injection pressure

基本解释

The molder must recognize the dangers of excessive fill speed, insufficient injection pressure, excessive melt temperature, and inadequate packing.
注塑工必須認識過快填充速度、不足注塑壓力、過高融化溫度和不充分擠壓的危害性。
Another benefit is the very short distance from the pot chamber to the nozzle, this means that very little injection pressure is lost during injection.
其另一個優點是從料倉到噴嘴的距離極短，這意味著在注塑過程中注射壓力的損失極小。
Both the shop experiment and field test showed that the wettability alteration agents have the ability to reduce the injection pressure and enhance oil recovery.
室內實騐和鑛場試騐都說明，潤溼性反轉劑具有降壓增注和提高原油採收率的傚果。

The combination of turbocharging and high-pressure direct injection allows Ford to substitute a smaller engine for a bigger one.

Fracking involves the injection of water containing a surfactant and various other chemicals under high pressure into a source rock e.g. shale, causing the latter to fracture and release natural gas (principally methane).

注入壓力
When PEFS and N2 gas are injected into a sand pack water flooded to residual oil state,the injection pressure increases from 0.05 to 2.8 MPa and the oil recovery—from 54% to 79%.
將模型水敺至殘餘油,注入強化泡沫,注入壓力由0.05 MPa上陞至2.8 MPa,採出程度由54%增至79%。
噴油壓力
噴射壓力
A higher injection pressure can increase the vaporization rate,while there is no big difference on the absolute value of the vapor phase mass around the EOI.
高的噴射壓力會提高噴霧的汽化速度,但是對噴射終了時刻氣相質量的絕對值影響不大。

噴射壓力
The results show that the injector with short needle valve can raise injection pressure while insuring the fuel injection system mechanical load unchanged.
結果表明短針閥噴油器在不增加燃油噴射系統機械負荷的前提下，提高了噴射壓力。
