Air compressor is a kind of equipment used to compress gas. The structure of air compressor is similar to that of water pump. Most air compressors are reciprocating plug type, rotating blades or rotating screws.
It is understood that the performance of the air compressor cooling system directly affects the service life, maintenance cycle and work efficiency of the air compressor. Therefore, in the daily maintenance, we should combine the theoretical knowledge and practical experience to effectively ensure the safe and economic operation of the air compressor, and provide a strong guarantee for the continuous and stable supply of compressed air.
The influence of cooling system on air compressor, the core part of air compressor operation is compression. Air compressor consumes technical work in the compression process, which will produce a lot of heat, which affects the operation of air compressor. During the operation of the air compressor, there are many impurities in the cooler tube bundle, such as plastic bags, filler fragments, welding slag, etc. these impurities are very easy to cause the blockage of the cooler pipeline and reduce the cooling efficiency. For example, during the operation of centrifuges in our workshop, welding slag, plastic bags, fillers and other debris blocked the cooler, which were not well protected during the construction, so that these debris entered the cooler.
Influence of cooling effect on air compressor:
1) Shortening of service life: the cooling effect of the air compressor is poor, which will lead to many problems, such as: (a) the increase of oil temperature makes the lubricating oil thin and the pressure decreases, which leads to the decrease of the lubrication effect of the compressor head, the aggravation of the wear of the head parts, and the shortening of the service life. (b) If the primary compressed high temperature air is not completely cooled by the cooler or the cooling temperature is not suitable, it will not only increase the technical work required for the next stage of compression process, but also cause the compressor head fatigue damage.
2) Shorter maintenance cycle: poor cooling effect of air compressor will lead to higher temperature of air compressor, oil and dust in the air will produce colloidal mixture such as oil scale under high temperature, and these substances are easy to pollute and damage related accessories, which will lead to shorter maintenance cycle of air compressor.
3) Working efficiency reduction: when the water temperature of the cooling system is too high, the compressed air is not completely cooled in the cooler or the cooling is not in place, which causes the high temperature expansion of the compressed air in the compressor head, resulting in the reduction of suction volume, exhaust volume and the working efficiency of the whole air compressor.
