Kwimisebenzi eqhelekileyo, izixhobo ezininzi zisetyenziswa rhoqo ukunceda ii-differential pressure transmitters ukuba zisebenze ngokufanelekileyo. Esinye sezixhobo ezibalulekileyo yi-valve manifold. Injongo yokusetyenziswa kwayo kukukhusela i-sensor kumonakalo wecala elinye phezu koxinzelelo kunye nokwahlula i-transmitter kwinkqubo ngelixa ilungiswa, ilinganiswa okanye itshintshwa. I-3-valve manifold eqhelekileyo ibandakanya i-equalizing valve enye kunye nee-block valves ezimbini ezihambelana necala eliphezulu neliphantsi loxinzelelo lwe-transmitter. Zonke ii-valve zidityaniswe kwi-metal block edibanisa igumbi le-transmitter ngokudibanisa inkqubo.
Emva kokuba ufakelo lugqityiwe, ukuze uqale ukulinganisa, vula ivalvu yokulinganisa kuqala, uze uvule iivalvu zebhloko kwicala eliphantsi neliphezulu ngokulandelelana. Linda ude uxinzelelo olukwimigca luzinze, vala ivalvu yokulinganisa kakuhle uze ushiye iivalvu zebhloko zivulekile, emva koko isixhobo sikulungele ukufunyaniswa koxinzelelo olwahlukileyo okanye ukuhamba kwamanzi. Ukuze uhlukanise itransmitter, vala ivalvu yebhloko yecala eliphantsi, vula ivalvu yokulinganisa uze uvale ivalvu yebhloko yecala eliphantsi ngasemva ukuqinisekisa ukuba uxinzelelo olushiyekileyo kwigumbi lokudlulisa lugcinwa luphantsi kangangoko kunokwenzeka. Ekugqibeleni, vula izixhobo eziphuma igazi ukuze ucime uxinzelelo olushiyekileyo emva kokuba isixhobo sinqunyulwe kwinkqubo.
Olunye uhlobo oluqhelekileyo lwe-DP transmitter yi-5-valve manifold, edibanisa iivalvu ezimbini ze-morel bleed ngokusekelwe kwi-3-valve. Iivalvu ezongezelelweyo ze-bleed ezakhelwe ngaphakathi zivumela uxinzelelo olusele ukuba luphume luye kwindawo ekude endaweni yokuba lukufutshane negumbi.
Njengoko kukhankanyiwe apha ngasentla, uxinzelelo oluphakathi oluqokelelweyo kufuneka lukhutshwe ngaphambi kokuba kususwe i-DP transmitter kwinkonzo. Ezinye iintlobo ze-manifold zinokubonelela ngeevalvu eziphuma igazi kulo msebenzi kodwa indlela eqhelekileyo kukufakelwa kwegazi okufakwe kwi-transmitter chamber case ngoqhagamshelo lwentambo. Khulula kwaye ususe iiplagi, kwaye uxinzelelo oluphakathi oluseleyo luya kukhutshwa kwii-orifices.
Ekugqibeleni, kuyaphawuleka ukuba ii-DP transmitters zihlala zifakelwa kwiibrakethi. I-pipe mounting bracket yenzelwe ukubonelela ngendlela ezinzileyo yokuncamathisela ii-DP transmitters kwindawo yokusebenza. Iquka ikakhulu i-U-bolt kunye nepleyiti ethe tye okanye enomfanekiso we-L.
Njengomvelisi wezixhobo onamava obonelela ngesisombululo esingcono sokwenza izinto ngokuzenzekelayo kumzi-mveliso, uWangYuan unako ukwanelisa naziphi na iimfuno zethu zezixhoboIimveliso zothotho lweWP3051Ukuba unamathandabuzo okanye ufuna ezinye izixhobo ezingasentla nceda unxibelelane nathi.
