Cov kev cai thiab cov txheej txheem xeem yog cov ntsiab lus tseem ceeb

Cov qauv siv tseem ceeb rau cov tubular tso cua sov rau cov dej rhaub dej yog JB/T4088-1999 Tubular Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob rau Kev Siv Txhua Hnub, uas tsom mus rau kev ua kom zoo dua cov kev cai rau cov kav hluav taws xob cua sov siv hauv hluav taws xob cua sov, qhia txog cov kev cai thiab kev sim rau cua sov raj, thiab feem ntau yog ntsuas qhov kev ua tau zoo ntawm cov cua sov raj.

Cov kev cai ntawm cov kev cai ntawm cov txheej txheem muaj xws li ntau yam, ntawm cov uas, qhov yuav tsum tau rau cov khoom kev ruaj ntseg kev ua tau zoo yog hais tias lub txias hluav taws xob lub zog ntawm hluav taws xob cua sov raj yuav tsum tsis txhob muaj flashover los yog tawg rau 1 feeb nyob rau hauv ib tug yooj yim sine yoj voltage ntawm 1500V, thiab cov xau tam sim no yuav tsum tsis pub tshaj 5mA; Cov xau tam sim no ntawm lub tshuab hluav taws xob cua sov nyob rau hauv ib txwm ua haujlwm yuav tsum tsis pub tshaj 3mA; Lub zog input ntawm lub tshuab hluav taws xob cua sov yuav tsum nyob rau hauv thaj tsam ntawm 90% mus rau 105% ntawm lub zog ntsuas. Cov txheej txheem siab xav tau rau cov kav hluav taws xob cua sov yog "Tom qab 48 teev ntawm kev ntsuas kub ntub dej, lawv yuav tsum muaj peev xwm tiv taus qhov ntsuas hluav taws xob ntawm 1500V rau 1 feeb ntawm kev ntsuas hluav taws xob, thiab cov xau tam sim no yuav tsum tsis pub tshaj 5mA."

Nws yog to taub hais tias cov kev cai rau tubular tso cua sov rau cov dej rhaub tshwj xeeb muaj xws li yuav tsum tau rau qhuav burning kev ua tau zoo. "Lub raj hluav taws xob cua sov yuav tsum raug rho tawm cua sov rau 30 feeb nyob rau hauv qhov ntsuas hluav taws xob ua haujlwm, tsis muaj deformation lossis tso tawm cov nplaim taws, cov ntsiab lus hlau, thiab cov pa phem. ib feem ntawm lub raj lub cev tshwj tsis yog lub flange yuav tsum tau muab tso rau hauv dej Tom qab 24 teev, nws yuav tsum muaj peev xwm tiv taus qhov ntsuas hluav taws xob ntawm 1250V rau 1 feeb ntawm kev ntsuas hluav taws xob, thiab cov dej xau yuav tsum tsis pub tshaj 5mA nto load ntau dua 11W / cm2 tsis tas yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua, thiab tooj liab thiab txhuas raj tsis haum. " "Kev ua kom qhuav qhuav yog ib yam uas peb xav tau kom suav nrog hauv tus qauv." Raws li ib qho tseem ceeb ntawm lub tshuab ua lag luam hauv pab pawg tsim qauv, Zhou Liguo, Tus Thawj Saib Xyuas Zoo ntawm Guangdong Midea Chav Ua Noj thiab Chav Dej Hluav Taws Xob Khoom Siv Hluav Taws Xob Co., Ltd., tau hais rau cov neeg sau xov xwm tias dej zoo hauv ntau qhov chaw ntawm Tuam Tshoj. "Txawm li cas los xij, qee qhov dej tsis zoo yog qhov ua tau zoo, uas ua rau muaj kev xav tau siab rau kev ua kom qhuav ntawm cov hluav taws xob cua sov raj. Tsis tas li ntawd, thaum lub tshuab rhaub dej rhaub cov tuam txhab ntsuas qhov zoo ntawm cov hluav taws xob cua sov, qhov zoo ntawm cov hluav taws kub kub ua haujlwm ncaj qha qhia. qhov zoo ntawm cov khoom siv, yog li nws yog ib qho tsim nyog yuav tsum tau ua raws li cov txheej txheem rau qhov no.

Tsis tas li ntawd, cov kev cai tseem ceeb hauv cov kev cai tseem ceeb kuj muaj xws li: cov xaim hluav taws xob tawm hauv lub tshuab hluav taws xob cua sov yuav tsum muaj peev xwm tiv taus qhov ntsuas tensile ntawm 980N rau 3 feeb, tsis muaj kev hloov pauv, tawg lossis lwm yam tshwm sim; Lub vuam ntawm lub davhlau ya nyob twg thaiv thiab cov hlau lead tawm pas nrig yuav tsum muaj peev xwm tiv taus lub zog tensile ntawm ntau tshaj 200N nyob rau hauv ob qho tib si ntsug thiab kab rov tav cov lus qhia, thiab yuav tsum tsis muaj phenomena xws li breakage los yog detachment; Tom qab qhov kev ntsuas kub thiab qis qis, nws yuav tsum muaj peev xwm tiv taus qhov ntsuas hluav taws xob ntawm 1500V rau 1 feeb ntawm kev ntsuas hluav taws xob, thiab cov xau tam sim no yuav tsum tsis pub tshaj 5mA; Lub raj hluav taws xob cua sov yuav tsum muaj peev xwm tiv taus qhov ntsuas 24- teev ntsev ntsev, thiab yuav tsum tsis txhob muaj xeb hnyav rau ntawm qhov hluav taws xob cua sov raj uas tuaj yeem tiv nrog dej thaum siv lub tshuab rhaub dej; Lub neej ua haujlwm ntawm lub tshuab hluav taws xob cua sov yuav tsum tsis pub tsawg dua 4000 teev.
