Chii chinonzi solenoid valve?
Dhiagiramu yevharuvhu yeinjini inopisa mukati uye chiratidzo chayo
La solenoid valve Inowanikwa muhuwandu hweazvino masisitimu, kubva mufiriji maseketi kuenda kumota, kuburikidza nekuisa gasi, nezvimwe. Ichi chishandiso chinokwanisa kushandirwa nenzira ye thermostatic switch, relays, nezvimwewo, kureva kuti, inoshanda nemagetsi. Basa rayo nderekudzora kuyerera kwezvinwiwa kana magasi nekuvhura kana kuvhara vharuvhu kuti ibvumidze nzira kana kuti kutsika kwemvura yakataurwa. Mune mamwe mazwi, imhando yepombi inoshandiswa nemagetsi.
Rudzi urwu rwevharuvhu runosanganisira Zvikamu zviviri basic drive:
- Solenoid: Icho chishandiso chiri muchimiro chekoiri yemagetsi (waya yemhangura yakasungirirwa uye yakavharirwa) inokwanisa kugadzira magineti mukati. Munda uyu wakanyanya kusimba mukati uye kunze hauna simba, uchiita magineti emagetsi anokwanisa kumutsa kana kudzora chimwe chinhu (inokwezva simbi dzine simbi), apa kuvhurwa kana kuvhara kwevharuvhu. Muchokwadi, iyi solenoid inowanzonzi mushandisi.
- Muviri wevhavha: Mushandi achaiswa pairi, uye mukati memuviri uyu muchava nepiston yekuvhura kana yekuvhara iyo mushandisi achaita. Uye inogadzirwa ne:
- Plunger (inonziwo tsono kana stem): kana magnetic field inogadzirwa, plunger ichakwezvwa nechepakati pe solenoid uye valve inovhura uye inobvumira kuti mvura ipfuure. Kana pasina magnetic field iri kushandiswa, plunger icharamba yakavharwa uye haibvumiri kuti mvura ipfuure.
- Puerto: igomba rinoyerera mvura kana gasi kana rakavhurika.
Solenoid valve inoshanda sei?
Iyo solenoid valve ine a Yakareruka nheyo yekushanda. Ini ndakatotaura pamusoro peizvi muchikamu chakapfuura, asi ikozvino ngationei nhanho-ne-nhanho maitiro:
- Iyo solenoid valve inoramba yakavharwa kana solenoid isiri kupihwa simba. Nenzira iyi, hapana simba remagineti kana simba rinokwezva rinogadzirwa mairi. Huremu hweplunger hunoita kuti iwire pasi negiravhiti uye kuvhara gomba, kureva kuti, plunger iri pakuzorora uye hapana kuyerera kunobvumidzwa.
- Kana iyo solenoid yave nesimba, tsono inosungirirwa pasi pepunga inosimudza sezvo magnetic field inosimudza plunger kumusoro uye plunger inodhonzawo patsono, ichiisa pachena gomba uye ichibvumira kuyerera.
Nekudaro, mamwe marudzi emavharuvhu anoshanda zvishoma zvakasiyana, seaya anoshandisa zvitubu kana zvitubu kusunda plunger kuvhara valve. Izvi zvinobvumira mavharuvhu kuti aiswe munzvimbo dzisiri dzakamira (kuita negiravhiti).
Kana iwe ukashamisika iyo solenoid inogona kushandiswa sei, Zviri nyore chaizvo. Inodyiswa nemagetsi emagetsi uye izvo zvinogadzira iyo magnetic field. Zvechokwadi, magetsi anogona kudzorwa kuitira kuti atendeuke chete kana kudzima pazvinenge zvichidiwa. Kuti uite izvi, zvinogona kuitwa neshanduko yakapfava yebhurawuza pa/kudzima, kana kuti inogona kunge yakanyanya kuoma uye mhinduro system inoona mamwe mamiriro kuburikidza nema sensors uye inorongedzerwa kuvhura kana kuvhara valve zvichibva pane izvo.
Kubatsirwa
Iyo solenoid valve ine zvimwe zvakanaka Chii chinofanira kucherechedzwa:
- Vakachengeteka: Mamwe mamwe mavharuvhu anogona kuburitsa kuvuza nekuda kwekunyanya kudzvanywa, kupfeka, kukanganisa kwekuisa, nezvimwe. Uye kana uchishanda nemvura inopfuta, ine chepfu, inoparadza, nezvimwewo, zvinogona kuva nengozi. Mune solenoid valve, iyo inopinza uye yekubuda madoko inogona kuvharika zviri nyore munjodzi.
