Mavharuvhu anoshandiswa nepneumaticzvinhu zvakakosha mumabasa akasiyana-siyana emaindasitiri, zvichidzora kufamba kwemvura nemagasi zvinobudirira. Mavharuvhu aya anoshandisamaactuator emhepokuvhura nekuvhara otomatiki mashandiro acho, zvichibvumira kudzora kuyerera nekumanikidzwa kwacho. Muchinyorwa chino, tichaongorora mhando dzakasiyana dzemavharuvhu anoshandiswa nemhepo, kusanganisira mavharuvhu ebhora anoshandiswa nemhepo, mavharuvhu emapuruguru, mavharuvhu egedhi, mavharuvhu eglobe, uye mavharuvhu eSDV, tichitarisa pane zvakasiyana uye mashandisirwo awo.
Chii chinonzi vharuvhu inofambiswa nemhepo
Vharuvhu yekufema imuchina unoshandisa mweya wakamanikidzwa kuti ushande muchina wevharuvhu. Muchina uyu unoshandura simba riri mumhepo yakamanikidzwa kuita kufamba kwemuchina, uchivhura kana kuvhara vharuvhu. Rudzi urwu rwekushandisa otomatiki rwakakosha mumaindasitiri uko kushanda nemaoko kusingashande kana kuti kusina kuchengetedzeka, zvakaita sekugadzira makemikari, mafuta negasi, kurapwa kwemvura, uye kugadzira.
Zvakanakira zvikuru zvemavharuvhu anoshandiswa nemhepo ndiko kumhanya kwawo uye kuvimbika kwawo. Anogona kushandiswa nekukurumidza, zvichiita kuti ave akakodzera kushandiswa kunoda nguva yekupindura nekukurumidza. Pamusoro pezvo, masisitimu emhepo anowanzo kuve nyore uye asingadhuri kupfuura masisitimu emagetsi kana ehydraulic, zvichiita kuti ave akakurumbira munzvimbo dzakawanda dzemaindasitiri.
Mhando dzePneumatic Actuators
1. Vharuvhu yebhora yepneumatic
Mavharuvhu Ebhora Emagetsi EmagetsiAkagadzirwa nedhisiki rakatenderera (bhora) kuti adzore kuyerera kwemvura kuburikidza nevharuvhu. Kana bhora rikatenderera nemadhigirii makumi mapfumbamwe, rinobvumira kana kudzivirira kuyerera kwemvura. Mavharuvhu aya anozivikanwa nekugona kwawo kuvhara zvakanaka uye kuderera kushoma kwekumanikidzwa, zvichiita kuti akwanise kushandiswa uchishandisa mvura ine kumanikidzwa kwakanyanya.
Mavharuvhu ebhora anoshandiswa zvakanyanya muindasitiri yemafuta negesi, yekupa mvura uye yekugadzira makemikari. Mavharuvhu ebhora anokurumidza kushanda, anogara kwenguva refu uye ndiwo sarudzo yekutanga kune mashandisirwo ekudzora anobatidza/adzima.
2. Vharuvhu yeshavishavi yemhepo
Mavharuvhu emashavishavi anoshandisa dhisiki rinotenderera kudzora kuyerera kwemvura. Dhisiki iri rakaiswa pashaft uye rinogona kutenderedzwa kuti rivhure kana kuvhara vharuvhu.Mavharuvhu eshavishavi ePneumatic actuatorzvinobatsira zvikuru mukushandiswa kunoda kuyerera kwakanyanya uye kudzikiswa kwesimba remagetsi kwakaderera.
Mavharuvhu aya akareruka uye madiki, zvichiita kuti akwanise kuiswa munzvimbo dzisina nzvimbo yakawanda. Nekuda kwekushanda kwawo zvakanaka uye nyore kugadzirisa, anoshandiswa zvakanyanya muHVAC systems, mafekitori ekuchenesa mvura, uye maindasitiri ekugadzira chikafu.
3. Vharuvhu yegedhi remhepo
Mavharuvhu egedhi akagadzirwa kuti ape nzira yakatwasuka yekuyerera, zvichideredza kurasikirwa nekumanikidzwa. Anoshanda nekusimudza gedhi kubva munzira yekuyerera, zvichiita kuti mvura ifambe zvizere kana yakavhurika.Mavharuvhu egedhi anoshandiswa nemhepoanowanzo shandiswa mumabasa anoda chisimbiso chakasimba, senge masisitimu emvura nemapaipi emafuta.
Kunyange hazvo mavharuvhu egedhi asina kunaka pakushandisa throttling, anonyatsogona pakushandisa on/off control. Magadzirirwo awo akaomarara uye kugona kwawo kutsungirira kumanikidzwa kwakanyanya zvinoita kuti akwanise kushandiswa mumaindasitiri akasiyana-siyana.
