SSY008119457 Hydraulic oil tank assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The SSY008119457 is specifically designed for the SY1250H mining excavator, a model with high operating loads and high hydraulic pressures, requiring stringent oil storage and purification. It integrates core features such as high-strength corrosion-resistant substrate, precision welding technology, efficient sedimentation filtration, and leak-proof sealing, conforming to national and industry standards such as JB/T 7938-2010, and is compatible with core components such as the SSY009114936 cooling pipes. Suitable for open-pit coal mines and metal mines, it prevents hydraulic component failure due to oil contamination and high-temperature overload, making it a crucial original equipment manufacturer (OEM) part for ensuring continuous operation in mines.

Core technical parameters

Model: SSY008119457
Main body material: Thickened Q235 carbon steel (heavy-duty version), 304 stainless steel (corrosion-resistant version) – both materials are available.
Operating temperature: -30℃ to 160℃
Core operating parameters: nominal volume 200-300L (customizable), conforming to JB/T 7938-2010 standard [4][2]; wall thickness 8-12mm, dimensional tolerance ±0.03mm, inner wall roughness Ra≤1.6μm; working pressure 0.3-0.8MPa, no leakage; oil cleanliness reaches NAS 8 level, equipped with level gauge and alarm device, service life ≥8000 working hours.
Structural Design: Modular integrated molding, laser cutting, bending, and full welding processing, with full welds and no missing welds; built-in layered sedimentation structure, equipped with oil filling, oil return, oil outlet, and drain outlet, precisely matched with SSY009114936 cooling pipes; top is equipped with a ventilator, bottom is sloping for easy drainage, key parts have reinforcing ribs, and it is vibration resistant and deformation resistant.
Shape and size: Rectangular or irregular shape (customized according to the whole machine), regular shape, size adapted to the installation space of SY1250H hydraulic system, length × width × height reference 880×630×450mm to 980×630×500mm, mounting hole position accuracy ±0.05mm, can be directly replaced by the original factory, and matches the size of sealing gaskets, washers and cooling pipes.
Surface treatment: Carbon steel models are treated with pickling and phosphating + high-temperature baking paint, while stainless steel models are treated with passivation + polishing. They are resistant to salt spray for ≥600 hours, preventing corrosion and scaling. The inner cavity is shot-blasted to remove weld slag and burrs. After welding, a leakage test is conducted to ensure there are no hidden dangers.

Core functions and roles

As the “hydraulic oil storage and purification core” of the SY1250H, its core functions are oil storage, impurity sedimentation, and heat dissipation. It provides clean and stable oil for components such as hydraulic pumps, balances the pressure inside and outside the oil tank, and prevents oil leakage and contamination. This avoids oil-related failures, extends the service life of hydraulic oil and components, reduces operation and maintenance costs, and works in conjunction with cooling pipes, hydraulic pumps, etc., to form a hydraulic protection system. It is a key assembly for ensuring stable mining operations.

Applicable Scenarios

It is widely used in the hydraulic system of SY1250H machine, and is suitable for oil storage, oil supply, sedimentation and filtration, etc. It connects to components such as SSY009114936 cooling pipes[3][8]. It can also be used in large mining excavators of the same specifications. It is suitable for open-pit mines and earthwork projects with 24-hour continuous heavy load and harsh working conditions. It is an essential hydraulic core assembly for equipment manufacturing, overhaul, after-sales maintenance and bulk purchase. It can reduce the cost of modification and downtime and improve the return on investment.
