Zvishongedzo zveDifferential Pressure Transmitter

Mukushanda kwakajairika, zvishongedzo zvakawanda zvinowanzo shandiswa kubatsira ma transmitter e pressure akasiyana kuti ashande zvakanaka. Chimwe chezvinhu zvakakosha i valvu manifold. Chinangwa chekushandiswa kwayo ndechekudzivirira sensor kubva kudivi rimwe chete pamusoro pekumanikidzwa uye kuparadzanisa transmitter kubva mukuita panguva yekugadzirisa, kugadzirisa kana kutsiva. Manifold ye3-valve yakajairika inosanganisira vharuvhu imwe chete yekuenzana uye mavharuvhu maviri eblock anoenderana nedivi repamusoro nepasi rekumanikidzwa kwe transmitter. Mavharuvhu ese akabatanidzwa mu simbi block inobatanidza kamuri re transmitter kuburikidza ne process connection.

Mushure mekunge kuiswa kwapera, kuti utange kuyera, vhura vharuvhu yekuenzana kutanga, wobva wavhura mavharuvhu eblock ari padivi re low ne high pressure zvakatevedzana. Mirira kusvika kumanikidzwa kuri mumitsetse kwagadzikana, vhara vharuvhu yekuenzana zvakasimba wosiya mavharuvhu eblock akavhurika, wobva wagadzirira differential pressure kana flow detection. Kuti ubvise transmitter, vhara vharuvhu ye side pressure yekuenzana, vhura vharuvhu yekuenzana wovhara vharuvhu ye side pressure yekuenzana kuti uve nechokwadi chekuti residual pressure mu transmitter chave pasi sezvinobvira. Pakupedzisira, vhura bleed fittings kuti ubvise residual pressure mushure mekunge chishandiso chabviswa pakushanda.

Imwe mhando yeDP transmitter inowanzo shandiswa i5-valve manifold, iyo inobatanidza mavharuvhu maviri emorel bleed zvichibva pa3-valve. Mamwe mavharuvhu akavakirwa mukati anobvumira kuti kumanikidzwa kwakasara kupfuurwe kunzvimbo iri kure pane kuti kupfuurwe pedyo nekamuri.

Sezvambotaurwa pamusoro apa, kumanikidzwa kwepakati nepakati kunofanira kuburitswa usati wabvisa transmitter yeDP kubva pabasa. Mamwe marudzi e manifold anogona kupa mavharuvhu anobuda ropa pabasa racho asi nzira yakajairika ndeye bleed fittings dzakasungirirwa pa transmitter chamber case kuburikidza ne thread connection. Sunungura wobvisa ma plugs, uye kumanikidzwa kwepakati nepakati kwasara kunobuda kubva mu orifices.

Pakupedzisira, zvinoonekwa kuti maDP transmitters anowanzoiswa pamabhuraketi. Bhuraketi rekuisa mapaipi rakagadzirwa kuti rive nenzira yakagadzikana yekubatanidza maDP transmitters panzvimbo yekushanda. Rinonyanya kugadzirwa neU-bolt uye plate yakatwasuka kana kuti L-shape.

Semugadziri wezvishandiso ane ruzivo anopa mhinduro yakanakisa yekugadzira otomatiki yefekitori, WangYuan anokwanisa kuzadzisa chero zvinodiwa zvezvishandiso zveduZvigadzirwa zveWP3051 zvakatevedzanaKana muine kusava nechokwadi kana kuda zvimwe zvinhu zvataurwa pamusoro apa ndapota inzwa wakasununguka kutibata.
