1. Umkhiqizo Uphelileview
I-Johnson Controls EP-8000-3 iyi-transducer ye-electro-pneumatic eyenzelwe ukuguqula isignali yokufaka kagesi ejwayelekile ibe isignali yokuphuma kwe-pneumatic ehambisanayo. Ngokukhethekile, yamukela ukufakwa kukagesi okungu-4-20 mA DC futhi ikhiqiza ukuphuma kwe-pneumatic okungu-3-15 PSIG. Le divayisi ibalulekile ezinhlelweni zokulawula zezimboni zokuxhumanisa abalawuli be-elekthronikhi nama-actuator e-pneumatic noma eminye imishini ye-pneumatic. Inokukhishwa kwevolumu ephansi, okuqinisekisa ukulawula okunembile nokuphendulayo.
Lesi sithombe sibonisa i-transducer ye-electro-pneumatic ye-Johnson Controls, ikakhulukazi imodeli ye-EP-8000-2, emele uchungechunge lwe-EP-8000. Iyiyunithi encane, engwevu eyisilinda eyenzelwe ukuguqula izimpawu zikagesi zibe izimpawu zomoya. Izici ezibonakalayo zifaka phakathi igama lomkhiqizo elithi 'JOHNSON CONTROLS', inombolo yemodeli ethi 'EP-8000-2', imininingwane yokufaka/yokukhipha, kanye namaphoyinti okuxhuma esisekelweni.
2. Ulwazi Lokuphepha
Funda futhi uqonde yonke imiyalelo ngaphambi kokufaka, ukusebenzisa, noma ukugcina le divayisi. Ukwehluleka ukulandela le miyalelo kungabangela umonakalo wempahla, ukulimala komuntu, noma ukufa.
- Ukufaka nokusevisa kufanele kwenziwe ngabasebenzi abaqeqeshiwe kuphela.
- Nqamula yonke imithombo kagesi ngaphambi kokufaka izintambo noma ukulungisa i-transducer.
- Qinisekisa ukuthi imigqa yokuphakelwa kwe-pneumatic icindezelwe ngaphambi kokwenza noma ukuphula ukuxhumana.
- Qinisekisa ukuthi indawo yokusebenza ingaphakathi kwamazinga okushisa nomswakama acacisiwe.
- Ungadluli inani eliphakeme kakhulu lokufaka noma ingcindezi yokukhipha.
3. Ukusetha nokufakwa
3.1 Ukukhweza
Faka i-transducer ye-EP-8000-3 endaweni engenakho ukudlidliza ngokweqile, umswakama, kanye namazinga okushisa aphezulu. Qinisekisa ukuthi kunesikhala esanele sokuxhuma izintambo kanye nokuxhumana komoya, kanye nokugcinwa kwesikhathi esizayo. Idivayisi kufanele ifakwe ngokuphephile ukuze ivimbele ukunyakaza ngesikhathi sokusebenza.
3.2 Ukuxhunywa kukagesi
Xhuma isignali yokufaka engu-4-20 mA DC kuma-terminal kagesi aqokiwe. Qaphela i-polarity efanele. Sebenzisa izintambo zokulinganisa ezifanele zohlelo lokusebenza futhi uqinisekise ukuthi zonke izixhumanisi ziphephile ukuvimbela ukusebenza okungapheli noma ukulahleka kwesignali. Bheka ilebula yedivayisi ukuze uthole imisebenzi ethile yama-terminal.
3.3 Izixhumanisi Zomoya
Xhuma ukunikezwa komoya okulawulwayo (ngokuvamile i-PSIG engu-20 ngebanga lokukhipha le-PSIG elingu-3-15) echwebeni lokunikezela. Xhuma umugqa womoya ophumayo echwebeni lokukhipha elibekiwe. Qinisekisa ukuthi zonke izixhumanisi zomoya azivuzi usebenzisa izinto zokufaka ezifanele kanye nezindlela zokuvala. Ukunikezwa komoya kumele kube nomoya wensimbi ohlanzekile, owomile, futhi ongenawo uwoyela.
