How to handle high-temperature failures in air compressors

Thread Content

Air compressors are mechanical devices; if such high-speed operating equipment does not receive proper lubrication or cooling, it is inevitable that high temperatures will be generated. Excessively high temperatures can cause changes in the physical properties of the rotor and bearing materials, and in severe cases, this can lead to the destruction of the entire compressor unit. This problem can be addressed from two perspectives: first, reducing the heat generated by the air compressor – this requires ensuring high quality in the installation or maintenance of the machine in order to minimize heat production; second, using lubricants that meet the requirements of the equipment. Different models of air compressors may require different types of lubricants, as detailed in the machine’s user manual； Furthermore, the oil supply channels must be unobstructed to ensure proper lubrication, which is a way to reduce heat generation. The second aspect is that the air compressor must be able to dissipate heat properly: whether it is air-cooled or water-cooled, the cooling channels must remain unobstructed, the cooling medium must flow smoothly, and its flow rate must be appropriate – too much of it is a waste, while too little fails to provide adequate cooling ； Furthermore, the space of the air compressor room can be made larger and its height can be increased; this facilitates maintenance, improves air circulation, and is also beneficial for heat dissipation. Large air compressors are fixed equipment, and safety protection is very important. If the overtemperature is severe and the safety protection mechanisms do not activate, it’s not just a matter of the entire unit getting damaged; it can also lead to serious consequences such as equipment explosion. It is relatively difficult to implement safety protections for old-style piston air compressors, but modern screw air compressors are much easier in this regard. They are usually equipped with frequency converters and come with comprehensive electronic protection systems; if there is any issue with the equipment, it shuts down automatically, and a fault record is displayed on the screen right away, which is very helpful for maintenance and repair.
