Product details

The HPV145 is a hydraulic main pump model commonly used in Hitachi excavators, specifically in the 300, 330, 350, and 360 series. These excavators are known for their heavy-duty performance and reliability, and the HPV145 pump plays a crucial role in their hydraulic systems.

Main Pump Parts and Assemblies

The main pump parts and assemblies for the Hitachi 300/330/350/360 excavators, including the HPV145 model, may include but are not limited to:

1. Pump Body and Housing: The main structure that houses the internal components of the pump.

2. Pistons and Cylinders: The moving parts that create the hydraulic pressure.

3. Valves and Controls: Regulate the flow and pressure of the hydraulic fluid.

4. Bearings and Seals: Ensure smooth rotation and prevent leakage.

5. Shafts and Gears: Transmit power and motion within the pump.

HPV145 Direct Injection and Electronic Fuel Injection

In the context of the HPV145 pump, direct injection and electronic fuel injection refer to the fuel delivery systems used in the engine that powers the excavator:

1. Direct Injection: This system injects fuel directly into the cylinders of the engine, improving fuel efficiency and reducing emissions. It requires precise timing and control to ensure optimal combustion.

2. Electronic Fuel Injection (EFI): This system uses electronics to control the fuel injection process. It monitors engine parameters such as speed, load, and temperature, and adjusts the fuel delivery accordingly to maintain optimal performance and efficiency.

For the HPV145 pump specifically, while it is a hydraulic component, its operation is often closely linked to the engine's fuel injection system. Ensuring that the fuel injection system is functioning correctly is crucial for the overall performance and reliability of the excavator.
