The JS140 is a hydraulic excavator manufactured by JCB, equipped with a sophisticated hydraulic system to ensure optimal performance and efficiency. Here's an overview of the hydraulic piston pump system in the JS140:

🔧 Hydraulic System Overview

• Main Pumps: The JS140 is equipped with two variable displacement axial piston pumps. These pumps adjust their displacement based on the load, providing efficient power delivery to various hydraulic functions. Control System: The hydraulic system utilizes a load-sensing, flow-on-demand system. This means the system adjusts the flow of hydraulic fluid based on the load requirements, ensuring energy efficiency and reducing fuel consumption.

• Pump Configuration: The pumps are of a tandem double axial piston type, with each pump section capable of independent operation. This design allows for precise control and distribution of hydraulic power to different functions.

What Comprises a Hydraulic Power Unit? A hydraulic power unit is a self-contained system that consists primarily of a motor, a hydraulic pump, and a reservoir. It converts mechanical power into hydraulic energy – a combination of flow and pressure used by a variety of machinery and equipment.

The filter is intended for direct mounting on hydraulic reservoirs in mobile installations and machine tool applications and can be used with any mineral and petroleum based oils. It requires one inlet fitting and discharges directly into the reservoir.

Features:

• It has a disposable spin on element on a die cast aluminium head
• Visual clogging indicator is available
• Easy installation and change of element

Hydraulic System Components

• Reservoir. The purpose of the hydraulic reservoir is to hold a volume of fluid, transfer heat from the system, allow solid contaminants to settle and facilitate the release of air and moisture from the fluid.
