensimbi engagqwali engeyona kazibuthe.

9. Uhlelo lokupholisa amanzi oluvaliwe

a. Umshini wokupholisa ovaliwe onokugeleza okuphelele kwamanzi okupholisa esithandweni angu-200 m3/h wabelana ngesethi eyodwa noma isethi eyodwa ngayinye, kodwa ukunikezwa kwamandla okuvama okumaphakathi, i-resonance capacitor, kanye nesistimu yamanzi yezinzwa kuyadingeka ukuthi kuhlukaniswe ukuze kuvinjelwe ukuphazamiseka. Isisetshenziswa sokupholisa esivaliwe kufanele senziwe ngensimbi esakazwa yi-hot-dip galvanized, izifeni zegama lomkhiqizo, amaphampu amanzi kanye nezingxenye zokulawula.

b. Ipayipi lokupholisa amanzi liyadingeka ukuba lenziwe ngensimbi engenasici enodonga oluqinile, okuhlanganisa nezixhumi zepayipi lensimbi engagqwali namaswishi.
