Although the permanent magnet variable frequency air compressor has excellent performance in energy efficiency, noise, maintenance cost, etc., there are still many factories and enterprises that choose to use power frequency air compressors. The main reasons include:
low initial purchase cost: Compared with the permanent magnet variable frequency air compressor, the manufacturing cost of the power frequency air compressor is lower, so its price is relatively low. For some enterprises with limited funds or sensitive to the initial investment, the power frequency air compressor is a more economical choice.
Simple maintenance: The structure of the power frequency air compressor is relatively simple, and the maintenance is more convenient. For some companies that do not have a professional maintenance team or lack of senior technical personnel, the power frequency air compressor is easier to manage and maintain.
Usage habits: Many factories and enterprises have been using power frequency air compressors for a long time, and have formed fixed usage habits and maintenance processes. Therefore, in the absence of a strong external push or obvious performance gap, they may be more inclined to continue to use the familiar frequency air compressor.
Application scenario limitation: Although the permanent magnet variable frequency air compressor has advantages in energy saving and efficiency, in some specific application scenarios, the power frequency air compressor may be more suitable. For example, in some occasions where the air pressure is not high or the air compressor running time is not long, the use of power frequency air compressor may be more appropriate.
It should be noted that with the continuous advancement of technology and the improvement of energy saving and environmental protection requirements, the market share of permanent magnet variable frequency air compressors is gradually increasing. In the future, with the further development and popularization of permanent magnet motors and variable frequency control technology, permanent magnet variable frequency air compressors may become the mainstream choice in the air compressor market.
Whether the air compressor room needs to be explosion-proof should be judged according to whether there is flammable gas or dust in the environment where it is located. If the air compressor room is located in the presence of combustible gas (such as gas, liquefied petroleum gas, etc.) or dust (such as metal dust, coal dust, etc.)
The ratio of the electric energy consumed by the air compressor into compressed air is not a fixed value, but is affected by many factors, including the design of the air compressor, the quality of manufacture, the operating state and the efficiency of the use of compressed air. Generally speaking, the electric energy of the air compressor is converted into pressure
The following methods can be used to detect the moisture content of air compressors: 1. condensation method Condensation method is one of the most widely used methods for measuring the moisture content of compressed air. The principle is to use the temperature difference to condense the moisture in the air into liquid water, and then pass the weight
Medical air plays a vital role in medical facilities, mainly reflected in the following aspects: filtration and purification: medical air is strictly filtered and purified, which can effectively remove bacteria, viruses, tiny particles, dust, mold and other pollution in the air
Air compressor output pressure range: The wide adaptability of water-lubricated screw air compressors of Shanghai Granklin Group In industrial production, the output pressure range of air compressors is a crucial parameter, which is directly related to whether the equipment can meet specific process requirements. Shanghai Haige
When the factory chooses the air compressor for the air pressure nitrogen generator, the selection of frequency conversion and power frequency should be combined with the comprehensive evaluation of gas characteristics and operation requirements. The core difference between the two lies in the air supply adjustment mode: the variable frequency air compressor can dynamically adjust the speed according to the actual air consumption to realize on-demand air supply;
The oil-free variable frequency screw air compressor has many advantages, including energy saving, environmental protection, stable operation, low noise, low maintenance cost, and long service life. The following is a specific introduction: energy saving: oil-free frequency conversion screw air compressor adopts advanced frequency conversion technology, which can be based on
The air pressure normally used in the factory is not a fixed value, but is determined according to the specific application scenario and equipment requirements. The following is some common factory air pressure standards related information: standard atmospheric pressure: in industrial production, commonly used standards
The air compressor room of the pharmaceutical factory plays a vital role in the pharmaceutical process, and its main role is reflected in the following aspects: 1. Provide pure compressed air The pharmaceutical factory has extremely high requirements for the purity of the production environment. The air compressor room removes the moisture in the compressed air
Pharmaceutical companies do use air compressors, and this equipment plays an important role in the pharmaceutical production process. The following is a detailed description of the use of air compressors by pharmaceutical companies: 1. to the reasons why pharmaceutical companies use air compressors to provide a stable gas source: in the pharmaceutical production process, it is allowed
