How to determine the cooling water temperature of a reciprocating compressor cylinder block
Thread Content
The reciprocating compressor I am currently using features three stages of compression; the inlet temperature is 30°C and the exhaust pressure is 15 MPa. I would appreciate it if experts could tell me what the appropriate temperature for the cooling water in the cylinder block should be
Just open both the inlet and outlet valves to full capacity
The cylinder controls the inlet temperature of the cooling water to 46 degrees.
The coolant water for the cylinder block is probably taken from the official website; it’s not possible to adjust the temperature of certain components just for one machine. The inlet water temperature can generally be set at the ambient temperature
The typical inlet temperature for circulating water is 32 degrees, while the outlet temperature is 42 degrees. The heat exchange factors were certainly taken into account during the design; it is sufficient to keep the outlet temperature around 42 degrees
What are the inlet temperatures at stage 2 and stage 3 for the poster? The temperature of the cylinder cooling water is generally set at the inlet temperature plus (6–16)°C.
:) Generally, a supply temperature of around 30 degrees and a return water temperature of around 40 degrees is sufficient. In practice, the cooling water in the cylinder has limited effect; it’s good enough as it is
Reply to 6# hgkklzp: The temperature at the secondary inlet is 30°C, at the tertiary inlet it is 35°C, and the highest temperature reached at the tertiary inlet is 44°C.
The water inlet temperature of the cylinder jacket should be ≥46°C, in order to prevent gases such as water vapor in the cylinder gas from liquefying； Return water temperature ≤ 54°C.
The inlet temperature of the cooling water should be 6 degrees Celsius higher than the temperature of the medium entering the cylinder; it cannot be too low
Reply to 8# dengsq: If the inlet temperature is up to 44°C, it can be adjusted to 50°C, as the temperature of the cooling water is generally at least 6°C higher than the inlet temperature, in order to prevent light hydrocarbons from condensing inside the cylinder during compression
