Vavu ya TWS yochokera ku Tianjin, China

Mawu Ofunika Kwambiri:Makina osinthira malire; Kusintha malire oyandikira

1. Makina osinthira malire

Kawirikawiri, kusintha kwamtunduwu kumagwiritsidwa ntchito kuchepetsa malo kapena kupwetekedwa kwa kayendedwe ka makina, kotero kuti makina oyendetsa amatha kuyimitsa, kusuntha, kusuntha kwachangu, kapena kubwereza kubwereza malingana ndi malo enaake kapena sitiroko. Imakhala ndi mutu wogwirira ntchito, makina olumikizirana komanso nyumba. Amagawidwa mwachindunji-kachitidwe (batani), kugudubuza (rotary), micro-action ndi kuphatikiza.

Kusintha malire molunjika: mfundo yochitapo kanthu ndi yofanana ndi ya batani, kusiyana kwake ndikuti imodzi ndi yamanja, ndipo ina imagundana ndi bumper ya gawo losuntha. Pamene chipika chokhudza mbali yosuntha yakunja chikukankhira batani kuti kukhudzana kusuntha, pamene gawo losuntha lichoka, kukhudzana kumayambiranso pansi pa zochitika za masika.

Kusintha kwa malire: Pamene chitsulo choyimitsa (kugundana) cha makina osuntha chikukanikizidwa pa chosinthira chosinthira malire, ndodo yotumizira imazungulira pamodzi ndi shaft yozungulira, kotero kuti cam imakankhira chipikacho, ndipo pomwe chotchinga chimagunda. imagunda malo enaake, imakankhira micro movement Kusinthana kumagwira ntchito mofulumira. Pamene chitsulo choyimitsa pa chogudubuza chikuchotsedwa, kasupe wobwereranso amatsitsimutsanso kusintha kwaulendo. Ichi ndi gudumu limodzi lodziwikiratu kuchira malire switch. Ndipo masinthidwe oyenda amtundu wa mawilo awiri sangangochira, ndipo ikadalira makina osuntha kupita kwina, choyimitsa chitsulo chimagunda mu chogudubuza china kuti chibwezeretse.

Chosinthira chaching'ono ndi chosinthira mwachangu chomwe chimayendetsedwa ndi kukakamizidwa. Mfundo yake yogwirira ntchito ndi yakuti mphamvu yamakina akunja imagwira ntchito pa bango lochitapo kanthu kudzera mu chinthu chotumizira (pini yosindikizira, batani, lever, roller, etc.), ndipo mphamvuyo itasonkhanitsidwa mpaka pamalo ovuta, nthawi yomweyo imapangidwa. kuti kukhudzana kosuntha kumapeto kwa bango lochitapo kanthu Mfundo ndi kukhudzana kokhazikika zimagwirizanitsidwa mwamsanga kapena kuchotsedwa. Mphamvu pa chinthu chopatsirana ikachotsedwa, bango lochitapo kanthu limatulutsa mphamvu yosinthira, ndipo kugunda kwapambuyo kwa chinthu chopatsirana chikafika pachimake chovuta cha bango, chosinthiracho chimatha nthawi yomweyo. Mtunda wolumikizana ndi chosinthira chaching'ono ndi chaching'ono, sitiroko yochitapo kanthu ndi yayifupi, kukakamiza kumakhala kochepa, ndipo kuyimitsa kumakhala kofulumira. Kuthamanga kwaposachedwa kwa kukhudzana kwake kulibe chochita ndi liwiro la chinthu chotumizira. Mtundu woyambira wakusintha kwapang'onopang'ono ndi mtundu wa pini, womwe ukhoza kutengedwa kuchokera ku batani lalifupi la mtundu wa sitiroko, batani la mtundu waukulu wa sitiroko, batani lamtundu wowonjezera wa sitiroko, mtundu wa batani lodzigudubuza, mtundu wa bango, mtundu wa lever, mtundu wamkono wamfupi, mkono wautali. mtundu etc.

Makina osinthira valavu amatengera kusinthana kwapang'onopang'ono, ndipo mawonekedwe osinthira amatha kugawidwa kukhala: mzati umodzi woponya SPDT, mzati umodzi woponya SPST, mizati iwiri yoponya DPDT.

