1, gap enlargement
The distance between the A and the rotors of the Yin and Yang of the main engine increases. The direct consequence is that the compressor leaks during the compression process (i.e., back leakage), and the volume of compressed air discharged from the compressor becomes smaller. In terms of efficiency, compression efficiency of compressors is reduced.
The gap between the B, the Yin and Yang rotor and the rear end cover and the bearing is increased, which will affect the sealing and compression efficiency of the compressor. At the same time, it will have a great influence on the life of the Yin and Yang rotor, because many of the original causes of mechanical failure are made between the clearance between the bearing and the spindle.
2. Increasing wear and tear
As we all know, as long as the machinery is worn, the wear will be reduced in normal condition because of lubrication, but the wear is slowly increasing for a long time. Take the high end bearing as an example: in the near impossible conditions (such as long term air rotation, sufficient clean of the lubricating fluid, good cooling system enough, and the use of ambient temperature, humidity, etc.), only a few years can be guaranteed. As far as compressor host is concerned, there are other parts wear out besides bearings. If minor wear is not taken correctly, it will easily lead to wear and tear, causing damage and wear of other main components.
3, component deformation
The main compressor is the core compression component of the compressor. Its internal components are in the environment of high temperature and high pressure for a long time, and the high speed operation is added, and the deformation of the parts is inevitable for a long time. At the same time, the cause of deformation and the use of environmental factors, and the air compressor generally used in the environment of the air will have dust and impurities, these tiny solid substances, after entering the machine, when the accumulation of large solid blocks, it may cause the deformation of the Yin and Yang rotor, the gap increases, serious will lead to The host card is dead.
4, part damage
In the main parts of the air compressor, the main parts of the vulnerable parts are: various gaskets, seals, shaft oil seals, etc., especially the shaft oil seal, in a long time in high temperature, high pressure, and high-speed operation of the environment, its service life ratio is greatly shortened. The direct consequence of its damage is the leakage of oil from the compressor. If it fails to be detected in time, it will cause the rotor and bearing of the Yin and yang to burn down due to lack of lubrication.
5. Increase in cost
The cost here refers to the maintenance cost and the electricity cost. As the main engine of the air compressor has not been overhauled for long time, the wear and tear of the components are increased and some of the worn impurities are left in the host cavity, and the life of the lubricating fluid will be shortened. At the same time, because of the impurities, the use time of the oil and gas separator and the oil filtration period is greatly shortened, and the maintenance cost is increased. In the aspect of power cost, the increase of friction and the reduction of compression efficiency will inevitably result in the increase of power cost. In addition, the reduction of gas consumption and reduction of compressed air quality due to compressor main engine will also lead to indirect increase of production cost.
