I-Pressure Sensor 17216318 ilungele iVolvo Roller / Grader

Lapho ukhetha inzwa efanele, izinhlobo ezahlukene zemishini kanye nabalawuli abahlelekile badinga ukunaka imininingwane. Cishe wonke umshini wanamuhla odinga ukulungiswa noma ukuthuthukiswa kunezidingo ezikhethekile zezinhlobo zedatha okufanele zitholakale. Hhayi kuphela umshini onezidingo ezithile, kepha futhi ne-CPU nemodyuli yohlelo lokulawula banezidingo zabo.

Ngenxa yalokhu kwehlukahlukana, kunezinzwa ezinhlobonhlobo ezitholakalayo, futhi inzwa ngayinye yenzelwe umsebenzi othize futhi ihlinzeka ngokucushwa kwedatha ethile. Kuleli phepha, inqubo yokukhetha inzwa efanelekile yezinhlelo zokusebenza ezihlukile izofundwa ngokucophelela. Ikakhulu, ulwazi oluyisisekelo lokusebenzisa amapharamitha womshini ukuthola uhlobo lwenzwa okufanele lukhethwe, nokuthi luzokhetha kanjani phakathi kwezindawo ezivamile ezivulekele futhi zivame ukuvalwa.

Izinhlobo ezahlukene zezigaba zezinzwa

Ubudlelwano phakathi komkhiqizo ozama ukuthola futhi ukukhetha kwenzwa kubaluleke kakhulu kunanoma yini enye. Imvamisa, uma uthola ukuthi wenze isinqumo esingalungile kulezi zinto, ungathola indlela yokuhlela noma imodyuli yokuguqula ubukhosi besiginali.

Kodwa-ke, uma kukhethwe isigaba esingalungile sezinzwa, umkhiqizo kungenzeka ungatholwa nhlobo. Alikho inani lemibuthano elingaxazulula le nkinga.

I-Sensor Polarity

Okufakwayo okuningi kwedijithali kudinga ukuxhunywa ku-DC Voltage, imvamisa ku-10 vdc. Kodwa-ke, ezinye izinhlelo zingasebenzisa i-vacthan engu-120 noma kwesinye isikhathi ezingama-24 Vacunt Voltage. Lezi zinzuzo kwamanye amacala akhethekile, ngoba azidingi ubunzima be-DC Power Supply futhi badinga kuphela i-transformer.

Lezi zinzwa ze-AC zivame ukusethwa nge-polarity, futhi amashidi wedatha avame ukukhombisa ukuthi imithwalo ingabekwa ezintanjeni ezishisayo noma izintambo ezingathathi hlangothi, ezivame ukunsundu futhi ziluhlaza okwesibhakabhaka kusuka kumahhanisi womsila wangaphambi.

Inzwa ye-AC kufanele ikhethwe kuphela lapho imodyuli yokufaka yesilawuli ilungiselelwe njenge-AC. Lokhu akujwayelekile njenge-DC, kepha lolu hlobo kufanele lusetshenziswe uma imodyuli yenzelwe ukufakwa kwe-vaft okungu-120.

Imvamisa evulekile noma evame ukuvalwa

Omunye umehluko ezinqumweni zokukhetha ze-sensor ukukhetha phakathi kokuvula okujwayelekile (cha) futhi kuvalwe ngokujwayelekile (NC). Ngaphakathi kwesilinganiso sohlelo lokulawula iDijithali, akuwenzi mehluko, inqobo nje uma uhlelo lubhalelwe inzwa efanele.

Umehluko kuphela we-NO / NC ukuthi uma uhlobo lwezinzwa lukhethwe ukwenza umjikelezo wenzwa uvule ngaphezu kwe-50% yempilo yawo, kungagcina amandla. Ukonga izindleko kungaba mncane, kepha lapho izindleko zokuqala zenzwa ziyefana, kunenjongo ukukhetha imishini esebenza kahle kakhulu yokwakheka.
