Why is the temperature high in the three rows and low in the four rows of the 6MD32 reciprocating compressor for coke oven gas?

The temperature is high in row 3 and low in row 4; why does increasing the amount again after reducing it help for a while, while the temperature of the air valve isn’t high? The pressure in the three rows has also increased, but the volume remains unchanged
Check the inter-cooler and the cylinder block cooling jackets; it’s likely that they are blocked, which causes the temperature to rise, and the pressure will surely increase as well
The fourth-stage intake valve is probably broken; take it apart for inspection
All components are removed for cleaning and maintenance; in particular, debris inside the flow channels is cleared, and the valve plates and springs are replaced. Fill each valve plate with water before reinstalling it to check for leaks.
