Vharuvhu yeTWS kubva kuTianjin, China

Mazwi Akakosha:Chinja chemuganho wemakanika; Chinja chemuganho wepedyo

1. Chinja chemuganho wemakanika

Kazhinji, rudzi urwu rweswitch runoshandiswa kudzikamisa nzvimbo kana kurovera kwekufamba kwemuchina, kuitira kuti muchina unofamba ugone kumira wega, kudzosera kumashure, kufamba kwekukurumidza kwakasiyana-siyana kana kufamba otomatiki zvichienderana nenzvimbo kana kurovera. Inosanganisira musoro wekushanda, sisitimu yekubata uye imba. Yakakamurwa kuita direct-action (bhatani), rotary (rotary), micro-action uye combination.

Switch yemuganho inoshanda zvakananga: musimboti wekuita wakafanana nebhatani, musiyano ndewekuti rimwe rinoitwa nemaoko, uye rimwe rinobonderana nebhampa rechikamu chinofamba. Kana chivharo cheinjini chiri pachikamu chinofamba chekunze chikadzvanya bhatani kuti chifambise, kana chikamu chinofamba chikabuda, chinobatana chinotangazve kushanda pasi pechishandiso chechitubu.

Chinotenderera chinotenderedza: Kana simbi inomira (collision block) yemuchina unofamba yakadzvanywa paroller ye limit switch, tsvimbo yekutumira inotenderera pamwe chete ne rotating shaft, kuitira kuti cam isundire impact block, uye kana impact block yarova panzvimbo yakati, inosundidzira micro movement. Chinotenderera chinoshanda nekukurumidza. Kana stop iron iri paroller yabviswa, return spring inodzosera travel switch. Iyi i single-wheel automatic recovery limit switch. Uye two-wheel rotary type travel switch haigone kupora yoga, uye kana ichivimba nemuchina unofamba kuti ufambe nenzira yakatarisana, iron stopper inobonderana neimwe roller kuti igadzirise.

Chinochinja-chinja chidiki chinobatidzwa nekumanikidzwa. Musimboti waro wekushanda ndewekuti simba rekunze remagetsi rinoshanda pamutsara wekuita kuburikidza nechinhu chinopfuudza (dzvanya pini, bhatani, lever, roller, nezvimwewo), uye mushure mekunge simba raunganidzwa kusvika padanho repamusoro, chiito chekukurumidza chinogadzirwa, kuitira kuti chinogumira pamucheto wemutsara wekuita uye chinogumira chakabatana nekukurumidza kana kubviswa. Kana simba riri pachikamu chinopfuudza rabviswa, mutsara wekuita unogadzira simba rekuita reverse, uye kana kusvetuka kwechikamu chinopfuudza rasvika padanho repamusoro rekuita kwemutsara, chiito chekudzoka chinopedzwa ipapo ipapo. Daro rekubata remutsara wechidiki diki, kusvetuka kwekuita kupfupi, simba rekudzvanya diki, uye kudzima kunokurumidza. Kumhanya kwekubata kwekubata kwayo kwekufamba hakuna chekuita nekumhanya kwekubata kwechinhu chinopfuudza. Rudzi rwekutanga rwemutsara wechidiki imhando yepini yekusundidzira, iyo inogona kuwanikwa kubva kumhando yebhatani pfupi yekurovera, mhando yebhatani guru rekurovera, mhando yebhatani rakawanda rekurovera, mhando yebhatani rekurovera, mhando yerori rekurovera, mhando yerori rekurovera, mhando yerori rekurovera, mhando yerori rekurovera, mhando yeruoko rupfupi, mhando yeruoko rurefu nezvimwewo.

Chinochinjisa vharuvhu chemakanika chinowanzo tora chichinjiso chidiki chekubatana kusingashande, uye chimiro chechichinjiso chinogona kukamurwa kuita: danda rimwe chete rinokanda kaviri SPDT, danda rimwe chete rinokanda SPST, danda kaviri rinokanda kaviri DPDT.

