24V - ngesisekelo amandla nesilinganiso izinhlelo

Ngesikhathi nhliziyo ukunikezela kagesi uhlelo wokulinganisa lamanje ugesi 24V. Ngaphandle kweqhaza isici akunakwenzeka ukusebenza iyiphi iluphu. yokusebenza kwalo isimiso simiswe ngalendlela lelandzelako: zonke izinto zobuchwepheshe ziqoqwa ngokulandelana kwelinye indandatho enkulu, okuyinto ukhiphela wamanje (ngokuvamile a 4-20 ma). I kwamandla kuyinto 24 V umthombo voltage. Inani lamanje inzwa izinguquko kuye ipharamitha. Esikhathini okokufaka analog ukhonza njengoba umamukeli isilawuli ezimbonini. Kulokhu okungenhla kuyacaca ukuthi kusukela eliphezulu yayo kanye nokusebenza okunokwethenjelwa incike ekusebenzeni kwe nezinye izingxenye uhlelo.

shemotehnicheskogo ukuqaliswa

Ukwakheka iyiphi idivayisi ezifana kuhlanganisa amamojula ezilandelayo:

• Fuse link.
• Shiya phansi transformer.
• Diode ibhuloho.
• Hlunga.
• control unit.

Fuse - fuse, esivikela kudivayisi ngokumelene sindisa. Uma uvo elamanje okusezingeni eliphezulu, uzovutha phandle, okubangela wonke Uhlelo uyeke nginomdlandla. Kulokhu, zonke izingxenye ezisele tekusebenta. A transformer siqukethe ohlobo ezimbili. Eyokuqala wabo - iyona eyisisekelo (yayisetshenziswa 220), kanye nezinye - lesibili, okuyinto uphendulela 24B. Okungukuthi, wayemane nje kwehlisa voltage. Diode ibhuloho isignali ac kwenza unomphela. Hlunga kuzole yonke nemingcele komkhiqizo ngenxa yokuphutha bushelelezi iyehla iyenyuka ahlukahlukene. Uphiko wokugcina - control unit - ingatholwa amadivayisi ezinjalo azizintsha njengoba amandla supply 24V. Kukala amasignali okukhiphayo. Uma they sondela ingafinyeleleki, de-anika loop zamanje. Ngesikhathi esifanayo, lesi simo inakekelwa nje ukubaluleka kwabo akuvumelani ukubuyela esimweni esivamile.

izici lobuchwepheshe

• Umkhawulo okukhipha zamanje.
• Umthamo ugesi.
• Isibalo iziteshi okukhiphayo.
• Yokungena Ukuvikelwa.
• Mount Uhlobo.
• Operational lokushisa ububanzi.

Eyokuqala nemingcele ezimbili zihlobene kakhulu. Ngokwesibonelo, uma elivunyelwe okukhipha zamanje 22mA, amandla iyunithi ngeke ukufika kuzo ngaleso sikhathi 5.28 Watts (22 ma iphindwe 24, lamanje ukuze voltage). Ukunciphisa isikhala, okuyinto waziphatha amadivayisi anjalo esikhathini amakhabethe sokulinganisa, basebenzisa imithombo imizila. It ulungisiswa ezimweni lapho uhlelo iqukethe sebuningini nesilinganiso nemingcele. Zokufaka okhonjiswe izinhlamvu «IP» futhi Inkomba zezinombolo. Ayanda njengoba linjalo, njengeliyiZwi konke ivikeleke kakhulu ngaphakathi ivikelwe. Lokhu value kuyadingeka ukuze banake uma ezosebenza ezindaweni nobutha (isib, amakhemikhali noma izimboni Metallurgical). Ngu uhlobo nokubopha amadivayisi abanjalo bangabaphostoli ezimbili zama: isikulufa futhi Din wesitimela obandayo. Eyokuqala wabo - kuyinto ukulungiswa eziphelelwe yisikhathi kancane kancane aphume ukusetshenziswa. Laba ogibele yokubeka ekhethekile, nokuthi namuhla isibe de empeleni waba okujwayelekile. Umngcele we-zokugcina, lapho ephawula kwamandla 24B - uhla okushisa yokusebenza. Kuyadingeka ukuba sinake kuphela uma uhlela ukuqhuba kwezinye izimo ezimbi kakhulu (isibonelo, lapho inani lale ipharamitha angehla lokususa 40-50 degrees Celsius).

Kanjani ukukhetha?

Ukukhetha i-algorithm amadivayisi olunjalo lulandela. Ukucacisa inombolo yokuthi kunezigidi zabasebenzisi kanye umthamo wabo Imininingwane. Lokucabanga kulindeleke ukuba asebenze nge ezinamandla Solenoid valve ukuba 100W futhi zamanje umthwalo isiqongo 5A. Kunconywa ukuthatha amandla inqolobane-20%. Ukuze wenze lokhu, nande ngu 1.2 100W, 120W uthole - amandla, okubonisa ukuthi amandla ethu supply 24V 5A (120W / 24V) kuyoba nje ukusebenza enjalo. Kungenxa yokuthi amadivayisi nge izici okufanele akhethwe. Okulandelayo, udinga ukuba acabangele izimo yokusebenza lokushisa, uma kunesidingo.

Kufinyeta

24V - lena ingxenye ebaluleke kakhulu yesimanje ezishintshayo izinhlelo. Ngaphandle kwawo akunakwenzeka ukuqedela umsebenzi yiluphi uhlelo wokulinganisa namuhla. Ngu abalithandayo kufanele wasondela kahle kakhulu. Endabeni ka zokugwema ukuphuka yengxenye enjalo kungaholela umonakalo kanye nezinye izingxenye uhlelo.
