groove face

基本解釋

A study on the static performance mechanism of a new double spiral groove face seal was done.
研究了一種新型雙列螺旋槽機(jī)械密封結(jié)構(gòu)的工作機(jī)理。
The results of calculation indicates that the static axial stiffness of fluid film in double spiral groove face seal is improved due to the pressure loss through feeding holes.
計(jì)算結(jié)果表明，供液小孔所產(chǎn)生的壓力損失提高了雙列螺旋槽機(jī)械密封的靜態(tài)軸向剛度。
Seal chamber pressure of a new double spiral groove face seal working under high velocity and pressure conditions may probably be disturbed in operation, which affects the seal stability.
一種用于高速高壓等極端工況下的新型雙螺旋槽端面密封在實(shí)際運(yùn)行過(guò)程中密封腔壓力會(huì)出現(xiàn)波動(dòng)，從而影響密封穩(wěn)定性。

That evening, having slept through the dinner hour in his cell, with his face pressed against a cool groove on the floor, Pascal saw a line of black shiny boots marching toward him.