2. Chinja chemuganhu wekuswedera pedyo

Chinochinja chepedyo, chinozivikanwawo sechinochinja chekufamba chisina kubatana, hachingogone kutsiva chinochinja chekufamba nechinangana chete kuti chigadzirise kufamba uye chidzivirire miganhu, asiwo chinoshandiswa pakuverenga zvakanyanya, kuyera kumhanya, kudzora huwandu hwemvura, kuona saizi yezvikamu, kubatana otomatiki kwemaitiro ekugadzirisa. Nekuti ine hunhu hwechinochikonzera chisina kubatana, kumhanya kwekuita nekukurumidza, chiito mukati memadaro akasiyana ekuona, chiratidzo chakagadzikana uye chisina pulse, basa rakagadzikana uye rakavimbika, hupenyu hurefu, kurongeka kwenzvimbo dzakadzokororwa zvakanyanya uye kuchinjika kunzvimbo dzakaoma dzekushanda, nezvimwewo, saka chinoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri senge zvishandiso zvemuchina, machira, kudhinda, uye mapurasitiki.

Maswichi ekuswedera pedyo akakamurwa zvichienderana nepfungwa yekushanda: kunyanya mhando ye oscillation ine frequency yakakwira, mhando yeHall, mhando ye ultrasonic, mhando ye capacitive, mhando ye differential coil, mhando ye permanent magnet, nezvimwewo. Rudzi rwemagineti rusingaperi: Runoshandisa simba rekusveta remagineti risingaperi kufambisa reed switch kuti ibudise chiratidzo.

Rudzi rwe coil rwakasiyana: Inoshandisa eddy current uye shanduko ye magnetic field inogadzirwa kana chinhu chaonekwa chasvika, uye inoshanda kuburikidza nemusiyano uripo pakati pe detection coil ne comparison coil. Capacitive proximity switch: Inonyanya kuumbwa ne capacitive oscillator ne electronic circuit. Capacitance yayo iri pa sensing interface. Kana chinhu chasvika, chinozotenderera nekuda kwekuchinja coupling capacitance value, nokudaro chichigadzira oscillation kana kumisa oscillation kuti igadzire output signal. kuchinja kwakawanda. Hall proximity switch: Inoshanda nekushandura magnetic signals kuita electrical signal output, uye output yayo ine memory retention function. Internal magnetic sensitive device inongoteerera magnetic field perpendicular kumagumo kwe sensor. Kana magnetic pole S yakatarisana ne proximity switch, output ye proximity switch ine positive jump, uye output yacho yakakwira. Kana magnetic pole N yakatarisana ne proximity switch, output yacho yakaderera.

Chinja cheUltrasonic proximity: Chinonyanya kuumbwa nema piezoelectric ceramic sensors, zvishandiso zvemagetsi zvekutumira mafungu e ultrasonic uye kugamuchira mafungu anoratidzwa, uye mabhurogu anodzorwa nepurogiramu ekugadzirisa nzvimbo yekuona. Yakakodzera kuona zvinhu zvisingakwanise kana kusagona kubatwa. Basa rayo rekudzora harikanganiswi nezvinhu zvakaita seruzha, magetsi, uye chiedza. Chinangwa chekuona chinogona kuva chinhu chiri mumamiriro akaoma, emvura kana eupfu, chero bedzi chichigona kuratidza mafungu e ultrasonic.

Swichi yekukurumidza kutenderera kwemhepo: Inokonzerwa nesimbi, ine zvikamu zvitatu: oscillator ine frequency yakakura, circuit yakabatanidzwa kana transistor amplifier uye mudziyo wekuburitsa. Nheyo yayo inoshanda ndeiyi: coil ye oscillator inogadzira simba remagineti rinochinjana pamusoro pechinobatika che switch, kana chinhu chesimbi chasvika pamusoro pechinobatika, eddy current inogadzirwa mukati mechinhu chesimbi inotora simba re oscillator, zvichiita kuti oscillator imire kudedera. Zviratidzo zviviri zve oscillation uye vibration stop zve oscillator zvinoshandurwa kuita zviratidzo zve binary switching mushure mekuumbwa uye kuwedzerwa, uye zviratidzo zvekudzora switching zvinobuda.

Chinovhara vharuvhu chemagnetic induction chinowanzo tora electromagnetic induction proximity switch ye passive contact, uye fomu rekuchinja rinogona kukamurwa kuita: single pole double throw SPDT, single pole single throw SPSr, asi hapana double pole double throw DPDT. Chinovhara magnetic induction chinowanzo kamurwa kuita 2-waya dzinovhurika kana dzinogara dzakavharwa, uye 3-waya dzakafanana ne single-pole double-throw SPDT, isina kuvhurika uye inowanzo vharika.
