motor cavity 中文意思是什麼
motor cavity
解釋
電動機座穴-
To simulate the quiescence and flying status of the motor, the ablation is calculated with different cavity width
為模擬發動機靜止與飛行兩種不同狀態，本文對不同寬度的槽縫人工脫粘層的燒蝕進行了計算，對其進行了比較。 -
After igniting the motor, the combustion gas coming into the debond cavity may expand the debond cavity, and make an additional combustion area and lead to larger load
發動機點火后燃氣進入脫粘腔，使脫粘腔變形並獲得額外的燃燒面積，從而導致更強的載荷。 -
The simulations results show that the spoiler is available to make the fuel and the oxidizer coming from the former to stay in the cavity for a long time, to let the fuel and oxidizer mix and burn completely. since there is a high temperature zone forming by vortex in the middle of the motor, it required a restricted thermal protection. the plate with holes decreased the vortex function in the cavity, which could not promote the combustion efficiency, but to decrease temperature in the cavity and be benefit to thermal protection of the wall
計算結果分析表明:擾流板可以使燃料和氧化劑在擾流腔內的滯留時間加長，促進燃料與氧化劑的摻混燃燒，提高燃燒效率，但由於渦流在發動機的中間部位形成了高溫燃燒區域，致使局部燃料和絕熱層燒蝕速率增大，加大了熱防護的難度;孔板結構減弱了擾流腔內迴流區的漩流作用，不能增加推進劑燃燒效率，但可以使擾流腔內的溫度降低，給壁面熱防護帶來好處。 -
The plastic mould with the thickness over 400mm ; mould for closure of tv sets and trunks ; mould for closures of copying machines ; mould for vibration absorber ; mould for motor dashboards and large parts ; mould for dustbins ; mould cavity for die cast
厚度大於400mm的塑料模具電視機罩殼和后備箱的模具復印機外罩的模具減震器的模具汽車儀錶板和大型零部件的模具垃圾箱模具壓力鑄造型腔 -
But, at the present situation, the down hole progressing cavity pump is driven by the motor and reducer placed on the ground via a thin and long rod, and this cause troubles easily because of the rod works in cycling bending and distortion
目前螺桿泵採油系統採用地面電機和減速裝置通過細長抽油桿驅動井下螺桿泵，這種驅動方式由於抽油桿旋轉時處于長期循環扭曲狀態，系統很容易出現故障。 -
By analyzing the different kinds of in use reducer and integrating the current research and considering the down hole operating condition, a kind of closed loop power distributional planetary gear reducer is put forward as a proper reducer to directly connecting the motor and the progressing cavity pump
對目前使用的各種減速器進行結構分析和論證，結合國內外的研究和設計情況，並根據井下螺桿泵的工作條件，提出封閉式功率分流行星減速器作為聯接潛油電機驅動螺桿泵工作的減速器的方案。