2. Kuyandikira malire switch

Kusinthana kwapafupi, komwe kumadziwikanso kuti chosinthira chosalumikizana, sikungangosintha kusinthana ndi kulumikizana kuti kumalize kuwongolera kuyenda ndi chitetezo cha malire, komanso kugwiritsidwa ntchito powerengera kwambiri, kuyeza liwiro, kuwongolera kwamadzimadzi, kuzindikira kukula kwa gawo, kulumikizana basi. processing ndondomeko dikirani. Chifukwa ili ndi mawonekedwe a choyambitsa chosalumikizana, kuthamanga kwachangu, kuchitapo kanthu mkati mwa mtunda wodziwikiratu, chizindikiro chokhazikika komanso chosasunthika, ntchito yokhazikika komanso yodalirika, moyo wautali, kubwereza kobwerezabwereza kulondola komanso kusinthika kumadera ogwirira ntchito ovuta, etc., kotero Amagwiritsidwa ntchito kwambiri popanga mafakitale monga zida zamakina, nsalu, kusindikiza, ndi mapulasitiki.

Masiwichi oyandikira amagawidwa molingana ndi mfundo yogwirira ntchito: makamaka mtundu wamtundu wanthawi yayitali, mtundu wa Hall, mtundu wa akupanga, mtundu wa capacitive, mtundu wa koyilo wosiyana, mtundu wa maginito okhazikika, ndi zina. yendetsani bango losinthira kuti litulutse chizindikiro.

Mtundu wa coil wosiyana: Imagwiritsa ntchito mphamvu ya eddy komanso kusintha kwa mphamvu ya maginito yomwe imapangidwa pamene chinthu chodziwika chikuyandikira, ndipo imagwiritsa ntchito kusiyana pakati pa koyilo yozindikira ndi koyilo yofananitsa. Capacitive proximity switch: Imapangidwa makamaka ndi capacitive oscillator ndi dera lamagetsi. Capacitance yake ili pa sensing mawonekedwe. Pamene chinthu chayandikira, izo oscillate chifukwa kusintha lumikiza capacitance mtengo, potero kutulutsa oscillation kapena kuletsa oscillation kupanga linanena bungwe chizindikiro. kusintha kochulukira. Kusintha kwapafupi ndi Hall: Imagwira ntchito potembenuza maginito maginito kuti ikhale yotulutsa magetsi, ndipo kutulutsa kwake kumakhala ndi ntchito yosunga kukumbukira. The mkati maginito tcheru chipangizo amangomvera maginito munda perpendicular kwa mapeto a sensa. Pamene maginito pole S ikuyang'anizana ndi kusinthana kwapafupi, kutuluka kwa kusintha kwapafupi kumakhala ndi kulumpha kwabwino, ndipo kutulutsa kwake kumakhala kwakukulu. Ngati maginito pole N ikuyang'anizana ndi kusinthana kwapafupi, zotsatira zake zimakhala zochepa. mlingo.

Akupanga moyandikana lophimba: Iwo makamaka wopangidwa ndi piezoelectric ceramic masensa, zipangizo zamagetsi kufalitsa akupanga mafunde ndi kulandira unanyezimira mafunde, ndi pulogalamu-olamulidwa mlatho masiwichi kwa kusintha kudziwika osiyanasiyana. Ndizoyenera kuzindikira zinthu zomwe sizingakhudze kapena sizingakhudze. Kuwongolera kwake sikusokonezedwa ndi zinthu monga phokoso, magetsi, ndi kuwala. Chandamale chodziwikiratu chikhoza kukhala chinthu cholimba, chamadzimadzi kapena chaufa, bola chikhoza kuwonetsa mafunde akupanga.

High-frequency oscillation proximity switch: Zimayambitsidwa ndi zitsulo, zomwe zimapangidwa ndi magawo atatu: oscillator othamanga kwambiri, ozungulira ophatikizika kapena transistor amplifier ndi chipangizo chotulutsa. Mfundo yake yogwirira ntchito ndi: koyilo ya oscillator imapanga maginito osinthasintha pamtunda wosinthika, pamene chinthu chachitsulo chikuyandikira pamwamba, eddy yomwe imapangidwa mkati mwa chinthu chachitsulo idzatenga mphamvu ya oscillator, kuchititsa oscillator kuti asiye kunjenjemera. Zizindikiro ziwiri za oscillation ndi vibration stop za oscillator zimasinthidwa kukhala zizindikiro zosinthira binary pambuyo popangidwa ndi kukulitsidwa, ndipo zizindikiro zowongolera zimatuluka.

Kusintha kwa malire a maginito olowetsa ma valve nthawi zambiri kumatenga chosinthira choyandikira chamagetsi chamagetsi, ndipo mawonekedwe osinthira amatha kugawidwa kukhala: mzati umodzi woponyera SPDT, mzati umodzi woponya SPSr, koma palibe mizati iwiri yoponya DPDT. Maginito olowetsa maginito nthawi zambiri amagawidwa mu 2-waya nthawi zambiri yotseguka kapena yotsekedwa, ndipo waya wa 3 ndi ofanana ndi single-pole-kuponya SPDT, osatsegula komanso kutsekedwa kawirikawiri.
