I-Pressure switch 7861-93-1880 yenzwa yokucindezela izingxenye ze-excavator

Amaphutha ajwayelekile

Ukwehluleka kwezinzwa zokucindezela ikakhulukazi kungokulandelayo:

Okokuqala ukuthi ingcindezi iyakhuphuka, kodwa i-transmitter ayikwazi ukukhuphuka. Kulokhu, qala uhlole ukuthi isixhumi esibonakalayo sokucindezela siyavuza noma sivinjiwe. Uma kungenjalo, hlola imodi yezintambo kanye nokunikezwa kwamandla. Uma ukunikezwa kwamandla kujwayelekile, vele ukucindezele ukuze ubone ukuthi okukhiphayo kuyashintsha yini, noma uhlole ukuthi indawo eyiziro yenzwa inokukhiphayo. Uma lungekho ushintsho, inzwa yonakele, okungenzeka kube inkinga yokulimala kwensimbi noma ezinye izixhumanisi zesistimu yonke.

Okwesibili ukuthi ukukhishwa kwe-pressurization transmitter akushintshi, bese ukukhishwa kwe-pressurization transmitter kushintsha ngokuzumayo, ukuze indawo ye-zero ye-transmitter yokunciphisa ingcindezi ingakwazi ukubuyiselwa, okungenzeka ukuthi inkinga ye-sensor sensor sealing ring. . Kuvamile ukuthi ngenxa yokucaciswa kwendandatho yokuvala, ngemva kokuba inzwa iqinisiwe, indandatho yokuvala igxiliwe ekungeneni kokucindezela kwenzwa ukuze kuvinjwe inzwa, futhi umshini wokucindezela awukwazi ukungena lapho ucindezelwa, kodwa lapho ukucindezela kuphezulu, indandatho yokuvala ivele ivuleke, futhi inzwa yokucindezela ishintsha ngaphansi kwengcindezi. Indlela engcono kakhulu yokuqeda leli phutha ukukhipha inzwa futhi uhlole ngokuqondile ukuthi indawo ye-zero ijwayelekile yini. Uma indawo eyiziro ijwayelekile, buyisela iringi yokuvala bese uzama futhi.

Okwesithathu ukuthi isignali yokuphuma kwe-transmitter ayizinzile. Lolu hlobo lwephutha lungaba inkinga yomthombo wengcindezi. Umthombo wokucindezela ngokwawo ukucindezela okungazinzile, okungenzeka kungenxa yekhono elibuthakathaka lokulwa nokuphazamiseka kwensimbi noma inzwa yokucindezela, ukudlidliza okuqinile kwenzwa ngokwayo kanye nokwehluleka kwenzwa; Okwesine ukuthi umehluko phakathi kwe-transmitter ne-pointer pressure gauge mkhulu. Ukuchezuka kujwayelekile, vele uqinisekise uhla lokuchezuka olujwayelekile;

Iphutha lokugcina elivamile umthelela wendawo yokufaka yesidlulisi somfutho omncane ohlukanisiwe ekuphumeni kweqanda. Ngenxa yobubanzi bayo obuncane bokulinganisa, izakhi zokuzwa ku-micro differential pressure transmitter zizothinta ukuphuma kwesidlulisi somfutho we-micro differential. Ngesikhathi sokufakwa, ingxenye ezwela ukucindezela yesidluliseli kufanele ibe nge-axially perpendicular iqonde lapho kuqondiswa khona amandla adonsela phansi, futhi indawo eyiziro yesidluliseli kufanele ilungiswe ibe ivelu elijwayelekile ngemva kokufakwa nokulungiswa.
