I-P235GH ST35.8 SA192 Ipayipi Lensimbi Engenamthungo / Ishubhu le-Boiler

Isethulo somkhiqizo

Izakhiwo zemishini yepayipi ye-boiler iyinkomba ebalulekile yokuqinisekisa ukusebenza kokugcina kwenkonzo (izakhiwo zemishini) yensimbi, okuncike ekubunjweni kwamakhemikhali kanye nesistimu yokushisa ukushisa kwensimbi.Ezingeni lepayipi lensimbi, ngokwezidingo ezihlukene zokusetshenziswa, lisho ukusebenza okuqinile (amandla okuqina, amandla esivuno noma iphuzu lesivuno, ubude), kanye nezinkomba zokuqina nokuqina, kanye nokusebenza kwezinga lokushisa eliphezulu neliphansi elidingwa abasebenzisi. .
① Izinga lokushisa elisetshenziswa kubhayela elijwayelekile lingaphansi kuka-350℃, futhi ipayipi lasekhaya lenziwa ikakhulukazi nge-10 kanye ne-20 carbon junction steel ipayipi elishisayo eligoqwayo noma ipayipi elibandayo.Amazwe angaphandle asetshenziswa kakhulu i-P235GH, SA192, ST35.8,106B, 210A1,210C
② Ipayipi elinomfutho ophakeme we-boiler livame ukusetshenziswa emazingeni okushisa aphezulu kanye nezimo zengcindezi ephezulu, ipayipi ngaphansi kwesenzo sokushisa okuphezulu kwegesi ye-flue kanye nomhwamuko wamanzi, i-oxidation kanye nokugqwala kuzokwenzeka.Ipayipi lensimbi elidingekayo linamandla ahlala isikhathi eside, i-oxidation ephezulu kanye nokumelana nokugqwala, kanye nokuzinza okuhle kwezicubu.
Ipayipi le-boiler lisetshenziselwa ikakhulukazi ukwenza ipayipi lamanzi odongeni, ipayipi lamanzi abilayo, ipayipi le-steam elishisa kakhulu, ipayipi le-steam elishisa kakhulu le-boiler ye-locomotive, ipayipi lentuthu elikhulu nelincane kanye nepayipi lezitini le-arch, njll.

Indlela yokuhlola ikhwalithi yepayipi lensimbi engenamthungo

1. Ukuhlaziywa kokwakheka kwamakhemikhali: indlela yokuhlaziya amakhemikhali, ukuhlaziywa kwensimbi (insimbi ye-infrared CS, i-spectrometer yokufunda eqondile, i-zcP, njll.).
2. Ukuhlolwa kwekhwalithi yobuso bepayipi lensimbi: 100%
A. Ukutholwa kwe-Ultrasonic UT:
B. ET: (i-electromagnetic induction)
C. MT nokutholwa kokuvuza:
Ukutholwa kwamaphutha kazibuthe, kulungele ukutholwa kokulimala okungaphezulu naseduze kobuso bezinto ze-ferromagnetic.
D. Ukutholwa kwephutha kwe-Electromagnetic ultrasonic:
Ayikho indlela yokuhlanganisa edingekayo, engasetshenziswa kumazinga okushisa aphezulu kanye nesivinini esikhulu, amapayipi ensimbi anomahhadlahhadla futhi omile ekuboneni amaphutha angaphezulu.
E. ukuhlolwa kokungena koketshezi:
I-Fluorescence, ukufaka umbala, kanye nokutholwa kokulimala kwepayipi lensimbi.
3. Ukuhlolwa kokusebenza ngokomzimba namakhemikhali kwepayipi lensimbi;
4. Ukuhlolwa kokusebenza kwenqubo yepayipi lensimbi:
① Ukuhlolwa okuyisicaba: isampuli eyindilinga isampuli emise okuka-C (S / D & gt; 0.15) H= (1 + 2) S / (+ S / D)
L=40~100mm iyunithi ngayinye yobude bokuguquguquka =0.07~0.08
② Ukuhlolwa kokudonsa: L=15mm ngaphandle kwe-crack ifanelekile
③ Ukuhlolwa kokunwetshwa nokugoqa: i-taper ephezulu ingu-30°, 40° no-60°
④ Ukuhlolwa kokugoba: kungangena esikhundleni sokuhlolwa okucaba (ngepayipi elikhulu lobubanzi).
