Isiqulatho
4. Isikhokelo sokukhetha ivili lesandla seemeko ezahlukeneyo
5. Iskimu sokuphucula ubungakanani ngokwembono ye-ergonomics
6. Uhlalutyo lweengozi zamashishini ezibangelwa ubungakanani obungafanelekanga
Kwintsimi yeenkqubo zemibhobho yoshishino, iivalve zebhola ze-manual zizinto eziphambili zokulawula, kunye noyilo lwezixhobo zabo zokusebenza luchaphazela ngokuthe ngqo ukusebenza kwenkqubo. Ngokwengxelo yonyaka ka-2024 yoMbutho woShishino lweValve yaseChina, ukuthunyelwa ngonyaka kweevalvu zezandla kwilizwe lam kudlule i-23 yezigidi zeeyunithi, apho iivalvu zebhola ezixhotyiswe ngamavili ezandla aqhelekileyo zibalelwa kwi-62%. Ngokukhawuleza kwenkqubo ye-Industry 4.0, uyilo lobuntu lwe-interface yokusebenza lube luphawu olubalulekileyo lokuphucula izixhobo.
Idatha yokuhlola ishishini ibonisa:
I-1.45% yeengozi zokusebenza kwisayithi zinxulumene neziphene zoyilo lwamavili
2. Ukuphucula ubungakanani bevili lesandla kunokunyusa ukusebenza kakuhle nge-18%
3. Yonke i-1N·m yokunciphisa i-torque yokusebenza inokunciphisa izehlo zonyaka zomsebenzi{2}}zokwenzakala okunxulumene ne-3.2%
2. Ubudlelwane bomatshini phakathi kobukhulu bevili lesandla kunye nokuvula nokuvala ukusebenza kakuhle
● Ukusekwa kwemodeli yoomatshini
Ubudlelwane phakathi kwedayamitha yevili lesandla (D) kunye netorque yokusebenza (T) ilandela umgaqo weleva:
T = F × D/2
Apho u-F angamandla okusebenza kunye no-D yidayamitha yevili lesandla. Xa i-torque yokuvula kunye nokuvala efunekayo yokutywinwa kwevalve ilungisiwe, ukwandisa i-handwheel ye-handwheel inokunciphisa kakhulu imfuneko yamandla okusebenza.
● Imiba echaphazela isantya
I-1.I-Diameter threshold effect: Iimvavanyo zibonisa (bona [3] idatha yevalve yesango ngeenkcukacha) ukuba xa i-handwheel ye-diameter idlula i-400mm, ixesha lokusebenza landa nge-5-8% ngenxa yokwanda kwe-inertial ejikelezayo ebangelwa ubungakanani obukhulu.
2.I-Friction coefficient variable: Xa kuthelekiswa nezinto ezidityanisiweyo zenayiloni (μ{1}}), isantya sokuvula nokuvala ivili lesandla sentsimbi etyhidiweyo (μ{2}}) icuthwe ngama-22% kwidayamitha efanayo.
I-3.I-Transmission ratio optimization: Uyilo lwe-1:50 yokunciphisa umlinganiselo wesakhiwo segiya ye-worm inokunyusa isantya sokusebenza sevili lesandla eliqhelekileyo (Φ300mm) ngamaxesha angama-3
Idatha yovavanyo: Uphononongo kubungakanani-ulungelelwaniso lwesantya se-DN500 ivelufa yebhola
Ivalve yebhola ye-DN500 esetyenziswe kwiprojekthi yepetrochemical isetyenziswe njengesampulu (jonga idatha yofakelo kwi- [4]) ukuvavanya ukusebenza kokuvula nokuvalwa kobukhulu obuhlukeneyo besandla:
| Idayamitha yesondo lesandla (mm) | Ixesha lilonke lokuhamba (a) | Awona mandla okusebenza aphezulu (N) | Inani lokujikeleza |
| 300 | 48.2 | 180 | 12 |
| 400 | 35.6 | 135 | 12 |
| 500 | 42.1 | 108 | 12 |
| 600 | 53.8 | 90 | 12 |
Iziphumo eziphambili:
I-400mm ye-diameter ifezekisa i-peak yesantya, iqinisekisa i-dameter threshold effect
Kuwo onke ukwanda kwe-100mm ububanzi, amandla okusebenza ayancipha malunga ne-25%
Iqela le-600mm linokubola kwesantya ngenxa ye-inertia egqithisileyo
4. Isikhokelo sokukhetha ivili lesandla seemeko ezahlukeneyo
● Imatrix yokukhetha iimeko eziqhelekileyo zokusebenza
| Uxinzelelo lwemibhobho (MPa) | Ubushushu obuphakathi ( isidanga ) | Idayamitha ecetyiswayo (mm) | Iinketho zezinto eziphathekayo |
| Ngaphantsi okanye ilingana no-1.6 | -20~120 | 300-350 | Yenza i-aluminiyam/intsimbi eyomeleziweyo |
| 2.5-4.0 | 121-300 | 400-450 | Intsimbi yentsimbi |
| Inkulu kuno okanye ilingana no 6.4 | >300 | 500+ | Intsimbi engatyiwa 304/316 |
● Izisombululo ezikhethekileyo zokuqhelaniswa nokusingqongileyo
1. Isithuba esivalekileyo: ivili lesandla elisongelwayo (idayamitha evuliweyo 400mm/idayamitha esongiweyo eyi-220mm)
2
3. Iimeko zobushushu obuphantsi: kabini-umaleko onomngxuma wokunqanda ukukhenkceka kwevili lesandla
5. Iskimu sokuphucula ubungakanani ngokwembono ye-ergonomics
●Iqela lophando leSebe lobuNjineli booMatshini leDyunivesithi yaseTsinghua licebise ngethiyori ethi "Golden Ratio":
1.Idiyamitha yevili lesandla elilungileyo=ububanzi besandla somsebenzisi × 3.14.
2.I-avareji yobubanzi besundu samadoda amadala ase-China yi- 86mm → i-diameter ecetyiswayo yi-270mm, ehambelana kakhulu ne-300mm yeendawo eziqhelekileyo kubunjineli bokwenene.
●Uvavanyo lobuchwephesha babantu lubonisa ukuba:
1.Xa i-diameter ingaphantsi kwe-250mm, uxinzelelo kumalungu omnwe ludlula i-18kPa.
2.Xa ububanzi bukhulu kune-450mm, uluhlu lwamagxa eemfuno zentshukumo lukhula nge-40%.
6. Uhlalutyo lweengozi zamashishini ezibangelwa ubungakanani obungafanelekanga
