SANY Hydraulic Components Introduction
Compound Pump Unit: As the heart of the hydraulic system, it typically comprises multiple pump bodies, simultaneously powering multiple independent actions of the excavator (such as boom, stick, and swing), forming the technological foundation for achieving efficient compound actions.
Gear Pump: Compact in structure, it typically provides a stable oil flow for auxiliary functions in the hydraulic system (such as pilot control and cooling circulation).
Piston Motor: Converts the energy of high-pressure hydraulic fluid into powerful rotational torque. Depending on system requirements, there are different types such as swashplate and swashplate motors, with a wide range of displacements, and it is the core component driving the slewing platform and traveling mechanism.
Reducer: Usually integrated with the motor, serving as a slewing reducer or traveling reducer. It lowers the high speed output of the motor and significantly increases the output torque, directly driving the excavator's upper slewing or lower traveling mechanism.
Bucket Cylinder: One of the "end" actuators of the hydraulic system. A high-quality bucket cylinder directly reflects digging force, employing special materials and advanced welding and surface treatment processes, possessing extremely high reliability and impact resistance.
Specialized sealing package: Used for precision sealing of hydraulic cylinders and valve blocks. It ensures no leakage of high-pressure oil and is the core guarantee for maintaining stable pressure, precise operation, and long-term maintenance-free operation of the entire hydraulic system.