4. Ukusebenza
Uma isifakiwe kahle futhi ixhunyiwe, i-transducer ye-EP-8000-3 izoguqula isignali kagesi ye-4-20 mA DC engenayo ibe umphumela womoya we-3-15 PSIG ohambisanayo. Ukufakwa kwe-4 mA kuzohambisana nomphumela we-3 PSIG, kanti ukufakwa kwe-20 mA kuzohambisana nomphumela we-15 PSIG. I-transducer isebenza ngokuqhubekayo inqobo nje uma ugesi kanye nokunikezwa komoya kuhlinzekwa.
4.1 Ukulinganisa (uma kusebenza)
Nakuba i-EP-8000-3 ilinganiswa embonini, ukuqinisekiswa njalo kokukhipha kwayo ngokumelene nesignali yokufakwayo eyaziwayo kuyanconywa. Uma kudingeka ukulinganiswa kwensimu, bheka inqubo ethile yokulinganisa echazwe ekhasini eligcwele ledatha yobuchwepheshe noma uxhumane nosekelo lobuchwepheshe lwe-Johnson Controls. Ngokuvamile, ukulinganisa kuhilela ukulungisa izilungiselelo ze-zero kanye ne-span ukuqinisekisa ukuguqulwa okunembile kulo lonke uhla.
5. Isondlo
I-transducer ye-EP-8000-3 yenzelwe ukusebenza okuthembekile ngaphandle kokulungiswa okuningi. Kodwa-ke, ukuhlolwa njalo kungasiza ekuqinisekiseni ukusebenza kahle kanye nobude besikhathi.
- Ukuhlolwa Kwezikhathi: Hlola i-transducer ngamehlo kanye nokuxhumeka kwayo ukuze ubone ukuthi kukhona yini izimpawu zomonakalo, ukugqwala, noma izintambo/amapayipi axegayo.
- Inhlanzeko: Gcina ingaphandle ledivayisi lihlanzekile futhi lingenalo uthuli noma imfucumfucu. Ungasebenzisi amakhemikhali anamandla noma izihlanzi ezihudulayo.
- Ikhwalithi Yokunikezwa Komoya: Qinisekisa ukuthi ukunikezwa komoya kuhlala kuhlanzekile, komile, futhi akunawoyela. Izinto ezingcolisayo zingathinta ukusebenza kwe-transducer kanye nesikhathi sokuphila kwayo.
- Ubuqotho bokuxhumana: Hlola njalo ukuxhumana kukagesi nokwe-pneumatic ukuze kubonakale ukuthi kuqinile.
6. Ukuxazulula izinkinga
Uma i-transducer ye-EP-8000-3 ingasebenzi njengoba kulindelekile, cabangela lezi zinyathelo ezilandelayo zokuxazulula izinkinga:
| Uphawu | Imbangela Engenzeka | Isenzo |
|---|---|---|
| Akukho okukhiphayo komoya | Akukho signali yokufaka kagesi; Akukho ukuphakelwa komoya; Izintambo/amapayipi angasebenzi kahle; Ukwehluleka kwedivayisi | Qinisekisa okokufaka okungu-4-20 mA; Hlola ingcindezi yokunikezwa komoya; Hlola ukuxhumana; Shintsha idivayisi uma kudingeka |
| Ukukhishwa kwe-pneumatic okungalungile | Isignali yokufaka engalungile; Ukuzulazula kokulinganisa; Ingcindezi yokuphakelwa komoya engalungile | Qinisekisa ukunemba kwesignali yokufaka engu-4-20 mA; Hlola ingcindezi yokunikezwa komoya; Yenza ukulinganisa uma kudingeka |
| Umphumela womoya ongazinzile | Isignali yokufaka eshintshashintshayo; Ukunikezwa komoya okungazinzile; Ukuxhumeka okuxegayo; Ukudlidliza | Hlola ukuzinza kwesiginali yokufaka kanye nokunikezwa kwe-pneumatic; Vikela konke ukuxhumana; Nciphisa ukudlidliza uma kungenzeka |
Uma izinyathelo zokuxazulula izinkinga zingaxazululi inkinga, xhumana nosekelo lobuchwepheshe lwe-Johnson Controls ukuze uthole usizo olwengeziwe.
