What is the atmospheric pressure used by general industrial products
What is the atmospheric pressure used in general industrial products?
In the industrial field, product design and testing are usually based onstandard atmospheric pressureis the benchmark, and its value is101325 Pascal (Pa), approximately equal to0.101325 MPa (MPa)or1.01325 Bar。This parameter is based on the international standard atmospheric pressure definition and is widely used in scientific calculations and industrial production to ensure the unity of pressure values in different scenarios.
Pressure range in industrial applications
Although standard atmospheric pressure is a common benchmark, the atmospheric pressure used for specific industrial products needs to be adjusted based on equipment characteristics and process requirements. Common scenarios are as follows:
- automatic production line: The compressed air pressure driving pneumatic tools (such as robots, spraying equipment) is usually set to0.6~0.8 MPato ensure stable operation of equipment.
- precision manufacturing: In pressure-sensitive processes such as electronic chip manufacturing, the air pressure needs to be accurately controlled at0.4~0.6 MPaAvoid high-pressure damage to precision parts.
- Special process requirements：
- high-pressure forming: Certain processes (such as metal forging, composite pressing) may require10~100 MPahigh-pressure environment.
- chemical reaction: Depending on the reaction conditions, the pressure range can range from near atmospheric pressure to tens of megapascals.
- industry differences：
- Food/Medicine: Except for air pressure range (usually0.5~0.8 MPaIn addition, there are strict standards for the cleanliness of compressed air (such as oil content and microbial content).
- aerospace: Some tests need to simulate a high-altitude and low-pressure environment, and the pressure may be lower than standard atmospheric pressure.
Enterprise application suggestions
- demand matching: Clarify the gas pressure range based on equipment parameters, process accuracy and industry standards to avoid blindly using standard values.
- system design: Configure pressure regulating valves, air tanks and other equipment to ensure that the air supply pressure is stable within the target range.
- monitoring and maintenance: Monitor the pressure of the pipe network in real time through pressure sensors, regularly verify the accuracy of equipment, and prevent pressure fluctuations from affecting product quality.
conclusion
The atmospheric pressure used in general industrial products is based on101325 Pa（0.101325 MPa）is the benchmark, but in practical applications it needs to be adjusted to an appropriate range according to equipment, process and industry characteristics. Enterprises should ensure that pressure parameters are highly matched with production needs through scientific design, precise regulation and regular maintenance, thereby ensuring product quality and production efficiency.
