Compressor high-pressure oil and low-pressure oil
Thread Content
Dear teachers, what are the high-pressure oil and low-pressure oil in a compressor, and what are their respective functions?
It is recommended that you clarify the process related to your device; I’m not sure what device you mean, or what it looks like.
For compressors, low-pressure oil serves primarily for lubrication and cooling, while high-pressure oil is responsible for controlling actions such as the opening and closing of valves
The low-pressure oil you mentioned should refer to the lubricating oil for the unit, while high-pressure oil likely refers to the control oil used in the speed control valve
Low-pressure oil should be used for cooling and lubrication, with a relatively low pressure； High-pressure oil is the control oil, responsible for carrying out certain actions
It depends; what the original poster is referring to is probably a turbine combined with a centrifugal unit. Low-pressure oil refers to the lubrication system of the unit, while high-pressure oil refers to the control oil of the steam turbine.
The question isn’t clear enough. In the case of a reciprocating machine with a single support, low-pressure oil is used for lubrication and cooling, while high-pressure oil serves mainly to lift the compressor shaft and provide support. Once the compressor is operating properly, the high-pressure oil pump can be turned off
