imikhiqizo

Ikhadi le-MPC4 lokuvikela umshini liyinto emaphakathi ohlelweni lokuvikela umshini we-VM600 (MPS). Leli khadi eliguquguqukayo liyakwazi ukulinganisa nokuqapha okokufaka kwesignali okune okuguquguqukayo kanye nokokufaka kwesivinini okufika kokubili ngesikhathi esisodwa.

Okufakwayo kwesiginali okuguquguqukayo kuyahleleka ngokugcwele futhi kungamukela amasiginali amelela ukusheshisa, isivinini kanye nokugudluka (ukusondela), phakathi kokunye. Ukucutshungulwa kwe-multichannel ebhodini kuvumela ukukalwa kwamapharamitha ahlukahlukene ngokomzimba, okuhlanganisa ukudlidliza okuhlobene nokuphelele, i-Smax, i-eccentricity, indawo ye-thrust, ukunwetshwa okuphelele nokuhluka kwezindlu, ukufuduka kanye nokucindezela okunamandla.

Ukucutshungulwa kwedijithali kuhlanganisa ukuhlunga kwedijithali, ukuhlanganiswa noma ukuhlukanisa (uma kudingekile), ukulungiswa (i-RMS, inani lencazelo, ukuphakama kwangempela noma ukuphakama kweqiniso kuya phezulu), ukulandelela i-oda (i-amplitude nesigaba) kanye nokukalwa kwegebe lenzwa-thagethi.

Okokufaka kwesivinini (i-tachometer) kwamukela amasiginali avela ezinhlobonhlobo zezinzwa zesivinini, okuhlanganisa amasistimu asuselwe kuma-proximity probe, izinzwa kazibuthe ze-pulse pickup noma amasignali e-TTL. Izilinganiso ze-fractional tachometer nazo ziyasekelwa.

Ukulungiselelwa kungavezwa ngamayunithi we-metric noma we-imperial. Isexwayiso kanye nesethi yamaphoyinti e-Danger ayahleleka ngokugcwele, njengokulibaziseka kwesikhathi se-alamu, i-hysteresis kanye ne-latching. Amaleveli Okwazisa Nengozi nawo angashintshwa njengomsebenzi wejubane noma yiluphi ulwazi lwangaphandle.

Okuphumayo kwedijithali kuyatholakala ngaphakathi (ekhadini lokufaka/lokukhiphayo le-IOC4T elihambisanayo) kuleveli ngayinye ye-alamu. Lezi zimpawu ze-alamu zingashayela ama-relay amane asendaweni ekhadini le-IOC4T futhi/noma zingahanjiswa kusetshenziswa ibhasi le-VM600 rack's Raw noma ibhasi le-Open Collector (OC) ukushayela ukudluliselwa kumakhadi okudlulisa ongawakhetha njenge-RLC16 noma i-IRC4.

Amasignali aguquguqukayo (ama-vibration) acutshunguliwe kanye namasignali esivinini ayatholakala ngemuva kwerekhi (kuphaneli yangaphambili ye-IOC4T) njengamasiginali wokuphuma kwe-analog. Amasignali asekelwe ku-voltage (0 kuya ku-10 V) kanye namanje (4 kuya ku-20 mA) anikeziwe. I-MPC4 yenza ukuzihlola yona kanye nohlelo lokuxilonga ekukhuphuleni amandla. Ukwengeza, i-builin "Isistimu ELUNGILE" yekhadi ihlale iqapha izinga lamasiginali ahlinzekwa iketango lokulinganisa (inzwa kanye/noma i-conditioner yesignali) futhi ikhombisa noma iyiphi inkinga ngenxa yomugqa wokudlulisela ophukile, inzwa engalungile noma isibonisi sesignali.

Isibonisi se-LED kuphaneli yangaphambili ye-MPC4 sibonisa ukuthi iphutha lokucubungula noma ihadiwe lenzekile. Ama-LED ayisithupha engeziwe (ishaneli yokufaka eyodwa) akhombisa ukuthi iSistimu OK ithole iphutha nokuthi ngabe i-alamu yenzekile yini esiteshini.

Ikhadi le-MPC4 litholakala ngezinguqulo ezintathu: inguqulo "ejwayelekile", inguqulo "yezifunda ezihlukene" kanye nenguqulo "yokuphepha" (SIL), konke kusebenza njengepheya lekhadi kusetshenziswa ikhadi elihambisanayo le-IOC4T lokufaka/ lokuphumayo. Izinguqulo ezihlukene zekhadi le-MPC4 Ikhadi le-MPC4 litholakala ngezinguqulo ezahlukene, okuhlanganisa "okujwayelekile", "amasekhethi ahlukene" kanye "nokuphepha" (SIL) izinguqulo.

