Basically, according to each air compressor factory has a standard for its own air compressor, it is best to look at the instructions! Some manufacturers also have 2000 hours of oil and 4000 hours of oil.
Some start from the sale to the customer, the first insurance time and the later half a year or once a year.
Which is first come, first change
1. It is best to look at the oil level mirror to see that the quality of the oil is dark. If the air compressor is not running and there is no internal pressure, you can put the oil out a little bit and touch it with your fingers to smell it. If there is burnt smell or water, you can basically change the oil.
(Of course, if there is a burning smell, find the manufacturer in time. It doesn't matter if there is a small amount of water. It will evaporate into the air with the high temperature. Either lengthen the unloading time or ask the manufacturer. After all, the novice is not clear about the concept of "how much")
2. The oil is transparent or milky yellow when it is not turned on (Shouli is green). This can be compared when it is turned on or when there is unopened oil around it.
3. If you really can't, ask the person who sold the machine to you. After all, you can't just sell it and repair it.
Oil-free air compressor supplier which is good? Choose air compressor suppliers, not only than price, but also depends on product quality and after-sales. The purchase of mechanical products, manufacturers as air compressor suppliers, is the best. Many people are not very familiar with how to purchase high-quality oil-free air compressors. Oil-free screw air compressors technical experts pointed out that customers should choose formal and powerful manufacturers. Let's look at the analysis of well-known technical experts in related fields.
View detailsAir compressor, full name air compressor (English: air compressor) is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is a pressure generator for compressed air. Is one of the most commonly used in industrial and mining enterprises to provide air power equipment. Usually, the air compressor is divided into screw type air compressor, piston type air compressor and so on.
According to market conditions, most manufacturing industries choose air compressors. For example, oil-free air compressors are generally used in the food industry and the pharmaceutical industry. The laser industry uses more medium pressure. Textile and chemical fiber industry uses more low pressure. For high-pressure testing of products, bottle blowing
On the whole, it is more cost-effective to purchase water-lubricated air compressors. After all, water-lubricated air compressors are better than traditional oil-injected air compressors in terms of maintenance and gas.
Shenzhen Air Compressor Equipment Factory and Shenzhen Screw Air Compressor Factory have a pressure gauge in front of the filter element at the time of ordinary screw air pressure. Shenzhen Air Compressor Equipment Factory stops changing the oil core when the pressure difference between the pressure gauge in front of the filter element and the air supply pressure gauge reaches 0.08MPa. When the oil core is damaged, it will be found that the oil consumption of the air compressor is very serious, and there will be a small amount of oil in the gas storage tank and pipeline in Shenzhen Air Compressor Equipment Factory. In severe cases, discharge the air compressor oil at the discharge time of the air tank drain valve.
As a completely market-oriented industry, China's screw air compressor enterprises have experienced several rounds of ups and downs, some star enterprises "flash in the pan" out of the market.
General oil-free air compressor is roughly divided into: water lubrication type, dry grinding type, reciprocating type, these three. 1. Water-lubricated air compressor Because the oil-free air compressor uses stainless steel and porcelain composite motor rotor, its driving force rolling bearing is completely oil-free.
At present, the price of air compressors on the market is relatively transparent and there is no standard. The same technology, technology and quality of ordinary power frequency air compressor, all brands are similar, foreign brands of air compressor prices are higher. The price of the real energy-saving air compressor will be higher than that of the ordinary air compressor, which is determined by technology, quality and energy-saving effect. Granklin air compressor saves more than 30% of electricity on average, so the price will be higher, but this can be ignored, because the energy-saving part in use will soon make up for this. So sometimes high prices are an affirmation of true energy-saving technologies.
View detailsGranklin water-lubricated single screw air compressor is an oil-free air compressor series, which uses water as the lubricating medium to fundamentally solve the problem of environmental pollution caused by lubricating oil. Compared with other oil-free air compressors, it has a simple and compact structure; low speed
The water lubricated oil-free air compressor uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil. Thus, 100% oil-free clean compressed air is provided. Product features: 1. High efficiency, high reliability, 100% pure oil-free
