Return oil pipeline Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core hydraulic component of Sany Construction Machinery, the Sany return oil pipeline strictly adheres to the design principles of return oil, ensuring uninterrupted connection to the oil tank, preventing oil splashing and air bubbles, avoiding pump cavitation and air intake, and providing a safe return path for the hydraulic system. It is widely compatible with the entire range of Sany excavators, including the SY55, SY225, and SY465, as well as tank trucks, perfectly matching original factory dimensions. It can be directly replaced without modification, improving maintenance efficiency and reducing equipment downtime losses.
The product uses high-specification materials and precision processes. The main body of the pipeline is a corrosion-resistant and anti-aging seamless steel pipe. The joint adopts an integrated, peel-free, embossed gourd-type structure with steel stamp markings. It has excellent sealing to prevent leakage, and is anti-pulse and anti-wear. It is suitable for complex working environments, is not easy to deform and crack, extends service life and reduces operation and maintenance costs.

Core technical parameters:

– Compatible models: Sany SY55/SY60/SY75 and other full series excavators and Sany tank trucks and other hydraulic equipment.
– Operating pressure: ≤35MPa, suitable for low-pressure return requirements, protecting the shaft seal from damage.
– Operating flow rate: 10-160L/min, adaptable to different equipment flow requirements as needed.
– Pipe diameter: φ10mm-φ38mm (customizable), commonly used are φ16mm, φ25mm, and φ38mm, conforming to flow velocity standards (1.7-4.5m/s).
– Material specifications: 20# seamless steel pipe body, high-quality carbon steel joints, galvanized for rust prevention.
– Sealing standard: Nitrile rubber seal, sealing pressure ≥40MPa, suitable for environments from -40℃ to 120℃.
– Installation method: Flange/threaded connection, consistent with original interface (some G1 specifications), easy to install.
– Execution Standard: Complies with GB/T 3683-2011 and SANY original factory specifications, and has passed pressure and sealing tests.

Compared to ordinary pipelines, Sany’s drain and return oil pipelines are designed to meet original factory standards, with optimized structural design to ensure smooth drain and return of oil. They centrally guide leaked oil back to the oil tank and remove heat, reducing system temperature rise and preventing failures such as shaft seal damage and housing cracking. This protects the stability of the hydraulic system and improves equipment efficiency and lifespan.
We specialize in supplying Sany construction machinery parts. All our drain and return oil lines undergo rigorous quality inspection, meet original factory standards, and are highly compatible. We support both bulk customization and in-stock supply, and provide comprehensive after-sales service. Choosing Sany drain and return oil lines saves you time, effort, and money, ensuring safe and secure construction operations.
