Why Do Construction Machinery Need to Install Air Permeable Vent Plugs - Wuxi Sinceriend New Material Technology Co., Ltd.

Construction Machinery & Vent Plugs

Construction machinery needs to install air permeable vent plugs due to its harsh working conditions and special operational characteristics. These components play a key role in protecting equipment performance and extending service life in challenging environments.

Harsh Operating Environment

Most construction machinery operates in open-air environments with heavy dust, strong vibration and frequent temperature changes.
Internal pressure balance and impurity prevention become critical in these challenging conditions.
Core components like hydraulic systems, gearboxes and fuel tanks face extreme environmental stresses.
Air permeable vent plugs provide essential protection against these environmental factors.

Thermal Pressure Management

During operation, core components generate significant heat from continuous running.
Temperature fluctuations cause internal air expansion and contraction, leading to pressure fluctuations.
Excessive positive pressure may damage seals and cause oil leakage.
Negative pressure may suck external air and impurities into the system, affecting precision parts.

Pressure Balance Solution

Air permeable vent plugs effectively solve pressure problems by balancing internal and external pressure in real time.
They release excess positive pressure and supplement air appropriately when negative pressure occurs.
This prevents seal damage and oil leakage caused by pressure imbalances.
The breathable and filtering structure blocks dust, sand and moisture from entering equipment.

Vibration & Contamination Protection

Construction machinery often faces strong vibration during operation, which may loosen components.
Vent plugs with stable structural performance maintain effective protection even under vibration.
They ensure that hydraulic oil, gear oil and other lubricants stay clean and free from contaminants.
This reduces wear and tear of internal parts and lowers failure rates.

Air permeable vent plugs provide dual protection of pressure balance and impurity prevention for construction machinery, adapting to its harsh working environment. They are essential components to ensure stable operation, reduce maintenance costs and extend the service life of construction machinery, preventing unexpected shutdowns during critical construction operations.
