The rated discharge pressure of air compressors is divided into low pressure (0.7~1.0MPa), medium pressure (1.0 ~ 10MPa), high pressure (10 ~ 100MPa) and ultra-high pressure (above 100MPa). Different pressure ranges can be selected according to different needs. Specifically, the following application-related air compressor pressure information is available:
low-pressure air compressors: Usually used for simpler applications, such as spraying, ballooning and cleaning. Its maximum output gas pressure is generally defined as below 7bar. This kind of air compressor often uses piston type or screw type structure.
Medium and high pressure air compressor: more used for more complex applications, such as electronic components manufacturing and metallurgical processing. Their maximum output gas pressure is in the range of 7bar to 40bar, and they are of screw or turbine type construction.
Ultra-high pressure air compressors: When extremely high pressure requirements are involved, such as gas testing and processing in the aerospace or nuclear industries, ultra-high pressure air boosters are required. The output gas pressure of these devices can exceed 1000bar. They generally use multi-stage pressurization to achieve such high pressures.
In addition to the above classification, there are some special air compressor categories:
two-phase electric compressor: The maximum pressure can be 8~10kg, but usually, 8kg is the maximum pressure set.
Household electric air compressor: Some household 220V electric air compressors can provide a maximum of 10kg of air pressure, corresponding to a pressure of 150Pa.
According to the purpose and structure, the pressure of the air compressor can also be classified as follows:
mini air compressor: the pressure is 1 ~ 5bar, which is often used to provide power to pneumatic tools and valves.
Light air compressor: the pressure is 5 ~ 10bar, widely used in industrial manufacturing processes, such as dust blowing and sand blasting.
Medium-sized air compressor: 10 ~ 20bar pressure, to meet the needs of various factories, mines and construction fields.
This type of air compressor can produce 25 ~ 30bar high pressure, mainly used in large pneumatic equipment and valves.
Therefore, the maximum pressure produced by the air compressor varies significantly depending on the use, type and design. If you need to know exactly the maximum pressure capacity of a specific compressor model, you should check the technical specifications of that model or contact the manufacturer for details.
Vortex air compressor and screw air compressor are two different kinds of compressed air generating equipment, which have significant differences in structure, working principle and application. Structure and working principle: vortex air compressor (also known as scroll air compressor) adopts scroll type
There are many hidden dangers in the operation of the air compressor, which may come from the design of the equipment itself, operating conditions, maintenance conditions and the behavior of the operator. The following is a detailed analysis of the safety hazards of air compressors: 1. equipment design and
The scroll air compressor and screw air compressor are suitable for different scenarios due to differences in structure and design, and the specific selection should be combined with the actual gas demand. Starting from the core characteristics, the following compares the two types of equipment and explains the unique advantages of Granklin water-lubricated single-screw air compressor: vortex air pressure
Equipment with a pressure of 0.1MPa is generally not considered special equipment. According to relevant regulations and standards, special equipment usually refers to equipment that involves life safety and is more dangerous, such as pressure vessels, boilers, elevators, etc. For pressure vessels, in general, when working
When discussing which is better, we need to consider a variety of factors, including the use of demand, maintenance costs, environmental performance and so on. The following is a detailed comparison between the two: oil air compressor working principle: oil air compressor in the working process, run
Oil-free scroll compressors can indeed be used for gas transfer. The oil-free scroll compressor is a kind of positive displacement compressor. Its working principle is to compress through two intermeshing scrolls (a fixed scroll and an eccentric swirling and flat scroll).
In modern industrial production, compressed air is an important power source, and the material selection of its pipeline system is directly related to the safety, reliability and operating efficiency of the system. The water-lubricated screw air compressor products produced by Shanghai Granklin Group, with its unique ring
The pressure of the air compressor usually varies according to its type, specification and usage scenario. The following are some common pressure ranges of air compressors: 1. low-pressure air compressors are classified according to pressure levels: the working pressure is usually 0.7 to 1.2 MPa (trillion
Medium pressure scroll air compressor and screw air compressor have their own unique advantages and application scenarios, which is better depends on the specific gas demand and working environment. Scroll air compressor with its compact
Air compressor maintenance does not necessarily have to be carried out by the manufacturer, but choosing the manufacturer to carry out maintenance does have its advantages. The following is a detailed analysis of this problem: air compressor maintenance definition and content definition: air compressor maintenance refers to the maintenance and maintenance of the air compressor to ensure its
