The ppm of air oil content represents the trace concentration of oil in the air, I .e. the amount of oil per million parts of air. Ppm is the abbreviation of English part per million, which means one part per million. Specifically, if the oil content of air is X ppm, it means that there are X parts of oil per million parts of air.
This concentration expression method is often used to describe the content of trace substances in the air, which is of great significance for the monitoring and control of air quality. In the industrial environment, especially involving oil and gas, chemical and other industries, the monitoring of air oil content is very necessary to ensure the safety of the working environment and the normal operation of the equipment.
It should be noted that, ppm may represent either a weight ratio or a volume ratio, which should be specifically determined according to a context and an application scenario. In the case of equipment such as an air compressor, the term "ppm" generally refers to a weight ratio.
In general, understanding and monitoring the ppm oil content in the air is of great significance to ensure industrial production and environmental safety.
Answer: There are two kinds of industrial grade screw air compressor, oil-free air compressor, oil-free air compressor. Whether it is durable or not has its own opinions. The maintenance of the oil-free air compressor is still very durable according to the requirements of the manufacturer's guidance.
Oil-free air compressors can be divided into five categories according to lubrication methods and working principles, and their technical characteristics and application scenarios are significantly different. The following is the specific classification and analysis: 1. water lubricated oil-free air compressor principle: pure water as the lubricating medium, through the screw and star wheel rotating pressure
Chemical plant compressor room, this is really an important and mysterious place. It is like the heart of a chemical plant, beating silently, providing a steady stream of power for the entire chemical plant. Walking into the compressor room, you will be attracted by the booming machines.
In the cast iron process, compressed air is widely used in many key links, and its role covers cleaning, power drive and process control. Granklin water-lubricated single-screw air compressor can effectively meet the needs of cast iron production by virtue of its oil-free cleaning and stable pressure output.
The core difference between medical air compressor and industrial air compressor lies in the different requirements for the cleanliness, stability and safety of compressed air. Granklin water-lubricated screw air compressor can meet the needs of medical and industrial at the same time by virtue of oil-free clean gas supply and stable pressure output characteristics.
The air compressor does not pump air (or called "unable to pump air", "insufficient pressure", etc.) may be caused by a variety of reasons. The following are some common causes and their corresponding solutions: 1. electrical problems Power lines or power switches
Air compressor, referred to as air compressor, has a wide range of applications and important role in the industrial field. The following are the main uses of air compressors in industry: 1. power supply Air compressors are the power source for many industrial pneumatic tools and equipment. It compresses air
Requirements for solid particle content of compressed air vary according to application fields and specific scenes. International standard ISO 8573-1 and domestic standard GB/T 13277.4 both provide detailed classification and measurement methods. The following are specific instructions: 1. international standard: ISO 8573-1ISO
The air compressor outlet pressure setting range usually varies according to the use scenario and demand. The following are some common air compressor outlet pressure setting range and professional terms explanation: general industrial use: outlet pressure setting range is usually 6 ~ 8b
Vibration failure phenomenon of air compressor The vibration generated during the operation of screw air compressor is very small, and the vibration will increase or exceed the standard under some special circumstances. Cause analysis of air compressor vibration 1. Large deviation of wheel center 2. Loose bottom angle such as bolts
