6. Cov lus nug nquag nug (FAQ)
Q1: Dab tsi yog qhov nruab nrab lub neej ntawm lub twj tso kua mis hydraulic hauv cov tshuab siv hnyav?
Nyob rau hauv ib txwm hnyav- daim ntawv thov kev tsim kho, lub siab- zoo cam khwb cia- hlau iav twj tso kua mis kav li ntawm 3,000 txog 5,000 teev ua haujlwm. Lifespan nyob ntawm kev huv huv ntawm cov kua dej (lub hom phiaj ISO 4406 kev huv huv code 18/16/13), cov roj viscosity zoo, thiab cov dej ua haujlwm kub hauv qab 80 degree.
Q2: Kuv puas tuaj yeem hloov lub twj tso kua mis txhuas iav nrog lub twj tso kua mis hlau rau ntawm kuv lub excavator?
Yog lawm. Hloov lub twj tso kua mis txhuas iav nrog lub twj tso kua mis hlau cam yog muaj nyob rau hauv hnyav - lub luag haujlwm retrofits. Cam khwb cia hlau lub cev muaj zog siab dua, tsis muaj vaj tse nyob rau hauv thermal shocks, thiab ntau dua durability tiv thaiv abrasive contamination, muab mounting flange thiab ncej qhov ntev match.
Q3: Dab tsi yog qhov laj thawj tseem ceeb ntawm kev ua haujlwm ntxov ntawm hydraulic iav twj tso kua mis tsis ua haujlwm?
Peb qhov ua rau sab saum toj yog cov kua dej paug (particle abrasion), aeration / cavitation (tsis txaus suction inlet siab ua rau iav hniav pitting), thiab tshaj -pressurization / thermal shock (ua rau lub foob foob foob los yog sab phaj warping).
