I pipeline engineering, yero maber pa valve pa mac ubedo acel ikin piny ma pire tek mi tiyo ku piny ma mitere. Ka valve mi mac ma jutiyo kudu juyeru ngo maber, ebi nyayu peko ikum tic kende ngo, ento ebi kelo adwogi marac nyo rwinyo madit, pi meno, yero valve mi mac maber i yub pa pipeline engineering.
Kabedo mi tic pa valve pa mac
Mi medo ikum bedo moth ikum lembe ma mako pipeline, poyo wic ucikere ni bedu ikum kite ma tic pare utiye kudu, kum jam tic ma tiyo ku mac i valve pa mac utiye jam tic ma tiyo ku mac, man kite ma tic pare utiye ku aloka loka madit ikum kabedu ma tiyo kudu. Pol kare, kabedo mi tic pa valve pa mac utiye kudu:
1. Kethu piny i ot nyo tic woko ku yore mi gwoko kum;
2. Kethu piny woko i polo, ku yamu, lum, koth man ngico, lero pa ceng man nyai mange;
3. Etiye ku yamo ma wang nyo ma nyai nyo buru;
4. Kabedo ma ngic, ma ngic;
5. Lyethu pa pipeline ubedo malo ni 480°C nyo malu;
6. Liet pa piny utiye piny pa -20°C;
7. Eyot ni bedo i pii nyoke ni bedo i pii;
8. Kabedo ma tye ku piny ma nyayu lyethu (kabedo mi kero pa nuclear man jam pimo piny ma nyayu lyethu);
9. Kabedo mi yei nyo kabedo mi yei (ku kadu, lum, man pii);
10. Kare ku yeng yeng matek;
11. Kare ma mac copo wango;
Pi valve mi mac i kabedu ma juweco pigi malu, kit ma juyubu kudu, piny ma jutiyo kudu man yore mi gwoko jam tic pa mac ukoc. Pieno, jam tic ma rwate ku valve umaku juyer nimakere ku kabedu mi tic ma juweco pire malu.
Piny ma mitere pi tic pa macvalves
Nimakere ku cik mi tic pa engineering, pi valve pa mac, tic mi telowic uthum ku jam tic pa mac. Lembe ma pire tek mi tic ku valve mi mac utiye ni timo tic ku mac ma tiyu ngo ku cing nyo kompyuta pi yabo, cego man loko valve. Jam tic ma tiyo ku mac ma kawoni jutiyo kudu pi gwoko dhanu kende ngo. Ni lembe matung tung matung tung ikind tic man ber pa piny ma juyubu kud i bang juyiku piny matung tung, yero jam tic ma tiyo ku mac man yero valves piretek marom ni yub eni.
Gwoko mac pa macvalves
Ni kadhu kud i dongo pa piny ma mitere pi tic ku cuma, yo acel, tic ku valve mi mac ube medere, man yo mukende, yeny pa valve mi mac ube medere man tek. Pieno, kit ma juyubu ku valve mi mac i yore mi gwoko mac de judwoko manyen kare ku kare. Ku dongo pa ngec man diro man dongo pa kompyuta, yore manyen man matung tung mi tic ku mac bimediri ni wok. Pi telo wi tic pa macvalve, jubiketho cwiny ikum yero kit mi telo wi valve pa mac. Ku lapor, nimakere ku yeny pa tic, kadi tiyo ku centralized control mode, nyo single control mode, kadi tiyo ku jam tic mange, program control nyo tic ku program mi kompyuta, man mange, cik mi control utiye tung tung. Lanyuth pa ju ma yiku jam tic mi mac mi valve kende re ma mio cik mi gwoko mac, ci dipatmen mi tic ucikere ni timo lembe ma jukoro ku ju ma yiku jam tic mi mac man ni nyuthu lembe ma mitere. Mi medo, ka ibe yero valve pa mac, umitu ipar ka ibe wilu valve pa mac mukende. Pien i rwom ma malu, controller umitu juwil kende kende. Pol kare, ka itiyo ku jam tic acel, ber ni wilu jam tic, kum etiye yot man yot ni wilu jam tic ma sagu yubu man yubu ku jatic. Ka tic pa mac copo rombu ngo ku yeny mi yiku piny, ju ma yiku piny ucikere ni kwayu ni loko nyo ni yubu kendu.
