Uvavanyo kunye nendlela yokwamkelwa yobushushu obuphezulu bempompo yeoli eshushu ye-centrifugal Ufakelo oluneenkcukacha kunye nendlela yohlengahlengiso lwempompo yeoli ye-slag kunye nevalve
Emva kokulungiswa, ipompo ye-oyile eshushu ye-centrifugal kufuneka ihlolwe ukujonga ukuba kukho iingxaki kuzo zonke iindawo zempompo, ngokukodwa ukujonga ukuba amandla okusebenza kompompo ahlangabezana neemfuno. Ukuba iingxaki zifunyenwe ngexesha lovavanyo, zinokusingathwa kwangethuba ngaphambi kokuba zisetyenziswe. Ngenxa yokuba umpompo emva kokulungiswa, kufuneka siqinisekise umgangatho, ukwenzela ukuba ipompo ibe kwimeko yokusebenza kakuhle, ukusebenza ngokukhuselekileyo kwi-overhall elandelayo. Umgangatho wokugcinwa uhlangabezana neemfuno, irekhodi yokulondoloza iphelele kwaye ichanekile, ukuhlolwa kovavanyo kuqhelekileyo, kwaye iinkqubo zokwamkelwa zingaphathwa ngokuhambelana nezibonelelo kwaye zihanjiswe ukuze zisetyenziswe.
1. Injongo yovavanyo lwempompo yeoli eshushu ye-centrifugal
Emva kokulungiswa, ipompo ye-oyile eshushu ye-centrifugal kufuneka ihlolwe ukujonga ukuba kukho iingxaki kuzo zonke iindawo zempompo, ngokukodwa ukujonga ukuba amandla okusebenza kompompo ahlangabezana neemfuno. Ukuba iingxaki zifunyenwe ngexesha lovavanyo, zinokusingathwa kwangethuba ngaphambi kokuba zisetyenziswe. Ngenxa yokuba umpompo emva kokulungiswa, kufuneka siqinisekise umgangatho, ukwenzela ukuba ipompo ibe kwimeko yokusebenza kakuhle, ukusebenza ngokukhuselekileyo kwi-overhall elandelayo.
2. Iimfuno zovavanyo lwempompo yeoli eshushu ye-centrifugal
(1) Izinto kufuneka zitshekishwe phambi kokuba kuqhutywe uvavanyo:
1) Khangela ukuba umgangatho uyahlangabezana neemfuno kunye nokuba irekhodi lokugcinwa liphelele kwaye lichanekile.
2) Ingaba inkqubo yeoli yokuthambisa ayivalwanga kwaye ayivuzi.
3) Ingaba ukuvuza kwetywina le-shaft kuyahlangabezana neemfuno.
4) nokuba akukho mvakalelo yokungalingani kwesisindo, ukupakisha i-gland ayiguquki.
(2) Umthwalo uya kuhlangabezana nezi mfuno zilandelayo
I-1) Emva kokuqala amandla okwenza ipompo iqhube kwisantya esilinganiselweyo, khangela ukuba kukho ingxolo, ukuguquka, ukungcangcazela okunobundlobongela okanye ukuvuza kunye nezinye iimeko ezimbi kwindawo nganye. I-amplitude kwi-shaft yempompo ayiyi kudlula leyo ichazwe kwiThebhile 3-36.
I-2) Ngaphantsi kwentloko elinganisiweyo, ukufuduka akuyi kuba phezulu okanye ngaphantsi kwe-5% yokukhutshwa okulinganiselweyo.
Pump shaft amplitude umgangatho
3) Ngaphakathi koluhlu lokufuduka oluchazwe ngasentla, intloko epheleleyo yevalve yepompo yePoitou Taibang ayiyi kuba ngaphantsi kwentloko elinganisiweyo.
4) Umsinga awuyi kudlula umbane olinganisiweyo kwi-rated displacement, intloko iyonke kunye ne-voltage elinganisiweyo.
I-5) iqondo lokushisa elijikelezayo alikho ngaphezu kwe-65 ° C, kwaye iqondo lokushisa elijikelezayo alikho ngaphezu kwe-70 ° C.
