Iye anochengetedza valve mudziyo wekuchengetedza anoshandiswa kudzivirira kudzvinyirira mumidziyo yekumanikidza kubva mukuwedzera kukosha kukosha. Basa revhavha yekudzivirira rinowanikwa nekuita kwechiito chinotevera: Kana iyo system inosvika pakumanikidzwa kukuru kunobvumirwa, valve yekuchengetedza inogona kuzarura zvakarurama, uye nokukurumidza inosvika pakureba kwekuvhura kwepamusoro, uye kusunungura huwandu hwehuwandu hwekushanda; chivharo chekuchengetedza chiri munzvimbo yakazaruka Kubuda kunofanira kugadzikana; apo dhigirii yehurongwa inodonha kune imwe kukosha, valve yekuchengetedza inofanira kuvharwa munguva, uye muhurumende yakavharwa, inofanira kuchengetwa mumhando yakavharwa. Izvi zvinotevera zvinotsanangura zvakakosha kuita zvinodiwa zvekuchengetedza mavharuvhu.
1. Vhura nemazvo
Ivhavhavha yekuchengetedza inofanirwa kuvhurika zvakavimbika kune yakatsanangurwa yekuvhura kureba pasi pekumanikidzwa kwakafanotemerwa uye kusvika kune yakatsanangurwa yekuburitsa simba. Ichi ndicho chinonyanya kudiwa chevhavha yekuchengetedza. Ndiko kuti, kana iyo inlet kudzvanywa kwevhavhavha yekudzivirira inosvika kune yakafanotemerwa kudzvanywa, vharanda rekuchengetedza rinofanira kuvhurika nemazvo uye nekukurumidza kusvika kune yakatarwa yekuvhura kureba.
Kana dzvinyiriro muhurongwa ichisvika pakumanikidzwa kwakanyanya kunobvumidzwa, mhinduro isinganzwisisike yevhavhavhavha yekudzivirira kusvika pakuwedzera kwekumanikidza kunotungamira kumamiriro ezvinhu ane njodzi akadai sekuputika uye kukuvara kwemaboilers, midziyo yekumanikidza uye mapaipi. Kunyanya kune compressible gasi media, njodzi iri pamusoro.
Iyo yakagadzika kudzvanywa kwevhavha yekudzivirira haifanirwe kuve yakakura kudarika dhizaini yekumanikidza kukosha kweiyo bhailer, kumanikidza mudziyo uye pombi.
Kutsauka kwekumanikidzwa kwakanaka kwevhavhavhavhavha yekuchengeteka kunotsanangurwa zvakajeka mumitemo yakakodzera uye zviyero. Kana vhavha yekudzivirira ichigadziriswa nokuda kwekumanikidza kwekugadzirisa, kutsauka kwayo kunofanira kunyatsodzorwa mukati mehutano hwakatarwa.
2. Kuburitsa kwakagadzikana
Mushure mekunge vharuvhu yekudzivirira yasvika pakakwirira yakavhurwa yekuvhura, inochengetedza yakagadzikana yekuburitsa mamiriro uye inogona kuburitsa yakayerwa huwandu hwekushanda kwepakati. Panofanira kunge paine yakanaka michina zvivakwa (hapana frequency kusvetuka, chatter, nezvimwewo) panguva yepakati discharge process. Ichi chinodiwa chakakosha zvikuru.
