The Gear Pump used in the Hitachi EX200-1 is a positive displacement pump that utilizes the meshing of gears to pump fluid.
It consists of two interlocking gears, the drive gear, and the driven gear. The drive gear is connected to the prime mover, typically an engine or electric motor, which transfers rotational force to the driven gear. As the gears rotate, they create a partial vacuum that draws fluid into the pump and then forces it out under pressure.
The Gear Pump in the Hitachi EX200-1 is designed to handle a wide range of hydraulic fluids, including mineral-based oils and synthetic fluids. It is constructed using high-quality materials to ensure durability and long service life even under demanding operating conditions. The pump is engineered to provide consistent and reliable performance, allowing the excavator to handle various tasks with ease.
One of the key specifications of the Gear Pump is its displacement capacity, which determines the volume of fluid it can deliver per revolution. The Hitachi EX200-1 Gear Pump has a displacement capacity of X cc/rev (cubic centimeters per revolution). This specification indicates the amount of hydraulic fluid that can be moved through the pump in a single revolution of the gears.
The Gear Pump is also rated for a specific pressure range. It can generate a maximum pressure of X bar (or X psi) to ensure adequate force for powering hydraulic cylinders and other hydraulic components. This pressure rating is crucial for achieving the necessary force and control in various excavation operations.
Another important specification is the pump's input speed range.
The Gear Pump in the Hitachi EX200-1 is designed to operate within a certain range of input speeds, typically between X and Y rpm (revolutions per minute). This specification ensures that the pump can function effectively within the designated speed range, allowing for efficient fluid delivery and system performance.
Additionally, the Gear Pump features a compact and lightweight design, making it suitable for integration into the excavator's hydraulic system. It is engineered to minimize energy loss and improve overall efficiency, contributing to fuel savings and reducing the environmental impact of the machine.
The Gear Pump in the Hitachi EX200-1 is also equipped with various safety features to protect the hydraulic system from damage. These may include pressure relief valves or bypass valves that prevent excessive pressure build-up, thereby preventing potential system failures.
