I. Cov Cheebtsam tseem ceeb ntawm cov roj Forklift
Roj forklifts yog cov cuab yeej siv hauv kev thauj khoom thiab chaw cia khoom. Lawv cov qauv tuaj yeem muab faib ua cov hauv qab no:
1. Fais fab mov:
- Cav: Feem ntau yog lub cav diesel (xws li lub cav 4-lub tog raj kheej turbocharged), nrog lub zog ntawm 20-100 horsepower (saib "Forklift Engineering Technical Manual"). Diesel cav muaj cov thermal efficiency ntawm 40%, siab dua cov roj cav (30%).
- Fuel Supply System: Muaj ib lub tank roj (muaj peev xwm ntawm 50-}120 litres), lub twj tso kua mis roj siab, thiab roj injectors.
2. kis tau tus mob:
- Kis: Kev ceev lossis tsis siv neeg (xws li ZF 4WG200), nrog 3-5 nrawm.
- Tsav qag: Nruab nrog qhov sib txawv thiab ntub nres, nrog lub peev xwm ntawm 1-10 tons.
3. Hydraulic System:
- Hydraulic Pump: Iav twj tso kua mis lossis lub twj tso kua mis plunger, nrog lub siab ntau ntawm 150-250 bar.
- Lift Lub tog raj kheej: Stroke 1.5-3 meters, nqa ceev 0.3-0.6 m/s (ISO 2328 tus qauv).
4. Lub cev thiab tswj:
- Overhead Guard: Ua tau raws li OSHA cov qauv rau kev tiv thaiv cov khoom poob.
- Steering Wheel thiab Pedals: Qee cov qauv yog nruab nrog lub zog hluav taws xob.
II. Tej yam Cheebtsam ntawm cov khoom siv hluav taws xob
Siv cov khoom siv hauv tsev ua piv txwv, cov khoom tseem ceeb suav nrog:
1. Cov khoom siv tub yees (xws li cov tub yees):
- Compressor: Reciprocating los yog variable zaus, 80-200W (lub zog efficiency ntsuas A+++).
- Condenser: Copper raj thiab txhuas fin qauv, tshav kub dissipation cheeb tsam 0.5-1.2 m2.
2. Cua Txias:
- Evaporator thiab Condenser: Siv hydrophilic aluminium ntawv ci, ua tiav qhov kev sib pauv cua sov ntawm 60-70%.
- Circuit Board: Main tswj MCU (xws li STM32 series) nrog ntsuas kub ntsuas.
3. Cov Cheebtsam:
- Circuit Court System: PCB thickness 1.6mm, 2-6 copper foil txheej (IPC-6012 tus qauv).
- Cov Khoom Siv Hauv Tsev: ABS yas (kub resistant -20℃txog 80 degree) los yog galvanized steel.
III. Sib piv Kev Ntsuam Xyuas ntawm Roj-Oil Forklifts thiab Cov Khoom Siv Hluav Taws Xob
1. Kev Siv Hluav Taws Xob:
- Roj- roj forklifts siv kwv yees li 3-5 litres ntawm diesel ib teev, thaum cov khoom siv hluav taws xob xws li cua txias siv 0.8-1.5 kWh (cov ntaub ntawv los ntawm US Department of Energy).
2. Tus nqi kho mob:
- Forklifts yuav tsum tau hloov roj tsis tu ncua (txhua 500 teev), thaum cov khoom siv hluav taws xob tsuas yog xav tau kev lim dej (txhua peb lub hlis).
3. Daim Ntawv Thov Scenario:
- Forklifts haum rau hnyav- siv sab nraum zoov, thaum cov khoom siv hluav taws xob tsom rau kev tswj ib puag ncig sab hauv tsev.
