How to maintain nitrogen compressors?

Maintenance work is a crucial part of any machinery and equipment. In order to play a stable product characteristics, and to extend the service life of the product. Regular maintenance and inspection of machinery and equipment is required. Today we will introduce how to repair the nitrogen compressor with the characteristics and working principle of nitrogen compression.

·Compressor Oil Break

An oil or water cutoff in a compressor is a common failure. This fault phenomenon occurs when the discharge temperature and pressure exceed the set values and the control system, in order to protect the nitrogen compressor, automatically issues an alarm, resulting in a delay and shutdown. For this situation, we recommend using one piston body per stage. When a problem with the guide ring is found during the inspection, it is necessary to reheat a new ring. In the meantime, the spare piston body can be used directly.

·Interstage Pressure Anomalies

Nitrogen compressors may experience interstage pressure abnormalities after a long period of operation. The main manifestations of interstage pressure abnormalities are cylinder wall wear, and the elastic ring may break into pieces, resulting in valve leakage. In addition, the most direct manifestation of the interstage pressure abnormality is that the discharge pressure and temperature are high and then drop, that is, the discharge pressure and temperature are abnormal.

For this situation, be sure to shut down the equipment for inspection. Check the valves of each stage carefully, remove the elastic ring of all stages, restore the normal use, and remove the elastic ring machine on the oxygen, and then reuse it.

In summary, there are many other common failure phenomena of nitrogen compressors, so I won't list them here. But for all the failure situations, we can avoid them in advance, that is, regular inspection of equipment components. At the same time, there are still some considerations to be taken into account when using the compressor.

The working principle of nitrogen compressor

The working principle of a nitrogen compressor is very easy to understand, after the air enters the compressor. After the air enters the compressor, it passes through a filtration system in the nitrogen compressor, which filters out some of the air, such as oxygen. After the nitrogen compressor has finished its work, high purity nitrogen will be discharged.

What are the precautions for a nitrogen compressor?

When using nitrogen compressors to compress air for industrial processes, quality control is of critical importance. In addition to this, there are a number of important factors that need to be taken into account, which are highlighted in this section.

·Regular inspection of components

First of all, we need to clean the product components regularly to prevent foreign objects from entering the equipment. For example, if the oil filter is clogged, it can lead to equipment downtime, which can result in financial losses and unnecessary maintenance budgets.

·Check in use

When the compressor is in normal operation, check every half hour, check, listen and touch the compressor. Check the oil level of the moving parts, machine parts and valves in the compressor, especially the oiler, whether there is oil or not is an important factor. At the same time, it is equally important to adjust the oil level in time. It is noteworthy that when the catalyst in the compressor equipment needs to be replaced, be sure to notify the professional staff, it should not be operated by yourself.

In summary, these are the main considerations for nitrogen compressors. Although the structure of nitrogen compressors is relatively simple, there are still safety factors to consider when operating them. In addition, although nitrogen does not support combustion, some extremely active metals can be burned in nitrogen, so it is very important to pay attention to safety.
