The timing and duration of each valve cycle relative to the hydraulic pressure wave created by the pump can be determined experimentally to achieve stable dispensing operation having the desired droplet size. If the wavelength of the hydraulic pressure wave is too large relative to the valve open ...
Dynamic loading is very common during drilling, mining, hydraulic fracturing, and tunnel excavation. This could compromise the long-term stability and integrity of the underground constructions. Under dynamic loading, rocks usually behave differently compared to static loading. Whether the static failure ...
The calculation method of dynamic capillary force is less discussed in the field of petroleum development, and discussed more in the field of hydraulic dynamics12,13,14. The static capillary pressure pc stat is only a function of fluid saturation. The dynamic capillary pressure pc dyn is a func...
To tackle the challenges of modelling complexities and control specifications, we introduced the evolutionary grey-box model first in 2002, which was validated on hydraulic system and process modelling61. It has since undergone further development and research25,29,35,41,42,64,75,76,97. In the ...

which forces the seal against the side of its groove thereby producing a positive seal on three surfaces. O-rings are usually limited to reciprocating parts having relatively short motion, e.g., a valve spool located in a chamber of an hydraulic circuit. A backup ring is often used with an...
