Technical Glossary: Hydraulic Pumps and Travel Final Motor Drives
Hydraulic Pump - 主液压泵 (Zhǔ yèyā bēng): The main component in the hydraulic system that converts mechanical power into hydraulic power. It is typically installed in the engine compartment and connected to the engine's power output.
Example: Hitachi ZX200-3 uses a Kawasaki K3V112DP main hydraulic pump with part number 9264319.
Gear Pump - 齿轮泵 (Chǐlún bèng): A type of positive displacement pump that uses meshing gears to pump fluid. Often used for auxiliary functions.
Example: Hitachi EX60-5 utilizes a gear pump for pilot control with part number 4286117.
Piston Pump - 柱塞泵 (Zhùsāi bèng): A type of positive displacement pump that uses reciprocating pistons to move fluid. Commonly used as the main hydraulic pump in excavators.
Example: Hitachi ZX330-5G is equipped with a Kayaba PSVD2-27E piston pump, part number 9270563.
Travel Final Drive - 行走减速器 (Xíngzǒu jiǎnsù qì): The gearbox that reduces the high-speed, low-torque output of the travel motor to a lower speed, higher torque output needed to drive the tracks. Located within the undercarriage, connected to the tracks.
Example: Hitachi ZX210LC-5 uses a travel final drive with part number 9257308.
Swing Motor - 回转马达 (Huízhuǎn mǎdá): The hydraulic motor that powers the rotation of the excavator's upper structure. Mounted on the upper frame of the excavator.
Example: Hitachi EX120-5 has a swing motor with part number 4364801.
Control Valve - 控制阀 (Kòngzhì fá): Directs the flow of hydraulic fluid to various actuators (cylinders, motors) in the hydraulic system. Typically located centrally in the hydraulic system.
Example: Hitachi ZX240-3 features a control valve with part number 9266901.
Boom Cylinder - 动臂油缸 (Dòngbì yóugāng): The hydraulic cylinder responsible for raising and lowering the excavator's boom. Attached to the main frame and the boom arm.
Example: Hitachi EX200-5 uses a boom cylinder with part number 4436057.
Pilot Pump - 先导泵 (Xiāndǎo bèng): A small hydraulic pump that provides the pilot pressure needed to operate the main control valve. Usually mounted near the main hydraulic pump.
Example: Hitachi ZX360H-3 has a pilot pump with part number 9268104.
Track Roller - 支重轮 (Zhīzhòng lún): Wheels located on the undercarriage that support the weight of the excavator and allow the tracks to move smoothly. Positioned along the length of the track frame.
Example: Hitachi ZX225USLC-5B uses track rollers with part number 9280001.
Slew Ring - 回转支承 (Huízhuǎn zhīchēng): A large bearing that allows the upper structure of the excavator to rotate 360 degrees. Located between the undercarriage and the upper structure.
Example: Hitachi EX300-5 is equipped with a slew ring with part number 4384201.
