Ziziphi iindlela zokukhusela emva kokugqithiswa kweivalvei actuator yombane?
Indlela yokunciphisa amafutha kwiivalvu
Okokuqala, ukucoca amanyathelo
Iinxalenye zevalvu kufuneka zihambe ngale nkqubo ilandelayo phambi kokudibanisa:
I-1, ngokweemfuno zokucubungula, ezinye iindawo zifuna ukwenza unyango lokupolisha, umphezulu awukwazi ukuba ne-process burr, njl.;
2. Onke amalungu athotyiwe;
I-3, i-pickling passivation emva kokunciphisa, i-arhente yokucoca ayinayo i-phosphorus ,;
I-4, emva kwe-pickling passivation, hlambulula ngamanzi acocekileyo, akukho ntsalela yeziyobisi, iinxalenye ze-carbon steel zishiya eli nyathelo;
5, enye nenxalenye enye ngelaphu non-elukiweyo owomileyo, ayikwazi ukugcina iinxalenye vulu ngocingo umphezulu, okanye nge nitrogen ecocekileyo owomileyo;
6. Sula iinxalenye nganye nganye ngelaphu elingalukwanga okanye iphepha lokucoca elichanekileyo elingcoliswe ngotywala obucocekileyo de kungabikho mbala umdaka.
Okwesibini, iimfuno zendibano
Iindawo ezicociweyo kufuneka zitywinwe ukuze kufakwe. Iimfuno zenkqubo yofakelo zezi zilandelayo:
1. Indawo yokusebenzela yokufakela mayicoceke, okanye imisele iindawo ezicocekileyo zethutyana, njengelaphu elinemibala esanda kuthengwa okanye ifilimu yeplastiki, ukuthintela uthuli ukuba lungangeni ngexesha lofakelo.
I-2, abasebenzi bendibano kufuneka banxibe iimpahla zomqhaphu ezicocekileyo zomsebenzi, banxibe ikepusi yomqhaphu esulungekileyo, iinwele azikwazi ukuvuza, iinyawo zinxibe izihlangu ezicocekileyo, izandla zinxibe iiglavu zeplastiki, zithomalalisa,.
3. Izixhobo zeNdibano kufuneka zicocwe kwaye zicocwe phambi kokudibanisa ukuqinisekisa ukucoceka
Ezinye iimfuno
1. Hlanza ivalve edibeneyo nge-nitrogen ubuncinane umzuzu o-1.
2, uvavanyo olungangeni moya kufuneka lube yinitrogen ecocekileyo.
3. Emva kokuphumelela uvavanyo lokungena moya, yipakishe kwaye uyitywine nge-cap ecocekileyo ye-polyethylene. Ngaphambi kokusebenzisa i-cap ye-polyethylene, yifake nge-solvent ephilayo kwaye uyisule.
4. Emva koko uyitywine ngengxowa yokufunxa.
5. Emva kokupakisha.
6. Kufuneka kuthathwe amanyathelo okuqinisekisa ukuba iphakheji ayonakaliswa ngexesha lokuthutha.
Iv. Iimfuno zokwamkelwa
Ukwamkelwa kuya kulandela i-HG 20202-2000 "Ikhowudi yoLwakhiwo kunye noKwamkelwa koBunjineli boKuhlisa igrisi". Phambi kokudibanisa, inxalenye nganye iyakusulwa ngephepha lokucoca elichanekileyo.
Zeziphi iindlela zokukhusela emva kokugcwala kakhulu kwevalvu yombane yombane?
Ivalve, njengemveliso ebalulekileyo yoomatshini abaxhasayo, ibandakanya yonke imiba yobomi babantu, kunye nemfuno eyandayo yentengiso yevalvu, ishishini lokwenziwa kweevalvu kwindawo enkulu yemfuno, ikwabonelela ngamathemba amahle kakhulu ophuhliso. Ke ngoko, ithuba eliphambi kwemarike yevalvu sele yenze ukhuseleko lomgangatho wemveliso kunye nokhuphiswano lophawu lwemveliso, ishishini ngalinye levalve likwiphulo lokusukela imveliso liya kuba liphezulu, iiparamitha eziphakamileyo, ukuxhathisa okuqinileyo, isikhokelo sobomi obuphezulu.
Ivalve yombane yombane sisixhobo esiyimfuneko ukuze siqonde ulawulo lwenkqubo yevalve, ulawulo oluzenzekelayo kunye nolawulo olukude. Inkqubo yayo yokunyakaza inokulawulwa ngokubetha, i-torque okanye i-axial thrust. Kwinkqubo yokuvelisa, i-motor ayisebenzisi umthwalo, le meko ayivumelekanga ukuba yenzeke. Ukuba kukho into enjalo, kuyimfuneko ukufumanisa isizathu, ngokubanzi kukhokelela kwizizathu ezilandelayo zomthwalo:
I-1, unikezelo lwamandla luphantsi, alukwazi ukufumana i-torque efunekayo, ukwenzela ukuba i-motor iyeke ukujikeleza;
I-2, ngokungalunganga ukusetha umda we-torque, ukuze ibe mkhulu kune-torque emisiwe, ekhokelela kwi-torque eqhubekayo, ukwenzela ukuba i-motor iyeke ukujikeleza;
I-3, ukusetyenziswa okwethutyana, ukonga ubushushu, ngaphezu kokunyuka kobushushu obuvumelekileyo bemoto;
4. Ngesizathu esithile, i-torque limiting mechanism circuit iyasilela kwaye i-torque inkulu kakhulu;
I-5, ukusetyenziswa kobushushu be-ambient kuphezulu kakhulu, xa kuthelekiswa nokunciphisa umthamo wobushushu bemoto.
Iindlela zokhuseleko ezisisiseko zokulayisha ngaphezulu:
I-1, i-motor eqhubekayo yokusebenza okanye i-point operation of overload protection, usebenzisa i-thermostat;
2, ukukhuselwa kwe-motor blocking, usebenzisa i-thermal relay;
3, kwingozi yesekethe emfutshane, sebenzisa i-fuse okanye i-overcurrent relay.
I-valve yombane ye-actuator sisixhobo esiyimfuneko ukuqonda ulawulo lwenkqubo yevalvu, ulawulo oluzenzekelayo kunye nolawulo olukude. Inkqubo yayo yokunyakaza inokulawulwa ngokubetha, i-torque okanye i-axial thrust. Ukukhetha okuchanekileyo kwesixhobo sombane sevalve kubaluleke kakhulu ukunqanda isenzeko sokugcwala (i-torque esebenzayo ephezulu kunetorque yolawulo). Ukumiselwa kweparameter engafanelekanga yenkqubo yokulawula kuya kubangela ukujikeleza kwenkqubo yokulawula. Ukuba inzuzo elinganayo ye-single loop regulator inkulu kakhulu, ixesha elidityanisiweyo lifutshane kakhulu, kwaye ixesha lokwahlula kunye nokuzuza okungafaniyo kukhulu kakhulu, kunokubangela ukuba inkqubo iqhube, kwaye ikhokelele kwi-actuator oscillation. Kwinkqubo yokulawula i-loop eninzi, ngaphezu kwezizathu ezingasentla, kukho kwakhona ingxaki yokusebenzisana phakathi kweelophu, ingxaki ye-resonance ebangelwa ukucwangciswa kweparameter engafanelekanga. Ngenxa yeengxaki ezikhoyo, iiparitha zinokutshintshwa kwakhona ukuze zenze i-loop yolawulo ibe nomda othile wokuzinza ngaphandle kokuchaphazela ukuveliswa kunye nokuhambelana neemfuno zokulawula inkqubo.
