I-RE542461 isetyenziselwa inzwa yoxinzelelo lweoyile kaJohn Deere.

Iinzwa zokulawula injini

Kukho iintlobo ezininzi zezivamvo zokulawula injini, kubandakanywa isivamvo sobushushu, isivamvo soxinzelelo, isantya kunye nesivamvo se-angle, isivamvo sokuqukuqela, isivamvo sendawo, isivamvo sokuxinana kwegesi, isivamvo sokunkqonkqoza njalo njalo.Olu hlobo loluvo lungundoqo we-injini yonke.Ukuzisebenzisa kunokuphucula amandla e-injini, ukunciphisa ukusetyenziswa kwepetroli, ukunciphisa igesi yokukhupha, ukubonisa iimpazamo, njl. Ngenxa yokuba basebenza kwiimeko ezinzima ezifana ne-injini ye-vibration, umphunga wepetroli, i-sludge kunye namanzi anodaka, isalathiso sabo sobugcisa bokumelana nokusingqongileyo siphezulu kunoko. leyo yezivamvo eziqhelekileyo.Kukho iimfuno ezininzi kwiimpawu zabo zokusebenza, phakathi kwazo eyona nto ibaluleke kakhulu kukuchaneka komlinganiselo kunye nokuthembeka, ngaphandle koko impazamo ebangelwa ukufumanisa inzwa ekugqibeleni iya kukhokelela ekungaphumeleli kwenkqubo yokulawula injini okanye ukungaphumeleli.

1. Uluvo lobushushu:

Ibona ubukhulu becala ubushushu be-injini, ubushushu berhasi yokungena, ubushushu bamanzi okupholisa, ubushushu be-oyile ye-oyile, ubushushu be-oyile ye-injini, ubushushu be-catalytic, njl.Isivamvo sobushushu sokumelana nenxeba sinokuchaneka okuphezulu, kodwa iimpawu zokusabela ezimbi;Inzwa ye-Thermistor inovelwano oluphezulu kunye neempawu zokuphendula ezilungileyo, kodwa umgca ombi kunye nobushushu obuphantsi obusebenzayo.Uhlobo lwe-Thermocouple luchaneke kakhulu kunye noluhlu olubanzi lokulinganisa ubushushu, kodwa iamplifier kunye nonyango olubandayo kufuneka luthathelwe ingqalelo.

2. Isivamvo soxinzelelo:

Ibona ubukhulu becala uxinzelelo olupheleleyo lokuthatha okuninzi, isidanga sevacuum, uxinzelelo lwe-atmospheric, uxinzelelo lweoyile ye-injini, uxinzelelo lweoyile yebrake, uxinzelelo lwetayara, njl.njl. Kukho iintlobo ezininzi zezivamvo zoxinzelelo lwesithuthi, phakathi kwazo i-capacitive, piezoresistive, inductance variable eqhutywa yi-diaphragm (LVDT). ) kunye ne-surface elastic wave (SAW) zisetyenziswa ngokubanzi.I-sensor ye-Capacitive ineempawu zamandla aphezulu, impendulo eguquguqukayo kunye nokuguquguquka okuhle kokusingqongileyo.I-varistor ithonywe kakhulu yiqondo lokushisa, ngoko kufuneka iseke isiphaluka sembuyekezo yeqondo lokushisa, kodwa ifanelekile kwimveliso yobuninzi.Uhlobo lwe-LVDT lunemveliso enkulu, elula kwimveliso yedijithali, kodwa ukuxhathisa ukungcangcazela akubi;I-SAW iyinzwa efanelekileyo ngenxa yobukhulu bayo obuncinci, ubunzima bokukhanya, ukusetyenziswa kwamandla aphantsi, ukuthembeka okuqinileyo, uvakalelo oluphezulu, isisombululo esiphezulu kunye nemveliso yedijithali.