6) Ukuvuza kwetywina akusayi kudlula ezi mfuno zilandelayo:
Isitywina somatshini: ioli ekhanyayo i-10 yehla / min, ioli enzima i-5 yehla / min.
② Isitywina sokupakisha esithambileyo: ioli elula i-20 yehla / min, ioli enzima i-10 yehla / min.
3. Iimfuno zokwamkelwa kweempompo zeoli ezishushu ze-centrifugal
Umgangatho wokugcinwa uhlangabezana neemfuno, irekhodi yokulondoloza iphelele kwaye ichanekile, ukuhlolwa kovavanyo kuqhelekileyo, kwaye iinkqubo zokwamkelwa zingaphathwa ngokuhambelana nezibonelelo kwaye zihanjiswe ukuze zisetyenziswe.
Ufakelo kunye nendlela yokulungelelanisa ipompo ye-oyile ye-slag ephezulu kunye ne-valve
Ukutywinwa okusebenzayo kwempompo ye-slag yoxinzelelo oluphezulu kunye ne-valve kuxhomekeke kwimeko yonke yamacandelo ngamanye. Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwisiqinisekiso sokuba izixhobo ezifuna ukutshintshwa kwengcambu ye-pan ziye zahlulwa ngokufanelekileyo ngokuhambelana nesayithi kunye nenkqubo ngaphambi kokufakwa kwengcambu ye-pan. Oku kulandelayo kusetyenziselwa ukukhokela abasebenzi bolondolozo, iinjineli, kunye nabahlanganisi ukufaka ngokufanelekileyo kunye nokulungelelanisa ingcambu ye-pan.
1. Izixhobo ezifunekayo kufuneka zisetyenziswe ukususa ingcambu ye-pan endala kunye nokubuyisela ingcambu entsha ye-pan kunye ne-** izixhobo, impompo ye-oyile ye-slag yoxinzelelo oluphezulu kunye nokuqinisa i-nut ye-gland nge-fastener. Ukongezelela, ukusetyenziswa rhoqo kweendawo zokhuseleko ezisemgangathweni kunye nokuthotyelwa kwemigaqo yokhuseleko efanelekileyo kuyadingeka. Ngaphambi kofakelo, ziqhelanise nezi zixhobo zilandelayo: umatshini wokusika ukukhangela i-disk root ring, khangela i-torque wrench okanye i-wrench, umnqwazi oqinileyo, i-caliper yangaphakathi nangaphandle, i-lubricant yesixhobo sokuqinisa, isibonisi, i-pan root extractor, isixhobo sokusika ingcambu, i-vernier calipers. , njl
2. Ukucoca kunye nokuhlolwa
I-1) Kancinci ukhulule i-nut ye-gland yebhokisi yokuhlohla ukukhulula lonke uxinzelelo olushiyekileyo kwindibano yeengcambu ze-pan;
2) Susa naziphi na iingcambu ezidala kwaye uhlambulule ngokucokisekileyo ibhokisi yokufaka i-shaft / intonga;
3) Khangela ukuba i-shaft / intonga ine-corrosion, i-dents, i-scratches okanye ukuguga ngokugqithiseleyo;
4) Khangela ukuba ezinye iindawo zine-burrs, ii-cracks, i-wear, ziya kunciphisa ubomi beengcambu;
5) Khangela ukuba ibhokisi yokuhlohla inokukhutshwa okukhulu kakhulu, kunye ne-shaft / intonga eccentricity;
6) Faka iindawo ezineziphene ezinkulu;
7) Khangela ingcambu endala njengesiseko sokuhlalutya ukungaphumeleli ukufumana isizathu sokungaphumeleli kwangaphambili kwengcambu.
3. Ukulinganisa kwaye urekhode ububanzi be-shaft / intonga, indawo yokuvula kunye nobunzulu bebhokisi yokugxusha, kunye nomgama ukusuka ezantsi ukuya phezulu kwibhokisi yokupakisha urekhodwa xa umsesane uvalwe ngamanzi.
