Product Detail

Pump Type: The main pump used in the Komatsu PC300 is a variable displacement axial piston pump.

It provides the excavator with a constant and reliable flow of hydraulic fluid. Maximum Flow Rate: The main pump of the PC300 has a maximum flow rate of around 500 liters per minute (L/min). This high flow rate ensures efficient hydraulic operation and increased productivity during excavation tasks. Pressure Rating: The main pump is designed to operate under high-pressure conditions. It typically has a maximum operating pressure of approximately 35 megapascals (MPa) or 5,075 pounds per square inch (psi). Parts and Components: a. Piston Block: The piston block consists of a series of pistons that reciprocate within cylinder bores. The pistons are responsible for generating hydraulic pressure by pushing the hydraulic fluid through the system. b. Cylinder Block: The cylinder block houses the piston assembly and is responsible for guiding the pistons as they move back and forth. It ensures smooth operation and maintains alignment of the pistons. c. Swash Plate: The swash plate is a key component that allows the adjustment of the pump's displacement. By changing the angle of the swash plate, the pump's output flow can be varied, enabling control over the hydraulic functions of the excavator.

d. Valve Plate: The valve plate controls the flow of hydraulic fluid to and from the piston block.

It consists of a series of valves that direct the fluid in the desired direction, enabling the main pump to provide both forward and reverse hydraulic power. e. Drive Shaft: The drive shaft connects the main pump to the engine of the excavator. It transfers the rotational power from the engine to the pump, driving its operation. f. Bearings and Seals: The main pump incorporates various bearings and seals to reduce friction, prevent leakage, and ensure smooth and efficient operation. These components are critical for maintaining the pump's reliability and longevity. g. Filtration System: The main pump often includes an integrated filtration system that removes contaminants from the hydraulic fluid, ensuring clean and debris-free operation. This helps protect the pump and other hydraulic components from damage and extends their service life.
