When a fluid reaches a pressure so low that it evaporates, it causes cavitation. Cavitation is when gas bubbles form inside of a fluid because this critical low pressure evaporates some of the fluid. The problem is, that when the bubbles get big enough and reach a higher pressure, the gas inside of the bubbles turns back into fluid form, so it leaves vacuum behind. The surrounding fluid rushes into the spot with the speed of sound, and this creates an implosion. Cavitation is really dangerous because it can literally eat metal over time.

Basically he adds enough pressure to avoid the cavitation even though system has to move oil back and forth quickly. The flowing oil experiences a pressure drop across it's path and if this drop is too high the oil in the cylinder experiences vacuum. The faster the system has to move, the higher the pressure he needs to avoid cavitation. Shouldn't be many bars, just a few, guessing 3-4?

I call "Fake Demo" on this. The cavitation is happening on the rebound side of the shock chamber. The rebound damping is typically much less than compression damping, and the max rebound rate is dependent on how hard the spring pulls the damper apart. In this case, the demo shows a machine pulling the damper apart which I would suspect is much harder than a spring would. Without numbers, this is just a "magic" demo to help sell you something. MO.

This is true cavitation. The pressure on the low side vaporizes. If a pump or prop sucks in air from the surface it’s not cavitation it’s ventilation.
@PaulG.x6 ай бұрын
True cavitation occurs in pumps and marine propellers where the fluid flow over parts of the device cause low pressure areas that exceed the cavitation threshold. The trailing edges of marine propeller blades are quite susceptible to this and it can cause erosion of the metal the blade is made from. It's analogous to vapour trails that appear from parts of aircraft wings in humid air

Pitting is correct, this can happen when pumping fluids. Cavitation can damage the impeller and pump housing over time if allowed to continue. The excavated material becomes suspended in the fluid. In a small volume of fluid like a strut, the suspended material will damage seals.

How does the reservoir experience so much pressure change (shown with the up/down motion of the diaphragm on the right) if the oil is simply transferring from one side of the main piston/valve to the other? Is there that much expansion of the fluid due to pressure effects? Because in my mind there isn't air or anything replacing the low pressure space of the main valve as it moves through the stroke transferring oil through the compression valve into the reservoir. I'm trying to understand the mechanics of this better. thank you!

The piston isn't a complete seal. There are holes in the piston with stacks of small thin washers which are usually adjustable. They control oil flow. Damping is controlled by how fast oil is allowed to pass from one side of the piston to the other. The oil on the negative side will have a slight vacuum if the oil on the compression side can't travel through fast enough to fill the void/vacuum so they pressurize the whole system preventing the cavitation.

@ShivaShakur6 ай бұрын
There is no extra air that was sucked in, the cavitation is only "bubbles" created by the super fast movement (too fast for the fluid's thickness and its surface tension to manage "pulling itself back together") This is creating really low pressure zones, allowing space between groups of molecules of the shock fluid, and it isn't able to revert back into being homogeneous - that is until the pressure is applied (This is a bad explanation I'm sorry, not a physicist) look up other videos/explanations of cavitation if you want to know more, it is fascinating and can erode and destroy equipment such as boat propellers or even diesel engines

Is that the purpose of those shocks with canister? I've always thought it was mor like a secondary suspension like when having maximum load or something. But int he demonstration they release the air and add the air back in, normally therea just a fix amount of air and vreasure in that canister right, or does it need topping up periodically or something to maintain a certain pressure for it to work against the cavitation?
@jensenmiller6410 Жыл бұрын
The pressure in the nitrogen reservoir typically stays fixed until the sealing components wear out over a long time (possibly shorter under extreme use conditions). You don't want to try measuring the pressure in the cannister after it's pressurized since the amount of nitrogen that flows into the gauge will be enough to drop the pressure a good amount and require a refill. Shocks without the reservoir will typically still be pressurized, but the bladder is internal. Having the reservoir separate from the main tube is useful but for reason's I don't remember at this current time.
@sammather575110 ай бұрын
The piggy back or canister provides extra oil and surface area for cooling as well as giving the designers more space to add the valving and adjusters. An in-line shock with no canister still has a gas charge in it.
@1wheeldrive75121 күн бұрын
No. The piggy back canister is where the gas charge is. You need a gas volume because hydraulic fluid is essentially incompressible. Every stroke of the shock puts more or less of the shaft into the oil chamber, which will displace the volume of the shaft. If there were no gas chamber the body of the shock would explode under the oil pressure. The gas chamber gives the displaced oil somewhere to go.
