How To Distinguish Between Old And New Compressors

To differentiate between a new compressor and an old or refurbished one, specialized knowledge and skills are required. This process is similar to identifying RMB (Renminbi) bills and coins. It is vital to be familiar with the components, manufacturing processes, and general characteristics of new compressors to identify any reworked or repaired models accurately. Therefore, it is crucial to consult with experts or professionals who possess the necessary proficiency and experience to determine the authenticity and quality of compressors.

 

To ensure consistency, it is recommended to measure the winding resistance of two identical machines using a meter. This is especially important for new machines. Make sure that the readings are consistent between the two machines.

 

When purchasing a machine, it is important to check for any strong odors coming from the high-pressure port during pressure testing. Additionally, you can test the exhaust port for any discoloration with an open flame. If the flame is yellow, it indicates that the machine has not been used. However, if there is any discoloration, it means that the machine has already been filled with fluorine, even if it has been cleaned with any solvent. It is important to perform these checks to ensure that you are receiving a machine that is in good condition.

 

The new original compressor is coated with water-soluble or fluorocarbon paint, which imparts a remarkably smooth and even surface. Even in high-temperature surroundings, the paint remains non-sticky and devoid of any unpleasant odor. It's worth mentioning that small-scale manufacturers, who are unable to match this level of quality, predominantly produce refurbished machines.

 

Trademark is another important factor to consider when determining the authenticity of a machine. The trademark on the original device is characterized by neat and legible handwriting, the use of appropriate fonts and a well-balanced pattern ratio. Additionally, there should be no rough edges or burrs on the trademark. It's also crucial that the model mentioned on the nameplate matches the actual machine. If these criteria are not met, there is a possibility that the machine is a refurbished one.

It is quite simple to distinguish a brand new compressor from another based on a few key factors. Firstly, during the production line, the high and low pressure nozzles of the compressor undergo high-frequency welding. This welding process ensures a secure and durable connection between the nozzles and the compressor body. Additionally, all the pipes used in the compressor are brand new, with no welding slag present on the inner wall. This ensures smooth air flow and optimal performance. By examining these characteristics, it becomes evident whether a compressor is truly original and untouched.
