Dab tsi hnyav ib puag ncig yuav tsum koj lub hlwb load tiv taus?
Kab lus no piav qhia yuav ua li cas xaiv aload celluas yuav ua tau zoo nyob rau hauv ib puag ncig hnyav thiab hnyav ua haujlwm.
Load cells yog cov khoom tseem ceeb hauv txhua qhov hnyav, lawv paub qhov hnyav ntawm cov khoom hauv lub thawv hnyav, lwm lub thawv lossis cov khoom siv ua haujlwm. Hauv qee qhov kev siv, lub cev thauj khoom yuav raug cuam tshuam rau qhov chaw hnyav nrog cov tshuaj corrosive, hnyav plua plav, kub kub, lossis dej noo ntau dhau los ntawm cov khoom siv yaug nrog cov kua dej ntau. Los yog lub xov tooj ntawm tes yuav raug cuam tshuam rau kev vibration siab, tsis sib npaug, lossis lwm yam kev ua haujlwm hnyav. Cov xwm txheej no tuaj yeem ua rau hnyav qhov tsis raug thiab, yog tias xaiv tsis raug, txawm tias ua rau lub cev puas tsuaj. Txhawm rau xaiv qhov tsim nyog load cell rau daim ntawv thov, koj yuav tsum nkag siab tag nrho koj ib puag ncig thiab kev ua haujlwm, thiab cov yam ntxwv ntawm lub xov tooj twg yog qhov zoo tshaj plaws los daws lawv.
Dab tsi ua raudaim ntawv thovnyuaj?
Thov ua tib zoo saib ib puag ncig ib puag ncig ntawm qhov hnyav thiab nyob rau hauv qhov kev ua haujlwm uas lub kaw lus yuav tsum ua haujlwm.
Puas yuav muaj plua plav?
Puas yog lub cev hnyav yuav raug kub siab tshaj 150 ° F?
Dab tsi yog qhov tshuaj ntawm cov khoom raug hnyav?
Puas yog lub kaw lus puas yuav raug ntxuav nrog dej lossis lwm yam tshuaj ntxuav? Yog tias cov tshuaj ntxuav tu yuav tsum tau siv los ntxuav cov cuab yeej, lawv cov yam ntxwv zoo li cas?
Puas yog koj txoj kev yaug dej ua rau cov khoom thauj khoom mus rau cov dej noo ntau dhau? Cov kua yuav raug txau ntawm qhov siab? Puas yog lub cell load yuav submerged nyob rau hauv cov kua thaum lub sij hawm flushing txheej txheem?
Puas tuaj yeem thauj cov hlwb tsis sib npaug vim yog cov khoom tsim lossis lwm yam mob?
Puas yog lub kaw lus puas raug cuam tshuam rau kev poob siab (sdden loj loads)?
Puas yog cov khoom thauj tuag (cov thawv lossis cov khoom siv uas muaj cov khoom siv) ntawm qhov hnyav qhov sib npaug loj dua li cov khoom nyob (khoom siv)?
Lub kaw lus puas yuav raug kev vibrations siab los ntawm cov tsheb dhau los lossis nyob ze ua haujlwm lossis tuav cov khoom siv?
Yog hais tias lub cev hnyav yog siv rau hauv cov txheej txheem cov cuab yeej, puas yuav raug rau siab torque rog los ntawm cov khoom motors?
Thaum koj nkag siab txog cov xwm txheej uas koj lub cev hnyav yuav ntsib, koj tuaj yeem xaiv lub xov tooj ntawm tes nrog cov yam ntxwv raug uas yuav tsis tsuas yog tiv taus cov xwm txheej no, tab sis yuav ua tau zoo dua lub sijhawm. Cov ntaub ntawv hauv qab no piav qhia cov yam ntxwv ntawm lub xov tooj ntawm tes uas muaj los tswj koj daim ntawv thov xav tau.
