Definitions
- Each chamber which makes up a multi-camera, must have covers and / or back covers and of course they must have gaskets between each cover and chamber and / or back cover and cover.
- the covers can carry simple packing, which are not injectable, but it has enough difficulty to install or disassemble to tighten the covers or disassemble the covers, being the multi-camera armed.
- the covers are mainly made of steel, they have a large diameter and thickness that can easily weigh 300 [kg] and it is also necessary to have a considerable tightening so that it is very difficult to give the seal with normal gaskets without gas or liquid.
- a simple packing when the pressure is excessive and rises to ultra high pressure and lowers or decreases at atmospheric pressure; it changes its volume so that it has a lot of difficulty in staying tight in the widest range of operation; that goes from 4,000Mpa to atmospheric pressure.
- the tightening is not uniform when they are bolted chambers, it is stronger where the bolt goes and depending on how much it is tightened. For example in a cylinder head with block, it will be different if the bolts have different strength because it has been released. If it is injectable it does not matter, it is always uniformly supported.
- Injectable gaskets which it is necessary to put on the covers of a multi-chamber, it is recommended that in addition to being injectable they are dynamic, since it is automatically injected through valves when the pressure of the multi-chamber rises and gas or liquid is removed from the gasket when it decreases
- the pressure of the multi-camera They are dynamic since the multi-camera is in operation, the dynamic injectable gaskets are constantly injecting liquid or gas when the pressure of the chamber is raised and liquid or gsa is leaving when liquid or gas is leaving the chamber, at different pressure depending on the camera that refer.
- Figure 1 shows the injectable dynamic gaskets (30), which is loaded with gas under pressure, each time the multicam is being charged and discharged each time the multicam is unloaded. It is a multi-camera made of tubes with caps that carry the injectable dynamic packing. It shows half of two cameras that can be 5 or 10.
- a multi-camera in which cameras are installed, one inside the other, so that the innermost cameras withstand a pressure that exceeds the creep stress of the material itself with which it is constructed; they have installed injectable dynamic gaskets.
- the gaskets are dynamic and injectable, since the multi-chamber is in operation, the gaskets are permanently injecting liquid or gas when the pressure in the chambers increases or removing liquid or gas from the gasket, when liquid or gas is leaving the chamber, different pressure depending on the chamber you are referring to.
- Gas or liquid is injected or introduced into the gasket, automatically when the pressure is rising in a chamber, so that the gasket that goes deeper into a multi-chamber, carries more pressure and the gasket that is further out carries less pressure.
- the pressure in the gaskets must also be lowered.
- Each inlet valve to any chamber can have two discharge lines; one that introduces the gas or liquid to the chamber and a check valve that introduces gas or liquid to the gasket; so that the gasket always has the pressure of the liquid that is entering the chamber.
- the gasket of a chamber i is injected through the Xi valve every time the multi-chamber operates at ultra high pressure and exits through the Yi check valve P of the gasket, which discharges at a lower pressure retaining P when the multi-chamber is decompressed, maintaining an internal pressure to the gasket that is at a higher value than the pressure of the i-1 chamber.
- each chamber has and must operate, injecting more pressure or cleaning gas or liquid from inside, every time the multi-chamber is increasing or decreasing the pressure. If at one time you have an ultra high pressure Pa in the inner chamber; the gaskets will have an amount of gas or liquid, but if they are at another pressure Pb, they will have another amount of gas or liquid.
- Gas or liquid gets into the gasket when gas or liquid begins to enter the multi-chamber; that the gas or liquid in the gasket may be other; which is kept in flexible bags outside the packing but inside the chambers. And the pressure of the packing tends to decrease when the pressure of the chambers begins to decrease.
