Umgomo wokusebenza we-excavator pressure sensor kanye ne-pressure switch

I-Excavator Pressure Sensor

Inzwa yokucindezela kwe-Komatsu iboniswa ku-Figure 4-20.Lapho uwoyela ungena endaweni yokucindezela futhi ingcindezi isetshenziswa ku-diaphragm yesitshina sokucindezela kwamafutha, i-diaphragm iyagoba futhi ikhubazekile.Isendlalelo sokulinganisa sibekwe ngakolunye uhlangothi lwe-diaphragm, futhi inani lokumelana lesendlalelo sokulinganisa liyashintsha, liguqule ukugoba kwe-diaphragm ibe i-voltage ephumayo, edluliselwa ku-amplifier kagesi, ebuye ikhulise amandla kagesi, okuyi-voltage. bese idluliselwa kusilawuli se-electro-mechanical (ibhodi lekhompyutha).

Umfanekiso 4-20

Ukuphakama kwengcindezi ku-sensor, ukuphakama kwe-voltage ephumayo;ngokusho kwengcindezi yokuzwa, inzwa yokucindezela ivame ukuhlukaniswa ngezinhlobo ezimbili: inzwa yokucindezela okukhulu kanye nenzwa yokucindezela okuphansi.Inzwa yokucindezela okuphezulu isetshenziselwa ukukala ingcindezi yokukhipha kanye nokucindezela komthwalo wepompo eyinhloko.Izinzwa zokucindezela okuphansi zisetshenziswa ezinhlelweni zokulawula umshayeli kanye nezinhlelo zokubuyisela uwoyela.

Ama-voltage avamile okusebenza ezinzwa zokucindezela yi-5V, 9V, 24V, njll. (ukunaka okukhethekile kufanele kukhokhwe ukuze kuhlukaniswe uma kufakwa esikhundleni).Ngokuvamile, izinzwa zokucindezela emshinini ofanayo zisebenza ku-voltage efanayo.Ukusebenza kwamanje kwenzwa yokucindezela kuncane kakhulu, futhi kunikwe amandla ngokuqondile ibhodi lekhompyutha.

I-Excavator Pressure Switch

Ukushintsha kwengcindezi kuboniswa kuMfanekiso 4-21.I-pressure switch ithola isimo sokucindezela (ukuvula/ukuvala) kwesekethe yomshayeli bese iyidlulisela ebhodini lekhompyutha.Kunezinhlobo ezimbili zokushintsha kwengcindezi: ngokuvamile kuvalwe futhi kuvame ukuvaleka, kuye ngokuthi isifunda sixhunyiwe uma kungekho ngcindezi ethekwini.Amamodeli ahlukene nezingxenye ezihlukene zokushintsha kwengcindezi zinezingcindezi ezihlukene zokusebenzisa kanye nezingcindezi zokusetha kabusha.Ngokuvamile, amaswishi okucindezela emishini ejikelezayo neyomsebenzi anezingcindezi eziphansi zokuqalisa, kuyilapho amaswishi okucindezela ukuhamba anengcindezi ephezulu yokuqalisa.
