Kev Xeem Xeem

Hydrostatic xeem

Cov yeeb nkab kom tiv taus qhov kev sim hydrostatic yam tsis muaj qhov xau los ntawm cov hlua khi los yog cov yeeb nkab lub cev. Jointers tsis tas yuav tsum tau kuaj hydrostatic muab cov yeeb nkab seem siv tau zoo kuaj.

Khoov xeem

Tsis muaj kab nrib pleb yuav tsum tshwm sim nyob rau hauv ib feem ntawm daim ntawv xeem thiab tsis muaj qhov qhib qhov vuam yuav tsum tshwm sim.

Kev ntsuam xyuas

Kev lees txais cov qauv rau kev kuaj flattening yuav tsum yog:

EW cov kav dej D <12.750 hauv:
X60 T 500 in. Yuav tsum tsis txhob qhib qhov vuam ua ntej qhov kev ncua deb ntawm daim hlau yog tsawg dua 66% ntawm qhov qub sab nraud txoj kab uas hla. Rau txhua qib thiab phab ntsa, 50%.
