PPM is the abbreviation of the English part per million, which means the number of parts per million or parts per million. It is usually used to express the content of trace substances in the mixture, with weight ratio (PPMw) and volume ratio (PPMv). In the field of air compressors, the reference to an oil content of 3PPM usually means a weight ratio, I .e. 3 parts by weight of oil per million parts of air. Specifically, if the weight of oil contained in 1kg of air is 3 mg, the oil content of the air compressor is 3PPM.
In addition, the oil content of the air compressor may also be affected by other factors, such as compression ratio, temperature, humidity, etc. Therefore, when selecting and using an air compressor, it is necessary to comprehensively consider the influence of these factors on the oil content, and select the appropriate air compressor model and configuration according to actual needs.
In addition, it should be noted that in practical applications, the lower the oil content of the air compressor, the better, because too high oil content will adversely affect the quality of the compressed air and the operational stability of the equipment. Therefore, some high-end air compressor products will adopt oil-free or low-oil design to meet the needs of occasions with high requirements for compressed air quality.
The time to change the oil of a new air compressor depends mainly on the type of oil used and the manufacturer's recommendations. Generally speaking, the newly purchased air compressor should be replaced with new oil after 500 hours of operation for the first time. Subsequently, the replacement cycle varies depending on the oil type: mineral oil
The air compressor shows that the host imbalance may be caused by the following reasons: host installation problem: the host may not be aligned during installation, that is, the vertical and horizontal installation planes are not found, resulting in imbalance when the host is running. Foundation or base
The level of compressed air used in food processing is very strict to ensure the safety and hygiene of food. These requirements usually follow relevant international or national standards, such as ISO 8573-1, and cover many aspects, including purity, microbial content, particulate matter
In the scenario where multiple devices share an air compressor, it is necessary to select an air compressor with appropriate power by calculating the total air consumption and considering factors such as margin, pressure matching, equipment characteristics and air tank buffer. The specific calculation steps are as follows: 1. calculate the total gas consumption of a single device.
Suggestions for air compressor selection in food enterprises: oil compressors are at risk, and oil-free technology is more in line with safety standards. In the food production process, compressed air is used as a key power source and process medium, and its quality directly affects product safety and compliance. According to industry practice
When discussing whether the air compressor condensate can be directly discharged outdoors, we need to comprehensively consider environmental protection regulations, equipment characteristics, and various factors in actual operation. Taking the water-lubricated air compressor products produced by Shanghai Glanklin Group as the core, we can
The air moisture standard after air compressor drying treatment will vary according to different applications and industries. Generally speaking, the moisture content of the compressed air after drying treatment should be very low to ensure the normal operation of the system and prevent moisture from the equipment and process.
When it comes to the maintenance of air compressors, many people first think of the replacement of oil. However, for the water-lubricated screw air compressor produced by Shanghai Granklin Group, this question has a different answer. Water lubricated screw air compressor, as a
There are many hidden dangers in the operation of the air compressor, which may come from the design of the equipment itself, operating conditions, maintenance conditions and the behavior of the operator. The following is a detailed analysis of the safety hazards of air compressors: 1. equipment design and
Answer: The difference between a compressor and an air compressor is mainly manifested in the following aspects: Different compression media: An air compressor is a machine that compresses and stores air, and the compression medium is air. And the compressor wide
