The difference between fixed screw air compressor and rotary air compressor can be summarized from the following aspects:
working principle:
fixed screw air compressor: Using the mutual meshing of the yin and yang rotors to continuously reduce the volume between the teeth and continuously increase the pressure, thereby continuously generating compressed air. It belongs to a kind of positive displacement compressor.
Rotary air compressor: through the internal rotor in the rotation of compressed air. It usually uses a water circulation system or an oil cooler as a medium, and the structure is relatively simple.
Structural features:
fixed screw air compressor: the whole machine is reliable, flexible and adaptable. It usually adopts a fully enclosed structure, and the cold and hot flows are separated without interfering with each other. It has the characteristics of low noise, small vibration and no need to install foundation.
Rotary air compressor: Due to its working principle, the structure is relatively simple, the maintenance is convenient, and it can work continuously.
Application areas:
fixed screw air compressor: especially suitable for centralized gas supply places with large gas volume, such as large factories or applications requiring continuous and stable gas supply.
Rotary air compressor: widely used in a variety of occasions requiring compressed air, especially the need for continuous work environment.
Performance characteristics:
fixed screw air compressor: high reliability, long life, low maintenance and so on. Its exhaust volume is hardly affected by the exhaust pressure, and it can maintain high efficiency in a wide range.
Rotary air compressor: It usually has the advantages of simple structure, few wearing parts, stable operation, low vibration, and stable exhaust.
In summary, there are significant differences between the fixed screw air compressor and the rotary air compressor in terms of working principle, structural characteristics, application fields and performance characteristics. Which type of air compressor to choose depends on the specific application requirements and working environment.

Whether the air compressor can be placed in the chemical workshop needs to be comprehensively evaluated in combination with the environmental characteristics of the workshop, equipment protection level and safety specifications. The specific analysis is as follows: Analysis of the environmental characteristics of the 1. chemical workshop Corrosive medium risk The workshop may have acid gas (such as hydrogen chloride
The selection of air compressor is directly related to the production efficiency, energy consumption cost and equipment life. Reasonable matching of air consumption and model parameters can avoid the dilemma of "big horse-drawn cart" or "small horse-drawn cart. The following from the gas consumption
As an important equipment in the industrial field, the quality of the screw air compressor is directly related to the production efficiency and the service life of the equipment. Among many brands, the water-lubricated screw air compressor produced by Shanghai Granklin Group stands out for its excellent quality and performance.
Common oil-free air compressor applications 1, gold plating, copper plating industry applications. In the cleaning process of electroplating, it is necessary to use a compressor to remove water from the surface of the object, and the use of an oil-free air compressor can keep the plating smooth. 2. Medical treatment
Permanent magnet air compressor is a kind of air compressor driven by permanent magnet motor, which has the advantages of high efficiency, energy saving and stability. In the market, there are many brands that provide permanent magnet air compressor products, and each brand has its own characteristics and advantages. For the Shanghai Granklin set
Screw air compressors are generally not recommended for frequent start-up. Frequent start-up may cause additional burden and wear on the electrical system, motor and mechanical parts of the air compressor, shortening its service life. In addition, the current impact at startup may also stabilize the grid.
Yes, the greater the power of the air compressor, the greater the displacement is usually. This is because in a certain pressure range, there is a positive correlation between the power of the air compressor and its displacement. Power is a measure of the energy required for air compressor operation, which is directly related to the air compressor motor
In general, air compressors are designed to maintain a specific pressure range to ensure that they can meet the needs of various application scenarios. Generally speaking, the pressure of the conventional air compressor is maintained at a certain level, which is
The shutdown sequence of the air compressor and the cold dryer shall be: close the air compressor first, and then close the cold dryer after the system pressure is released. The specific steps and reasons are as follows: Close the air compressor 1. to the shutdown sequence and steps: Press the air compressor stop button, and the equipment will gradually stop.
The industrial standard air pressure is usually measured on a standard atmospheric pressure basis. The standard atmospheric pressure is specified in the resolution statement of the 10th International Congress of Metrology in 1954, and its value is 101.325kPa. For a more intuitive comparison with other barometric units, we can
