Qhib lub hwj chim hloov ntawm lub thawv tswj ntawm Cummins generator teeb. Thaum muaj ob lub suab nrawm, nkig thiab me me, lub kaw lus tswj ceev yog qhov qub; Yog tias tsis muaj suab nrov, nws yuav yog tias lub rooj tsav xwm tswj ceev tsis muaj qhov tso tawm lossis lub actuator yog xeb thiab daig.
(1) Kev kuaj xyuas tsis raug ntawm pawg tswj hwm
Thaum lub hwj chim hloov, ntsuas qhov DC voltage ntawm a23-a22 ntawm lub phaj loj. Yog tias qhov hluav taws xob siab tshaj 12V, nws qhia tau tias qhov tso tawm ntawm lub rooj tsav xwm tswj tau zoo li qub. Yog tias u = 0, ntsuas qhov voltage ntawm cov ntsiab lus B thiab C ntawm lub qhov (socket) ntawm lub rooj tsavxwm ceev. Yog tias koj> 12V, lub rooj tsavxwm tswj yog qhov qub. Xyuas seb qhov luam tawm ntawm lub hauv paus phaj loj yog qhib; Txwv tsis pub, yog tias lub rooj tsav xwm tswj ceev tsis ua haujlwm, hloov lub rooj tsav xwm tswj.
(2) Kev tshawb nrhiav tsis raug ntawm tus actuator
Lub coil tsis kam ntawm tus actuator yog 7-loq thiab inductance yog 120mh. Nws yog insulated los ntawm hauv av. Cov teeb meem hluav taws xob tuaj yeem raug txiav txim los ntawm kev ntsuas zoo li qub ntawm ntau yam tsis muaj; Thaum nws yog ib qho nyuaj rau kev txiav txim rau cov neeg kho tshuab qhov teeb meem ntawm kev khiav hauj lwm teeb, ib tug sab nraud 12V ncaj qha fais fab mov tuaj yeem txuas nrog, uas tuaj yeem txiav txim los ntawm lub suab thaum nws qhib thiab tawm. Thaum daim npav thaiv thiab xeb, lub actuator tuaj yeem raug tshem tawm nrog cov cuab yeej tshwj xeeb rau kev ntxuav thiab sib tsoo (hlau abrasive tsis tso cai) rau kev kho. Thaum kho tsis tau, nws yuav tsum tau hloov.
Thaum lub rooj tsavxwm tswj tsis tuaj yeem tswj qhov kev tso tawm ib txwm tawm ntawm kev tswj, nws yog tshwm sim los ntawm cov roj to vim hnav thiab nce kev tshem tawm ntawm tus actuator. Thaum lub idle ceev yog teem rau n < 600r / min thiab qhov ceev nce mus rau 900-l700r / min, nws yog feem ntau hu ua tsis muaj idle speed. Thaum lub teeb khiav lub xeev yog n = l500r / los nag, qhov tseeb ceev yog qis dua l700r / min thiab cov kev tswj ceev tsis raug, uas yog tshwm sim los ntawm cov laj thawj saum toj no. Vim tias lub tshuab hluav taws xob diesel teeb ua haujlwm li ntawm l500r / los nag, qhov nrawm nrawm tsis muaj qhov cuam tshuam me ntsis, thiab cov actuator tuaj yeem siv txuas ntxiv mus; Thaum cov roj to yog qhov hnyav thiab qhov ceev yog siab dhau, tab sis thaum thauj khoom Lo% - L5%, qhov ceev poob tuaj yeem ncav cuag lub xeev tswj, thiab cov actuator tseem tuaj yeem siv txuas ntxiv mus; Yog tias qhov ceev nce ntau kom txog thaum nws nres vim kev tiv thaiv overspeed, hloov lub actuator.
(3) Kev soj ntsuam ceev sensor
Thaum lub teeb liab ntawm qhov ceev sensor muaj zog heev, qhov ceev ntawm qhov ceev tswj qhov system tsis ruaj khov. Thaum lub teeb liab tsis muaj zog heev thiab tsis muaj teeb liab, nws yooj yim los tswj tsis ua hauj lwm thiab ua rau overspeed. Lub coil tsis kam ntawm qhov ceev sensor yog li 300 Ω, thiab cov zis voltage yog 1.5-20vac thaum ua haujlwm. Txwv tsis pub, lub sensor yuav tsum tau hloov thaum muaj teeb meem. Kev kho ntawm lub teeb liab ceev lub zog ntawm kev ceev sensor: ntsia hlau lub sensor nyob rau hauv, nruj lub iav kawg 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 cov hniav yog hais txog 0.7mm-1.1mm. Lub spin nyob rau hauv cov zis voltage nce thiab lub spin output voltage txo.
