Flow in injector passages of a variable thrust liquid propellant rocket engine was studied.
To design a high performance injector and to improve engine impulse performance are the permanent goals of engine designers.
By theoretical analysing and calculating, we find the short needle valve fuel injector can further decrease the impact stress of the needle valve to the sealed conical surface.
Conclusion the modified method significantly improves the puncture success rate of inserted intravenous injector in newborn; and it is earlier to keep in scalp vein than in great saphenous vein.
A key part of the neutral beam injector is ion beam system, whose property defines the efficiency and effect of the neutral beam injector.
You will get more control if your injector can introduce messages at a set rate.
The injector base, fabricated by metal casting and stamping, is an important part in automobile oil circuits.
And the content of capillary ion chromatography instrument includes micro-flow pump, injector, suppressors, conductometric detectors, UV-Vis detectors and fluorescence detectors with small volumes.
The small lower hole is that for the injector.
The solution: Need to check the atomization of the injector and the intake pipe is smooth or not.
The Rupe number and the ratio of injection orifice diameter are two key parameters affecting unlike impinging injector performance, and they are closely interrelated.
We will go ahead as quickly as we can, now we have developed many kinds of machines . Such as, filler, sealing and clipping machine, saline injector, meat mincer machine and so on .
The invention relates to an injector for medical purposes and particularly popularizes an injector which has an injection rod, a syringe and a syringe needle that can be fully self-destructed.
In this work, the line pressure at fuel pump side and at injector side, nozzle needle lift and sound velocity of dimethyl ether (DME) were measured to evaluate DME injection process.
Some stratification exists in the spray produced by any liquid propellant injector.
In this paper, the fuel gas and propellent system of "in site" Pellet injector used in beforehand experiment and Pellet fueling experiment in HL-1 Tokamak has been introduced.
The impact of repetition on Gas Chromatogram was studied with glass wool in glass injector insert and different concentration samples.
The application of a pressure difference across an injector does not cause an immediate velocity response of the liquid propellant.
So the electronic controlled test system is the necessary device for the carmaker and reparative factory to test and adjust the injector.
Using different injection rates, double-syringe power injector and saline flushing following contrast material bolus…
The gooseneck mounted on top of the injector head feeds the tubing string from the reel around a controlled radius into the injector head.
