On the specific volume ratio adjustment and energy regulation of screw compressors
Thread Content
How do the energy spool valves and volume ratio spool valves operate under different loads? Which boss can explain the process in detail? In other words, during loading (or unloading), which one moves first: the energy spool valve or the volume ratio spool valve? What positions should they be in under different loads? During loading (or unloading), how should these two spool valves operate to ensure a smooth process while also achieving optimal performance? Thank you
Does this version not have a DX for cooling? Top first, then bottom
Our volume capacity remains unchanged after it is set by the manufacturer; only the energy control valve is adjusted

The volume ratio valve does not act easily; it only becomes effective after the energy valve is loaded (that is, when the two valves are in close contact, i.e., under 100% load). 2. When the load is below 100%, the volume ratio valve has no effect (because the distance between the valves allows the incoming gas to bypass the energy valve). But this does not mean that the actual volume ratio remains constant; it’s simply impossible to adjust it. As the energy is adjusted, the actual volume of the unit changes, and the radial outlet also changes as the energy shifts with the movement of the spool, so naturally the volume ratio changes as well. It’s just that the actual volume ratio cannot be detected (it cannot be adjusted independently, so detection is meaningless). 3. In reality, units with an adjustable volume ratio can truly achieve independent adjustment for optimal performance only at loads above 100%; after load reduction, since the position of the energy spool corresponds one-to-one with the volume ratio, adjusting the energy spool also serves to adjust the volume ratio. 4. Therefore, the volume ratio displayed by the unit is not the actual volume ratio at the current time, but rather that at 100% load. The energy load displayed by the unit is not the actual load at that moment, but rather the absolute position of the energy spool; it only corresponds to the actual load when the volume ratio is the same as that with the spool unloaded.
It’s a bit useful; it looks really cool.
I don’t quite understand; let’s see what the experts say
Cow! ! ! One can figure that out! ! !
