Ngesikhathi sokusebenza kwe-turbine ye-steam kwisitshalo samandla, ukusebenza okujwayelekile komthwalo kubalulekile. Ukushisa okungajwayelekile komthwalo kungaholela emiphumeleni emibi, njengezingozi ezivuthayo, okuthinta ukusebenza okuphephile futhi okuzinzile kwalo lonke i-turbine. Njengento ebaluleke kakhulu yokulinganisa izinga lokushisa, i-Temperature Propecre WZPM2-201 idlala indima engenakufinyeleleka ekuqapheleni kokushisa nokuvikelwa kokuthwala.

I. Izici eziyisisekelo ze-Temperature Prope WZPM2-201

1. Izici zesakhiwo

I-FRESTACT PROCE WZPM2-201 ingukumelana nokushisa okushisayo okuphindwe kabili ngenombolo yokuthweswa iziqu kwe-PT100. Ikwamukela ukwakheka kwe-End-Face Temperature Prope, okunika amandla into yokuzwakala kwezinga lokushisa ukuthi isondele ebusweni bokuphela obulinganisiwe futhi babonise izinga lokushisa ngokuqondile nangokunemba. Isibonelo, ngesilinganiso sokunikezwa kwe-turbine, uphenyo lwayo lungakwazi ukuhambisana eduze komthelela. Imininingwane ingenziwa ngokuya ngokufakwa okuthile kanye nokusebenzisa imvelo ye-turbine. Isakhiwo segatsha ephindwe kabili futhi sandisa ukwethenjwa kwesilinganiso.

2. Izinzuzo zokusebenza

I-FRESTACT PROCE WZPM2-201 inamakhono okulinganisa okushisa okuphezulu. Ebangeni le-0 - 150 ℃ (njengohlu lwendawo yokulinganisa yokushisa yensimbi engu- # 6 yokulinganisa insimbi kanye nephuzu lokulinganisa lokushisa lensimbi ku-600mw thermal amandla generator), ukunemba kokulinganisa kungafinyelela ± 0,15 ℃. Kunokuqina okuphezulu futhi kungagcina ukusebenza okuzinzile endaweni eyinkimbinkimbi yamandla endawo ngesikhathi sokuhlinzwa isikhathi eside. Lokhu kungenxa yokuthi izinto zokumelana neplatinamu ezisetshenzisiwe zinokuqina okuhle kwamakhemikhali futhi azithinteki kalula yizinto ezifana nokungcoliswa kwamafutha kanye nokungcola kwamanzi endaweni yokusebenza ye-turbine.

II. Umgomo Wokusebenza Ekuvikelweni

1. Isimiso sokuhlola izinga lokushisa

Lapho i-turbine isebenza, uphenyo lokushisa kwe-probe ye-WZPM2-201 othintana nabo ebusweni bomthwali, futhi ukushisa komthandela kuzodluliselwa engxenyeni yokufuna kwezinga lokushisa. Ngokwezici zokumelana nokushisa kwezinga lokushisa, njengoba izinga lokushisa elivutha likhuphuka, ukumelana kwe-freen probe kuzoshintsha ngokuya ngejika lesici se-PT100. Isibonelo, lapho izinga lokushisa elithwala likhuphuka lisuka emazingeni okushisa asekamelweni liye ku-100 ℃, ukumelana kwe-PT100 kuzokwanda kusuka ku-100ω kufinyelela ku-138.5ω Ngenxa yalokho.

Lolu shintsho ekumelaneni ludluliselwa ohlelweni lokulawula ngomugqa wesiginali. Isibonelo, kuma-DCS (uhlelo lokulawula olusatshalaliswa), isiginali icutshungulwa yikhadi (njenge-ASI23-6 ne-ASI23-8 Iziteshi) kanye nenani lokushisa langempela le-haring liboniswa kwi-interface yokusebenza.

2. I-Alarm ne-Protection Trigger Mechanism

Ohlelweni lokulawula lweTurbine Turbine, kunenani le-alamu elisethiwe lamazinga okushisa avumayo (njenge-100 ℃ ngesibonelo esingenhla). Lapho inani lokushisa elinganiswa ngumbuso wokushisa kwe-Propher Preform WZPM2-201 lifinyelela noma lidlula leli nani le-alamu, uhlelo lokulawula luzovuselela isinali ye-alamu. Lesi siginali ye-alamu singakhonjiswa esikrinini sokusebenza kwe-DCS, futhi i-alamu ebonakalayo nebonakalayo izokhishwa.

Kwezinye izinhlelo zokulawula ezithuthukile, lapho amazinga okushisa eqhubeka ekhuphuka noma edlula inani eliphakeme elisezingeni eliphakeme, isenzo sokuvikela sizodalwa. Isibonelo, uhlelo lokulawula lunganciphisa ngokuzenzakalela ukuphuza umusi we-turbine, ngaleyo ndlela kunciphise isivinini nokulayisha i-turbine ye-steam ukuze kunciphise ukushisa kokuvutha nokuvuka okuqhubekayo.

