The hydraulic main pump utilized in these models is a high-performance, variable-displacement pump designed to provide reliable and efficient power to the hydraulic system.
It features advanced technology and components to ensure optimal performance and longevity.
The pump is capable of delivering a variable flow of hydraulic fluid, allowing for precise control over the excavator's various hydraulic functions. This variable-displacement feature ensures that the pump supplies the necessary flow based on the load requirements, resulting in reduced energy consumption and improved efficiency.
The maximum operating pressure of the hydraulic main pump is an essential specification to consider. It determines the pump's ability to withstand high pressures and deliver the required power to the hydraulic system. The R60-7 and EC55 hydraulic main pump typically have a maximum operating pressure of around 3500 to 4000 pounds per square inch (psi), enabling them to handle demanding tasks with ease.
The flow rate of the hydraulic main pump is another critical specification. It defines the volume of hydraulic fluid the pump can deliver per unit of time.
The flow rate of the R60-7 and EC55 hydraulic main pump typically ranges from 100 to 150 liters per minute (L/min), ensuring an adequate supply of hydraulic fluid to the excavator's functions.
To ensure durability and reliability, the hydraulic main pump is constructed using high-quality materials and undergoes rigorous testing during the manufacturing process. The pump's housing is typically made of robust cast iron or aluminum alloy, providing excellent strength and resistance to wear and tear. The internal components, such as pistons, cylinders, and valves, are precision-engineered to ensure smooth operation and minimize friction.
The hydraulic main pump is driven by the excavator's engine through a belt or direct coupling, depending on the specific model. The power from the engine is transferred to the pump, which converts it into hydraulic energy to operate the various hydraulic functions, such as the boom, arm, and bucket movements.