Jam tic ma tiyo ku mac pa valve ubedo jam tic ma timo program pa valve, timo tic kende kende man timo tic ku remote*, man timo pare copo bedu ku rwom pa stroke, torque nyo axial thrust. Calu tic pa valve actuator ucungo iwi kit valve, tic pa jam tic, man kabedo pa valve iwi pipeline nyoke jam tic, yero maber pa valve actuator piretek pi jwigo tic ma lee (torque mi tic utiye malo uloyu torque mi tela). I ayi ma rwinyo, the lembe ma pire tek pi yero jam tic ma tiyo ku valve electric utiye ma e:
Teko mi ticTorque mi tic ubedo piny ma pire tek pi yero jam tic mi mac pa valve, man torque ma wok kud i jam tic mi mac ucikere ni bedu 1.2~1.5 pa torque mi tic pa valve.
Tye kit cuma ario madongo ma tiyo ku thrust valve electric device: acel epe ku thrust disc man ewodho torque direct; Mukende utiye mi ketho thrust plate, man torque ma wok kud i iye lokore ni output thrust nikadhu kud i stem nut i thrust plate.
Wel mi loko pa dul ma wok kud i valve electric device utiye ku winjiri ku diameter pa valve, pitch pa stem man wel pa threads, ma umitu jukwan nimakere ku M=H/ZS (M utiye wel mi rotations ma jam tic mi mac umaku etim, H utiye bor pa valve, S utiye pitch pa thread pa valve, Z utiye namba pa threads kuvalvekor tyend).
Ka dit pa stem diameter ma juyiyu ku jam tic mi mac copo kadhu kud i stem pa valve ma juketho, ecopu ngo ni ketho i valve pa mac. Pieno, diameter ma iye pa hollow output shaft pa actuator umaku obed malac uloyu diameter ma woko pa stem pa open rod valve. Pi dark rod valve in partial rotary valve man multi-turn valve, kadi nya peko mi kadho pa valve stem diameter epe, diameter pa valve stem man dit pa keyway de umaku juketh i iye kare ma juyero, kara etim tic maber ingey ketho.
Ka ngwec mi yabo man mi cego pa valve mi ngwec mi wok ubedo tek akeca, ebedo yot ni yubu water hammer. Pieno, rwom maber mi yabo man mi cego umaku juyer nimakere ku kit tic matung tung.
Valve actuators utiye ku yeny migi ma pire tek, niwacu umitu gibed ku copo mi nyutho torque nyo axial forces. Njavalveactuators tiyo ku torque-limiting couplings. Ka dit pa jam tic ma tiyo ku mac ungiyu, kero pare de ungiyu. Pol kare tiyo i sawa ma juyike, mutukari bibedo ku tic madwong ungo. Ento, ka lembe ma e utimiri, ecopu telu rwom ma malu: mir acel, voltage pa mac utiye piny, man torque ma mitere ecopu nwangu ngo, ma weko motor juku ngwec; mir aryo utiye ni loko yore mi jwigo torque kara ebed malac uloyu torque mi juku, ma kelo torque madwong man juku mutukari; mir adek utiye tic ma rwinyo, man lyethu ma juyubu ukadhu rwom pa lyethu ma juyiko pa mutukari; Mir angwen, circuit pa torque limiting mechanism upodhu pi the lembe moku, ma weko torque doko dit akeca; Mir abic, lyethu pa piny ubedo malo akeca, ma dwoko piny kero pa lyethu pa mutukari.
I kare mukadho, yore mi gwoko mutukari ubedu nitio ku fius, overcurrent relays, thermal relays, thermostats, man mange, ento yore eni gitiye ku bero man rac migi. Yore moko mbe mi gwoko piny ma pek migi lokore calu jam tic ma tiyo ku mac. Pieno, umitu jutim lembe matung tung, ma jucopo poko i dul aryo: acel utiye mi ngiyo medo nyo dwoko piny pa kero pa mutukari; Mir aryo utiye ni ngolo lembe ikum lyethu pa mutukari kende. I yore moku ci, yore moku ci tero i iye kare ma jumiyo pi kero pa lyethu pa mutukari.
Pol kare, yore ma pire tek mi gwoko piny ma tek utiye: gwoko piny ma tek pi tic ma mediri nyo tic ma rwinyo pa mutukari, nitio ku thermostat; Pi gwoko motor stall rotor, thermal relay jutiyo kudu; Pi ret ma nyai, fuse nyo overcurrent relays jutiyu kudu.
