Components of Hydraulic Pump

Pump Body:

The pump body consists of a front cover, middle shell, back cover, and bearing seat, protecting the internal rotor and inlet/outlet from external influences. Material selection is crucial, requiring corrosion resistance, high strength, and temperature resistance.

Rotor:

The rotor is a core component, responsible for propelling fluid Flow within the pump. It must be smooth, flat, and wear-resistant. Rotors in hydraulic pumps typically include gears, blades, or vanes, depending on the pump type and structure.

Bearings:

Bearings reduce internal friction and resistance, ensuring the pump operates smoothly. Common types include roller and plain bearings, chosen based on specific requirements.

Seals:

Seals prevent internal leaks, including front cover seals, shaft seals, inlet seals, and outlet seals. These seals are made from durable materials like rubber, linen, or leather to maintain pump integrity.

Inlet and Outlet:

The inlet and outlet connect to the hydraulic circuit, drawing in fluid and outputting compressed fluid to the system. The inlet is usually located at the top, while the outlet is positioned at the bottom or side.

Fluid Path:

The fluid path encompasses the flow path within the pump, including the suction port, pressure chamber, discharge port, and pressure relief valve. Proper design and layout directly impact the efficiency and stability of the hydraulic pump.

Conclusion:

Hydraulic Pumps play a vital role in hydraulic transmission machinery, featuring complex structures due to the coordination of various components. This article introduced the main elements of hydraulic pumps, aiming to assist readers in understanding their functionality and importance.
