Products Description
Excavator hydraulic main pump seals usually include various seals, such as mechanical seals, oil seals, O-rings, etc. These seals can be installed in different pump parts, such as the pump body, shaft seal, flange, etc. The materials of hydraulic main pump seals usually include rubber and metal to adapt to different working environments and requirements.
Excavator Hydraulic Main Pump Seals-Ideal Mechanical Seal Solution
1. Structural Features
Multi-layer structure: Excavator hydraulic main pump seals are usually composed of multiple layers of materials, including an elastomer layer, metal support layer, and sealant layer. This structure can effectively improve sealing performance and durability.
High-pressure tolerance: Since the hydraulic main pump works in a high-pressure environment, the seal needs good and high-pressure resistance to prevent hydraulic oil leakage.
Wear resistance: The surface material of the seal is usually made of wear-resistant synthetic rubber or polymer to withstand high frequency and high load operations in the hydraulic system.
Adaptive design: The design of the seal needs to take into account the various working conditions of the excavator hydraulic pump, including high temperature, low temperature, and vibration environments, to ensure its adaptability and stability.
2. Seals Types
Common seal types for excavator hydraulic main pumps include the following:
- Piston Seal:
Mainly located between the plunger and the pump body, used to seal high-pressure oil.
Common materials include rubber, polyurethane, etc.
According to the structure, it can be divided into different shapes such as V-type, U-type, and O-type.
- Shaft Seal:
Located between the pump shaft and the pump body, used to seal the oil circuit of the bearing chamber.
Common materials include nitrile rubber, polytetrafluoroethylene, etc.
According to the structure, it can be divided into mechanical seals, hydraulic seals, etc.
- End Cover Seal:
Located between the main pump end cover and the pump body, used to seal the inner cavity of the pump body.
Common materials include rubber, polyurethane, etc.
According to the installation method, it can be divided into round seals, flat gaskets, etc.
- Valve Block Seal:
Located between the main pump valve block and the pump body, used to seal the valve cavity.
Common materials include rubber, metal, etc.
According to the structure, it can be divided into flat seals, O-rings, etc.
These seals are directly related to the sealing performance and service life of the main pump. When the seals are worn or damaged, it will cause oil leakage, system pressure drop, and other problems, affecting the working stability of the excavator. Therefore, regular inspection and timely replacement of the main pump seals is a very important maintenance work.
