Introduction
The ZX35U-3 is a compact excavator that relies heavily on its hydraulic system for efficient operation. One of the key components of this system is the pilot hose, which controls the various hydraulic functions of the machine. This article explores the layout and function of the pilot hoses in the ZX35U-3, providing an understanding of their importance and how they work together to power the excavator’s movements.
Overview of the Pilot System
The pilot system in the ZX35U-3 controls the hydraulic flow to the main components, such as the boom, arm, and bucket. It uses low-pressure hydraulic fluid to control high-pressure actuators, allowing for smooth operation of the machine. The pilot hoses are part of this system, connecting the control valves to the hydraulic cylinders that perform the tasks.

The pilot hose system in the ZX35U-3 is vital for controlling the excavator’s hydraulic functions. Understanding how the hoses work and maintaining them properly can extend the lifespan of the machine and ensure smooth, efficient operation. Regular inspections, replacements, and troubleshooting of any issues related to the pilot hoses are essential for maintaining optimal performance of the excavator.

Pilot Hose Diagram and Layout
- Pilot Hoses:
The pilot hoses are small-diameter lines that carry hydraulic fluid at lower pressure. These hoses are responsible for transmitting signals from the operator’s controls to the hydraulic valves, which then control the high-pressure circuits.
- Key Components of the System:
- Control Valve: Directs the hydraulic fluid based on inputs from the pilot hoses.
- Hydraulic Cylinders: Receive the high-pressure fluid and perform actions like lifting the boom or moving the bucket.
- Pilot Pump: Supplies the pressure required for the pilot system to function.
- Control Valve: Directs the hydraulic fluid based on inputs from the pilot hoses.
- Control of Hydraulic Functions:
The pilot hoses transmit control signals from the operator to the control valve. These signals are used to manage various hydraulic functions, such as controlling the boom, bucket, and swing. By adjusting the pressure in the pilot system, the operator can precisely control the movement of the excavator’s arms.
- Low-Pressure Fluid Transmission:
The pilot system operates at much lower pressure compared to the main hydraulic system. This allows for precise control without overloading the valves or other components.
- Flow Direction and Volume:
The flow of hydraulic fluid in the pilot hoses must be carefully regulated to ensure proper movement of the excavator's arms. If the hoses are damaged or the pressure is incorrect, it can cause malfunctioning of the hydraulic components.
- Signs of Damage:
If the pilot hoses become damaged or leak, the hydraulic system will not operate correctly. Common signs of issues include slow or unresponsive movements, erratic bucket or arm movements, or a drop in hydraulic pressure.
- Replacing the Hoses:
When replacing pilot hoses, it is crucial to use the correct specifications to ensure proper function. Incorrect hose sizes or materials can lead to pressure loss or hose failure.
- Checking for Blockages:
Over time, pilot hoses can become clogged with dirt or debris, which restricts the flow of hydraulic fluid. Regular inspection and cleaning of the hoses can prevent these blockages and keep the system functioning smoothly.
- Hydraulic System Health:
Regular maintenance of the pilot hoses and associated components is crucial for the overall health of the hydraulic system. Ensuring that the hoses are free from leaks, blockages, and damage helps maintain system efficiency and prevents expensive repairs.
- Inspection and Replacement:
It’s important to inspect the pilot hoses regularly for wear and tear. If the hoses show signs of damage, they should be replaced promptly to avoid further issues with the hydraulic system.
