In the field of modern industrial automation, pneumatic components are widely used in machinery manufacturing, automobile production, food processing and other industries due to their high efficiency, cleanliness and easy maintenance. However, under different working conditions, the performance of pneumatic components may be affected by many factors, which in turn affects the efficiency and stability of the entire system. Today, let's quickly understand the five key factors that affect the performance of pneumatic components to help you better select and maintain pneumatic equipment.
The power source of the pneumatic system is compressed air, and its quality directly affects the service life and working stability of the components. If the compressed air contains moisture, oil, and solid particles, it may cause problems such as seal damage, valve blockage, and cylinder wear.
Optimization method:
Use a high-efficiency air filter to remove impurities and moisture from the air.
Install a dryer in the pneumatic system to prevent condensation from accumulating, especially in humid environments.
Select a suitable lubricating oil mister to provide appropriate lubrication for pneumatic components when necessary.
Pneumatic components usually need to work within a specific pressure range. For example, standard cylinders are usually between 0.4MPa-0.7MPa. Too high pressure may cause damage to the seal, and too low pressure may lead to insufficient execution force. If the air source pressure is unstable, it may cause slow action, insufficient thrust or malfunction.
Optimization method:
Install a pressure regulating valve to ensure that the air supply pressure is within a stable range.
Install a gas tank at the end of the air source to reduce pressure fluctuations.
Check the air supply system regularly to prevent air pipe aging and leakage.
The working environment temperature of pneumatic components has a direct impact on their sealing materials, lubricants, and elastic components. For example:
Low temperature environment (such as the refrigeration industry) may cause the rubber seal to harden and reduce the sealing effect.
High temperature environment (such as metallurgy and plastic molding industries) may cause the lubricant to evaporate, the seal to age, and shorten the service life.
Optimization method:
Select high and low temperature resistant materials (such as fluororubber and silicone rubber) that are suitable for the temperature range.
In extreme temperature environments, use special pneumatic lubricants to prevent drying and wear.
Add insulation or cooling measures around the pneumatic system to prevent the ambient temperature from directly affecting the components.
Pneumatic systems are usually used to drive mechanical movement, so the load size and changes have a great impact on the life, energy consumption, and movement accuracy of pneumatic components. For example, if the load is too large, the cylinder thrust may be insufficient, resulting in slow movement or failure to reset.
Optimization method:
Select the appropriate cylinder diameter and stroke to ensure that the cylinder thrust is sufficient.
In high-speed and high-load applications, consider using a buffer mechanism or guide device to reduce the impact of cylinder movement.
Combined with the flow characteristics of the solenoid valve, ensure that the air supply can match the load requirements.
Although pneumatic components have a simple structure, after long-term operation, problems such as internal seal wear, valve core jamming, and air pipe aging are inevitable. Lack of maintenance can lead to slow movement, air leakage, reduced efficiency, and even affect the operation of the entire production line.
Optimization method:
Regularly check the seal and lubrication status, and replace them in time if they are worn.
Drain the moisture and impurities in the filter at regular intervals to keep the air source clean.
Clean the cylinder, valves and pipes to prevent dust and oil accumulation.
