Types of Hydraulic Piston Oil Seals
1. Leak Prevention One of the primary functions of hydraulic shaft seals is to prevent leaks. Hydraulic fluids can be expensive and environmentally hazardous, making containment crucial. Effective sealing not only saves costs but also protects the environment and enhances safety.
Regular inspection and maintenance of cylinder gland seals are vital. Over time, seals can wear out due to friction, temperature changes, and exposure to harsh environments. Signs of wear may include visible cracks, swelling, or a decrease in sealing performance. Implementing a proactive maintenance schedule can help identify and replace worn seals before they lead to significant issues.
Preventive Measures
The design of the lip is crucial; its profile allows it to make optimal contact with the shaft, creating a seal that can accommodate the shaft's rotation. Some rotary lip seals also include a dust lip or exclusion barrier, which helps protect the primary sealing lip from contaminants such as dirt and debris.
- O-Rings These are circular seals that create a tight fit between two surfaces, preventing fluid leaks. They are usually made of durable materials such as nitrile rubber or polyurethane.
