Ifanelekile kwiCummins QSK38 inzwa yoxinzelelo 3408600

Iimpazamo ezine eziqhelekileyo zeSensom yoxinzelelo

1. Iingxaki zokutywinwa kweringi ye-pressure transmitter

Emva koxinzelelo lokuqala, imveliso ye-transmitter ayizange itshintshe, kwaye emva koko imveliso ye-transmitter yatshintsha ngokukhawuleza, kwaye indawo ye-zero ye-transmitter ayikwazanga ukubuyela emva emva kokukhululeka koxinzelelo, ekusenokwenzeka ukuba yingxaki yeringi yokutywina isivamvo soxinzelelo. Imeko eqhelekileyo kukuba ngenxa yeenkcukacha zendandatho yokutywina, ikhonkco yokutywina ixinzelelwe kwi-inlet yoxinzelelo lwenzwa emva kokuba inzwa iqiniswe, ngaloo ndlela ivalela inzwa. Xa ucinezelekile, i-pressure medium ayikwazi ukungena, kodwa xa uxinzelelo luphezulu, ikhonkco lokutywina ngokukhawuleza ligqabhuka, kwaye inzwa yoxinzelelo iyatshintsha phantsi koxinzelelo. Indlela efanelekileyo yokuphelisa le mpazamo kukususa inzwa kwaye ukhangele ngokuthe ngqo ukuba indawo ye-zero iyinto eqhelekileyo. Ukuba indawo enguziro iqhelekile, buyisela umsesane wokutywina uze uzame kwakhona.

2, uxinzelelo lunokunyuka, kodwa imveliso ye-transmitter ayikwazi ukuphakama.

Kule meko, kufuneka siqale sijonge ukuba ujongano loxinzelelo luyavuza okanye luvalekile. Ukuba iqinisekisiwe, kufuneka sijonge ukuba imo ye-wiring ayilunganga kwaye sijonge ukunikezelwa kwamandla. Ukuba unikezelo lwamandla luqhelekile, kufuneka silucinezele ngokulula ukubona ukuba imveliso itshintshile na okanye indawo ye-zero ye-sensor inemveliso. Ukuba ayitshintshanga, inzwa yonakele. Ngaphandle koko, yingxaki yomonakalo wesixhobo okanye ezinye iikhonkco zenkqubo yonke.

3. Ukutenxa phakathi kwe-transmitter kunye ne-pointer pressure gauge yegeyiji inkulu.

Oku kutenxa kuqhelekile, qinisekisa nje uluhlu oluqhelekileyo lokutenxa; Isiphoso sokugqibela ekulula ukwenzeka yimpembelelo yendawo yokufakela i-micro differential pressure transmitter kwisiphumo se-zero. Ngenxa yoluhlu lwayo oluncinci lokulinganisa, izinto ezizivayo kwi-micro differential pressure transmitter ziyakuchaphazela imveliso ye-micro differential pressure transmitter. Ngexesha lofakelo, indawo ebuthathaka yoxinzelelo lwe-transmitter kufuneka ibe yi-axially 90 degrees perpendicular ukuya kwicala lomxhuzulane. Emva kokufakela kunye nokulungiswa, khumbula ukulungisa indawo ye-zero ye-transmitter kwixabiso eliqhelekileyo.

4. Isignali yemveliso ye-transmitter ayizinzile.

Olu hlobo lwesiphoso ngokuqinisekileyo lunokubangelwa ngumthombo woxinzelelo. Umthombo woxinzelelo ngokwawo luxinzelelo olungazinzanga. Kungenzeka ukuba ikhono lokuchasana nokuphazamiseka kwesixhobo okanye inzwa yoxinzelelo ayinamandla, inzwa ngokwayo ingcangcazela kakubi okanye inzwa yonakaliswe.