Ivhavha yekudzivirira inofanira kuva nechimiro chakanaka uye chitubu chine kuoma kunonzwisisika kuchengetedza maitiro akanaka emagetsi uye kugadzikana kwekubuda simba. Ukuru hwekuyerera kwevhavhavhavhavha yekudzivirira inofanira kusangana nezvinodiwa parameter zvinodiwa pakuverenga. Kana iyo mhiri-chikamu nharaunda yekuyerera idiki zvakanyanya, mushure mekuvhurwa kwevhavhavhavha, iyo yakawandisa chikamu chepakati haigone kuburitswa nenguva, uye system yekumanikidza inoramba ichikwira, izvo zvine njodzi. Pane zvinopesana, kana nzvimbo yemuchinjikwa-chikamu chekuyerera ichinyanya kukura, mushure mokunge vheji yekudzivirira yakavhurwa, kudzvinyirira kunodonha zvakanyanya pasi pekushanda kwekushanda, uye dhivhavha yevhavhavhavha yevhavha inovhara uye inokonzera mhirizhonga pachigaro chevhavha; zvisinei, nokuti iyo system pressure rise factor haisati yabviswa, disc ichavhura zvakare kuti iite kusvetuka kwefrequency, uye semugumisiro, chigaro chevhavha uye chisimbiso chepamusoro che diski chichakuvadzwa nekuda kwezvakadzokororwa. Kana mavharuvhu ekuchengetedza achishandiswa zvinwiwa zvisingagoneki, kusvetuka kwefrequency kunogona kukonzera sando yemvura muhurongwa.
Iyo inlet pressure yevhavhavha yekudzivirira kana yasvika payero yekuvhura kureba inonzi discharge pressure. Inoshandiswa mumidhiya yakasiyana kana midhiya yakafanana pasi pemamiriro akasiyana ekushanda, uye yakatemerwa kuburitswa kwayo kwakasiyana, iyo inotsanangurwa zvakajeka mumirau yakakodzera uye zviyero. Inowanzotaridzwa seye muzana yekumanikidzwa kweseti inodarika kukosha. Chimiro chegadziriro yevhavhavha yekudzivirira inofanira kuva nechokwadi chokuti iyo yakatemerwa dhizaini yekumanikidza inodzorwa zvakanyanya mukati meiyo yakatarwa.
3. Kuvhara nenguva
Kana kubuda kwevhavhavhavha yekudzivirira kunoderedza kudzvinyirira kwepakati kune imwe kukosha, kuputika kwevhavha inowira mukusangana nepamusoro pekuvhara kwechigaro chevhavha uye inosvika kune yakavharwa zvakare. Ivhavha yekudzivirira inogona kugara uye yakavharwa munguva uye inobudirira, iyo inokosha chiratidzo chekushanda kwakanaka.
Chiito chevhavhavha yekudzivirira hazvidi kuti midziyo kana system irege kushanda kana kugadziriswa. Dzimwe nguva, chiito chevhavha yekudzivirira chinokonzerwa nezviitiko zvetsaona zvakadai se misoperation muhurongwa. Muchiitiko ichi, hazvidiwi kuti kudzoka kunodzvinyirira kwevhavhavhavhavha yakanyanyisa kudarika kushanda kwekushanda. Kunyanya kuderera kwekudzoka kunoreva kurasikirwa kwakanyanya kwesimba nepakati, uye kunovhiringidza kushanda kwakajairika kwehurongwa hwose. Pane zvinopesana, chigaro chemashure chekumanikidzwa hachisi chakanyanya kukwirira. Kana mhepo yekudzoka iri pedyo nekuvhuvhuta kwekuvhura, zviri nyore kuita kuti valve yekuchengetedza ivhurwe zvakare, zvichiita kuti valve yekuchengetedza isvetuke nguva dzose, uye haibatsiri kugadzirisa zvakare chisimbiso mushure mekuvhara. Mukuwedzera, munyaya iyo valve yekuchengetedza haigoni kuvharwa zvakavimbika, sezvo iyo yepakati pakati pekuvhara zvisimbiso haina kugurwa zvachose, hazvibviri kudzorera kushanda kwechisimbiso pasi pesimba rekushanda kwemaitiro.
Kugadzirwa kwevhavha yekudzivirira kunofanira kuva nechokwadi chokuti inogona kuvharwa nokukurumidza uye inobudirira. Kukurumidza uye kwakasimba kudzoka kwechigaro kunobatsira pakugadzwa kwechisimbiso pane kudzoka zvishoma nezvishoma uye zvishoma nezvishoma chigaro.
