Shaxda tusmada
4. Hagaha xulashada taayirrada gacanta ee xaalado kala duwan
5. Nidaamka hagaajinta cabbirka marka loo eego ergonomics
6. Falanqaynta shilalka warshadaha ee ay sababto cabbir aan habboonayn
Dhinaca nidaamyada dhuumaha warshadaha, valves-ka gacanta ayaa ah qaybaha muhiimka ah ee kantaroolka, iyo naqshadeynta aaladaha ay ku shaqeeyaan waxay si toos ah u saameeyaan hufnaanta nidaamka. Marka loo eego warbixinta sannadlaha ah ee 2024 ee Ururka Warshadaha Valve ee Shiinaha, shixnadda sannadlaha ah ee valves-ka ee waddankaygu waxay dhaaftay 23 milyan oo unug, kuwaas oo valves kubbadda oo ku qalabaysan taayirrada gacanta ee caadiga ah ay ka ahaayeen 62%. Iyada oo la dardargelinayo geeddi-socodka warshadaha 4.0, naqshadeynta bani-aadmiga ee is-dhexgalka hawlgalka ayaa noqday tilmaame muhiim u ah hagaajinta qalabka.
Xogta la socodka warshadaha ayaa muujinaysa:
1.45% shilalka hawlgalka goobta {{1} waxay la xiriiraan cilladaha naqshadeynta taayirrada gacanta
2. Hagaajinta cabbirka taayirrada gacantu waxay kordhin kartaa waxtarka hawlgalka 18%

2. Xidhiidhka makaanikada ee ka dhexeeya cabbirka taayirrada gacanta iyo furitaanka iyo xidhidhnimada hufnaanta
● Dejinta qaabka makaanikada
Xidhiidhka u dhexeeya dhexroorka taayiradaha gacantu (D) iyo torque-ga shaqaynta (T) wuxuu raacayaa mabda'a kabaalka:
T = F × D/2
Halka F ay tahay xoogga hawlgalka iyo D ay tahay dhexroorka taayirrada gacanta. Marka wareegga furitaanka iyo xidhitaanka ee looga baahan yahay xidhitaanka waalka la hagaajiyo, kordhinta dhexroorka taayirrada gacantu waxay si weyn u dhimi kartaa baahida xoogga hawlgalka.
● Xawliga saameeya arrimaha
1.Diameter threshold saamaynta: Tijaabooyinku waxay muujinayaan (eeg [3] xogta albaabka gate faahfaahinta) in marka dhexroorka taayirrada gacantu ay dhaafto 400mm, wakhtiga qalliinku wuxuu kordhiyaa 5-8% sababtoo ah korodhka firfircoonida wareega ee ay sababtay cabbirka weyn
2.Friction coefficient doorsoome: Marka la barbar dhigo walxaha naylon ka kooban (μ=0.12), furitaanka iyo xidhitaanka xawaaraha xirmada gacan birta ah (μ=0.25) waxaa lagu dhimay 22% isla dhexroor
3.Transmission ratio optimization: 1: 50 naqshadaynta saamiga dhimista ee qaab dhismeedka gear dixiri waxay kordhin kartaa xawaaraha hawlgalka ee gacan-gacmeedka caadiga ah (Φ300mm) 3 jeer
Xogta tijaabada ah: Baro cabbirka{0}}isku xidhka xawaaraha DN500 waalka kubbadda
Waalka kubbadda DN500 ee loo adeegsaday mashruuca batroolka waxaa loo isticmaalay muunad ahaan (tixraac xogta rakibaadda ee [4]) si loo tijaabiyo furitaanka iyo xidhitaanka waxqabadka cabbirrada gacan-gacan ee kala duwan:
| Dhexroorka taayirrada gacanta (mm) | Wadarta wakhtiga safarka | Awoodda ugu badan ee hawlgalka (N) | Tirada wareegyada |
| 300 | 48.2 | 180 | 12 |
| 400 | 35.6 | 135 | 12 |
| 500 | 42.1 | 108 | 12 |
| 600 | 53.8 | 90 | 12 |
Natiijooyinka muhiimka ah:
Dhexroorka 400mm wuxuu gaaraa xawaaraha ugu sarreeya, isagoo xaqiijinaya saamaynta marinka dhexroorka
100mm kasta oo kororka dhexroorka, xoogga hawlgalka ayaa hoos u dhacaya qiyaastii 25%
Kooxda 600mm waxay leedahay hoos u dhac xawli ah oo ay ugu wacan tahay firfircooni la'aan xad dhaaf ah
4. Hagaha xulashada taayirrada gacanta ee xaalado kala duwan
●Xulashada xulashada xaaladaha shaqada ee caadiga ah
| Cadaadiska dhuumaha (MPa) | Heerkul dhexdhexaad ah ( darajo ) | Dhexroor lagu taliyay (mm) | Ikhtiyaarada alaabta |
| In ka yar ama la mid ah 1.6 | -20~120 | 300-350 | Aluminium tuur birta kabka ah ee la xoojiyay |
| 2.5-4.0 | 121-300 | 400-450 | Bir-mareenka |
| Ka weyn ama la mid ah 6.4 | >300 | 500+ | Birta aan la isku dhejin 304/316 |
●Xalalka la qabsiga deegaanka ee gaarka ah
1. Meel xaddidan: taayir gacanta laalaabi karo (dhexroor 400mm/ dhexroor laablaaban 220mm)
2. Qaraxa{1}}aagga cadaymaha:
3. Xaaladaha heerkul hoose: labanlaab{1} qaab dhismeedka lakabka godan ee ka hortagga barafka gacanta
5. Nidaamka hagaajinta cabbirka marka loo eego ergonomics
●Kooxda cilmi-baarista ee Waaxda Farsamada Farsamada ee Jaamacadda Tsinghua waxay soo jeediyeen aragtida "Golden Ratio":
1. Dhexroor taayir gacanta ku habboon=ballaca calaacasha ee hawlwadeenka × 3.14.
2. Celcelis ahaan ballaca calaacalaha ee ragga waaweyn ee Shiinaha waa 86mm → dhexroorka lagu taliyay waa 270mm, kaas oo si aad ah ula socda qaybaha caadiga ah ee 300mm ee injineernimada dhabta ah.
●Tijaabooyinka makaanikada aadanaha ayaa muujinaya in:
1.Marka dhexroorku ka yar yahay 250mm, cadaadiska kala goysyada farta ayaa ka badan 18kPa.
2.Marka dhexroorku ka weyn yahay 450mm, kala duwanaanshaha wadajirka garabka ee shuruudaha dhaqdhaqaaqa wuxuu kordhiyaa 40%.
6. Falanqaynta shilalka warshadaha ee ay sababto cabbir aan habboonayn

Xulashada saxda ah ee cabbirka taayirrada gacantu waxay noqotay arrin xudun u ah naqshadaynta waalka warshadaha casriga ah. Horumarinta tignoolajiyada shay cusub iyo tignoolajiyada garashada caqliga leh, nidaamyada taayirrada gacantu waxay gaari doonaan dheelitirnaan wanaagsan oo u dhexeeya waxqabadka hawlgalka iyo tilmaamayaasha badbaadada mustaqbalka. Saadaasha warshaduhu waxay muujinayaan in marka la gaadho 2028, saamiga suuqa ee taayirrada gacanta ee caqliga leh ee leh hawlaha hagaajinta la qabsiga ay dhaafi doonto 35%, furitaanka xilli cusub oo ah interface hawlgalka waalka warshadaha.