4. Vharuvhu yeguruva remagetsi rinoshandisa simba remhepo
Vharuvhu yeglobe ine muviri wakatenderera uye inoshandiswa pakukwenya. Dhisiki iyi inofamba yakatwasuka kuenda kunzira yemvura, zvichiita kuti ikwanise kudzora kuyerera kwayo. Vharuvhu yeglobe inofambiswa nemhepo inowanzo shandiswa mumabasa akakosha ekudzora kuyerera kwemvura, akadai semasisitimu emhepo uye kugadzirisa makemikari.
Mavharuvhu aya anopa kudzora kuyerera kwakanaka uye akakodzera kushandiswa pakumanikidzwa kwakanyanya. Zvisinei, anogona kuderedzwa zvakanyanya kumanikidzwa kupfuura mamwe marudzi emavharuvhu, zvichiita kuti asakodzere kushandiswa kusingadi kudziviswa zvakanyanya.
5. Vharuvhu yeSDV (vharuvhu yekudzima)
Mavharuvhu ekudzivirira (SDVs) zvishandiso zvakakosha zvekuchengetedza zvinoshandiswa mumaindasitiri akasiyana-siyana kudzivirira kufamba kwezvinhu zvine njodzi panguva yenjodzi kana kugadziriswa. Mavharuvhu eSDV anofambiswa nemhepo akagadzirwa kuti avhare nekukurumidza uye zvakachengeteka, zvichiita kuti kufamba kumire nekukurumidza kana zvichidikanwa.
Mavharuvhu aya anowanzo shandiswa munzvimbo dzinoshandiswa mafuta negesi, mafekitori emakemikari, nedzimwe nzvimbo dzine njodzi huru. Kuvimbika kwawo uye nguva yekupindura nekukurumidza zvinoita kuti ave akakosha pakuchengetedza kuchengetedzeka uye kutevedzera mitemo yeindasitiri.
Kushandiswa kweVharuvhu yePneumatic Actuator
Mavharuvhu anoshandiswa nemhepo anoshandiswa mumaindasitiri akasiyana-siyana nekuda kwekushanda kwawo nesimba uye kugona kwawo. Mamwe mashandisirwo akajairika anosanganisira:
- Kugadziriswa kweMakemikoro: Mavharuvhu anoshandiswa nemhepo anoshandiswa kudzora kufamba kwemakemikari muma reactors, ma mixers nematangi, zvichiita kuti pave nechokwadi chekuti mushonga wacho wanyatsogadzirwa uye wasanganiswa.
- Oiri neGasi: Mavharuvhu aya anoita basa guru mukudzora kufamba kwemafuta asina kucheneswa, gasi rechisikigo, uye zvigadzirwa zvakanatswa mumapaipi nenzvimbo dzekugadzirisa.
- Kurapa Mvura: Zvivako zvekuchenesa mvura zvinoshandisa mavharuvhu anoshandiswa nemhepo kudzora kufamba kwemvura nemakemikoro anoshandiswa pakuchenesa.
- Masisitimu eHVAC: Mumasystem ekudziyisa, ekufema, uye emhepo inotonhodza, mavharuvhu aya anobatsira kudzora kufamba kwemhepo nekupisa, nokudaro zvichivandudza kushanda zvakanaka kwesimba uye kunyaradzwa.
- Chikafu neChinwiwa: Mavharuvhu anoshandiswa nemhepo anoshandiswa mukugadzira chikafu kuti ave nechokwadi chekuti zvinoshandiswa nezvigadzirwa zvinobatwa zvakachengeteka uye zvinobudirira.
mukupedzisa
Mavharuvhu anofambiswa nemhepochinhu chakakosha mumabasa emazuva ano emaindasitiri, zvichipa kudzora kwakavimbika uye kunoshanda kwekufamba kwemvura negasi. Mavharuvhu anofambiswa nemhepo anowanikwa mumhando dzakasiyana-siyana, kusanganisira mavharuvhu ebhora, mavharuvhu ebhururu, mavharuvhu egedhi, mavharuvhu epasi, uye mavharuvhu eSDV, zvichibvumira maindasitiri kusarudza sarudzo yakakodzera kushandiswa kwavo. Kunzwisisa hunhu hwakasiyana uye mabhenefiti erudzi rumwe nerumwe rwevharuvhu inofambiswa nemhepo kwakakosha pakuvandudza mashandiro uye kuona kuti mashandiro emaindasitiri akachengeteka. Sezvo tekinoroji ichiramba ichifambira mberi, basa remavharuvhu anofambiswa nemhepo mukuvandudza kushanda zvakanaka kwemaitiro uye kuvimbika richave rakakosha zvakanyanya.
