Flow Rate: The pump is capable of delivering a specific flow rate of hydraulic fluid, typically measured in liters per minute (LPM) or gallons per minute (GPM).
This flow rate determines the speed and power of the swinging motion.
Pressure Rating: The pump has a specified maximum pressure rating, often expressed in bars or pounds per square inch (PSI). This rating ensures the pump can handle the high pressures required for efficient hydraulic operation.
Size and Weight: The physical dimensions and weight of the pump are crucial factors for installation and compatibility within the excavator's hydraulic system.
Material Construction: The pump is typically constructed from high-quality materials such as cast iron or steel to withstand the rigors of heavy-duty applications and resist wear and corrosion.
Mounting Configuration: The pump's mounting configuration is designed to fit seamlessly into the excavator's hydraulic system, ensuring a secure and stable installation.
The primary function of the EX105-2 motor swing motor hydraulic pump is to convert mechanical power from the excavator's engine or electric motor into hydraulic power.
This hydraulic power is then used to drive the swinging motion of the excavator's upper structure. Here's how it functions:
Input Power: The pump receives mechanical power from the excavator's engine or motor. This power source is typically in the form of a rotating shaft.
Hydraulic Fluid Intake: The pump draws hydraulic fluid (usually hydraulic oil) from a reservoir or hydraulic tank.
Pressurization: Inside the pump, the hydraulic fluid is pressurized to a specific level. This is accomplished through a series of internal components such as pistons, gears, or vanes, depending on the pump type.
Fluid Delivery: The pressurized hydraulic fluid is then delivered to the swing motor, which is responsible for the rotation of the upper structure. The high-pressure fluid acts on the motor's pistons or vanes, causing them to move and initiate the swinging motion.
