I-Hydraulic iMonti yeStrookeI-Deh-LVDT-300-6 sisifo esiphambili sokulinganisa ukufuduswa kwe-Actsuator Piston kwi-Steam Digital Sydro-Hydraulic Curbility Sydro-ye-Hydraulic (Deh). Yeyohlobo lomgca oguquguqukayo ohlukileyo (i-LVDT). Its core function is to convert the mechanical displacement of the actuator into an electrical signal and feed it back to the control system to achieve precise adjustment of the steam valve of the steam turbine. Inexabiso elibalulekileyo lesicelo kumandla esizukulwana, ipetrochemical kunye namanye amasimi.

UMGAQO-NKQUBO OMPILO

I-hydrake i-pille slrooke sensor deh-lvdt-300-6 yenzelwe ngokusekwe kumgaqo-siseko wokuqulunqwa kwe-elektromagnetic. Inemonka eyintloko, i-coils ezimbini zenqanaba lesibini kunye nesinyithi esishukumisileyo. Xa i-iron core ihamba ne-piston ye-ARDTATOR, umohluko we-voltage one-voltage we-coil enxulumene nokufuduswa, kwaye uluhlu lwe-Instal 0.2-1.5vdc, i-voltage epheleleyo 3.8VDC). Inzwane ineempawu zokulinganisa ezingahambelaniyo, kwaye inokuthintela ukunxiba ngoomatshini, kwaye ilungele imeko yokusebenza enobungozi efana nobushushu obuphezulu kunye nentshukumo.

Imeko yesicelo

I-1.High-uxinzelelo elawula uLawulo lweVolve

Kwiiyunithi ezinkulu ze-300MW kwaye ngaphezulu, i-Deh-LVDT-300-6 iyasebenzisana ne-Elecro-Hydraulic senves yokufikelela kulungelelwaniso lwe-± 0.1

I-2. Uxinzelelo lwe-Steam Steam Steam

Isetyenziselwa ukutshintshwa kohlobo lwe-Switch-teckiotors ukuqinisekisa i-valve echanekileyo / imiqondiso yendawo evaliweyo evulekileyo kwaye ikhusele i-turbine egqithisileyo okanye i-turbine egqithisileyo ngenxa yokuphambuka.

I-3. Amandla enyukliya kunye ne-petrochemicals

Lungelelanisa kwiinkqubo ze-oyile ezinganyangekiyo zomlilo, hlangabezane neemfuno zoqwalaselo ezingafunekiyo zeMigangatho ye-API ye-API670, kwaye ukuphelise umngcipheko wealamu zobuxoki ngeendlela ezahlukeneyo.

Ufakelo kunye nolondolozo

1. Ukufakwa koomatshini

-Ukunxaxha i-pidialty phakathi kwentsimbi kunye nentonga yokulinganisa kufuneka igcinwe kwi-¶0.1mm ukunqanda ukungathobeli.

-Sebenzisa i-M16 izibiyeli zentsimbi ezingenakwenzeka, kwaye imeko yokuqinisa isimo kufuneka ihlolwe rhoqo kwindawo eguqukayo.

I-2. Ukukhuthaza umbane

-Ukulinganisa isikhundla se-zero (ivalve evaliweyo) kunye nesikhundla esipheleleyo (ivalve ivulekile) ukuqinisekisa ukuba isiginali yokuphuma sihambelana nendawo yomzimba.

- Phantsi kocingo olufihliweyo kwelinye icala, kwaye umgama phakathi komgca womqondiso kunye nentambo yamandla yi-≥30cm ukuphinda iphazamise i-electromagnetic.

3. Ukubekwa kwendalo esingqongileyo

-Iingcingo ze-cerimic i-inshurensi kufuneka isetyenziswe kwiindawo ezinobushushu. Kucetyiswa ukuba ufake i-Shart Sink xa ubushushu bexesha elide bugqithile kwi-80 ℃.

I-hydraoke ye-hydraokeinzululwaziI-Deh-LVDT-300-6 iye yaba yinto ephambili yeenkqubo zokulawulwa kwe-turbine zale mihla kunye nemilinganiselo yayo engahambelaniyo, ichanekile kwaye inamandla okuphazamiseka. Ngokulondolozwa rhoqo kunye nokufakwa okufanayo, ukumiselwa kwemigaqo yeyunithizitha kunokuphuculwa ngokufanelekileyo kwaye umngcipheko wexesha elingacwangciswanga linokuncitshiswa.

Ngendlela, siye sabonelela ngamalungu okuhlala kwizityalo zamandla kwihlabathi liphela kangangeminyaka engama-20, kwaye sinamava otyebileyo kwaye sinethemba lokuba yinkonzo. Ndijonge phambili ukuva kuwe. Iinkcukacha zam zonxibelelwano zezi zilandelayo:
