Inzwa yokucindezela yezingxenye zenjini ye-Cummins Volvo 4921473

Yiziphi izinkinga zephutha zenzwa yokucindezela?

1. Izimpumelelo zokuvala indandatho yenzwa yokucindezela

Okokufaka kwe-pressure transmitter akushintshi, bese okokufaka kwe-pressure transmitter kushintsha ngokuzumayo, futhi indawo ye-zero yesidlulisi sokucindezela ayikwazi ukubuyela emuva, okungenzeka kube umphumela wendandatho yokuvala inzwa yokucindezela. Akuvamile ukuthi indandatho yokuvala icindezelwe ngaphandle kwendawo yokungena yokucindezela kwenzwa ngemva kokuba inzwa iqinisiwe, nendawo yokucindezela ayikwazi ukungena lapho icindezelwa, kodwa uma umfutho uphakeme, indandatho yokuvala ivele iphushwe ivuleke. futhi inzwa yokucindezela iyashintshwa. Indlela enhle yokuqeda lolu hlobo lwenkinga ukukhipha inzwa bese ubheka ngokungaqondile ukuthi indawo eyiziro ayijwayelekile yini. Uma kunguziro,

2. Iphutha lokuqhathanisa phakathi kwe-transmitter ne-pointer pressure gauge likhulu.

Iphutha lephrezentheshini liwuphawu lokungajwayelekile, ngakho kwanele ukuqinisekisa isikali sephutha sokungajwayelekile; Okokugcina, iphutha elitholakala kalula liwumphumela wokuma kwe-micro-differential pressure transmitter kokokufaka okunguziro. Ngenxa yesikali sayo esincane sokulinganisa, izakhi zenzwa ku-micro-differential pressure transmitter zizothinta okokufaka kwe-micro-differential pressure transmitter. Lapho ufaka, inzwa yokucindezela yesidluliseli kufanele icheme mpo kumandla adonsela phansi, futhi indawo eyiziro yesidluliseli kufanele ilungiswe ibe nenani elijwayelekile ngemva kokuba idivayisi isiqinile.

3, ingcindezi iphansi, okokufaka kwe-transmitter akukwazanga ukuvuleka.

Kulesi simo, kufanele siqale sicabange ukuthi isixhumi esibonakalayo sengcindezi singavuza noma sivinjwe. Uma kungenjalo, kufanele sicabange ngendlela yezintambo kanye nokunikezwa kwamandla. Uma ukunikezwa kwamandla kungavamile, kufanele siyeke ukucindezela kafushane ukuze sibone ukuthi okokufaka kungashintshwa yini. Mhlawumbe kufanele sibheke ukuthi indawo eyiziro yenzwa ingaba nakho okokufaka. Uma lungekho ushintsho, inzwa ibhujisiwe, okungaba ukucekelwa phansi kwensimbi noma zonke ezinye izimpumelelo ezibalulekile zalo lonke uhlelo.

4. Isignali yokufaka yesidluliseli ayizinzile

Lolu hlobo lwephutha luwumphumela womthombo wengcindezi. Umthombo wokucindezela ngokwawo uwukucindezela okungazinzile, futhi kungenzeka ukuthi ikhono lokulwa nokuphazamiseka kwensimbi noma inzwa yokucindezela alinamandla, inzwa ngokwayo idlidliza ngokunamandla futhi inzwa inephutha;
