SSY005978451 Main Pump Upper Cover Plate II Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

SSY005978451 Main Pump Upper Cover Plate II Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY005978451 main pump cover plate II is an important protective component of the wind turbine hydraulic main pump system. It is installed on the upper part of the main pump and is used to cover and protect the main pump cavity, hydraulic pipelines and joint structure. It effectively prevents outdoor wind, sand, rain, salt spray and moisture from entering the pump body, avoiding problems such as dust accumulation and blockage, pipeline corrosion and hydraulic oil deterioration due to moisture, ensuring the clean and stable operation of the hydraulic system. It can directly replace the old, deformed, cracked, rusted and seal-failed original cover plate.
This product is made of high-strength, weather-resistant sheet metal in one piece, resulting in a robust and rigid structure that resists impact and compressive deformation, making it suitable for long-term operation under high-frequency vibration and outdoor wind load conditions. The surface undergoes multiple anti-corrosion, anti-rust, and weather-strengthening treatments, resisting high and low temperature fluctuations, near-shore salt spray corrosion, wind and sand erosion, and UV aging, preventing rusting, cracking, fading, and deformation. The original factory mold ensures precise conformity; the contours, curvature, and mounting hole positions perfectly match the original standard, eliminating the need for cutting, grinding, or modification. It features a seamless, original-position installation with excellent sealing, making it suitable for unit maintenance and replacement as well as bulk orders for complete units.

【Core Technical Parameters】

– Product Model: SSY005978451
– Product Type: Protective cover for wind power main pumps, core component for sealing and protecting the upper part of hydraulic main pumps.
– Compatible Models: Compatible with all Sany onshore and offshore wind turbines, with a dedicated mounting position on the upper part of the hydraulic main pump of the matching unit, allowing direct replacement of the original main pump top cover plate II.
– Core material: High-strength weather-resistant structural plate, one-piece molding process, dense structure to resist deformation, surface anti-corrosion and anti-rust hardening treatment, wear-resistant and anti-aging.
– Operating temperature range: -30℃ to +55℃, wide temperature adaptability, no embrittlement or thermal expansion deformation under high and low temperature environments, stable structure and sealing performance.
– Protective performance: All-round dust and water protection, blocking salt spray and moisture, effectively protecting the main pump pipeline, joints and cavity structure, reducing corrosion, dust accumulation and jamming failures, and also has sound insulation and noise reduction effects.
– Structural characteristics: Integrated reinforced plate structure with balanced rigidity and toughness, resistant to impact and compressive deformation, suitable for long-term high-frequency vibration conditions of the unit.
– Weather resistance: Resistant to wind and sand erosion, moisture oxidation, and salt spray corrosion; resistant to UV aging; will not rust, crack, or deform after long-term outdoor use.
– Sealing characteristics: Compatible with original factory sealing accessories, with minimal gaps, effectively preventing water and dust leakage and ensuring the cleanliness and dryness of the main pump’s internal cavity.
– Structural Specifications: Original factory standard outline dimensions, mounting hole positions and fitting curvature, with precise tolerances, perfectly matching the upper mounting cavity of the main pump.
– Installation method: In-situ screw alignment and fixing, no cutting, grinding, or modification required, simple and efficient disassembly and assembly, facilitating daily maintenance and cleaning of the main pump.
– Adaptable to various operating conditions: Resistant to high-frequency equipment vibration and outdoor wind load impact; will not loosen, fall off, or shift during long-term operation.
– Service life: ≥7 years under normal working conditions, ≥4 years under harsh wind, sand and salt spray conditions, with long-lasting and stable protection and structural performance.

Suitable for complex working conditions such as outdoor vibration of wind power, wind and sand erosion, near-shore salt spray, and alternating temperature differences, this product provides all-round protection for the core components of the main pump with its high rigidity structure, excellent sealing performance and strong weather resistance. It eliminates problems such as dust accumulation and water leakage caused by cover plate deformation and cracking, sealing failure, and pipeline corrosion, ensuring the long-term stable operation of the hydraulic main pump system. It is the preferred original factory part for main pump cover plate replacement, complete machine matching, and bulk stocking.
