Hydraulic pump parts

As the core power component of hydraulic systems, hydraulic pumps feature complex and precision-engineered components. The following provides a detailed introduction across three aspects: core components, auxiliary components, and specialized components unique to different pump types:

First, Core parts of hydraulic pump

1. Pump Housing: Serving as the hydraulic pump's outer structure, the housing encloses the pump's rotating components, providing containment and support. It protects internal parts from external environmental damage and ensures stable pump operation.

2. Rotor: The primary moving element within the hydraulic pump, responsible for converting mechanical energy into fluid pressure energy. The rotor's motion pattern is closely tied to the pump type, such as gears in gear pumps, vane rotors in vane pumps, or pistons in piston pumps.

3. Shaft: Connects the motor to the pump body, transmitting mechanical power. Typically crafted from high-strength materials, the shaft withstands rotational torque and pressure, ensuring efficient and stable pump operation.

4. Sealing Devices: Prevent fluid leakage and maintain system pressure. Common sealing materials like rubber and nylon effectively contain hydraulic fluid, guaranteeing system functionality.

Second, Auxiliary parts of hydraulic pump

1. Inlet/Outlet Valves: Regulate fluid flow to ensure proper hydraulic system operation. These valves precisely regulate fluid flow rate and direction according to system requirements, enabling accurate control of hydraulic actuators.

2. Oil Seals and Gaskets: Similar to sealing devices but primarily focused on preventing hydraulic fluid leakage from the pump housing to the external environment. They are typically installed at critical pump locations such as shaft ends and pump covers to ensure sealing integrity.

3. Inlet/Outlet Connectors: Interfaces linking the hydraulic pump to the reservoir or other hydraulic components. They ensure smooth oil flow within the system and prevent leakage at connection points.

4. Pressure Valves and Relief Valves: Regulate system pressure to protect against overpressure. When pressure exceeds set limits, these valves automatically open to release excess fluid, safeguarding the system from damage.

5. Thermometers and Pressure Gauges: Monitor the temperature and pressure within the hydraulic system. They provide real-time display of the system's operating status, helping operators promptly identify and address potential issues.

6. Hydraulic Hoses and Accessories: Connect various hydraulic components and transport fluid. The quality of hoses and accessories directly impacts the stability and reliability of the hydraulic system. Therefore, it is essential to select hoses and accessories that are reliable, corrosion-resistant, and capable of withstanding high pressure.

Third, Distinct parts of Different Hydraulic Pump Types

1. Gear Pump:

Gears: The core components responsible for fluid conveyance and pressure amplification. Parameters such as tooth profile, number of teeth, and module directly influence gear pump performance.

Side Plates: Protect internal pump components while enhancing structural strength and rigidity. These plates typically fit tightly with the pump body to ensure stable gear pump operation.

2. Vane Pumps:

Vane: The key component of a vane pump, responsible for creating volumetric changes during rotor rotation to achieve fluid delivery. Parameters such as the vane's material, shape, and quantity directly affect the pump's performance.

Stator: Works in conjunction with the vane to form a sealed space for volumetric changes. The shape and dimensions of the stator's inner surface significantly impact the vane pump's performance.

3. Plunger Pump:

Plunger: The core component of the plunger pump, responsible for reciprocating motion within the pump cylinder to achieve liquid delivery. Parameters such as the plunger's material, diameter, and stroke directly affect the pump's performance.

Swashplate: Works in conjunction with the plunger. By altering the swashplate's angle, the flow rate of the plunger pump is regulated. The design and adjustment of the swashplate are crucial for performance control.
