Nzira yekugadzirisa sei kukanganisa kwemagetsi valve positioner? Kubatsira uye kuipa kwevhavha yemagetsi uye pneumatic valve

Nzira yekugadzirisa sei kukanganisa kwemagetsi valve positioner? Zvakanakira uye zvakaipira zvemagetsi vharafu uye pneumatic vharafu Magetsi vharafu chinzvimbo, inozivikanwawo sepneumatic valve positioner, ndiyo huru yemidziyo yemutongi, inowanzo shandiswa nepneumatic regulator, inogamuchira chiratidzo chinobuda cheiyo regulator, uyezve neinobuda chiratidzo. kudzora pneumatic regulator, kana regulator chiito, kutamiswa kwevhavha hunde uye kuburikidza nemakanika mudziyo mhinduro kune vharafu chinzvimbo, nzvimbo yevharuvhu kuburikidza nechiratidzo chemagetsi kune iyo yepamusoro system. Kuburikidza neanopfuura makore makumi maviri eruzivo rwekuunganidza, uye tekinoroji mainjiniya uye yemagetsi valve positioner rational analysis yakasanganiswa nenhamba huru yeruzivo rwekugadzirisa munda, electric valve positioner fault classification, kuongororwa kwechikonzero chekukanganisa uye kutsvaga nzira yekugadzirisa dambudziko, I. tarisiro yekupa vashandi vezviridzwa mukugadzika uye kugadzirisa kweiyo actuator kana kugadzirisa kwezuva nezuva kwemagetsi valve positioner kubatsira. 1. Air source pressure fluctuation yemagetsi valve positioner Tarisa air filter pressure reducer, pasi pemvura netsvina. 2, iyo yemagetsi valve positioner ine chiratidzo chekuisa asi iyo inobuda idiki kana kwete Nekuda kwekunyanyisa kugadzirisa kwerwendo trimmer screw yenzvimbo, iyo coil ye torque mota haina welded, uye inotungamira inogona kusungirirwa. Torque mota coil yemukati waya inopwanya kana kupisa kunze nekuda kwekupfuura; Shandisa multimeter kuyera kuramba kwecoil. Kazhinji, inofanira kuva inenge 250. Kana kutsauka kubva ku 250 L kwakakurisa, shandura coil. Signal cable contact haina kunaka; Tarisa ma wiring terminals kuti ubvise kusunungura. Signal tambo yekubatanidza yakadzoserwa kumashure: Tarisa kana iyo (+) (-) terminal yekubatanidza yadzoserwa kumashure. Nozzle baffle chinzvimbo haina kururama: gadzirisa parallelism, ona kubuda kwekuchinja. Loose nozzle fixing screw: simbisa siruu inogadzirisa mhino kuti isangane nezvinodiwa pakufamba. Iyo amplifier yakanganisa; Tarisa uone kana amplifier yakanganisa kana kuitsiva. Pneumatic blockage: Shandisa 0.12 kupfuudza tsvina. Vent blockage: chigaro chepasi cheiyo locator, pane mhepo inoputika, kana iwe ukasateerera kune blockage, iyo locator inomira kushanda. Baffle lever connection spring deformation kana kuputsika; Vhura chivharo chelocator wochitsiva. Shandura danda remagineti anogara uye tarisa kana valve inoshanda. Feedback lever inodonha; Rongedza parallelism uye ona kuti vharafu inoshanda sei. Feedback lever range yakagadziriswa pini skew: Gadzirisa pini kuti isangane nezvinodiwa zvekufamba. Ivhavha inogadzirisa ine vhiri remaoko hairove kusvika panzvimbo yepakati; Tarisa handwheel chinzvimbo chekuchengetedza vharafu uye uigadzirise kunzvimbo yepakati. Yakasununguka CAM kana nzvimbo isina kunaka; Simbisa iyo CAM kana gadzirisa chinzvimbo cheCAM. Hydraulic control valve flapper lever spring stiffness haina kukwana: shandura (+) (-) polarity wiring, gadzirisa kureba pakati peflapper uye nozzle, kusangana nezvinodiwa zvekufamba (zvino unoda kushandura maitiro emutongi). 3, electric valve positioner inobuda pressure oscillation Tsvina mune amplifier: Tsvina mune amplifier. Kubuda pombi kana firimu musoro kuvuza: bvisa kuvuza chiitiko, ita kuti vharuvhu ishande zvakanaka. Firimu musoro diaphragm kuchembera: kutsiva kuchembera diaphragm inogona kuva. Chisingaperi magineti diverging kukanganisa: gadzirisa parallelism yekusingaperi magineti kubvisa kusagadzikana kwemagineti. Loose screw inogadzirisa mhinduro lever: firita inosimbisa gadziriso sikuru yekubvisa kuzunguzika kwevharuvhu. Yakakura AC chikamu chechiratidzo chekuisa: bvisa AC chikamu kana kufanana ne capacitor pamagumo ekuisa. Sefa kukanganisa kwe AC. Back pressure air road ine tsvina: bvisa tsvina, troubleshooting. Valve tsvimbo radial kusunungura: tarisa vharafu inogadzirisa. 4, yemagetsi valve positioner haina chekupinza uye inobuda Backpressure block: Vhara tsvina. Kana nzvimbo ye otomatiki uye manual switch isiri iyo, iyo otomatiki uye manual switch ichatenderedzwa newachi kuenda kunzvimbo yeatomatiki cheki valve. 5. Kururama kwemagetsi evhavha positioner haisi yakanaka Nozzle, kumira kweplate kugadziridzwa hakuna kunaka: gadzirisa parallelism kana nozzle fixing screw, kusangana nezvinodiwa zvakarurama. Gedhi vharafu kumashure kumanikidzwa kwemhepo kubuda; Bvisa kubuda kwemhepo. Iyo radial displacement yevhavha inogadzirisa yakakura: tarisa vharafu inogadzirisa. Kugadziriswa kusina kunaka kwe zeroed screw: Gadzirisa zeroed screw kuti isangane nekurongeka kwezvinodiwa. Feedback lever uye yakagadziriswa pini chinzvimbo kukanganisa kukanganisa: Retedza nzvimbo yepini zvinoenderana nezvinodiwa zvekufamba. Zvakanakira uye zvakaipira zvepneumatic valve chiito chinhambwe chakakura kupfuura vharafu yemagetsi, iyo pneumatic valve switch yekumhanyisa inogona kugadziridzwa, yakapusa chimiro, nyore kuchengetedza, mukuita chiito nekuda kwebuffer maitiro egasi pachayo, kwete. nyore kukuvadzwa nejamming, asi inofanira kuva nemhepo inobva, uye maitiro ayo ekutonga akanyanya kuoma kupfuura valve yemagetsi. Pneumatic valve mhinduro inokurumidza, yakachengeteka uye yakavimbika, mafekitori mazhinji ane yakakwirira kudzora zvinodiwa akagadzirirwa pneumatic chiridzwa kudzora zvinhu kumisikidzwa compressed air station. Magetsi zvinoreva magetsi.
