Tig rau lub hwj chim hloov ntawm lub thawv tswj ntawm Cummins Generator teeb. Thaum muaj ob lub nrawm, crisp thiab cov suab me me, cov tswj kev ceev yog qhov qub; Yog tias tsis muaj lub suab, nws yuav yog tias tus tswj hwm kev tswj hwm ceev tsis muaj kev tsim tawm lossis cov actuator yog xeb thiab daig.
(1) Txhaum Nrhiav kom muaj kev tswj hwm
Thaum lub hwj chim hloov yog nyob rau, ntsuas lub DC voltage ntawm A23-A22 ntawm lub xov hlau loj. Yog hais tias tus qauv hluav taws xob siab dua 12v, nws qhia tau tias cov zis ntawm cov tswj hwm yog qhov qub. Yog tias koj = 0, ntsuas qhov hluav taws xob ntawm cov ntsiab lus B thiab C ntawm lub qhov (socket) ntawm cov tswj hwm ceev. Yog U> 12v, tswj hwm lub rooj tsavxwm yog ib txwm muaj. Kuaj seb cov luam tawm Circuit Court ntawm lub xov tooj loj qhib; Txwv tsis pub, yog tias cov tswj hwm ceev tsis tau, hloov cov tswj hwm.
(2) Txhaum Nrhiav tau ntawm Actuator
Lub coil resistance ntawm actuator yog 7-loq thiab inductance yog 120mh. Nws yog insulated los ntawm hauv av. Hluav taws xob muaj peev xwm raug txiav txim los ntawm kev ntsuas zoo li qub ntawm ntau yam tsis muaj ntau; Thaum nws nyuaj rau kev txiav txim rau cov tshuab kev ua haujlwm ntawm cov kev ua haujlwm tsim, yog ib qho kev ua haujlwm sab nraud ua haujlwm tuaj yeem sib txuas, uas tuaj yeem raug txiav txim thaum nws nyob ntawm thiab tawm. Thaum daim npav thaiv thiab xeb, tus actuator tuaj yeem raug tshem tawm nrog cov cuab yeej tshwj xeeb rau kev ntxuav thiab sib tsoo (cov abrasive tsis raug tso cai) rau kev kho. Thaum nws tsis tuaj yeem kho, nws yuav tsum tau hloov.
Thaum cov tswj hwm tswj tau tsis tswj hwm qhov tso zis tsis zoo tawm ntawm kev tswj hwm, nws tshwm sim los ntawm cov roj xau vim hnav thiab nce kev tshem tawm ntawm cov actuator. Thaum lub kaw lus ceev yog teeb nyob rau ntawm n <900r / min thiab cov ceev nce mus rau 900-L700R / min, nws feem ntau yog hu ua tsis muaj kaw ceev. Thaum lub sijhawm khiav khiav yog n = L500r / nag, qhov ceev nrawm yog hauv qab l700r / min thiab cov kev cai ceev tsis yog qhov tsis raug, uas yog tshwm sim los ntawm cov laj thawj saum toj no. Vim hais tias cov diesel lub tshuab hluav taws xob teeb tsa ua haujlwm ntawm L500R / Nag, lub suab kaw muaj cov nyhuv me me, thiab cov actuator tuaj yeem siv txuas ntxiv; Thaum cov roj xau yog qhov hnyav thiab nrawm yog dhau, tab sis thaum thauj khoom LE% - L5%, qhov nrawm nrawm tuaj yeem ncav cuag cov khoom siv ib txwm muaj; Yog tias qhov nrawm nce ntau heev kom txog thaum nws nres vim nws kev tiv thaiv kev tiv thaiv dhau los, hloov cov actuator.
(3) Nrhiav kom ceev ntawm Sensor
Thaum lub teeb liab ntawm lub nrawm nrawm yog muaj zog heev, qhov ceev ntawm kev tswj hwm ceev ceev tsis ruaj khov. Thaum lub teeb liab tsis muaj zog heev thiab tsis muaj teeb liab, nws yog qhov yooj yim los tswj tsis ua haujlwm thiab ua rau kev saib xyuas. Lub coil resistance ntawm cov ceev sensor yog li 300 ω, thiab cov zis hluav taws xob yog 1.5-20vac thaum lub sijhawm ua haujlwm. Txwv tsis pub, lub sensor yuav tsum tau hloov thaum txhaum. Kho kom haum ntawm lub teeb pom kev nrawm nrawm ntawm cov ceev sensor: zawm lub iav xaus ntawm flywheel, ces tawm rau 1 / 2-3 / 4 tig thiab xauv nws. Nyob rau lub sijhawm no, qhov sib txawv ntawm sab saum toj ntawm lub sensor thiab flywheel hniav cov ntsis yog li 0.7mm-1.1mm. Tus kiv hauv cov zis voltage nce thiab cov kiv tawm output voltage txo qis.
