The WDW Series Microcomputer-Controlled Ring Stiffness Testing Machine is a specialized mechanical testing instrument designed to measure the ring stiffness of large-diameter plastic pipes with circular cross-sections. Controlled by a microcomputer, the machine delivers high-precision test data and is widely used in fields such as higher education, new materials research, construction material testing, and quality inspection.
Core Design and Advantages
- High-Rigidity Main Unit Structure: The main unit features high-strength cylindrical supports and a high-precision ball screw drive, delivering exceptional rigidity and linear motion characteristics.
- Multi-Column Guidance & Self-Lubrication: A multi-column guidance system enhances lateral rigidity and ensures linear stability during crosshead movement, while the self-lubricating design eliminates the need for routine maintenance.
- Precision Control System: Utilizes a fully digital closed-loop control system that supports constant-speed deformation, constant-speed loading, constant-speed displacement, and various cyclic testing functions.
- Intelligent Software: The accompanying FastTest V1.2 software offers a simple, fast, and user-friendly interface, significantly streamlining the testing workflow.
- Drive & Measurement: Equipped with a high-performance servo motor and an integrated extensometer to ensure testing stability and precise deformation measurement.
- International Certification: The equipment holds ISO and CE certifications, complying with international quality standards.
Frequently Asked Questions (FAQ)
Q1: What is the primary application of the WDW series testing machine?
A: It is primarily used to measure the ring stiffness of large-diameter plastic pipes—a key indicator for evaluating a pipe's resistance to external pressure.
Q2: Can the equipment be adjusted to accommodate different testing ranges?
A: Yes. By selecting load cells with different capacities, the equipment can provide precise data for testing various pipe structures and specifications.
Q3: Is the maintenance cost for this equipment high?
A: No, it is low. Thanks to the use of ball screws and a self-lubricating design, the equipment operates stably and eliminates the need for routine maintenance, thereby reducing both maintenance costs and downtime.
Q4: Are there specific electrical requirements for installation?
A: The equipment operates on standard 220V mains power (AC 220V ±10%) with a power consumption of 1.5kW, making installation very convenient.
Q5: What is the testing width, and what size pipes can it accommodate?
A: It features an effective testing width of 1000mm and a compression space of 1500mm, meeting the testing requirements for the vast majority of large-diameter plastic pipes.