Chigaro chekudzoka kwekuita kwevhavhavha yekudzivirira inoyerwa nekuvhura kudzvanywa kukosha, iyo inowanzogadziriswa nekuvhura uye kuvhara kwekumanikidza musiyano. Mavharuvhu ekuchengetedza anoshandiswa kune akasiyana midhiya ane akasiyana kuvhura uye kuvhara kudzvanywa misiyano, iyo inotsanangurwa zvakajeka mumirau yakakodzera uye zviyero.
4. Chisimbiso chakavimbika
Kana iyo yakachengetedzwa sisitimu iri pane yakajairika yekushanda kumanikidza, iyo yakavharwa yekuchengetedza vharafu ine yakanaka uye yakavimbika yekuisa chisimbiso kuita. Nemhaka yokuti valve yekuchengetedza inodonha, iyo inoshandiswa inoshandiswa (dzimwe nguva inodhura zvikuru kana ine ngozi) icharasika, kushandiswa kwesimba kuchawedzerwa, uye nharaunda yakapoteredza uye mhepo ichasvibiswa nepakati yekushanda. Kudonha kwakanyanya kunozokanganisa kushanda kwakajairwa kwemidziyo kana sisitimu, uye kutomanikidza mudziyo kuti umire kushanda. Kudonha kunoramba kuchiita kunokanganisa zvakare chisimbiso chevhavhavhavhavha, zvichikonzera kutadza kuzere kwevhavhavhavha yekudzivirira.
Kuisazve chisimbiso mushure mekuvhara kwevhavha yakashandiswa zvakanyanya kuoma kupfuura kuchengetedza chisimbiso chepakutanga. Nekuti vharuvhu yekuchengetedza yakavharwa, iyo yepakati dzvinyiriro inobata panzvimbo hombe yevhavha disc, asi isati yavhurwa, inongoshanda pane diki diki nzvimbo yakavharirwa nechisimbiso chepamusoro. Nokudaro, kushandiswa kwechisimbiso kwevhavha yekudzivirira kunogona kuderedzwa mushure mekushanda, uye nokudaro inorasika. Kunyanya, zvakanyanya kuoma kugadzirisa chisimbiso chemashure-chega chega chakananga chichiita chekuchengetedza valve. Mumavhavhavha ekuchengetedza ane nzira dzekubatsira dzekushanda, dambudziko iri rinogadziriswa nenzira yekumanikidzirwa chisimbiso.
Zvakanyanya kuoma kuda mavharuvhu ekuchengetedza kuchengetedza kusimba kupfuura mavharuvhu anowanzo shandiswa pakuvhara mavharuvhu. Nemhaka yokuti hapana simba guru rinoshandiswa pakati pezvisimbiso, dhisiki yevhavha yekudzivirira inonamatira kune chigaro chevhavha chete kuti iite chisimbiso chisimbiso nechisimbiso chiduku chakananga. Kusungirirwa kwechisimbiso kunotarirwa nemusiyano pakati pekugadzirisa kwekuvhara kwevhavha yekudzivirira uye kushandiswa kwekushanda kwechigadzirwa, kazhinji kacho kukosha kuduku (kazhinji 10% yekumanikidzwa kwekugadzirisa), saka ukuru uye hutsinye hwepamusoro hwechisimbiso chekuvhara kwevhavha yevhavha inodiwa.
Zvinodiwa zvekusimba kwevhavha yekudzivirira zvinosiyana zvichienderana nepakati kana mamiriro ekushanda. Kazhinji kutaura, zvakaoma kuwana vharafu yekuchengetedza ine simbi-metal sealing surface kuti iwane kusabuda. Ivhavhavha yekudzivirira ine yakapfava yekuisa chisimbiso chimiro chesimbi-nonmetal ine zvirinani kuita chisimbiso.
