In the field of air compressors, "ppm" is an abbreviation of "parts per million", meaning "one part per million". When talking about the residual oil content of the air compressor, ppm is used to quantify the oil content in the compressed air. In the field of air compressors, ppm is usually used to express the weight of oil per million parts of air in compressed air.
For example, if the residual oil content of the air compressor is 2ppm, this means that there are 2 parts by weight of oil per 1 million parts by weight of compressed air. This is a very important indicator, especially in applications that require pure compressed air, such as food, medical or precision manufacturing industries. High oil content may affect the production process or product quality in these industries.
In order to reduce the oil content in the compressed air output from the air compressor, various filters and dryers are usually used for treatment. The lower the value of the residual oil content ppm, the higher the purity of the compressed air.
For air compressors, "oil and water" usually refers to the condensed water and possible lubricating oil produced during the compression process. However, the situation is slightly different when discussing the water-lubricated air compressor and oil-free air compressor of Shanghai Grankering Group.
Under normal circumstances, the air compressor lubricating oil is not recommended to be replaced by oil, but it can be replaced in a short period of time in specific low-requirement scenarios, while the high-pressure high-power air compressor is strictly prohibited. The specific analysis is as follows: the reason why substitution is not recommended is the difference in performance requirements: air compressor oil: specially designed for air pressure
空气压缩机的工作压力范围因应用场景、设备类型及行业需求而异，通常以兆帕（MPa）为单位，工程中常简化为“公斤”（1公斤≈0.1MPa）。以下是其核心标准与应用场景的详
The reasons for the high power consumption of the air compressor can be summarized in the following aspects: 1. the improper selection of the capacity is too large: the energy consumption of the air compressor is proportional to its capacity. If an excessive capacity is selected, the air compressor will consume more energy when compressing air. Therefore, in the election
The reason for the loud noise of the air compressor can be attributed to the following points: Air inlet and outlet noise: When the air compressor is running, the air will produce strong airflow noise through the inlet and outlet. This is due to the high speed flow of the gas stream and the pressure change. Specifically, when the air is fast
The oil content of compressed air ≤ 0.01 mg/m & sup3; is not micro-oil, but belongs to the international standard ISO 8573-1 Class 0 (Class 0) standard, which is usually regarded as equivalent to the oil content of oil-free compressed air. The following is a detailed explanation of this conclusion: the 1. State
To ensure that the air compressor does not carry water, the key is to effectively control the moisture content in the compressed air. The following are some recommended measures to achieve this goal: After cooler: Installing an efficient after cooler can significantly reduce the temperature of compressed air, from
In the food industry, the feasibility of using oil compressors depends on a number of factors, including the specific application, air quality requirements, equipment configuration and control of oil contamination. First of all, the food industry has very high requirements for air quality, because any pollution is
Oil-free air compressor and oil-free air compressor have their own advantages and disadvantages, which is better depends on the specific application scenarios and needs. The advantages of the oil air compressor mainly include: higher work efficiency: due to the effect of oil lubrication, the oil air compressor is aging at work
Gas is indeed used in the plating process. The following are several aspects of the gas used in the electroplating process: Protective gas: In the electroplating process, inert gases such as argon are often used as protective gases. Their main function is to prevent the oxidation reaction from affecting the plating
