Main types of engineering machinery parts
2025-06-30
Machined Parts
Definition: Components manufactured through machining processes, such as shafts, gears, and bearings.
Application: Transmit power, support rotating components, such as drive shafts and gearbox gears.
Characteristics: Requires high-precision machining, materials are mostly alloy steel or cast iron, directly affecting mechanical transmission efficiency.
Hydraulic System Components
Definition: Core components of the hydraulic transmission system, such as hydraulic pumps, hydraulic cylinders, hydraulic valves, and filters.
Application: Hydraulic pumps provide power, hydraulic cylinders drive actuators, and filters filter impurities to protect the system.
Characteristics: Requires high sealing performance, materials are mostly cast steel or high-strength alloys, and strict cleanliness requirements are needed.
Electrical Components
Definition: Components that provide electrical drive and control functions, such as motors, controllers, sensors, and switches.
Application: Motors drive hydraulic pumps, controllers adjust equipment operating parameters, and sensors monitor pressure and temperature.
Characteristics: Requires dust and water resistance, some components require explosion-proof design, and adaptation to harsh working conditions.
Safety System Components
Definition: Devices that ensure the safe operation of equipment, such as safety valves, emergency braking devices, and limit switches.
Application: Safety valves prevent overpressure in the hydraulic system, and emergency braking devices stop the equipment in case of danger.
Characteristics: Requires high reliability, materials are mostly high-strength steel or special alloys, and undergo rigorous testing.
Working Devices and Attachments
Definition: Components that directly perform work tasks, such as buckets, breakers, grabs, and rippers.
Application: Buckets are used for excavation, breakers for rock breaking, and grabs for material handling.
Characteristics: Requires high wear resistance, materials are mostly high-manganese steel or alloy steel, and the design needs to match the equipment model.
