Isivamvo soxinzelelo lweCummins iinxalenye zenjini yeVolvo 4921473

Ziziphi iingxaki eziphosakeleyo zenzwa yoxinzelelo?

1. Impumelelo yokutywina inzwa yokutywina

Igalelo le-pressure transmitter ayitshintshi, kwaye emva koko igalelo le-pressure transmitter litshintsha ngokukhawuleza, kwaye indawo ye-zero ye-pressure transmitter ayikwazi ukubuyela emva, mhlawumbi isiphumo sokutywinwa kweseva yoxinzelelo.Kunqabile ukuba umsesane wokutywina ucinezelwe ukuya ngaphandle kwe-sensor yoxinzelelo lwenzwa emva kokuba i-sensor iqinisiwe, kwaye i-pressure medium ayikwazi ukungena xa ixinzelelwe, kodwa xa uxinzelelo luphezulu, ikhonkco lokutywinwa ngokukhawuleza lityhilwe livuleke. kwaye inzwa yoxinzelelo iyatshintshwa.Indlela efanelekileyo yokuphelisa olu hlobo lwengxaki kukususa inzwa kunye nokujonga ngokungathanga ngqo ukuba indawo ye-zero ayiqhelekanga.Ukuba ngu-zero,

2. Impazamo yokuthelekisa phakathi kwe-transmitter kunye ne-pointer pressure gauge inkulu.

Impazamo yonikezelo luphawu lokungaqhelekanga, ngoko kwanele ukuqinisekisa isikali sempazamo yokungaqhelekanga;Okokugqibela, impazamo ekulula ukuyiveza yimpembelelo yendawo ye-micro-differential pressure transmitter kwigalelo elingu-zero.Ngenxa yomlinganiselo omncinci wokulinganisa, izinto zenzwa kwi-micro-differential pressure transmitter ziyakuchaphazela igalelo le-micro-differential pressure transmitter.Xa ufaka, inzwa yoxinzelelo lwe-transmitter kufuneka ihlawulwe ngokuthe nkqo kwi-gravity, kwaye indawo ye-zero ye-transmitter kufuneka ilungiswe kwixabiso eliqhelekileyo emva kokuba isixhobo siqinile.

3, uxinzelelo luphantsi, igalelo lokuhambisa alikwazanga ukuqhubekeka.

Kule meko, kufuneka siqale sicinge malunga nokuba i-interface yoxinzelelo inokuvuza okanye ivalwe.Ukuba akunjalo, kufuneka sibonise indlela yocingo kunye nokunikezelwa kwamandla.Ukuba unikezelo lwamandla aluqhelekanga, kufuneka siyeke ukucinezela ngokufutshane ukubona ukuba igalelo lingatshintshwa.Mhlawumbi kufuneka siqwalasele ukuba indawo ye-zero yoluvo ingaba negalelo.Ukuba akukho tshintsho, inzwa iye yatshatyalaliswa, enokuthi ibe yinto yokutshatyalaliswa kwesixhobo okanye ezinye iimpumelelo eziphambili zenkqubo yonke.

4. Isignali yegalelo ye-transmitter ayizinzile

Olu hlobo lwesiphoso luyisiphumo somthombo woxinzelelo.Umthombo woxinzelelo ngokwawo nguxinzelelo olungazinzanga, kwaye kunokwenzeka ukuba ikhono lokuchasana nokuphazamiseka kwesixhobo okanye inzwa yoxinzelelo ayinamandla, inzwa ngokwayo iduduza ngokukrakra kwaye inzwa iphosakele;