4, khetha ingcambu
1) Qinisekisa ukuba i-pan ekhethiweyo kufuneka ihlangabezane neemeko zokusebenza ezifunwa yinkqubo kunye nezixhobo;
2) Ngokweerekhodi zokulinganisa, bala indawo enqamlezileyo yengcambu kunye nenani lamakhonkco eengcambu ezifunekayo;
3) Khangela ingcambu ukuze uqinisekise ukuba akukho ziphene;
4) Ngaphambi kokufaka, qinisekisa ukuba izixhobo kunye neengcambu zicocekile.
I-5, ukulungiswa kwendandatho yeengcambu
1) Braid iingcambu ngokujija iingcambu kwi-shaft yobungakanani obufanelekileyo, okanye usebenzisa i-calibrated root ring cutter; Ngokucocekileyo SIKA IIMPANDU ZEDISCI UBE EBUTT (ISIkwere) OKANYE UMITA (30-45 DIGREES) NJENGOKO KUFUNEKA, I-RING ENYE NGEXESHA, UZE UJONGE UBUKHULU OBUNE-SHAFT OKANYE ISIQINISO.
2) Iidiski ezibunjiweyo ziqinisekisa ukuba ubungakanani bomsesane buhambelana ngqo ne-shaft okanye isiqu. Ukuba kuyimfuneko, sika amakhonkco okupakisha ngokwemiyalelo yokusebenza yomenzi okanye iimfuno.
6, ukufakwa kwengcambu yediski ngokucokisekileyo faka ikhonkco enye ngexesha, ikhonkco ngalinye lijikeleze i-shaft okanye isiqu, ngaphambi kokufaka i-ring elandelayo, kufuneka uqiniseke ukuba i-** ring ibe yindawo ngokupheleleyo kwibhokisi yokuhlohla, elandelayo. umsesane kufuneka ulungelelanise ilungiselelo, ubuncinane 90 degrees ngaphandle, imfuneko jikelele 120 degrees. Emva kokuba i-ring yokugqibela ifakwe, qinisa i-nut ye-high-pressure slag oil pump ngesandla, kwaye ucinezele i-gland ngokulinganayo. Ukuba kukho umsesane wokutywina wamanzi, kufuneka kuhlolwe ukuba umgama ovela phezulu kwibhokisi yokufaka ulungile. Kwakhona qinisekisa ukuba i-shaft okanye isiqu sinokujikeleza ngokukhululekileyo.
7. Lungisa i-pan ingcambu yempompo yeoli ye-slag ephezulu yoxinzelelo
1) impompo enengcambu ye-pan
(1) Qhubeka uqinisa i-nut nut ngesandla;
(2) Emva kokuvula impompo, lungisa i-nut yedlala ukuvumela ukuvuza okungakumbi;
(3) Kancinci uqinise i-nut ye-gland ukunciphisa kancinci ukuvuza de ukuvuza kufikelele kwinqanaba elamkelekileyo;
4
(5) Lungisa umlinganiselo wokuvuza ukuze ufikelele kwisimo esizinzileyo.
2) Qhagamshelana nomenzi wekhoyili okanye isebe lobuchwephesha beshishini malunga nemigaqo yetorque okanye ipesenti yoxinzelelo lwevalve enengcambu yekhoyili, kwaye uqinise i-nut yedlala ngolu hlobo lulandelayo:
(1) Faka itorque kwi-gland nut ukuya kuma-30% etorque epheleleyo okanye ipesenti yoxinzelelo lweqela;
(2) vula ngokuphindaphindiweyo kwaye uvale ivalve amaxesha amaninzi, xa ivalve ikwindawo evaliweyo, sebenzisa yonke i-torque;
(3) Phinda inyathelo (2)3 okanye 4 amaxesha.
8. Qinisa kwaye ubuyisele kwakhona emva kweeyure eziliqela zokusebenza, jonga isimo sokulungelelaniswa kwe-gland yepompo ye-oyile ye-slag ephezulu yoxinzelelo, qinisa xa kuyimfuneko, kwaye ubeke indawo yengcambu ye-pan xa i-gland ingakwazi ukulungiswa ngakumbi.
