Problems with stage regulation in screw compressors
Thread Content
According to this manual for Dalian refrigeration screw compressors, the internal volume ratio can be adjusted only after the internal volume slide valve makes contact with the energy slide valve. Can it be understood that the internal volume ratio can be adjusted only when the load reaches 100%, that is, when it is at its maximum level? Please have an expert analyze this
The movement range of the energy spool is related to the position of the volume ratio spool; when the volume ratio is set to its minimum, the movement range of the energy spool is maximum. In this case, when the energy spool is in close proximity to the volume ratio spool, the compressor is operating at full load
Could you send me a copy of the electronic version of the material from the original poster?
No, the load is stable and can be adjusted at any time; it’s stated in the instructions
Let’s have an expert on screw compressors analyze it; don’t give up
The slide valve is essentially an internal short-circuit valve