III. Amaphoyinti wokufaka kanye nokuvikelwa kuzinhlelo zokusebenza ezisebenzayo

1. Isikhundla sokufaka nendlela

Ekufakweni kwe-turbine beth, ukufunwa kwezinga lokushisa i-WZPM2-201 kuvame ukulungiswa kwibhlokhi eliphansi eliphansi ngokucindezela. Isibonelo, ku-600mmw Forrmal Power Generator, into yokulinganisa lokushisa ifakwe kahle esimweni esifanelekile sokuthwala ngale ndlela. Isikhundla esinjalo sokufaka singaqinisekisa ukuthi ukuxhumana okuhle phakathi kophenyo kanye nokuthwala ukuze kukala ngokunembile izinga lokushisa lomthelela.

Ngesikhathi sokufakwa, ukunakwa kufanele kukhokhwe kwizikhala ezinezingxenye ezizungezile ukugwema ukuphazanyiswa kwezinye izinto noma kuthinte ukusebenza kwayo okujwayelekile.

2. Izinyathelo zokuvikela

Ngenxa yobunzima bendawo yokusebenza ye-turbine, uphenyo lokushisa lokuvuna ludinga ukuvikelwa okuhle. Ngesikhathi sokufakwa, ukunakekelwa kufanele kuthathwe ukugwema ukuklwebhula noma ukulimala kuholela. Isibonelo, ekusebenzeni kwangempela kwesethi yamandla kagesi ka-600mw we-Thermal, indlela yokuhlelwa komugqa oholayo owamukelwa ekuqaleni kwathathwa ukugqokwa komugqa. Kamuva, ngokuvula kabusha umgodi emzimbeni wokukhala kwamafutha e-oyela, umugqa wokuhola uholele ngqo kusuka phambi komzimba we-pal weal we-pairy, kanye neshubhu le-wax eliphuzi lalisetshenziselwa ukuvikela. Ngasikhathi sinye, kwengezwa iphuzu elinqunyelwe ebangeni elithile (njenge-200mm) ukuvikela umugqa wokuhola kusuka ekujikeni, ukufeza imiphumela emihle.

IV. Umthelela oqhubekayo ekuvikelweni

1. Ukuhlaziywa kwamacala

Ekusebenzeni kwangaphambilini kwesethi ye-600mm ye-Thermal Power Generator esethiwe, amaphutha ahlobene ne-WZPM2-20 eyenzekile. Isibonelo, ngemuva kokuguqulwa kokugeleza kwengxenye, amaphuzu okushisa okushisa a- # 6 no- # 8 wehlulekile ngokulandelana, ikakhulukazi ngenxa yokugqoka komugqa wokuhola oxhumene ne-shaft oilpay piepe kanye nezinye izinto, okuholela ekujikelezeni okuvulekile. Lokhu kuveza izingozi ezifihliwe kwinqubo yokuqamba kanye nokufaka, njengesikhundla esingenangqondo somgodi we-lead-Out Line Hole.

2. Izindlela Zokukhangela kanye nokubaluleka kwazo

Ephendula amaphutha angenhla, umgodi wokuhola wesidumbu sendandatho yamafutha avulwe kabusha ukuze avumele umugqa wokuhola uholele ngqo kusuka phambi komzimba we-weal seal ring. Lesi sixazululo sixazulule ngokuphelele inkinga yokugqoka kocingo okuholayo. Ngemuva kwenguquko, bekulokhu kugijima iminyaka engaphezu kwemibili ngaphandle kweziphambeko, futhi ukunemba kokuqapha amazinga okushisa kuye kwaqinisekiswa ngokuqhubekayo, ngaleyo ndlela kuqinisekiswe ukuphepha kwemithwalo ngesikhathi sokusebenza kweTurbine.

I-Temperatite Probe WZPM2-201 idlala indima ebalulekile ekuvikelweni kwama-turbines wezitshalo zamandla. Ukulinganiswa kwayo okunembile futhi okuthembekile kokushisa, izindlela zokufaka ezinokwethenjelwa kanye nezindlela zokuvikelwa, kanye nesifinyezo esifingqiwe ekuphatheni amaphutha konke okuhlinzeka ngeziqinisekiso eziqinile zokusebenza okuphephile kwamabheyili e-turbine.

Lapho ufuna ikhwalithi ephezulu, yokushisa okuthembekile yokushisa, akungabazeki ukuthi uYoyik ukhetha ukucatshangelwa. Inkampani isebenza ngokukhethekile ekunikezeni imishini ehlukahlukene yamandla kubandakanya izesekeli ze-turbine, futhi ithole isimemezelo esibanzi ngemikhiqizo nezinsizakalo ezisezingeni eliphakeme. Ngeminye imininingwane noma imibuzo, sicela uxhumane nensizakalo yamakhasimende ngezansi:
