Yiziphi izindlela zokuvikela ngemuva kokugcwala kwe-i-valvei-actuator kagesi?

Indlela yokunciphisa ama-valve
Okokuqala, ukuhlanza izinyathelo
Izingxenye ze-valve kufanele zidlule kunqubo elandelayo ngaphambi kokuhlanganisa:
1, ngokwezidingo zokucubungula, ezinye izingxenye zidinga ukwenza ukwelashwa kokupholisha, indawo engaphezulu ayikwazi ukucubungula i-burr, njll.;
2. Zonke izingxenye zehlisiwe;
3, pickling passivation ngemva degreasing, yokuhlanza ejenti ayinayo phosphorus,;
4, ngemva pickling passivation, hashaza ngamanzi ahlanzekile, akukho izinsalela izidakamizwa, carbon steel izingxenye yeka lesi sinyathelo;
5, ingxenye ngayinye ngendwangu engeyona eyelukiweyo eyomile, ayikwazi ukugcina izingxenye zoboya zocingo, noma nge-nitrogen ehlanzekile eyomile;
6. Sula izingxenye ngayinye ngayinye ngendwangu engalukiwe noma iphepha lokuhlunga elinemba elinotshwala obumsulwa kuze kungabi bikho umbala ongcolile.
Okwesibili, izidingo zomhlangano
Izingxenye ezihlanziwe kufanele zivalwe ukuze zifakwe. Izidingo zenqubo yokufaka zimi kanje:
1. Indawo yokusebenzela yokufaka kufanele ihlanzeke, noma imise izindawo ezihlanzekile zesikhashana, njengendwangu enemibala esanda kuthengwa noma ifilimu yepulasitiki, ukuvimbela uthuli ukuthi lungangeni ngesikhathi sokufakwa.
I-2, izisebenzi zomhlangano kumele zigqoke izingubo zokusebenza zikakotini ezihlanzekile, zigqoke isigqoko sikakotini esihlanzekile, izinwele azikwazi ukuvuza, izinyawo zigqoke izicathulo ezihlanzekile, izandla zigqoke amagilavu ​​epulasitiki, ukugcoba,.
3. Amathuluzi omhlangano kufanele asuswe amafutha futhi ahlanzwe ngaphambi kokuhlanganiswa ukuze kuqinisekiswe ukuhlanzeka
Ezinye izidingo
1. Hlanza i-valve ehlanganisiwe nge-nitrogen okungenani iminithi elingu-1.
2, ukuhlolwa okungangenisi umoya kumele kube yi-nitrogen emsulwa.
3. Ngemva kokuphumelela ukuhlolwa okungangenisi umoya, yipakishe futhi uyivale ngekepisi elihlanzekile le-polyethylene. Ngaphambi kokusebenzisa ikepisi le-polyethylene, cwilisa nge-solvent ephilayo bese usula ihlanzekile.
4. Bese uyivala ngesikhwama sevacuum.
5. Ngemva kokupakisha.
6. Kufanele kuthathwe izinyathelo zokuqinisekisa ukuthi iphakethe alilimazi ngesikhathi sokuthutha.
Iv. Izidingo zokwamukela
Ukwamukelwa kuzolandela i-HG 20202-2000 “Ikhodi Yokwakha Nokwemukelwa Kobunjiniyela Bokwehlisa Igrease”. Ngaphambi kokuhlanganisa, ingxenye ngayinye izosulwa ngephepha lokuhlunga elinemba elihlanzekile.
Yiziphi izindlela zokuvikela ngemuva kokugcwala ngokweqile kwe-valve actuator kagesi?
