Tafura yezviri mukati
2. Mechanical ukama pakati handwheel size uye kuvhura uye kuvhara kushanda zvakanaka
4. Handwheel yekusarudza gwara kune akasiyana mamiriro
5. Size optimization scheme kubva pakuona kweergonomics
6. Kuongororwa kwezviitiko zvemaindasitiri zvinokonzerwa nekukura kusina kunaka
Mumunda wemaindasitiri pombi masisitimu, mavharuvhu ebhora ndiwo akakosha ekudzora zvikamu, uye magadzirirwo emidziyo yavo yekushandisa anokanganisa zvakananga mashandiro ehurongwa. Sekureva kwe2024 mushumo wepagore weChina Valve Indasitiri Association, kutumirwa kwepagore kwemavharuvhu emaoko munyika yangu kwakapfuura mamirioni makumi maviri nematatu, ayo mavharuvhu ebhora akashongedzerwa mavhiri emaoko akaenzana ne62%. Nekuwedzera kwemaitiro eIndasitiri 4.0, dhizaini yemunhu yeanoshanda interface yave chiratidzo chakakosha chekusimudzira michina.
Indasitiri yekutarisa data inoratidza:
1.45% yetsaona dzepa-saiti ine chekuita nekukanganisika kwekugadzirwa kwevhiri remaoko
2. Kugadzirisa saizi yegumbo remaoko kunogona kuwedzera kushanda zvakanaka ne18%
3. Kudzikiswa kwe1N·m kwega kwega kwetorque yekushanda kunogona kuderedza kuitika kwepagore kwekukuvara kwebasa-kune 3.2%
2. Mechanical ukama pakati handwheel size uye kuvhura uye kuvhara kushanda zvakanaka
● Kugadzwa kwema mechanical model
Hukama huri pakati pehandwheel dhayamita (D) uye torque yekushandisa (T) inoteera musimboti welever:
T = F × D/2
Ipo F isimba rinoshanda uye D ndiro dhayamita yevhiri remaoko. Kana iyo yekuvhura uye yekuvhara torque inodiwa kuvharika chisimbiso yakagadziriswa, kuwedzera handwheel dhayamita inogona kuderedza zvakanyanya simba rekushanda rinodiwa.
● Speed kupesvedzera zvinhu
1.Diameter threshold effect: Miedzo inoratidza (ona [3] data yevhavha yegedhi yemashoko) kuti kana dhayamita yegumbo remaoko rinopfuura 400mm, nguva yekushanda inowedzera ne5-8% nekuda kwekuwedzera kwekutenderera inertia kunokonzerwa nehukuru hukuru.
2.Friction coefficient variable: Kana ichienzaniswa nenylon composite material (μ=0.12), kuvhura nekuvharika kwevhiri reruoko resimbi yakakandwa (μ=0.25) inodzikiswa ne22% padhayamita imwe chete.
3.Transmission ratio optimization: Iyo 1:50 yekudzikisa reshiyo dhizaini yeworm gear chimiro inogona kuwedzera kumhanya kwekushanda kweiyo yakajairika handwheel (Φ300mm) ne3 nguva.
Data yekuedza: Kudzidza pakukura-kuspeed correlation yeDN500 ball valve
DN500 bhora vharafu rinoshandiswa petrochemical purojekiti yakashandiswa semuenzaniso (tarisa kune yekumisikidza data mu [4]) kuyedza kuvhura nekuvhara kushanda kweakasiyana mavhiri emaoko:
| Dhiyamita yevhiri reruoko (mm) | Nguva yese yekufamba (s) | Simba guru rekushanda (N) | Nhamba yekutenderera |
| 300 | 48.2 | 180 | 12 |
| 400 | 35.6 | 135 | 12 |
| 500 | 42.1 | 108 | 12 |
| 600 | 53.8 | 90 | 12 |
Zvakawanikwa zvakakosha:
Iyo 400mm dhayamita inowana iyo yekumhanyisa peak, ichisimbisa iyo dhayamita pachikumbaridzo maitiro
Kune yega yega 100mm kuwedzera kwedhayamita, simba rekushandisa rinoderera ne25%
Iro boka re600mm rine kukurumidza kuora nekuda kwekunyanyisa inertia
4. Handwheel yekusarudza gwara kune akasiyana mamiriro
●Sarudzo matrix yemamiriro ekushanda akajairika
| Pipeline pressure (MPa) | Tembiricha yepakati (degree) | Inokurudzirwa dhayamita (mm) | Zvinhu zvingasarudzwa |
| Zvishoma pane kana kuenzana ne1.6 | -20~120 | 300-350 | Kanda aluminium / yakasimbiswa simbi yakakandwa |
| 2.5-4.0 | 121-300 | 400-450 | Ductile iron |
| Yakakura kudarika kana kuenzana ne6.4 | >300 | 500+ | Simbi isina tsvina 304/316 |
●Special environment adaptation solutions
1. Nzvimbo yakavharirwa: vhiri remaoko rinopeteka (rinopetwa dhayamita 400mm/rakapetwa dhayamita 220mm)
2. Kuputika-nzvimbo inodzivirira: copper alloy handwheel ine graphite lubrication system
3. Tembiricha yakaderera: kaviri-layer hollow structure antifreeze handwheel
5. Size optimization scheme kubva pakuona kweergonomics
●Chikwata chekutsvagisa cheDhipatimendi reMechanical Engineering yeTsinghua University yakaronga dzidziso ye "Golden Ratio":
1.Ideal handwheel dhayamita=upamhi hwechanza chemushandisi × 3.14.
2.Avhareji yehupamhi yemichindwe yevarume vakuru vechiChinese i86mm → dhayamita inokurudzirwa i270mm, inofambirana zvakanyanya nezvikamu zvakajairwa zve300mm muinjiniya chaidzo.
●Makanika ekuedza vanhu anoratidza kuti:
1.Kana iyo dhayamita isingasviki 250mm, kudzvinyirirwa paminwe yeminwe kunodarika 18kPa.
2.Kana iyo dhayamita yakakura kupfuura 450mm, chidimbu chepfudzi chekufambisa chinodiwa chinowedzera ne40%.
6. Kuongororwa kwezviitiko zvemaindasitiri zvinokonzerwa nekukura kusina kunaka
Case 1: Chlorine gasi leakage tsaona mumakemikari chirimwa muna 2023
Root cause: DN200 bhora vharafu ine Φ600mm handwheel
Cheni yetsaona: torque yekushandisa idiki → kuvhura netsaona → kuvhara kwechimbichimbi kunotora nguva yakareba

isa vibration sensor kuti utarise mamiriro ekubereka
Iko kusarudzwa kwakaringana kwesaizi yehandwheel yave nyaya yakakosha mukugadzira mavharuvhu emazuva ano. Nekuvandudzwa kwehunyanzvi hwekuita tekinoroji uye hungwaru hwekunzwa tekinoroji, masisitimu emaoko anozowana chiyero chiri nani pakati pekushanda kwekushanda uye zviratidzo zvekuchengetedza mune ramangwana. Kufembera kwemaindasitiri kunoratidza kuti panosvika 2028, chikamu chemusika che smart handwheels chine inogadzirisa dhizaini mabasa chichapfuura 35%, kuvhura nguva nyowani yeindasitiri vheji yekushandisa interface.
