Mukuyera maitiro emaindasitiri,zvinotakura zvinodzvinyirira zvakasiyanavane basa rekuona ma parameter akakosha akadai sekusiyana kwekumanikidzwa, mwero wemvura uye kuyerera. DP transmitter inoyera musiyano wekumanikidzwa pakati pemapoinzi maviri uye chinhu chayo chekunzwa (diaphragm capsule) chinonetsa. Kuisa kana kushanda zvisina kunaka—semuenzaniso, kuisa kumanikidzwa kwakanyanya kudivi rimwe chete—kunogona kukuvadza kana kutoparadza zvachose transmitter. Sechishandiso chakarurama chinoshandiswa pakuyera nekudzora kugadzirwa, kushanda kwayo kwakachengeteka uye kwakarurama kunoenderana zvakanyanya nevharuvhu ine chekuita nayo.
Muchina wekudhindisa we differential pressure unoda vharuvhu yakawanda nekuda kwezvikonzero zvinotevera:
Chinodiwa chekudzivirira:Chinotumira cheDP chinoyera musiyano wekumanikidzwa pakati pemakamuri aro ekumanikidzwa kwepamusoro neakaderera. Kana mavharuvhu ari kumativi maviri akasashanda zvakanaka panguva yekuiswa, kuvharwa kana kugadziriswa, chinotumira chinogona kuiswa pasi pekumanikidzwa kwakazara kwesimba kudivi rimwe chete, zvichigona kukuvadza diaphragm yakapfava. Vharuvhu yekuenzana iri mumanifold inopa nzira yekuenzanisa kumanikidzwa kumativi ese maviri isati yashandiswa sedhizaini yakakosha inodzivirira kukuvara kwemuchina.
Chinodiwa chekugadzirisa:Chishandiso chega chega chekuyera hachina kudonha zvachose. Chinotumira DP chinoda kuti chiratidzo chayo chekubuda chiongororwe uye chigadziriswe kune iyo theoretical zero point kana differential pressure iri zero. Nekuvhara mavharuvhu eH neL block uye kuvhura equalizing valve, mamiriro echokwadi e zero-differential-pressure anogona kugadzirwa pasina kukanganisa maitiro, zvichibvumira online zero calibration kuti ive nechokwadi chekuti kuyera kwenguva refu kwakarurama.
Chinodiwa pakugadzirisa:Mitsetse yema "impulse" inogona kuungana negasi, kunyungudika kana tsvina, zvichikonzera kukanganisa kana kuvharika kwechiratidzo. Saka mavharuvhu akatsaurirwa anodiwa pakuburitsa mweya, kubvisa mvura (kuputika) uye kusukira.
Mavharuvhu matatu ndiwo anonyanya kushandiswa pakutumira mavharuvhu eDP. Ane mavharuvhu maviri ekuparadzanisa mavharuvhu (block) uye vharuvhu rimwe chete riri pakati. Munguva yekushanda kwakajairika, mavharuvhu maviri eblock anovhurwa uye vharuvhu yekufananidza inovharwa, zvichibvumira nzira yekushandura kupinda mumakamuri ekumanikidza akanaka neasina kunaka etransmitter zvichiteerana uye kuyera kumanikidzwa kwedhiriji panguva chaiyo. Zvisinei, panguva yekushanda kana kudzima, nzira yekushanda "tanga wavhura vharuvhu yekufananidza, wobva washandisa (vhura kana kuvhara) mavharuvhu eblock" inofanira kutevedzerwa zvakanyanya. Chinangwa ndechekudzivirira kumanikidzwa kwetransmitter kune rumwe rutivi. Kana kumanikidzwa kwakanyanya kukangoerekana kwaiswa kune rumwe rutivi, kumanikidzwa kukuru kweunidirectional static kunogona kukuvadza pakarepo fragile sensor diaphragm - chikonzero chinowanzoitika chekukundikana kwemidziyo. Vharuvhu yekufananidza inochengetedza kumanikidzwa mumakamuri eH & L kwakaringana mukati mekuita kwekuzadza kana kuderedza kumanikidzwa, nokudaro ichidzivirira sensor.
Manifold ye5-valve inovakwa kubva pakugadzirwa kwemavharuvhu matatu nekuwedzera mamwe mavharuvhu pamativi ese ekumanikidzwa kweH & L. Manifold ye5-valve yakajairika ine mavharuvhu maviri eblock, vharuvhu imwe yekuenzana uye mavharuvhu maviri ekuburitsa mvura kana kuburitsa mweya. Chaizvoizvo, manifold ye5-valve inofukidza mabasa ese emavharuvhu matatu uye inoita danho rakanaka mukushanda nekugadzikana uye nyore kugadzirisa.
Mukushandiswa kwazvinoita, pakuyera mvura yakachena kana magasi asina tsvina, asingawanzo kuomeserana kana kuda kupfurwa kakawanda, 3-valve manifold inogona kuzadzisa zvinodiwa zvizere. Mienzaniso inosanganisira kuyerwa kwekuyerera kwemapaipi emhepo yakamanikidzwa kana kuyerwa kwemazinga muhurongwa hwemvura hwakacheneswa, uko medium yakachena uye yakagadzikana, mitsetse yekufema haigone kuvharika uye kudiwa kushoma kwekugadzirisa. Muzviitiko zvakadaro, 3-valve manifold isarudzo inodhura uye yakavimbika. Chero bedzi vashandisi vachinyatsotevedzera maitiro evharuvhu yekuenzana, manifold inogona kushanda isina matambudziko kwenguva yakareba.
Zvisinei, panzvimbo dzemaindasitiri, nzira iyi inogona kunge isiri yakanaka zvachose. Pakuyera utsi, gasi rine guruva kana tsvina, kuunganidzwa kwe condensate kana kuvharika kwezvikamu mumitsetse ye impulse zvinogona kukonzera kunonoka kwekuyera, zvikanganiso kana kutokundikana. Mumamiriro ezvinhu aya, mavharuvhu maviri e drain e 5-valve manifold anobvumira kubvisa drain uye condensate online pasina kuparadzanisa mitsetse ye impulse kana kudzima loop yese yekuyera. Nyanzvi dzemidziyo yemumunda dzinongoda kuvhara mavharuvhu e block uye kuvhura mavharuvhu e drain; vanogona kuunganidza marara mumudziyo kana kuchenesa ne steam kuti vachenese nekukurumidza. Iyi inzira huru mu petrochemical uye power installations dzinoda kuenderera mberi kwekugadzirwa, zvichivandudza mashandiro ekugadzirisa uku zvichideredza njodzi ye medium spray kana leak.
Kana kusarudza manifold ane mavharuvhu matatu kana mashanu emudziyo wekumanikidza musiyano kunofanirwa kusarudzwa zvichienderana nezvinodiwa zvakafanana zvepurojekiti, pamwe chete nemamiriro epakati, marongerwo ekuisa, uye hurongwa hwekushanda nekugadzirisa.Shanghai Wangyuaninyanzvi yekugadzira michina, ine ruzivo rwemakore anopfuura makumi maviri muindasitiri. Kana uine zvaunoda kana mibvunzo maererano nesarudzo yezvinotakura zvinodzvinyirira zvakasiyanauye mavharuvhu manifolds, ndapota inzwa wakasununguka kubata Shanghai Wangyuan kuti uwane mhinduro yakakodzera yekuyera.
