Litšobotsi tsa mitha ea phallo ea vortex

E ka lekanya mefuta e meraro ea mecha ea phatlalatso ho kenyeletsoa le metsi, likhase, le mouoane o tletseng/o chesang haholo lefatšeng ka bophara. E loketse metsi a pholileng a indasteri, li-solvent tsa lik'hemik'hale, khase ea tlhaho, moea o hatelletsoeng le mouoane oa indasteri, e felisa tlhoko ea limithara tse arohaneng bakeng sa maro a fapaneng le ho fokotsa litšenyehelo tsa theko le tsamaiso tsa bareki.

Ha ho na likarolo tse tsamaeang ka hare ho mithara. Likarolo tsa mantlha ke 'mele e sa sisinyeheng ea bluff le li-sensor, tse qobang mathata a kang ho tsofala ha impeller, ho silafatsa le ho koaleha ha li-flow metres tsa setso. Ha e hloke ho qhaqhoa le ho hloekisoa khafetsa tlas'a maemo a tloaelehileng a ts'ebetso, e hloka feela tlhahlobo ea nako le nako ea terata ea sensor. Bophelo ba ts'ebeletso bo ka feta lilemo tse 10, e leng se fokotsang haholo litšenyehelo tsa tlhokomelo ea nako e telele.

Ho latela molao-motheo oa Karman Vortex Street, ho nepahala ha tekanyo (±1.0%FS – ±1.5%FS) ho itšetlehile haholo ka maqhubu a vortex 'me ha ho angoe ke ho feto-fetoha ha bongata ba mokelikeli, khatello, kapa mocheso ka har'a sebaka se itseng. Moralo o koetsoeng oa ntlo ea mithara le sensor o hanela tšitiso ea motlakase, lerōle le mongobo libakeng tsa indasteri, ho netefatsa hore tekanyo e phetoa hantle.

Karolelano ea ho theoha ha motlakase e fihla ho 1:10 ho isa ho 1:20, e leng se loketseng maemo a nang le liphetoho tse kholo tsa phallo (joalo ka ho fepa lik'hemik'hale le ho lokisa mojaro oa boiler ea mouoane). Li-caliber tse tloaelehileng li koahela DN15 - DN300, 'me mehlala e meholo e ikhethileng (ho fihlela ho DN600) e fumaneha ho fihlela litlhoko tsa tekanyo ea liphaephe tse nyane le liphaephe tse kholo tsa indasteri.

'Mele o boreleli o sebelisa moralo o bonolo, o fellang ka khanyetso e tlase ea mokelikeli ha o feta. Tahlehelo ea khatello ea eona e tlase haholo ho feta ea li-flow metres tsa orifice le li-flow metres tsa turbine. Tšobotsi ena e fokotsa tšebeliso ea matla ea sistimi ea lipalangoang tsa liphaephe, haholo-holo liphaepheng tse kholo tsa indasteri, 'me e fokotsa haholo moroalo oa ts'ebetso ea lisebelisoa tsa motlakase tse kang lipompo tsa metsi le lifene, e fihlela litlhoko tsa ho boloka matla le tšireletso ea tikoloho.

E tšehetsa mekhoa e mengata ea ho kenya ho kenyeletsoa le likhokahano tsa flange le clamp-on. E na le litlhoko tse hlephileng bakeng sa likarolo tsa liphaephe tse otlolohileng tse holimo le tse tlase (hangata 10D holimo le 5D tlase), li loketse libaka tsa indasteri tse nang le sebaka se fokolang. Thepa ea mithara e ka fetoloa ka mokhoa o feto-fetohang: 'mele o fumaneha ka tšepe ea carbon, tšepe e sa hloekang ea 316L, Hastelloy, jj., 'me 'mele oa bluff o ka etsoa ka motsoako oa titanium kapa ceramic, o ka mamellang mocheso o phahameng, khatello e phahameng le mecha ea phatlalatso e senyang, e ikamahanya le mocheso oa -40℃ - 400℃ le khatello ea mosebetsi ea PN1.6 - PN4.0MPa.

Methapo ea phallo ea vortex ea sejoale-joale e kopantsoe haholo le li-converter tse bohlale, tse tšehetsang lets'oao la analog la 4 - 20mA le tlhahiso ea lets'oao la pulse. Li lumellana le liprothokholi tsa puisano tsa indasteri tse kholo tse kang MODBUS, HART, le Profibus, 'me li ka hokahana ntle le mathata le litsamaiso tsa taolo ea PLC le DCS, li phethahatsa tlhokomelo ea nako ea sebele, phetiso ea hole, le tsamaiso e bohareng ea data ea phallo ho fihlela litlhoko tsa tlhahiso ea indasteri e iketsang.
