What is the continuous running time of the air compressor motor in the industry?
There is no unified answer to the question of how long the air compressor motor can run continuously in the industry, because it is related to the type, size, working environment and how to maintain the machine. We can simply understand it according to different types.
Small air compressors, such as those used in laboratories or small workshops, are generally recommended to work continuously for 4 to 8 hours. Because this type of machine is small in size, has limited heat dissipation capacity, and keeps rotating for a long time, the motor is easy to heat up, and the sealing parts inside will age faster. The recommended method is to work for about 4 hours and rest for half an hour, which can not only ensure efficiency, but also protect the machine.
Piston air compressors also belong to the type that requires frequent rest. Its working method determines that it is not suitable for long-term continuous operation. After a period of operation, it needs to stop the machine to cool down, otherwise the motor and internal parts are prone to problems.
The industrial-grade screw air compressor is not the same, they themselves are designed according to long-term continuous operation. In particular, oil-free and water-lubricated air compressors and water-lubricated air compressors, such machines are designed to take into account the needs of all-weather work. Their motors, heat dissipation systems and sealing components have been strengthened, and they can work continuously for 24 hours under normal working conditions, which can fully meet the needs of the factory's all-weather production.
Water-lubricated air compressors have a clear advantage in this regard. Because it uses water instead of oil to complete lubrication during the entire compression process, the motor will not increase the burden due to the increase in oil temperature when the motor is running. The water also plays a lubricating role while taking away heat, so the working state of the motor is more stable. In addition, without the participation of oil, there is no problem of oil deterioration affecting the lubrication effect, and the reliability of continuous operation is higher.
The same is true for oil-free water-lubricated air compressors, because no oil is used, the friction between the motor and the core components is smaller, and the heat generation is lower, so it is more suitable for long-term work without stopping.
However, it should be noted here that even if an industrial-grade machine can run continuously for 24 hours, it does not mean that it can be ignored all the time. Long-term continuous operation of the motor is a great test, if the heat dissipation conditions are not good, such as the machine is full of debris is not ventilated, or the ambient temperature is very high, the motor will still overheat protection or even burn out. Therefore, even if it is a water-lubricated air compressor or an oil-free water-lubricated air compressor, it is necessary to ensure that there is enough ventilation space around so that the heat can be dispersed smoothly.
There is also a very practical advice, that is, don't let a machine work from beginning to end. It is better to let two machines work in shifts, such as one running for a week and the other running, so that each machine has time to rest and the life of the motor and other components will be longer.
In addition, the daily maintenance directly determines how long the motor can run continuously. Regularly clean the air intake filter element, check the heat sink, and replace the consumables that should be replaced on time. These things are done in place, and the motor will run continuously for thousands of hours without major problems. On the other hand, if you leave it alone for several months, you may not be able to run long before you are forced to shut down due to overheating or parts wear.
To sum up, small machines are recommended to work continuously for 4 to 8 hours, and piston-type machines also need frequent rest, while industrial-grade oil-free and water-lubricated air compressors and water-lubricated air compressors can run continuously for 24 hours. However, no matter what kind of machine, heat dissipation should be done well and maintenance should be kept up, so that the motor can run for a long time and run steadily.
