Raws li hom tshwj xeeb ntawm lub twj tso kua mis, cov twj siv dej hiav txwv muaj cov yam ntxwv hauv qab no piv rau cov twj dej zoo tib yam:
Cov ntaub ntawv qib siab - qib: Lub twj tso kua mis lub cev ntawm lub twj tso kua mis dej hiav txwv feem ntau yog ua los ntawm qib siab - qib ABS nrog ultrasonic molding, thiab lub twj tso kua mis yog ua los ntawm cov hlau tsis muaj steel, ua rau nws ruaj khov, hnav- tiv taus, thiab corrosion- tiv taus, haum rau kev siv dej tshiab thiab dej hiav txwv.
Hnav tsis kam: Vim tias dej hiav txwv yuav muaj cov khoom me me, xws li xuab zeb thiab coral, lub impeller tshem tawm ntawm cov twj dej hiav txwv loj dua, txawm tias cia cov khoom me me dhau mus, ua rau muaj zog hnav tsis kam.
Corrosion resistance: Seawater muaj ntau cov ntsev thiab lwm yam tshuaj. Cov twj siv dej hiav txwv feem ntau yog ua los ntawm cov khoom tshwj xeeb corrosion-cov ntaub ntawv tiv taus, ua kom muaj kev ruaj khov nyob rau hauv ib puag ncig marine rau lub sijhawm ntev.
Cov zis ruaj khov: Lub impeller hauv lub twj tso kua mis dej hiav txwv yog qhov sib luag hauv nruab nrab, tsis zoo li cov twj diaphragm lossis cov twj piston uas siv lub log eccentric, uas ua rau yuav luag tsis muaj qhov tshwm sim "pulsation".
