Oil-free air compressor is a kind of efficient and hygienic air compressor, compared with the traditional oil air compressor, oil-free air compressor does not need to use lubricating oil to lubricate and cool the cylinder and piston, so it can effectively reduce the pollution to the environment during the application process, and there is no need to change the lubricating oil frequently, and the maintenance cost is low.
However, even for oil-free air compressors, the piston is still an important component. The piston is one of the core components in the oil-free air compressor, which plays the role of compressed air. Therefore, when the piston is seriously worn or fails, it is necessary to replace the piston in time to ensure the normal operation of the oil-free air compressor.
So how do you tell if the piston needs to be replaced? First, we can tell by looking at the appearance of the piston. If the piston surface shows significant wear, scratches, or deformation, then it is likely that the piston needs to be replaced. In addition, if there is a gap between the piston and the cylinder, or there is a leak between the piston and the seal ring, it also needs to be replaced.
In addition, we can also determine whether the piston needs to be replaced by checking the performance of the oil-free air compressor. If the compression capacity of the oil-free air compressor is found to be significantly reduced during use, the compression ratio is too high or too low, and the noise increases, it is likely that there is a problem with the piston and it needs to be replaced.
When we find that the piston needs to be replaced, how should we operate? First, we need to get the new piston ready. When choosing a new piston, the same specifications as the original piston should be selected, and the quality is reliable. Then, we need to cut off the power of the oil-free air compressor and exhaust the compressed air in the cylinder. Next, you need to remove the cylinder head and connecting rod, and remove the original piston. When removing the original piston, care should be taken to avoid damaging other parts. Then, install the new piston into the cylinder and ensure a tight fit between the piston and the seal ring. Finally, reinstall the cylinder head and connecting rod, and check that the piston is installed correctly.
It should be noted that the replacement of the piston is a simple replacement work, and it also needs to be stable during operation. Operators should wear personal protective equipment and follow operating procedures. If you are not familiar with the operation process or have no relevant experience, ask technical personnel to replace the fault.
In summary, the piston of the oil-free air compressor may wear or fail after long-term use, and it needs to be replaced in time to ensure the normal operation of the machine. The replacement of the piston needs to pay attention to safety, and ensure the selection of a new piston with reliable quality, to ensure the accuracy and stability of the replacement process, and to extend the service life of the oil-free air compressor.
