Understanding Engineering Machinery Components
Here are some explanations of key engineering machinery components:
Hydraulic Pump (液压泵): The heart of the hydraulic system in an excavator. It converts mechanical power from the engine into hydraulic pressure, supplying high-pressure fluid to various actuators. Installation Location (安装部位): Usually mounted directly to the engine or transmission. Example: Hitachi Excavator ZAX200, Hydraulic Pump, Part Number: 9266465.
Travel Final Motor Drive (行走马达总成): A hydraulic motor and gearbox assembly that provides the rotational power to the excavator's tracks, enabling it to move. Installation Location (安装部位): Located within the excavator's undercarriage, connected to the tracks. Example: Komatsu Excavator PC200-8, Travel Motor, Part Number: 708-1W-00131.
Hydraulic Cylinder (液压缸): A linear actuator that converts hydraulic power into linear motion. Used in various parts of the excavator like the boom, arm, and bucket. Installation Location (安装部位): Attached to the machine's frame and the moving component. Example: Caterpillar Excavator 320D, Boom Cylinder, Part Number: 245-7817.
Control Valve (控制阀): Directs the flow of hydraulic fluid from the pump to the actuators, controlling the speed and direction of movement. Installation Location (安装部位): Typically located near the hydraulic pump or in a central manifold. Example: Kobelco Excavator SK200-8, Main Control Valve, Part Number: YN22E00037F1.
Hydraulic Hose (液压软管): Flexible hoses that carry high-pressure hydraulic fluid between the pump, valves, cylinders, and motors. Installation Location (安装部位): Connecting various hydraulic components throughout the machine. Example: Volvo Excavator EC210B, Hydraulic Hose, Part Number: VOE14533496.
Engine Assembly (发动机总成): The power source of the excavator, typically a diesel engine, providing mechanical power to drive the hydraulic pump and other systems. Installation Location (安装部位): Located in the main compartment of the excavator. Example: Cummins Engine NTA855-G1, Assembly, Part Number: 205133.
Boom (动臂): The main lifting arm of the excavator. Installation Location (安装部位): Pivoted to the excavator's upper structure. Example: Doosan Excavator DX225LC-9C, Boom, Part Number: 2190-9013.
Arm (Stick) (斗杆): The second arm connected to the boom, which holds the bucket. Installation Location (安装部位): Hinged to the end of the boom. Example: Sany Excavator SY215C, Arm, Part Number: 10312257.
Bucket (铲斗): The attachment used for digging and moving material. Installation Location (安装部位): Attached to the end of the arm. Example: John Deere Excavator 270D LC, Bucket, Part Number: 9169328.
Swing Motor (回转马达): The hydraulic motor that allows the excavator's upper structure to rotate. Installation Location (安装部位): Located in the upper structure, connected to the swing reduction unit. Example: Kawasaki Swing Motor K3V112SDH for various excavators, Part Number: K3V112SDH-9N21.
Common Questions about Engineering Machinery
What are the main types of hydraulic pumps used in excavators?
The primary types include gear pumps, piston pumps (axial and radial), and vane pumps. Piston pumps are most common in modern excavators due to their high efficiency and pressure capabilities.
How often should I change the hydraulic fluid in my excavator?
The recommended interval varies depending on the excavator model and operating conditions. Generally, it's between 2,000 to 4,000 hours, but always refer to the manufacturer's manual for specific guidelines.
What could cause my excavator to lose hydraulic power?
Possible causes include low hydraulic fluid levels, a faulty hydraulic pump, internal leaks in cylinders or valves, a clogged hydraulic filter, or issues with the engine not providing enough power to the pump.

Common Engine Issue and Solution
Engine Overheating: One frequent problem in engineering machinery engines is overheating. This can be caused by various factors such as a coolant leak, a clogged radiator, a faulty thermostat, or a malfunctioning water pump. If the engine overheats, it can lead to severe damage to critical components like the cylinder head gasket, pistons, and even the engine block.
Solution: First, safely stop the machine and allow the engine to cool down. Check the coolant level and look for any visible leaks. Inspect the radiator for obstructions and clean it if necessary. Ensure the thermostat is functioning correctly (it should open at the specified temperature). If the water pump is suspected to be faulty (e.g., leaking or not circulating coolant), it should be replaced. Regularly maintaining the cooling system, including flushing the radiator and replacing coolant according to the manufacturer's recommendations, can prevent overheating issues.
