Cov Hom Hlau Tseem Ceeb rau Cov Cheebtsam Hydraulic Xovxwm thiab Lub Tog Raj Kheej
1Ncej thiab kem hlau: Q235 thiab Q345 Cov khoom
Lub thav duab hydraulic txhawb nqa tag nrho cov qauv tshuab. Nws yuav tsum muaj kev ruaj khov siab thiab weldability zoo. Q235 hlau yog ib qho kev xaiv rau cov chav hydraulic xovxwm qis-tonnage. Cov hlau no muaj lub zog tso zis ntawm 235 MPa. Nws pheej yig dua thiab ua tiav yooj yim. Txawm li cas los xij, Q345 hlau ua haujlwm zoo dua rau cov qauv hydraulic xovxwm nruab nrab thiab loj. Q345 muaj 345 MPa lub zog tso zis. Nws muaj manganese thiab silicon rau ntxiv lub zog. Cov kws ua haujlwm xaiv Q235 rau kev tsim qauv tswj kev nruj. Lawv xaiv Q345 rau cov qauv tswj kev ruaj khov.
Lub tshuab hydraulic press kem xa lub zog los ntawm lub tog raj kheej mus rau qhov workpiece. Q345 steel txo qhov hnyav ntawm cov khoom siv thaum tseem tswj tau lub zog. Qhov no txo tus nqi tag nrho ntawm lub tshuab hydraulic press.
2Lub Tog Raj Kheej Hlau Loj: 45 # Hlau thiab Cov Kev Xaiv Alloy
Lub tog raj kheej hydraulic presses tiv taus qhov siab sab hauv. Kev xaiv cov khoom siv cuam tshuam rau lub neej ua haujlwm thiab kev nyab xeeb. 45 # hlau haum rau cov tog raj kheej hydraulic dav dav. Nws lub zog tensile ncav cuag 600-800 MPa. Tus nqi tseem qis. Tab sis 45 # hlau muaj qhov nyuaj tsawg. Cov khoom tuab dua 30 hli yuav muaj cov tub ntxhais mos.
Rau kev ntxhov siab ntau dua, cov engineers xaiv 27SiMn lossis 42CrMo alloys. Cov ntaub ntawv no muaj kev tiv thaiv kev qaug zog zoo dua. AISI 4140 steel zoo heev hauv kev siv hydraulic siab. Nws muab lub zog tensile siab dua 1000 MPa. Qhov no ua rau nws zoo tagnrho rau cov tshuab hydraulic hnyav.
3Cov Khoom Siv Piston Rod: Kev Kho Mob Hnav thiab Kev Kho Mob Corrosion
Lub hydraulic xovxwm piston pas nrig txav mus los tas li. Nws xav tau qhov nyuaj ntawm qhov chaw thiab tiv taus corrosion. Tus qauv 45 # hlau nrog chrome plating ua haujlwm rau feem ntau daim ntawv thov. Lub chrome txheej ntsuas 20-50 microns tuab. Qhov no tiv thaiv xeb thiab txo kev sib txhuam.
Rau qhov chaw ib puag ncig hnyav, 42CrMo lossis 17-4PH stainless hlau ua haujlwm zoo dua. Cov ntaub ntawv no tiv taus kev hnav los ntawm cov voj voog siab. Hauv kev lag luam zaub mov lossis kev lag luam marine, 316 stainless hlau tiv taus chloride corrosion zoo. Kev ua haujlwm ntawm hydraulic xovxwm nyob ntawm kev xaiv cov khoom siv pas nrig kom raug.
Kev Sib Piv Kev Ua Haujlwm ntawm Cov Khoom Siv Hlau rau Cov Ntawv Thov Hydraulic Xovxwm
AKev Sib Piv ntawm Cov Hlau Ua Vaj Tse: Q235 vs Q345 Lub Zog thiab Tus Nqi
| Vaj tse | Q235 | Q345 |
|---|---|---|
| Lub Zog Tawm | 235 MPa | 345 MPa |
| Kev vuam | Zoo heev | Zoo (yuav tsum tau ua ntej kom sov) |
| Tus nqi | Qis dua | Siab dua me ntsis |
Q235 haum rau cov thav duab hydraulic me me. Nws vuam yam tsis muaj cov txheej txheem nyuaj. Q345 haum rau cov qauv hydraulic loj dua. Lub zog siab dua tso cai rau cov ntu nyias dua. Qhov no txo qhov hnyav thiab tag nrho cov nqi txawm tias tus nqi khoom kim dua.
BKev Ua Haujlwm ntawm Alloy Steel: 45 # Steel, 40Cr, thiab 42CrMo Daim Ntawv Thov
| Qib Hlau | Lub zog tensile | Siv Tau Zoo Tshaj Plaws |
|---|---|---|
| 45 # Hlau | 600-800 MPa | Cov khoom siv hydraulic me me |
| 40Cr | 800-1000 MPa | Cov pas nrig hnyav |
