173-0663 Hydraulic Main Pump Excavator Hydraulic Pump for Excavator 312C 312D

the advantages of hydraulic pump:
1, High Power Density: Hydraulic pumps can convert mechanical energy into hydraulic energy with high efficiency, which means they can generate a large amount of force or torque in a relatively small package. This makes them suitable for appliCATEEEEEEions requiring heavy lifting, moving, or pressing.

2, MultipliCATEEEEEEion of Force: Hydraulic systems allow for the multipliCATEEEEEEion of force through the use of hydraulic cylinders and motors. The pressure generated by the pump can be transmitted through pipes to multiple actuators, allowing a small force on the pump to create a much larger force at the output.

3, Smooth and Precise Operation: Hydraulic pumps offer smooth and consistent operation because they provide continuous flow and can be easily controlled by adjusting the input speed or valve settings. They are often used in appliCATEEEEEEions that require precise control, such as machine tools and aircraft controls.

4, Load Sensitivity: Hydraulic pumps are inherently load-sensitive, meaning they can automatically adjust their output according to the demands of the system. When there's no load, the pump doesn't need to work as hard, conserving energy.

5, Damping and Shock Absorption: The inherent compressibility of hydraulic fluids provides a natural form of shock absorption within the system, which can protect machinery from sudden impacts or overloads.

6, Versatility: Hydraulic pumps can be designed to operate in various positions and orientations, making them suitable for a wide range of appliCATEEEEEEions. They can also be powered by different sources like electric motors, engines, or even manual effort.

7, Easy Control: The flow rate and direction of hydraulic fluid can be easily controlled using valves, enabling quick and accurate adjustments to system performance.

Long Life Span: Hydraulic pumps are typically built robustly and can withstand harsh conditions, leading to long service lives if properly maintained.