- Kukurumidza chiito: Kutenda kune mavharuvhu aya, kuyerera kunogona kuregedzerwa kana kugurwa mune imwe nyaya yemamilliseconds. Izvo zvinobvumira kudzora kuyerera kuri nani.
- Kuvimbika: Kuve iri nyore sisitimu, ivo vanowanzo gara uye haatomboda gadziriso. Mukuwedzera, zvakachipa uye unogona kuzviwana muhukuru hwakasiyana kuti uenderane nemapombi kana machubhu e hydraulic, pneumatic, nezvimwe.
- Otomatiki: Vanobvisa kudiwa kwedhiraivha yekudzora kuyerera, uye izvo zvinoita kuti zvive zvakanyatsojeka.
- Nyore: kuisa uye purogiramu.
Applications
Kana iwe uri kushamisika chii chinonzi solenoid valve, Heano mamwe akajairika mashandisirwo emidziyo iyi muhydraulic (mvura yemvura) uye pneumatic (gasi remvura) maseketi:
- Fluid pressure control
- Kudzora tembiricha inobatanidzwa
- Fluid Viscosity Control
Solenoid valve mhando
Mumwe mubvunzo unowanzo bvunzwa ndewekuti chii mhando dzakasiyana dze solenoid valves? Kuti tipindure, ngationei marudzi evharuvhu ye solenoid:
- direct drive: Mhando iyi ye solenoid valves inogona kushanda kunyange pasi pemamiriro ekutsvaira. Ivo ndevekushandisa kushoma, vachingova 10% chete yevashandi. Uye, zvakare, vanogona kuva:
- N/C: Kazhinji Yakavharwa, uko kupa simba solenoid kunoita kuti ivhure uye kusashandisa simba kunoita kuti irambe yakavharwa.
- N/O: Kazhinji Vhura, kureva kuseri kwezviri pamusoro, uko chitubu chinobata vharuvhu kuvhurika kana solenoid isina simba uye inosundidzira yakavharwa kana yasimbiswa.
- Mutyairi wemukati: muzviitiko izvi, solenoid ichashandisa kumanikidzwa kwemukati kuti idzore valve, saka inofanira kushandisa simba shoma remagetsi pane rakapfuura.
- mutyairi wekunze: yakafanana neyo yapfuura, asi shandisa kunze kwekumanikidza kusimudzira kufamba kwevhavha. Izvi zvinobatsirawo solenoid kuitira kuti simba rakawanda risingadiwi.
Nzira yekusarudza yakakodzera solenoid valve
Panguva ye sarudza solenoid valve yakanyanya kukodzera kune zvaunoda, iwe unofanirwa kufunga nezve akati wandei zvinhu:
- Circuit pressure: zvakakosha kuziva kuti kudzvinyirirwa kwedunhu umo vheji ichaiswa ichave, sezvo izvi zvinogona kusarudza rudzi rwevhavha inoshandiswa kuchengetedza simba.
- Sipidhi inodiwa: kumhanya uko vharuvhu inovhura kana kuvhara zvakare chimwe chinhu chakakosha, zvakanyanya kana zvichidikanwa muhurongwa uko kurongeka mukudzora kuyerera kwakakosha. Somuenzaniso, kutyaira kunononoka pane kuita kwakananga.
- N/C vs. N/O: Izvi zvinogona zvakare kukanganisa kushandiswa. Kazhinji, kana mutsara wekuyerera wakavharwa nguva zhinji uye unongoda kuvhurwa nguva nenguva, N / C ndiyo sarudzo yakanaka, sezvo simba kune solenoid rinongoda kushandiswa pane dzimwe nguva. Kana kuyerera kuchiwanzo kuvhurika uye kuchingoda kuvharwa mune dzimwe nguva, ipapo N/O iri nani.
- flow rate: Zvakakosha kutarisa kuyerera kunofanirwa kubatwa kuti uone ukuru hwechiteshi kana nhamba yezvikepe (makomba).
- Size: inofanirawo kuve yakakodzera kugadzwa muhurongwa uye inopindirana nehutema hwepombi.
- Voltage: Iwe zvakare uchawana mavharuvhu ane akasiyana emagetsi maitiro, akadai semagetsi. Izvi zvinofanirwa kuenderana nezvaunoda.
Ehe, rangarira kuti iwe unozoda zvimwe zvekuwedzera zvekuisa kwako, senge zvinongedzo uye inodiwa yemagetsi control circuit, machubhu kana hoses, nezvimwe.
Kupi kutenga yakachipa solenoid valve
