Product Introduction

 

  YD-D type electro-hydraulic proportional servo testing experimental platform

 

Overview:
Hydraulic electro-hydraulic proportional servo control technology is a new type of hydraulic control technology that has developed and applied with the development of hydraulic transmission technology. Its control accuracy and response speed are far higher than ordinary hydraulic transmissions, and are widely used in modern industrial production. In the experimental teaching of hydraulic technology, the static and dynamic performance testing of servo valves can enable students to intuitively understand the performance and main parameters of the core components of the servo system. The YD-D type electro-hydraulic servo testing platform designed and developed by our unit can meet the requirements of experimental teaching and scientific research development in higher education and vocational colleges. And new experimental projects can be added after upgrading according to the actual needs of the site, with good scalability. This experiment is divided into two parts, one is the servo valve part, and the other is the circuit experiment part.
Experimental content:
Master the basic skills of experiments, further understand the application of mechatronics technology and computer-aided testing (CAT) technology, and improve students' testing skills and hands-on abilities. Understand the static and dynamic characteristics of electro-hydraulic servo valves, and master the experimental analysis methods for their performance testing. Understand the response characteristics of the electro-hydraulic servo valve controlled hydraulic cylinder system (open-loop, closed-loop) under sinusoidal and step inputs, and deepen the understanding of feedback control.
Composition of the experimental platform: The experimental platform consists of several parts, including the experimental workbench, hydraulic pump station, commonly used hydraulic components, electrical control unit, servo testing part, data acquisition system, etc.
(1) Experimental workbench
The experimental workbench is composed of a metal plate body and an aluminum operating panel. Hydraulic components can be easily and freely installed, and experimental circuits can be overlapped.
(2) Hydraulic pump station
The system provides dual pump unit rated working pressure: 25Mpa, 7Mpa
Motor pump device (2 units)
Variable displacement plunger pump - motor
Variable displacement plunger pump: unidirectional, nominal displacement 17.8Ml, r, rated pressure 25Mpa
Motor: three-phase AC voltage, speed 1450r/min
Variable Vane Pump - Motor
Variable vane pump: rated pressure 7Mpa, nominal displacement 11ml/r
Motor: three-phase AC voltage, speed 1450r/min
Technical parameters:
1. Adopting a data acquisition system, experimental data collection, analysis and processing can be carried out
2. Static flow measurement accuracy<2%, dynamic flow measurement bandwidth>100Hz, pressure measurement accuracy<2%, pressure measurement bandwidth>100Hz
3. Working power supply: 24VDC/4.5A
4. The software has good openness and provides a program interface for secondary development
5. Rated flow rate of pump station: 6.67L/min
6. Workbench size: long × wide × Height=2000mm × 750mm × 1850mm (approximately 300KG after packaging)
