Air compressor national standard mainly involves the following aspects:
1. basic performance requirements
pressure, temperature and flow rate: The national standard of air compressor specifies the performance parameters such as pressure, temperature and flow rate of air compressor to ensure the normal operation and high efficiency of air compressor.
Vibration and noise: The national standard limits the vibration and noise of the air compressor to ensure that it will not cause adverse effects on the surrounding environment and users during use. Specifically, the noise should not be greater than 85dB during normal operation.
2. safety requirements
the mechanical temperature of each part of the compressor should be controlled within the allowable range to prevent the danger caused by over-temperature.
The national standard also puts forward requirements for the safety valve and other safety devices of the air compressor to ensure that the pressure can be released in time under excessive pressure or other abnormal conditions to protect equipment and personal safety.
3. structure and material requirements
the national standard of air compressor also stipulates the structure and materials used in the air compressor, requiring that the structure should be reasonable and firm, and the materials should meet relevant standards to ensure the stability and durability of the air compressor.
4. volumetric efficiency
volumetric efficiency refers to the ratio of the compressor from the inlet end to the exhaust gas with respect to the theoretical volume. The national standard specifies the volumetric efficiency requirements of the air compressor, which is one of the important indicators to measure the performance of the air compressor.
In addition, for ordinary air compressors, the national standard also stipulates that the oil content in the exhaust shall not exceed a certain limit, usually the liquid oil content shall not exceed 5 mg/m & sup3;, and the oil vapor content shall not exceed 0.5 mg/m & sup3;, To ensure the quality of compressed air and the normal operation of the air compressor. For micro-oil air compressors, the oil content in the outlet air shall not be higher than 0.01 mg/m & sup3;, while the oil content of oil-free air compressors is considered to be close to 0.
In general, the national standard for air compressors specifies a series of requirements on air compressor performance, safety, structure and materials, and environmental protection to ensure that the quality, safety and environmental performance of air compressors meet certain standards. These regulations are of great significance for protecting the safety of users, maintaining the normal operation of equipment and protecting the environment.
Air compressors can be divided into two types: oil-free and oil-free. There are some significant differences between them: material difference: oil-free air compressor itself does not contain oily substances, thus avoiding oil pollution to terminal equipment. Air compressor with oil includes
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.
In the production process, the division of pressure ranges is usually based on specific industry standards or engineering practices. For 2.5 atmospheres (or 2.5MPa, because 1 atmosphere is approximately equal to 0.1MPa), we can refer to the pressure classification standard of industrial pipelines to evaluate the pressure to which they belong.
Whether the air compressor tank can continue to be used after more than ten years depends on the comprehensive consideration of many factors. The following is a detailed analysis of this problem: Service life and recommendation: Generally speaking, the service life of the air compressor tank is about 10 years. But
The air compressor itself does not require direct use of water during operation. However, in some particular applications or systems, water may be involved in the operation of the compressor in different ways. First of all, it needs to be clear that common air compressors, such as pistons
The relationship between the working pressure and the discharge pressure of the air compressor is a frequently mentioned problem. In order to make this clear, we must first understand the definition of these two pressures. Working pressure, usually refers to the air compressor in the working process, the system inside
Air compressor is a kind of machinery and equipment widely used in industrial production. Its function is to compress air into high-pressure gas for various needs in industrial production. In the semiconductor industry, air compressors also play a very important role. This article will introduce
Large air compressors are demanded by many industries because of their powerful gas compression capacity and wide range of application scenarios. The following are some typical plants and industries where large air compressors may be used: Typical Plant Type Steel Plant: Use: Oxygen Production in Steel Production
The replacement cycle of the air compressor oil filter will be affected by many factors, including the quality of the oil filter and the use environment of the air compressor. Generally speaking, the service life of the better quality brand oil filter can reach 3000 hours, while the service life of the general quality oil filter may only be
Regarding the setting of air pressure in general production equipment, according to the general specifications in the industrial field and the requirements of equipment operation, the following professional instructions are made on the setting principles and management points of air pressure parameters: 1. the setting benchmark of air pressure parameters The air pressure setting of production equipment shall follow the equipment technology
