The types of air compressors can be classified from multiple dimensions. The following are some of the main classification methods and corresponding types:
classification by working principle:
volume type: By changing the volume of the working chamber to compress gas, including piston type, screw type (such as twin screw air compressor), scroll type, etc.
Power type (or turbine type): through the high-speed rotating impeller to make the gas speed, and then expand the deceleration, the kinetic energy into pressure energy, such as centrifugal air compressor.
Thermal type: Compressing gas through thermal energy conversion, this type is rare in practical applications.
Classified by lubrication method:
oil compressor: the use of lubricating oil to lubricate and cool the compression process.
Oil-free air compressor: avoid the use of lubricating oil to ensure the purity of compressed air, suitable for occasions with high air quality requirements.
By performance:
low noise air compressor: design pay attention to reduce the running noise.
Variable frequency air compressor: The operating frequency can be adjusted according to the demand to achieve energy saving.
Explosion-proof air compressor: suitable for flammable and explosive environment, with higher safety.
Classification by purpose:
power air compressor: mainly used to provide compressed air, conveying gas or increase gas volume.
Air compressor for refrigeration: used in refrigeration systems, such as refrigerators, air conditioners, etc.
Ventilation with air compressor: used for industrial and mining enterprises or civil buildings ventilation.
Special air compressor: air compressor for specific purposes such as sandblasting machine and injection molding machine.
Classification by form:
fixed air compressor: installed in a fixed position, not movable.
Closed air compressor: the whole machine is closed to reduce environmental pollution and noise.
Mobile air compressor: easy to move to different work locations.
In summary, there are many types of air compressors, and the selection of the appropriate air compressor needs to be determined according to the specific application scenario, work requirements and environmental conditions.
As an indispensable equipment in modern industry, the price of oil-free air compressor has always been the focus of many enterprises. Among many brands, the water-lubricated air compressor produced by Shanghai Granklin Group is characterized by its unique oil-free design, excellent performance and extensive
The air pressure standards in the filling room of the production plant are as follows: 1. core standards: the pressure difference between the clean area and the non-clean area is ≥ 10 Pa ska (Pa) According to Article 48 of China's current Good Manufacturing Practice (GMP) and GB 50457-2019 "Pharmaceutical Industry Cleaning"
The maximum air pressure of the screw air compressor mainly depends on its design and manufacturing standards. At present, the air pressure of the screw machine can reach up to 4.0MPa. However, please note that different brands and models may have different maximum air pressures. In addition, according to the screw type air compressor
The air compressor can blow continuously, but it needs to be comprehensively judged according to the model, load capacity, heat dissipation design and maintenance status, and it needs to follow specific operating specifications to ensure equipment safety and stable performance. The following is a detailed analysis of the continuous blowing capacity of the air compressor: 1. air compressor
Scroll compressors and screw compressors have their own advantages and disadvantages, and the choice of which is better depends on the specific application needs and scenarios. Scroll compressor: Advantages: compact structure, stable operation, low noise, high energy efficiency, and can still maintain a relatively high level of partial load
The demand for compressed gas in semiconductor factories is characterized by high purity, multi-category, stable supply and strict quality control. The specific requirements are as follows: 1. Core requirements: high purity and high purity requirements for multi-category gases Semiconductor manufacturing requires extremely high gas purity and is usually
In the medical field, compressed air, as an important auxiliary tool, plays an irreplaceable role. It is not only directly related to the normal operation of medical equipment, but also has a profound impact on the treatment effect and life safety of patients. Produced by Shanghai Granklin Group
Generally, the air pressure of compressed air will be determined according to the specific application requirements and equipment specifications. The following are the air pressure ranges of compressed air in some common scenarios: routine applications: in routine applications, the pressure of compressed air is usually between 0.4MPa and 1.0MPa
Hospital air compressors play a vital role in medical facilities. It is mainly used to provide stable, clean, dry and oil-free compressed air to meet the needs of medical equipment, operating rooms, wards and other scenarios. The following is the hospital air compressor
The air output of the air compressor, that is, its exhaust volume, is an important indicator to measure the performance of the air compressor. Specifically, it represents the volume of compressed air that the air compressor can produce per unit time. This value is usually clearly marked in the product manual of the air compressor.
