The range of air pressure used in general factories will vary according to different applications and equipment. However, based on publicly available information, we can summarize some common situations:
common types and ranges of air pressure in 1. factories
common air pressure in the factory mainly includes compressed air, hydraulic oil and nitrogen. The approximate range of these air pressures is as follows:
compressed air:
compressed air is a common energy source in factories and is widely used in the fields of power transmission, control and mechanical operation.
Common compressed air pressure ranges from 0.5 megapascals (MPa) to about 1.0MPa. However, in certain industries, such as papermaking, printing, glass manufacturing, etc., the air pressure requirements are higher, and high-pressure compressed air above 2.0MPa may be required.
Hydraulic oil:
hydraulic oil is mainly used to drive various hydraulic equipment, such as hydraulic lifts, hydraulic punches, etc.
The pressure range of hydraulic oil is related to the use scenario, generally between 3MPa and 10MPa. If high-pressure hydraulic oil is required, the air pressure can reach more than 100MPa, but this is rare.
Nitrogen:
nitrogen is widely used in processes and equipment under high pressure and low temperature environment, such as violent film pressing equipment.
The pressure range of nitrogen is very large, ranging from 0.1MPa to 100MPa. The specific pressure used should be determined according to the specific application scenario and equipment requirements.
General conditions of 2. plant supply pressure
for the factory air supply system, especially the pneumatic transmission system, the air supply pressure also has certain standards:
air supply pressure of main pipeline: generally not less than 0.7MPa to ensure the normal operation of pneumatic equipment.
Gas point pressure: usually adjusted to 0.4~0.5MPa to meet the needs of different pneumatic tools and equipment.
In addition, some factories may make specific adjustments to the gas supply pressure according to their own production process and equipment requirements. For example, if the air pressure of the equipment is 600kPa (I. e., 0.6MPa), the selected pressure of the air source may be set to a slightly higher pressure, such as 750kPa (I. e., 0.75MPa), to ensure stable air supply.
3. Summary
to sum up, the air pressure range used in general factories is not fixed, but is determined according to specific application scenarios and equipment requirements. Common compressed air pressures range from about 0.5MPa to 1.0MPa, but higher pressures may be required in certain industries. For hydraulic oil and nitrogen, the pressure range is more extensive, ranging from a few atmospheres to hundreds of atmospheres. Therefore, when designing and selecting the factory gas supply system, it is necessary to comprehensively consider and reasonably set according to the actual situation.
In the choice of air compressor, frequency and frequency conversion have their own advantages, the specific choice depends on the actual use of conditions, budget and working environment and other factors. The following is a detailed comparison of the main advantages and disadvantages of the two: Power frequency air compressor Advantages: Simple structure: Control system of power frequency air compressor
To calculate the air consumption of each station of the air compressor, it is necessary to consider a number of factors and adopt a certain calculation method. The following are some commonly used methods and steps: 1. to determine the basic parameters Working pressure: the pressure value reached when the air compressor outputs gas. Flow: units
The main differences between the cold dryer and the suction dryer are reflected in the following aspects: working principle: the cold dryer achieves the purpose of water removal by reducing the temperature of the compressed air, while the suction dryer uses the principle of pressure swing adsorption to remove the saturated compressed air from the upstream
In industrial production, the quality of compressed air directly affects the final quality of the product, in which the water content of the air is one of the important indicators to measure the quality of compressed air. Shanghai granklin group production of water-lubricated screw air compressor, combined with efficient cold dryer system
shanghai screw air compressor manufacturer in shanghai, there are a number of production of screw air compressor manufacturers, including shanghai granklin (group) co., ltd. The following is a detailed introduction to the company: Shanghai Granklin (Group) Co., Ltd. Products
Permanent magnet frequency conversion screw air compressor is to save electricity and stabilize air supply. Water lubricated air compressor makes it better to use in scenes with high cleanliness requirements.
In modern industrial production, compressed air is an indispensable energy source in various production equipment and tools. In order to meet the demand for high-quality and efficient air, the oil-free screw air compressor launched by Shanghai Granklin Group has become an outstanding representative in the industry. That
Q: scroll type and screw type which is the most advanced? A: scroll type and screw type air compressor have their own advantages and scope of application, can not simply judge which is more advanced. The principle of scroll air compressor determines that it can only be used in small models (15KW and below)
The difference between an oil air compressor and an oil-free air compressor is that the working method is different and the final discharge gas is different. Oil-free air compressor: oil-free air compressor does not contain lubricating oil in this working process and is lubricated with water.
The application of compressed air in the fermentation industry is very extensive and important, mainly reflected in the following aspects: Power drive: The production process of the fermentation industry requires a steam turbine to drive the air compressor to provide the compressed air required for the fermentation equipment.
