Problems with screw compressors
Thread Content
For the York screw propane compressors, the technical specifications mention variable specific volume ratio control and energy regulation – both of which are implemented using hydraulic piston actuators. I’m not quite sure how this works; are these two actuators part of the same system or are they separate? Is it the same spool valve or two spool valves? Does adjusting the energy also change the internal volume ratio at the same time? Do the two operate together? Dear experts, could you please explain what’s going on exactly? I would be extremely grateful! ! ! !
Could you explain the process in detail?
In my space, there’s an animation showing the adjustable volume ratio of York industrial refrigeration units~ You can go and take a look for yourself
