Inzwa yokucindezela kawoyela ilungele injini ye-Cummins 4088734

1, isetshenziswa ohlelweni lwe-hydraulic

Inzwa yokucindezela isetshenziswa kakhulu ukuqedela ukulawulwa kwe-loop evaliwe ohlelweni lwe-hydraulic. Lapho i-spool ye-valve yokulawula ihamba ngokuzumayo, ingcindezi ephakeme izikhathi eziningana ingcindezi yokusebenza yesistimu izokwakhiwa ngesikhathi esifushane kakhulu. Emishinini ephathwayo ejwayelekile kanye nezinhlelo ze-hydraulic zezimboni, uma izimo zokusebenza ezimbi kangako zinganakwa ekwakhiweni, noma iyiphi inzwa yokucindezela izobhujiswa maduze. Kuyadingeka ukusebenzisa inzwa yokucindezela engazweli. Kunezindlela ezimbili eziyinhloko zenzwa yokucindezela ukuze kuzuzwe ukumelana nomthelela, enye iwukushintsha i-chip yohlobo lwe-strain, kanti enye iwukuxhuma ishubhu lediski ngaphandle. Ngokuvamile, indlela yokuqala yamukelwa ohlelweni lwe-hydraulic, ikakhulukazi ngoba kulula ukuyifaka. Ngaphezu kwalokho, esinye isizathu ukuthi inzwa yokucindezela kufanele ithwale ukucindezela okungaphazamiseki kwe-pulsation kusuka kupompo ye-hydraulic.

2. Kusetshenziswa ohlelweni lokulawula ukuphepha

Izinzwa zokucindezela zivame ukusetshenziswa ezinhlelweni zokulawula ukuphepha, ikakhulukazi ezihloswe ohlelweni lokulawula ukuphepha kwama-compressor emoyeni. Kunezinhlelo zokusebenza eziningi zezinzwa emkhakheni wokulawula ukuphepha, futhi akumangazi ukuthi inzwa yokucindezela, njengenzwa evamile kakhulu, isetshenziswa ohlelweni lokulawula ukuphepha.

Isicelo emkhakheni wokulawula ukuphepha ngokuvamile sibhekwa kusukela ezicini zokusebenza, intengo kanye nokuphepha kanye nokuba lula kokusebenza kwangempela. Kufakazelwa ukuthi umphumela wokukhetha inzwa yokucindezela muhle kakhulu. Inzwa yokucindezela isebenzisa ubuchwepheshe bokucutshungulwa kwezinto zokusebenza ukuze ifake izingxenye ezithile nezilawuli zesignali ku-chip encane. Ngakho usayizi wayo omncane futhi ungenye yezinzuzo zayo. Ngaphandle kwalokho, intengo yayo ephansi ingenye inzuzo enkulu. Ngokwezinga elithile, ingathuthukisa ukunemba kokuhlolwa kwesistimu. Ohlelweni lokulawula ukuphepha, kuyisilinganiso esithile sokuvikela kanye nesistimu yokulawula esebenza kahle kakhulu yokulawula ingcindezi elethwa i-compressor ngezinga elithile ngokufaka inzwa yokucindezela emishinini yamapayipi endaweni yokuphuma komoya. Lapho i-compressor iqala ngokujwayelekile, uma inani lokucindezela lingafinyeleli umkhawulo ophezulu, isilawuli sizovula i-air inlet futhi siyilungise ukuze senze imishini ifinyelele amandla amakhulu.
