Ukugcinwa kwezinzwa zengcindezi

1. Yini inzwa

Njengamanje, inzwa abantu abayishoyo yakhiwa izingxenye ezimbili: into yokuguqula kanye nento ebucayi. Phakathi kwazo, into eguqulwayo ibhekisa engxenyeni yenzwa eguqula isilinganiso sasizwa noma siphendulwe yinto ebucayi esignalini sikagesi esifanele ukudluliswa noma ukukalwa; Into ebucayi ibhekisa engxenyeni yenzwa engazizwa ngokuqondile noma iphendule engxenyeni.

Njengoba ukuphuma kwenzwa kuvame ukuba yisiginali ebuthakathaka kakhulu, kudinga ukuguqulwa futhi kukhuliswe. Kodwa-ke, ngokuthuthuka okuqhubekayo kwesayensi nezobuchwepheshe, abantu bafake le ngxenye yesekethe umjikelezo kanye nokuphakela amasekethe ndawonye ngaphakathi kwenzwa. Ngale ndlela, inzwa ingakhipha isibonakaliso esisebenzisekayo sokucutshungulwa okulula nokudluliselwa. Esimweni sobuchwepheshe obusemuva emuva esikhathini esidlule, le nzwa ebizwa ngokuthi inzwa ebikade isho into ebucayi, ngenkathi i-Transmitter iyinto yokuguqula.

2. Ungayithola kanjanitransmitter nensor

Izinzwa zivame ukwakhiwa kwezinto ezibucayi kanye nezinto ezibucayi, futhi ziyisikhathi esijwayelekile samadivayisi noma amadivaysi angabona izilinganiso ezicacisiwe futhi aziguqule zibe amasiginali okukhipha asebenzayo ngokuya ngemithetho ethile. Lapho umphumela we-sensor uyisibonakaliso esijwayelekile esichaziwe, kungumdlulisi. Idivayisi eguqula isiginali ngokomzimba ibe yisiginali kagesi ibizwa ngokuthi inzwa, nensimbi eguqula isiginali kagesi engajwayelekile ibe isibonakaliso esijwayelekile kagesi sibizwa ngokuthi isidlulisi. Ithuluzi eliyinhloko libhekisela kwithuluzi lokulinganisa indawo noma imitha yokulawula eyisisekelo, futhi ithuluzi lesibili lisho ukusetshenziswa kwesiginali yemitha eyinhloko ukuqedela eminye imisebenzi.

Ama-Transmitters nezinzwa ndawonye zakha umthombo wesiginali wokuqapha ngokulawulwa okuzenzakalelayo. Izinzwa ezahlukene kanye nama-transmitter ahambisanayo angahlanganiswa ukuze ahlangabezane nezidingo zenani elihlukile lomzimba. Isiginali kagesi esibuthakathaka eqoqwe yi-sensor ikhuliswe yi-transmitter, futhi isiginali ikhuliswe ngokudlulisela noma ukwenza kusebenze kwento yokulawula. Izinzwa ziguqula inani elingalingani kagesi kuzimpawu zikagesi futhi zidlulisele lezi zimpawu ngqo kuma-transmitters. Kukhona futhi ukudlulisela okuthumela amanzi engxenyeni engezansi yezinzwa ezingezansi ze-liquid sensor kanye namanzi ancishisiwe engxenyeni engenhla yomanzi kuqhutshwa yi-pollows yensimbi eshayela nge-pointer yeliveli yamanzi. Ngaphezu kwalokho, kukhona ama-transmitters aguqula inani le-analog kagesi libe amanani edijithali.

Amaphutha amakhulu athambekele ekwenzeni izinzwa zokucindezela nakuma-transmitters anjengokulandelayo: okokuqala ukuthi ingcindezi iyakhuphuka, futhi ukudluliselwa akukwazi ukukhuphuka. Kulokhu, qala uhlole ukuthi itheku lengcindezi liyavuza noma livinjelwe yini. Uma kungaqinisekiswanga, hlola indlela ye-wiring bese uhlola ukunikezwa kwamandla. Uma ukulethwa kwamandla kujwayelekile, mane ucindezele ukubona ukuthi umphumela wokukhipha, noma uhlole ukuthi ngabe kukhona umphumela endaweni ye-zero ye-sensor. Uma kungekho shintsho, inzwa yonakalisiwe, engabangelwa ukulimala kwensimbi noma ezinye izinkinga kulo lonke uhlelo;

Okwesibili ukuthi umphumela wokudluliselwa kwengcindezi akushintshi, futhi umphumela wokudluliselwa kwengcindezi ushintsho kungazelelwe, futhi ingcindezi ikhipha umshushisi we-zero uma kancane kungabuyi emuva, kungenzeka kube yinkinga ngophawu lwezinzwa lwengcindezi.

