What is the normal range of factory pneumatic equipment pressure
The normal pressure range of factory pneumatic equipment needs to be determined based on the specific equipment type and application scenario, but the following general principles are usually followed:
1. Pressure range of common pneumatic equipment
| device type | Working pressure range (MPa) | typical application scenarios |
|---|---|---|
| General pneumatic tools | 0.5-0.8 | Drilling machine, polishing machine, pneumatic screwdriver |
| fine control valve | 0.2-0.5 | Sensors, micro cylinders, medical instruments |
| high-load equipment | 0.7-1.0 | Large cylinders, punching machines, automated transmission lines |
| special equipment | 1.0-1.5 | Certain high-pressure cleaning equipment, special process equipment |
2. Impact of pressure fluctuations
- excessive pressure(> Equipment rating):
- Accelerate seal aging, resulting in air leakage.
- Increase equipment wear and shorten life.
- Energy consumption increases (air compressors need to be loaded more frequently).
- Too low pressure(<Minimum equipment requirements):
- The output force of pneumatic tools decreases and the efficiency is reduced.
- Control system responds slowly or fails.
- May cause production line downtime.
3. Pressure regulation and control
- Pressure reducing valve configuration：
- Install pressure reducing valves at the outlet of the air compressor and the front end of key equipment to ensure that the pressure is stable within the range of equipment requirements.
- Pressure gauge monitoring：
- Install pressure gauges at main air supply pipelines and key equipment, and regularly inspect pressure values.
- Pressure fluctuation treatment：
- instantaneous peak: Pressure fluctuations are buffered by an air tank.
- Continuous low pressure: Check whether the air compressor capacity matches, or clean blocked pipes/filters.
4. Industry standard reference
- ISO 1219-1: Specify the pressure level of the pneumatic system. The common levels are 1 (0.2-0.4 MPa), 3 (0.5-0.7 MPa), and 5 (0.7-1.0 MPa).
- industry norms: Industries such as automobile manufacturing and food processing may have stricter pressure standards.
5. Selection suggestions
- Statistical equipment requirements: List the rated pressure ranges for all pneumatic equipment.
- Determine system pressure: Select the highest pressure that covers 80% of equipment requirements as the system pressure.
- reserve allowance: It is recommended that the system pressure be 10%-15% higher than the maximum equipment requirement.
example: If the pressure requirement of pneumatic equipment in a factory is 0.5-0.8 MPa, the system pressure can be set to 0.8 MPa, and the low pressure equipment can be supplied with air through a pressure reducing valve.
summary: The pressure of pneumatic equipment in the factory needs to be flexibly adjusted according to the equipment type and application scenario. It is usually controlled at 0.5-0.8 MPa to cover most needs, but it needs to be accurately controlled through pressure reducing valves and pressure gauges.
