Unlocking Precision and Efficiency: The Power of LEZUM DY??E Electro- Hydraulic Pilot Control Technology

In the realm of mini excavators, technological iteration and upgrades never cease.
From the initial purely mechanical control to today's intelligent electronic control systems, every leap aims to bring users a more superior operating experience and higher economic benefits. In this process, electro-hydraulic pilot control technology is undoubtedly one of the most eye-catching innovations in recent years. It has not only completely changed the way excavators operate but has also achieved a qualitative breakthrough in precision, efficiency, and intelligence. Today, we will delve into how the LEZUM DY12E mini excavator, with its advanced electro-hydraulic pilot control technology, becomes a powerful aid for you to achieve precise operations and efficient performance in various complex working conditions.

What is Electro-Hydraulic Pilot Control Technology?

To understand the power of electro-hydraulic pilot control technology, we first need to review the control methods of traditional hydraulic excavators. In traditional purely hydraulic systems, the operator directly drives hydraulic valves through joysticks, and the flow and pressure changes of hydraulic oil directly control the excavator's movements. While this method is mature and reliable, it has certain limitations in terms of operating force, precision, and response speed.

Electro-hydraulic pilot control technology introduces an intelligent brain"—the Electronic Control Unit (ECU). When the operator moves the joystick, instead of directly pushing the hydraulic valve, they send an electrical signal to the ECU. After receiving these signals, the ECU accurately calculates the optimal hydraulic flow and pressure requirements based on preset programs and real-time data collected by sensors (such as engine speed, hydraulic system pressure, load conditions, etc.). Subsequently, the ECU precisely controls the pilot oil circuit through electro-hydraulic proportional valves, which in turn drives the main valve, ultimately achieving precise control over all the excavator's movements.

In short, electro-hydraulic pilot control technology transforms the operator's intentions into precise electrical signals, which are then intelligently processed and optimized by the ECU, and finally, the hydraulic system is finely regulated through electronically controlled valves. This control chain of "electrical signal - intelligent processing - electronically controlled hydraulics" is the key to achieving superior performance.

The Secret of Precise Control: The Perfect Fusion of Micro-Movements and Compound Actions

One of the most significant advantages of electro-hydraulic pilot control technology is the unprecedented precision control it gives to mini excavators. In traditional hydraulic systems, the operator needs to apply considerable force to move the joysticks, and due to the inherent characteristics of mechanical connections, it is difficult to achieve very fine micro-movements. This often becomes a bottleneck for efficiency when performing fine grading, pipe laying, working in narrow spaces, or requiring precise material grabbing.

The electro-hydraulic pilot control system completely solves this problem. The operator only needs to gently move the joystick, and the electrical signal is instantly transmitted to the ECU. The ECU can control the opening of the proportional valves with extremely high frequency and precision, thus achieving stepless adjustment of the hydraulic flow. This means:

• Excellent Micro-Movement Capability: Even the slightest joystick displacement can be converted into a precise hydraulic output, enabling the excavator to perform fine adjustments at the centimeter or even millimeter level. For example, when trimming slopes or cleaning the bottom of trenches, it can achieve a level of precision close to manual operation.

• Smooth Compound Actions: In excavator operations, it is often necessary to perform multiple actions simultaneously, such as lifting the boom, extending the stick, and rotating the bucket. Traditional hydraulic systems often experience action delays or interference when performing compound actions. The electro-hydraulic pilot control system, through the intelligent coordination of the ECU, can optimize the flow distribution of each hydraulic circuit, ensuring that multiple actions remain smooth and coordinated when performed simultaneously, greatly improving operational efficiency and experience.

• Reduced Operator Fatigue: Since the joysticks no longer directly bear the hydraulic reaction force, the operator can perform all operations with minimal effort. The fatigue of long-term operation is significantly reduced, allowing the operator to maintain focus and efficiency for longer periods.

The Leap in Fuel Efficiency: Intelligent Matching, On-Demand Supply

In addition to precise control, electro-hydraulic pilot control technology also excels in improving fuel efficiency. Fuel consumption is a major part of the operating costs of an excavator, and any improvement in energy efficiency means real cost savings.

Traditional hydraulic excavators often have a suboptimal match between the engine and the hydraulic pump under non-full load conditions, leading to energy waste. For example, when the excavator is idling or in light-load operation, the hydraulic pump may still be outputting at a high flow rate, causing unnecessary fuel consumption.