Imvamisa, ngenxa yokucaciswa kwendandatho yokubopha uphawu, ngemuva kokuthi inzwa iye yaqiniswa, indandatho yokubopha uphawu icindezelwe ethekwini lokucindezela lenzwa ukuvimba inzwa. Lapho ucindezelwe, i-Medical Medium ayinakungena, kepha lapho ingcindezi iphezulu, indandatho yokufaka uphawu ivulwe ngokuzumayo, futhi inzwa yokucindezela ingaphansi kwengcindezi. Okunhlobonhlobo. Indlela engcono kakhulu yokuxazulula lolu hlobo lokwehluleka ukususa inzwa bese ubheka ngqo ukuthi ngabe isikhundla se-zero sijwayelekile yini. Uma isikhundla se-zero sijwayelekile, buyisela indandatho yokubopha uphawu bese uzama futhi;

Okwesithathu ukuthi isiginali yokuphuma ye-transmitter ayizinzile. Lokhu kwehluleka kungenzeka kube yinkinga ecindezelayo. Umthombo wengcindezi ngokwawo uyingcindezi engazinzile, okungenzeka ukuthi ibangelwa ikhono elibuthakathaka lokulwa nokuphazamiseka kwensimbi noma inzwa yokucindezela, ukudlidliza okunamandla kwenzwa yezinzwa uqobo, kanye nokwehluleka kwenzwa; Okwesine ukuphambuka okukhulu phakathi kokudlulisela kanye ne-pointer Pressure Gauge. Ukuphambuka kuyinto ejwayelekile, vele uqinisekise ububanzi obujwayelekile bokuphambuka; Uhlobo lokugcina lokwehluleka okuthambekele ethonyeni yithonya lesikhundla sokufaka se-transmitter ehlukile ekukhishweni kwe-zero.

Ngenxa yohlu oluncane lokulinganisa lokudluliselwa kwengcindezi ehlukile, into ezwakalayo ku-transmitter izothinta umphumela wokudluliselwa kwengcindezelo ehlukile. Lapho ufaka, i-axis yengcindezelo yengcindezi yomhambisi kufanele ibe nge-perpendicular ekuqondisweni kwamandla adonsela phansi. Ngemuva kokufaka nokulungisa, lungisa isikhundla se-zero se-transmitter kuya kunani elijwayelekile.

4. Izindaba ezidinga ukunakwa nokulungiswa ngesikhathi sokusebenzisa izinzwa zokucindezela kanye nokudlulisela

1. Izindaba ezidinga ukunakwa ngesikhathi sokusebenzisa.

Isikhundla sokufaka esifanelekile se-transmitter ku-Pipeline yenqubo sihlobene ne-Medium ephakeme. Ukuze uthole imiphumela emihle yokulinganisa, amaphuzu ambalwa kufanele anake. Iphoyinti lokuqala ukuvimbela ukudlulisela ekuxhumaneni nemidiya ewonakalisayo noma eshisiwe; Iphuzu lesibili ukukala ingcindezi yoketshezi, ithempeli lokucindezela kufanele livulwe ohlangothini lwepayipi lenqubo ukugwema ukudideka kwe-slag; Iphuzu lesithathu ukuvikela i-slag ekukhishini kwangaphakathi kwe-conduit; Iphuzu lesine lingukuthi lapho ulinganisa ingcindezi yegesi, ithempeli lokucindezela kufanele livulwe phezulu kwepayipi lenqubo, futhi i-transmitter kufanele futhi ifakwe engxenyeni engenhla yepayipi lenqubo ukuze uketshezi oluqoqiwe lungafakwa kalula kwipayipi lenqubo; Iphuzu lesihlanu ukukala umusi noma eminye imithombo yezinga eliphakeme lokushisa, kuyadingeka ukwengeza i-condenser efana ne-buffer tube (ikhoyili), kanye nokushisa okusebenzayo kwe-transmitter akufanele kudlule umkhawulo; Iphuzu lesithupha ukuthi ishubhu eliqondisayo lengcindezi kufanele lifakwe endaweni lapho ukuguquguquka kokushisa kuncane khona; Iphoyinti lesikhombisa lapho kufiphala kwenzeka ebusika, umdluliseli ofakwe ngaphandle kumele athathe izinyathelo zokulwa nokushayisana ukuvikela uketshezi ethekwini lokucindezela kusuka ekukhuliseni nasekubangeleni inzwa; Iphoyinti lesishiyagalombili likhona lapho i-wiring, dlulisa ikhebula ngokuhlanganiswa kwamanzi noma ukugoqa ishubhu eliguqukayo futhi liqinise i-nut yokubopha ukuvimbela amanzi emvula ukuba avuke izindlu zokudlulisela intambo ngentambo; Iphuzu lesishiyagalolunye yilapho ulinganisa ingcindezi ye-liquid, isikhundla sokufaka se-transmitter kufanele sigweme umthelela woketshezi ukugwema ukulimala ngokweqile kwenzwa.

2. Ukulungiswa kwengcindezelo yokudlulisela.

I-Transmitter yengcindezi iyadingeka ukuthi ihlolwe kanye ngesonto kanye kanye ngenyanga. Inhloso enkulu ukususa uthuli kuthuluzi, hlola ngokucophelela izingxenye zikagesi, bese uhlola inani lamanje elivame njalo. Ingaphakathi le-Transmitter yengcindezi libuthakathaka, ngakho-ke kumele lihlukaniswe ngogesi oqinile wangaphandle.