I-Valve, njengemikhiqizo yemishini ebalulekile esekelayo, ibandakanya zonke izici zokuphila kwabantu, nesidingo esandayo semakethe yama-valve, imboni yokukhiqiza ama-valve endaweni enkulu yokufunwa, ibuye iveze amathemba amahle kakhulu entuthuko. Ngakho-ke, ithuba eliphambi kwemakethe yama-valve selicishe lakha ukuncintisana kokuphepha kwekhwalithi yomkhiqizo kanye nokuncintisana komkhiqizo, ibhizinisi ngalinye le-valve liphishekela umkhiqizo lizoba ngobuchwepheshe obuphezulu, imingcele ephezulu, ukumelana nokugqwala okuqinile, isiqondiso sempilo ephezulu.
I-valve actuator kagesi iyisisetshenziswa esibalulekile sokubona isilawuli sohlelo lwe-valve, isilawuli esizenzakalelayo nesilawuli kude. Inqubo yayo yokunyakaza ingalawulwa nge-stroke, i-torque noma i-axial thrust. Enqubweni yokukhiqiza, injini ayisetshenziswanga umthwalo, lesi simo asivunyelwe ukwenzeka. Uma kukhona isenzakalo esinjalo, kubalulekile ukuthola imbangela, ngokuvamile kuholela izizathu ezilandelayo umthwalo:
1, amandla aphansi aphansi, awakwazi ukuthola i-torque edingekayo, ukuze injini iyeke ukujikeleza;
2, ukusetha ngokungalungile indlela yomkhawulo we-torque, ukuze ibe mkhulu kune-torque emisiwe, okuholela ku-torque eqhubekayo, ukuze injini iyeke ukujikeleza;
3, ukusetshenziswa ngezikhathi ezithile, ukonga ukushisa, ngaphezu kokushisa okuvumelekile kwemoto;
4. Ngesizathu esithile, umjikelezo we-torque wokukhawulela i-torque uyahluleka futhi i-torque inkulu kakhulu;
I-5, ukusetshenziswa kokushisa kwe-ambient kuphezulu kakhulu, uma kuqhathaniswa nokunciphisa umthamo wokushisa we-motor.
Izindlela zokuvikela eziyisisekelo zokulayisha ngokweqile:
1, ukusebenza okuqhubekayo kwe-motor noma ukusebenza kwephoyinti lokuvikela ukugcwala ngokweqile, kusetshenziswa i-thermostat;
2, ukuvikelwa motor blocking, usebenzisa edluliselwe ezishisayo;
3, ngengozi yesifunda esifushane, sebenzisa i-fuse noma i-overcurrent relay.
I-Valve electric actuator iyisisetshenziswa esibalulekile sokulawula uhlelo lwe-valve, isilawuli esizenzakalelayo nesilawuli kude. Inqubo yayo yokunyakaza ingalawulwa nge-stroke, i-torque noma i-axial thrust. Ukukhetha okulungile kwedivayisi kagesi ye-valve kubaluleke kakhulu ukuvimbela into egcwala kakhulu (i-torque esebenzayo iphakeme kune-torque yokulawula). Ukusetha okungalungile kwepharamitha yesistimu yokulawula kuzodala ukuzulazula kwesistimu yokulawula. Uma inzuzo elinganiselwe yesilawuli se-loop eyodwa inkulu kakhulu, isikhathi esihlanganisiwe sifushane kakhulu, futhi isikhathi sokuhlukanisa kanye nokuzuza okuhlukile kukhulu kakhulu, kungase kubangele isistimu ukuthi i-oscillate, futhi iholele ku-oscillation ye-actuator. Ngohlelo lokulawula i-loop eningi, ngaphezu kwezizathu ezingenhla, kuphinde kube nenkinga yokusebenzisana phakathi kwezihibe, inkinga ye-resonance ebangelwa ukulungiselelwa kwepharamitha okungalungile. Ngenxa yezinkinga ezikhona, imingcele ingashintshwa kabusha ukuze wenze i-loop yokulawula ibe nomkhawulo othile wokuzinza ngaphandle kokuthinta ukukhiqiza futhi ngokuhambisana nezidingo zokulawula inqubo.
