Cais me me Txij li thaum xyoo 1930 los, lub tshuab hluav taws xob me me tau tsim los ua kom tau raws li ntau yam kev thov, suav nrog kev siv dav hlau, khoom siv hauv tsev, tswj kav dej, khoom siv kho mob, ntsuas tshuab, kuaj. Cov khoom siv sijhawm, sijhawm thiab tshuab muag khoom. Hloov me me
Feem ntau siv los txhawm rau ntsuas kub, txoj haujlwm thiab theem kua.
Precision microswitches muaj nyob rau peb qhov ntau thiab tsawg: qhov pib, nrog joystick, nrog kev siv tes ua haujlwm thiab tsev nyob. Lub micro hloov siv lub laub khawm thiab lub caij nplooj ntoo hlav tsim.
Txawm hais tias cov engineers tab tom nrhiav qhov ntsuas cua sov rau cov cua sov hauv tsev lossis kev tswj hwm kev lag luam boiler, lossis rau kev hloov qib hauv cov roj tsheb loj, muaj tsib yam tseem ceeb los xav txog: daim ntawv tawm, kev siv hluav taws xob (qhov hluav taws xob / hluav taws xob), kev ntseeg tau (lub tshuab hluav taws xob / hluav taws xob lub neej) , ib puag ncig cov khoom siv (ib puag ncig muaj kev nyab xeeb, qhov kub thiab txias) thiab ntawv pov thawj lub koom haum. Cov kauj ruam tsib hauv qab no yuav pab koj xaiv lub microswitch rau koj daim ntawv thov tshwj xeeb.
Lub chaw tsim hluav taws xob micro hloov kom peb nco tias qhov loj yog qhov tseem ceeb thaum xaiv lub micro hloov. Kev hloov pauv qhov loj yog ncaj qha rau nws cov yam ntxwv, suav nrog cov thaj tsam tam sim no, kev ncig thiab kev khiav hauj lwm. Piv txwv, microswitch tsawg tshaj plaws ntawm kev ua lag luam niaj hnub no yog 0.50" x 0.236" x 0.197" (LxWxH). Txawm hais tias no micro
Lub pob hluav taws xob me me yog tsim nyog rau kev txheeb xyuas cov kev mob hauv Circuit Court hauv kev sib txig ntawm lub tshuab hluav taws xob, tab sis nws feem ntau tsuas yog tawg tam sim no ntawm 0.1 mus rau 3 amps (A) thiab muaj mob stroke luv.
Cov ntawv thov uas xav tau ntau dua tam sim no feem ntau yuav tsum muaj qhov hloov loj dua. Piv txwv, hauv daim ntawv thov roj tank, lub tog raj kheej rau kuaj kom paub txog qib ua kua yuav tsum muaj peev xwm muab tau cov roj teeb loj thiab tiv taus qhov tam sim no loj. Feem ntau hauv kev ua tiav qib kua hloov, qhov hloov hloov ncaj qha tsav lub twj tso kua mis thiab nqa lub loj tam sim no. Qhov no yuav tsum tau siv hluav taws xob rated
Cov tshuab nqus loj loj nrog 20A lossis 25A ntws ntawm 125VAC lossis 250VAC.
Hint: Qhov hloov me me loj dua, qhov me dua lub stroke thiab qhov tam sim no tuaj yeem tawg.
Tsis tas li ntawd, qhov ntev sab nraud ntawm qhov hloov kuj tseem cuam tshuam rau lub zog ua haujlwm. Qhov zoo tshaj plaws, dab tsi cov engineers xav tau yog kev hloov nrog cov khiav hauj lwm qis thiab kev muaj peev xwm tam sim no. Tab sis qhov tseeb muaj qhov hloov-tawm ntawm ob qho no. Tswj qhov sib cuag tau zoo thaum muab kev kam rau siab tam sim no, fretting
Lub pob hloov yuav tsum muaj lub zog nyob rau lub caij nplooj ntoo hlav, uas yuav ua rau kom txoj haujlwm loj thiab tag nrho qhov loj ntawm lub hloov. Kev siv lub zog ua haujlwm thaj tsam li ntawm 2 gram hauv kev siv hluav taws xob pneumatic mus rau 8 ooj nyob rau hauv cov ntawv thov solenoid (uas yuav tsum muaj ntau zog ua haujlwm). Qhov hloov loj tshaj plaws rau ntawm kev ua lag luam yog 1.94" x 0.69" x 1.3"
Nti (LxWxH).
Cov kws tsim choj yuav tsum paub txog qhov sib txawv ntawm kev mus ncig ntawm qhov chaw hloov chaw - qhov kev ncua deb ntawm kev hloov chaw mus ncig thiab txoj haujlwm pib dua. Qhov pib txiav txim yuav sib txawv raws li daim ntawv thov. Piv txwv li, hauv daim ntawv thov kev hloov kub, qhov qhib / tua haujlwm yuav tsum ua kom ze li sai tau, thiab qhov sib txawv ntawm qhov sib txawv yuav tsum tsawg li 0.0001 nti. Tab sis nyob rau theem ua kua theem kev thov tso
Yog tias qhov txawv txav txawv heev, nws yuav ua rau lub twj tso kua mis pib thiab nres ntau dhau, ua lub sijhawm ua haujlwm luv luv ntawm lub twj tso kua mis.
