Glossary of Related Terms:
- Axial Piston Pump (轴向柱塞泵): A type of hydraulic pump where the pistons move parallel to the axis of the cylinder block. Commonly found in excavators like the Hitachi ZX200, the main hydraulic pump with part number 9192463600 is an example. It is a key component in the hydraulic system.
- Gear Pump (齿轮泵): A positive displacement pump that uses meshing gears to pump fluid by displacement. Often used for lower pressure applications within the hydraulic system of mining equipment, such as lubrication systems. For instance, a lubrication oil pump for a Komatsu PC300 might have a part number like 6742-01-3770.
- Hydraulic Cylinder (液压缸): A linear actuator that is used to push or pull mechanical linkages. Excavators utilize numerous hydraulic cylinders, such as the boom cylinder on a Volvo EC210, which could have a part number around VOE14527318.
- Control Valve (控制阀): Directs the flow of hydraulic fluid within the system to control the movement of actuators like cylinders and motors. In a Caterpillar 320 excavator, the main control valve assembly might have a part number similar to 246-6267.
- Hydraulic Motor (液压马达): Converts hydraulic fluid power into rotary motion, used in travel final drives and swing mechanisms. A swing motor for a Kobelco SK200-8 could have a part number like YN15V00041F1.
- Travel Motor (行走马达): A specific type of hydraulic motor used to power the movement of tracked or wheeled machinery. Found in excavators, a travel motor assembly for a Doosan DX225 might be identified by part number 2713-1007.
- Final Drive (行走减速器): A gearbox connected to the travel motor that reduces the motor's high-speed, low-torque output to a lower speed, higher torque suitable for moving the machine. The final drive unit for a Hitachi EX60 often includes a part number such as 9144150010.
- Swash Plate (斜盘): A component in some axial piston pumps that controls the stroke length of the pistons, thereby regulating the output flow rate. Located inside the hydraulic pump of many machinery engines.
- Planetary Gear Set (行星齿轮组): A gear system consisting of a sun gear, planet gears, a ring gear, and a carrier. Commonly used in travel final drives to achieve high reduction ratios in a compact space, as seen in various excavator models.
- Spool Valve (滑阀): A type of directional control valve where a cylindrical spool slides within a bore to open or close ports, directing hydraulic fluid flow. Used extensively in the control valve assemblies of hydraulic systems in construction machinery.
Frequently Asked Questions (FAQs):
- What types of excavator parts do you specialize in?
SWAFLY MACHINERY CO., LIMITED specializes in a wide range of excavator parts including undercarriage components, engine parts, hydraulic components such as hydraulic pumps, hydraulic cylinders, and control valves, as well as travel final motor drives.
- Do you offer parts for brands other than Hitachi?
Yes, besides offering the Hitachi 4259254 BUSHING, we also supply parts for various other brands, including KUBOTA and Yanmar agricultural tractor engines, as well as components for other major construction and mining equipment manufacturers.
- What is the difference between OEM and aftermarket parts?
OEM (Original Equipment Manufacturer) parts are produced by the original manufacturer of the equipment. Aftermarket parts are produced by other manufacturers and can often offer a cost-effective alternative while still meeting quality standards. SWAFLY MACHINERY CO., LIMITED provides both OEM and high-quality aftermarket options.
Common Construction Machinery Engine Issue & Solution: Overheating
One common issue with machinery engines is overheating. This can be caused by several factors, including a low coolant level, a malfunctioning thermostat, a clogged radiator, or a faulty water pump.
Troubleshooting Steps:
- Check Coolant Level: Ensure the coolant level in the radiator and expansion tank is within the recommended range. If low, top it up with the correct type of coolant.
- Inspect Radiator: Check the radiator for any external blockages such as debris, dirt, or bent fins. Clean the radiator thoroughly using compressed air or water. Also, inspect for leaks.
- Thermostat Check: A faulty thermostat can prevent proper coolant circulation. If you suspect a thermostat issue, it may need to be tested or replaced.
- Water Pump Inspection: A malfunctioning water pump won't circulate coolant effectively. Look for signs of leakage from the water pump or unusual noises. The water pump belt should also be checked for proper tension and wear.
- Check for Internal Leaks: If the above steps don't resolve the overheating, there might be an internal leak, such as a head gasket issue. This often presents with white smoke from the exhaust or coolant in the engine oil, and requires professional diagnosis.
Regular maintenance and timely checks can help prevent engine overheating issues.