Ngaphezu kwalokho, ezinye izinguqulo ziyatholakala nge-conformal coating esetshenziswa kumjikelezo wekhadi ukuze uthole ukuvikelwa okwengeziwe kwemvelo ngokumelene namakhemikhali, uthuli, umswakama kanye nokushisa okweqile. Kokubili inguqulo 'ejwayelekile' kanye "nezinguqulo zokuphepha" (SIL) zekhadi le-MPC4 zigunyazwe ku-IEC 61508 kanye ne-ISO 13849, ukuze zisetshenziswe kumongo wokuphepha osebenzayo, njenge-SIL 1 ngokuvumelana ne-IEC 61508 kanye ne-PL c ngokuvumelana ne-ISO 13849-1. Ikhadi “elijwayelekile” le-MPC4 liwuhlobo lwangempela futhi lisekela zonke izici nezindlela zokucubungula. I-MPC4 “ejwayelekile” ihloselwe izinhlelo zokuphepha ezisebenzisa irack ye-VM600 enohlu olulinganiselwe lwamakhadi, okungukuthi, “ajwayelekile” amakhadi e-MPC4/IOC4T amakhadi kanye namakhadi adluliselwe e-RLC16. Ine-VMEcompatible isigqila esibonakalayo ngakho-ke isoftware elungisekayo nge-VME uma kunekhadi le-CPUx elisebenza njengesilawuli se-rack ku-VM600 rack. Iphinde ibe yisoftware elungisekayo nge-RS-232 (ephaneli elingaphambili lekhadi).

Ikhadi “lokuphepha” (SIL) MPC4, elaziwa nge-MPC4SIL, lakhiwe ukuze livumele uhla olubanzi lwezinketho zokufaka. Ngokukhethekile, amarack e-VM600 aqukethe namakhadi okuqapha isimo njenge-XMx16 namakhadi adluliselwe njenge-IRC4. Ukuze kuqinisekiswe ukuphepha lokhu kulungiselelwa, bekudingeka ukuqinisekisa ukuthi i-MPC4SIL ihlukanisiwe kwamanye amakhadi ku-VM600 rack, ukuze kungenzeki ukuthi ukucushwa kwayo kulungiswe kungaqondile. Ngakho-ke, ikhadi le-MPC4SIL alibandakanyi i-interface yesigqila ehambisana ne-VME, alisekeli iziteshi ze-tachometer (isivinini) futhi alihlinzeki ngawo wonke amakhono okucubungula isignali ekhadini “elijwayelekile” le-MPC4 (bheka Ukucaciswa okwengeziwe - "okujwayelekile" kanye "namasekhethi ahlukene" amakhadi we-MPC4 ekhasini lesi-9 kuphela). Ukuhlukaniswa kwe-MPS ne-CMS Irack ye-VM600, amakhadi okuvikela imishini, amakhadi okuqapha isimo kanye nesofthiwe ehambisanayo yakhelwe ukuthobelana nesistimu yokuvikela umshini (MPS) kanye nezidingo zokuhlukaniswa kwesistimu (CMS) yezinga le-API 670, eliqinisekisa ukuthi ukusebenza kwe-MPS akuncikile futhi akuphazanyiswa nganoma iyiphi indlela yi-CMS. Ngakho-ke nakuba amakhadi okuvikela imishini namakhadi okuqapha isimo angabelana kalula ngezimpawu zezinzwa ezivela kumaketanga okulinganisa, amapheya ekhadi le-MPC4/IOC4T awabelani nganoma yimaphi amabhasi okuxhumana namapheya ekhadi lokuqapha isimo se-XMx16/XIO16T endaweni yokubeka i-VM600, kanti amapheya ekhadi le-MPC4/IOC4T ayalungiswa futhi asetshenziswa isoftware ye-VXM6 Amapheya wekhadi we-XMx16/XIO16T amisiwe futhi asetshenziswa kusetshenziswa isofthiwe ye-VibroSight®). Imininingwane yezinhlelo zokusebenza Uma isetshenziswa njengepheya lekhadi elinekhadi lokungenayo/lokukhiphayo le-IOC4T, i-MPC4 ifaneleka kakhulu ukuqapha nokuvikela imishini kuzinhlelo eziningi ezihlukene zezimboni. Ukuze uthole ulwazi olwengeziwe mayelana nokusetshenziswa kwamapheya ekhadi le-MPC4/IOC4T ngokuvamile, bheka i-VM600 machinery protection system (MPS) hardware manual kanye ne-VM600 MPSx software manuals. Ukuze uthole ulwazi mayelana nokusetshenziswa kwamapheya ekhadi le-MPC4/IOC4T ezimeni zokuphepha ezisebenzayo, bheka ireferensi yebhukwana lezokuphepha elisebenzayo le-VM600. Ngezinhlelo zokusebenza ezithile, xhumana nomele i-Meggitt yangakini.
