Seeking help regarding the excessively high exhaust temperatures at the first and second stages of the membrane press

Excessively high exhaust temperatures are usually related to the following factors: 1. **Cooling system issues**: Although you mentioned that the water cooler was in good condition, it is recommended to check again whether there is sufficient flow of cooling water, whether the water temperature is appropriate, and whether there are any blockages or problems with circulation within the cooling system. 2. **Lubricant issues**: Check whether the type and grade of the lubricant meet the machine’s requirements, as well as the oil temperature and quality, including whether there is contamination or insufficient oil levels. Proper lubrication can effectively reduce the heat generated during compressor operation. 3. **Compressor load**: Verify whether the compressor is operating at its rated load. Overloading the compressor will cause it to overheat. 4. **Internal leakage**: Check for leaks inside the compressor, especially during the compression stage; leaks can lead to reduced compression efficiency and increased temperatures. 5. **Intake air temperature**: Although you mentioned that the intake air temperature is normal, it is recommended to check whether there are any changes in the surrounding ambient temperature. Excessively high ambient temperatures directly affect the intake air temperature and, accordingly, the exhaust gas temperature. If the problem persists after the above checks, it is recommended to contact the manufacturer’s technical support for further analysis of possible causes and solutions. At the same time, considering the installation of an additional cooling system or optimizing the existing one can also improve the cooling effect. .
