Khangela ivalve CV12-20 yenkqubo enkulu yokuqukuqela kwamanzi

Umahluko phakathi kweenzwa zoxinzelelo, iirelays kunye nokutshintsha

1. Sonke sihlala siva malunga nenzwa yoxinzelelo, i-pressure relay kunye nokutshintsha uxinzelelo. Ngaba zidibene? Yintoni umahluko? Oku kulandelayo yintshayelelo eneenkcukacha yezi zintathu. I-sensor ye-pressure sensor iqulunqwe yinto echaphazelekayo yoxinzelelo kunye nesekethe yokuguqula, eyenza ukutshintshwa kancinci okwangoku okanye i-voltage output kwi-pressure-sensitive element ngokusebenzisa uxinzelelo oluphakathi olulinganisiweyo. Iinzwa zihlala zifuna ukusetyenziswa ngokubambisana neesekethe ze-amplifier zangaphandle ukugqiba inkqubo ukusuka ekuboneni uxinzelelo ukulawula kunye nokubonisa. Ngenxa yokuba i-sensor yoxinzelelo yinto ephambili, isignali eyondliwe yinzwa yoxinzelelo kufuneka iqhutywe, ihlalutywe, igcinwe kwaye ilawulwe ngumlinganiselo kunye nenkqubo yokulawula, eyenza izixhobo zokuzenzekelayo zoshishino kunye nokulawula ukusebenza kobunjineli bukrelekrele.

2. I-relay yoxinzelelo yinto yokuguqula umqondiso we-electro-hydraulic switch esebenzisa uxinzelelo lwamanzi ukuvula nokuvala uqhagamshelwano lombane. Isetyenziselwa ukuthumela imiqondiso yombane ukulawula izenzo zamacandelo ombane xa uxinzelelo lwenkqubo lufikelela kuxinzelelo olubekiweyo lwe-relay, ukuze kuqatshelwe ukulayishwa okanye ukukhulula ulawulo lwempompo, izenzo ezilandelelanayo ze-actuator, ukhuseleko lokhuseleko. kunye ne-interlock yenkqubo, njl njl. Iqukethe iinxalenye ezimbini: inxalenye yokuguqulwa koxinzelelo kunye ne-microswitch. Ngokweentlobo zesakhiwo samacandelo okuguqulwa koxinzelelo, kukho iindidi ezine: uhlobo lwe-plunger, uhlobo lwentwasahlobo, uhlobo lwe-diaphragm kunye nohlobo lwe-bellows. Phakathi kwazo, isakhiwo se-plunger sahlulwe saba luhlobo olulodwa lwe-plunger kunye nodidi lwe-double plunger. Uhlobo lweplunger enye lunokwahlulwa lube ziindidi ezintathu: iplunger, differential plunger kunye neplunger-lever. Ngokutsho koqhagamshelwano, kukho uqhagamshelwano olulodwa kunye nokutshatyalaliswa kombane kabini.

3. Uxinzelelo loxinzelelo lutshintsho olusebenzayo oluvula okanye lucime ngokuzenzekelayo xa lufikelela kwixabiso elibekiweyo ngokoxinzelelo olumiselweyo.

4. Ukutshintsha koxinzelelo kunye nokuhanjiswa koxinzelelo kunokuvulwa okanye ukucima kuphela phantsi koxinzelelo lwakho, olusetyenziselwa ukulawula indawo elula. Zonke ziziphumo zokutshintsha! I-Pressure relay inokubonelela ngee-nodes ezininzi zemveliso okanye iintlobo ze-node kunokutshintsha koxinzelelo. Imveliso yenzwa yoxinzelelo inokuba ngumqondiso we-analog okanye isignali yedijithali, ekulungele ukusetyenzwa emva kokulungiswa, kwaye ingatshintshwa ibe ngumqondiso we-standard transmitter yokuhanjiswa okude.
