Mitambo ya Pressure Plate Zitsulo zachitsulo zomwe zimagwiritsidwa ntchito popanga ma boilers a nthunzi, zotengera zopondereza ndi zigawo zina zamakina otengera mphamvu.Chifukwa mbale yachitsulo iyi imakhala ndi kuthamanga kwa mpweya ndi kuthamanga kwa madzi, komanso malo ogwiritsira ntchito kutentha kosiyana, monga kutentha, sing'anga ndi kutentha kochepa, ndi zina zotero, zofunikira za mbale yachitsulo iyi ndizokhwima.
Kuwulutsa kwachidziwitso chazinthu
(1) Tanthauzo: Kuwonjezera pa kufuna nyonga ndi kulimba kwinakwake, zinthuzo zimafunikiranso kukhala zofanana, ndipo zilema zovulaza zimakhala zopereŵera.
(2) Mitundu: Malinga ndi gulu la zigawo, zikhoza kugawidwa m'magulu awiri: mbale za carbon steel ndi alloy steel plates;malinga ndi gulu la mphamvu, akhoza kugawidwa mu mbale mkulu, sing'anga ndi otsika kuthamanga zitsulo;Zitsulo mbale yachitsulo.
Makulidwe a mbale yokakamiza yotengera mbale nthawi zambiri amakhala mumtundu wa 5 mpaka 200mm, ndipo nthawiyo imagawidwa m'magawo angapo makulidwe.Miyezo yapadziko lonse imatchula masaizi ovomerezeka a mapepala ndi zopatuka zololeka.Maonekedwe abwino (1) Maonekedwe a mbale yachitsulo: monga camber, flatness, ngodya yolondola, ndi zina zotero (2) Zowonongeka pamwamba: Zowonongeka zazitsulo zazitsulo zimaphatikizapo ming'alu, zipsera, thovu lophwanyika, zonyansa, matuza, pores, mbamuikha chitsulo okusayidi sikelo, etc. Pazifukwa chitetezo, kuthamanga chotengera zitsulo mbale ali ndi zofunika okhwima pamwamba ndi zolakwika mkati.Zolakwika pamwambapa siziloledwa.Komabe, njira zoyenera zimaloledwa kuchotsedwa, ndipo malo ochotserako ayenera kukhala athyathyathya.Makulidwe ake sayenera kupitirira kusiyana kovomerezeka mu makulidwe a mbale yachitsulo.Interlayers nawonso saloledwa.Chemical composition index:
①Mbale yachitsulo ya carbon: makamaka kudziwa zomwe zili mu carbon, silicon, manganese, phosphorous ndi sulfure.Zitsulo zina za kaboni zimakhalanso ndi mkuwa, chromium, faifi tambala, molybdenum, vanadium ndi zinthu zina.Pakati pawo, carbon ndiye chinthu chachikulu chodziwira mphamvu ya mbale yachitsulo, ndiko kuti, mphamvu ya mbale yachitsulo imawonjezeka ndi kuwonjezeka kwa carbon.Mpweya wa carbon steel plate uli pakati pa 0.16 ndi 0.33%.Manganese ndi silicon amakhalanso ndi zotsatira zowonjezera zakuthupi ndikuwonjezera mphamvu.Silikoni: 0.10–0.55%, Manganese: 0.4–1.6%.Miyezo ina safuna silicon ndi manganese pa mbale za boiler wamba, ndipo mkuwa uli pansi pa 0,30%.Miyezo ina monga Japan ndi Russia ilibe zofunikira zamkuwa.Zitsulo zina zapamwamba zimakhala ndi chromium (pansi pa 0.25%), nickel (pansi pa 0.30%), molybdenum (pansi pa 0.10%), ndi vanadium (pansi pa 0.03%).Kapangidwe kake kazitsulo zazitsulo za boilers zamagulu osiyanasiyana kumawonetsedwa muzogulitsa zomwe zaperekedwa mu Gulu 6-7-3.
② Chitsulo chochepa cha alloy: Kuphatikiza pa zinthu za carbon steel, palinso kuchuluka kwa molybdenum, chromium, faifi tambala, vanadium, ndi zina. motere: 1/2 Mo, 1/2Mo-B zitsulo: ASTM A204, JIS G3107;Mn-1/2Mo1/2Mo, Mn-1/2Mo-V, Mn -1/2Mo-1/4Ni, Mn1/2Mo-1/2N ndi zitsulo: ASTM A302, A533, JIS G3119, G3120;1Cr-1/2Mo, 11/4Cr-1/2Mo, 21/2Cr-1Mo, 3C r-1Mo, 5Cr-1/2Mo, 7Cr-1/2Mo, 9Cr-1Mo: JISG4109, ASTM A387, A533, DIN1715.
③ Mbale yachitsulo yozimitsidwa komanso yotentha kwambiri: onani ASTM A517, A537, A724, A734, JISG3115.
④ Chitsulo chochepa cha kutentha: kuphatikiza chitsulo cha carbon ndi alloy steel.Mapangidwe a Chemical ndi makina amakina amapezeka mu ASTMA612, A 662, A735, A736, A738, A203, A645, JIS G3126.
⑤Chitsulo chosapanga dzimbiri: tchulani JIS G4304, ASTM A240, AISI13, ΓOCT5632.
