Determination of the oil heat exchange amount in the air-cooled cooler for screw compressors
Thread Content
In a screw compressor with an air-cooled cooler, how can one determine whether the heat transfer amount on the oil side has been achieved? ? Just check the inlet and outlet temperatures? Since the flow rate on the oil side of the compressor is generally not very precise, it is difficult to determine whether the heat transfer capacity of the cooler has been met ?
What is the purpose of understanding the heat transfer amount? Why must one know? What’s the point of insisting on a certain heat transfer amount when the operating conditions are different?
For air compressor users, it might not matter the heat transfer capacity, only the temperature. For design and manufacturing, calculations are required.
I’m sorry, but I’m no expert on air compressors. However, the power of the motor is fixed; what consequences will occur if the heat transfer capacity of the cooler is not sufficient, that is, if the temperature difference is too small? ? Isn’t there such a standard for air compressors? ?
Are you referring to the temperature difference between oil import and export? ? What temperature difference is considered acceptable? ?
The heat transfer rate can be calculated during design based on the desired temperature and certain operating conditions. In actual operation, the conditions may not necessarily be at their maximum; it is still necessary to determine, based on a certain temperature, whether the requirements are met and whether the heat exchanger is functioning properly
The process proposes the calculations for design and manufacturing
