In the era of energy saving for all, people are very concerned about the energy efficiency of air compressors. There are more and more primary energy efficiency air compressors in the market, which is indeed a good phenomenon for the benefit of the country and the people. But more people pay attention to the energy efficiency of new machine, but ignore the market energy efficiency after air compressor. The market energy saving of air compressor is a new field, which is still in the exploration stage. However, it is certain that if an air compressor can be maintained reasonably, the energy efficiency will be better expanded. With the market becoming more and more mature, the market energy saving after air compressor is likely to be the next outlet in the near future.
After many years of working in the whole machine and aftermarket of air compressor, the author has some personal opinions and experience, and tries to discuss with you. In order to facilitate the reading of many novice friends, this paper describes in a simple and understandable way, not involving deep technical knowledge.
It is believed that almost all air compressor agents and friends will often encounter such a difficult problem: some air compressor users do not want to maintain on time, want to delay maintenance for hundreds, 1000 hours or more. In this case, it is estimated that the most common reason we have talked with the user is how much potential harm the delayed maintenance will bring to the air pressure opportunity, which can also persuade some of the users to maintain on time. If you meet users who really don't make sense, you can only say "don't blame me if something goes wrong in the future". This should be dialogue technology, probably is the version that most air compressor agents often use.
In this way of persuading users, I think that the main reason why customers want to delay maintenance is that they haven't found the core of the problem? Apart from the objective factors that the user can't stop the machine for maintenance due to the busy production, the user wants to delay the maintenance just to save money. Since the user wants to save money, you talk about a lot of potential harm of delayed maintenance to the air compressor, which is not particularly targeted, and the effect will definitely be greatly reduced; moreover, even if the maintenance is delayed for hundreds or 1000 hours, the air compressor will not have too big problem in a short period of time, and the user can't see the harm brought by delayed maintenance, so the psychology of naturally wanting to save money has the upper hand, leading to the saying of taking it Timely maintenance is half the work.
Since users want to save money, we should follow the idea of saving money to persuade users. When you maintain the machine, you don't know if you pay attention to the overcurrent. Generally, the current difference before and after maintenance is 5-15% (7-10% is the mainstream). This means that the electricity cost wasted by delaying 500 hours of maintenance is enough for one maintenance, and the longer the delay time is, the greater the current difference will be. This is because the air compressor runs in a round of maintenance cycle, and the oil separation surface has absorbed a lot of dust and carbon. If the maintenance is delayed, the dust and carbon on the oil separation surface will be more and more;
In addition, after a round of maintenance cycle operation, the aging speed of the lubricating oil will be accelerated, the rate of carbon deposition will be geometrically doubled, and the delayed maintenance will speed up the improvement of the current; then, after a round of maintenance cycle operation, if the air filter is not replaced in time, the suction resistance will increase, which will also reduce the energy efficiency of the air compressor.
