Q1: Hauv kev lag luam tsheb thiab tshuab, cov khoom tshwj xeeb dab tsi feem ntau tsim siv Q420 welded kav?
A1:Q420 yog dav siv rau kev tsim khoom hnyav- lub luag haujlwm tsheb chassis, crane booms, excavator caj npab thav duab, thiab tsheb nrau av. Nws lub zog siab tso cai rau cov khoom no tuaj yeem tiv taus qhov hnyav hnyav thiab hnyav hnyav thaum khaws tag nrho qhov hnyav ntawm lub tshuab tswj tau.
Q2: Yuav ua li cas qaug zog tiv thaiv ntawm Q420 welded yeeb nkab ntsuas, thiab vim li cas qhov no tseem ceeb rau daim ntawv thov kev thauj khoom cyclic
A2:Kev qaug zog tiv thaiv yog ntsuas los ntawm kev sim qaug zog, uas ntsuas tus naj npawb ntawm cov voj voog ib lub yeeb nkab tuaj yeem tiv taus nyob rau hauv ib qho kev thauj khoom ua ntej tsis ua hauj lwm. Q420 muaj kev qaug zog zoo heev vim nws cov qauv ua kom zoo zoo. Qhov no yog qhov tseem ceeb rau cov ntawv thov xws li cov tshuab conveyor, vibrating cov ntxaij vab tshaus, thiab cua turbine txhawb cov qauv uas cov khoom hloov pauv tas li.
Q3: Dab tsi yog qhov tsis xws luag uas tuaj yeem tshwm sim hauv Q420 welded kav thaum lub sijhawm tsim khoom, thiab lawv kuaj tau li cas?
A3:Feem ntau cov teeb meem muaj xws li tsis muaj fusion, porosity, thiab HAZ softening. Cov no raug kuaj pom siv tsis yog -kev kuaj kev puas tsuaj (NDT) txoj hauv kev:Kev kuaj ultrasonic (UT)kuaj pom cov teeb meem sab hauv xws li tsis muaj fusion;Kev ntsuas hluav taws xob (RT)txheeb xyuas porosity thiab slag inclusions; thiabSib Nqus Particle Test (MT)yog siv los nrhiav cov kab nrib pleb hauv qhov weld seam.
Q4: Q420 welded kav puas tuaj yeem ua tau txias-, thiab yuav tsum tau ceev faj dab tsi?
A4:Q420 tuaj yeem txias- tsim tab sis muaj teeb meem ntau dua li Q390. Vim nws lub zog tawm los ntau dua, cov tshuab tshwj xeeb nrog cov tonnage ntau dua yog xav tau. Kev ceev faj muaj xws li siv cov menyuam tuag nrog cov chaw du kom tsis txhob khawb qhov chaw thiab siv lubrication los tiv thaiv cov cuab yeej siv thiab cov khoom tawg thaum lub sij hawm tsim.
Q5: Lub luag haujlwm ntawm Q420 welded kav yog dab tsi hauv kev tsim kho ntev - ncua qhov chaw ncej?
A5:Q420 yog lub caj qaum ntawm qhov ntev - ncua qhov chaw thav duab (xws li lub ru tsev chaw ntau pob thiab tshav dav hlau terminals). Nws lub zog tshwj xeeb siab (lub zog-rau- qhov hnyav piv)) tso cai rau cov kws tsim khoom tsim cov chaw loj dua, qhib ntau yam tsis muaj kab nruab nrab. Siv Q420 txo qis cov hlau xav tau, ua rau kom txuag tau tus nqi ntau thiab kev tsim kho kom ruaj khov.