Cov khoom siv hauv tsev
Rau kev pab xaiv cov khoom thauj khoom zoo rau koj cov kev xav tau, sab laj nrog tus neeg muag khoom muaj peev xwm lossis tus kws pab tswv yim txog kev tuav cov khoom lag luam. Cia siab tias yuav muab cov ncauj lus kom ntxaws txog cov khoom siv lub cev hnyav yuav tuav, qhov chaw ua haujlwm, thiab cov xwm txheej twg yuav cuam tshuam rau kev ua haujlwm ntawm lub xov tooj ntawm tes.
Lub xovtooj ntawm tes yog qhov tseem ceeb ntawm cov khoom siv hlau uas khoov teb rau qhov kev thov. Cov khoom no suav nrog cov ntsuas ntsuas hauv Circuit Court thiab tuaj yeem ua los ntawm cov cuab yeej hlau, txhuas lossis stainless hlau. Cov cuab yeej steel yog cov khoom siv ntau tshaj plaws rau kev thauj cov hlwb hauv cov ntawv thov qhuav vim nws muaj kev ua tau zoo ntawm tus nqi qis thiab muaj peev xwm loj. Cov cuab yeej steel load hlwb muaj rau ob qho tib si taw tes thiab multipoint load cell (paub tias yog ib qho taw tes thiab multipoint). Nws ua hauj lwm zoo tshaj plaws nyob rau hauv qhuav tej yam kev mob, raws li noo noo tuaj yeem xeb cov cuab yeej steels. Cov cuab yeej nrov tshaj plaws hlau alloy rau cov hlwb no yog hom 4340 vim nws yooj yim rau tshuab thiab tso cai rau kev kho cua sov kom zoo. Nws kuj tseem rov qab mus rau nws qhov tseeb pib txoj haujlwm tom qab qhov kev thov load raug tshem tawm, txwv tsis pub nkag (maj mam nce hauv qhov hnyav ntawm tes nyeem ntawv thaum tib lub thauj khoom siv) thiab hysteresis (ob qhov hnyav ntawm tib qho kev thov load Qhov sib txawv ntawm kev nyeem ntawv, ib qho. tau los ntawm kev nce lub load ntawm xoom thiab lwm yam los ntawm kev txo cov load mus rau qhov siab tshaj plaws rated peev ntawm lub load cell). Aluminium yog cov khoom siv hluav taws xob tsawg tshaj plaws thiab feem ntau yog siv los thauj cov hlwb hauv ib qho taw tes, daim ntawv thov ntim tsawg. Cov khoom no tsis haum rau siv nyob rau hauv ntub dej los yog tshuaj lom neeg ib puag ncig. Hom 2023 txhuas yog qhov nrov tshaj plaws vim tias, zoo li hom 4340 cov cuab yeej hlau, nws rov qab mus rau nws qhov tseeb pib txoj haujlwm tom qab tau hnyav, txwv tsis pub nkag thiab hysteresis. Lub zog thiab corrosion kuj ntawm 17-4 PH (kev tshuaj xyuas hardened) stainless hlau (tseem hu ua qib 630 stainless hlau) muab nws qhov zoo tshaj plaws tag nrho kev ua tau zoo ntawm txhua yam stainless hlau derivative rau load hlwb. Cov hlau no kim dua li cov cuab yeej hlau lossis txhuas, tab sis muaj qhov ua tau zoo tshaj plaws ntawm cov khoom siv hauv cov ntaub ntawv ntub dej (piv txwv li cov uas yuav tsum tau ntxuav kom dav) thiab kev siv tshuaj lom neeg. Txawm li cas los xij, qee cov tshuaj yuav tawm tsam Hom 17-4 PH alloys. Hauv cov ntawv thov no, ib qho kev xaiv yog siv cov txheej nyias ntawm cov xim epoxy (los ntawm 1.5 mus rau 3 hli tuab) rau cov hlau tsis muaj steel load cell. Lwm txoj hauv kev yog xaiv lub xov tooj ntawm tes ua los ntawm cov hlau alloy, uas tuaj yeem tiv taus corrosion zoo dua. Rau kev pab xaiv cov khoom siv thauj khoom tsim nyog rau kev siv tshuaj lom neeg, xa mus rau cov kab kos tshuaj tiv thaiv (ntau muaj nyob hauv Is Taws Nem) thiab ua haujlwm ze nrog koj tus neeg xa khoom thauj khoom.
