WDW Series Double Column Door Type Double Screw Microcomputer Controlled Multifunctional Compression and Flexure Testing Machine

The WDW Series Double Column Door-Type Double Screw Microcomputer Controlled Multifunctional Compression and Flexure Testing Machine is a professional mechanical testing device developed and manufactured by Zhejiang Yiyu Instrument Equipment Co., Ltd. This machine is primarily used to test the flexural mechanical properties and bending strength of bricks, blocks, tiles, wall panels, and stone. It adopts a double-column door-type double screw structure with a wide lower space, allowing for testing not only core flexural and compressive strength but also tensile, shear, and other mechanical tests.

Core Design and Technical Highlights

High Rigidity Structural Design:

• Door-Type Double Screw Structure: The main unit uses high-strength cylindrical supports and high-precision ball screw transmission, ensuring high rigidity and excellent performance under large-space testing conditions.
• Multi-Column Guide System: Increases the lateral rigidity of the equipment, ensuring the stability of the linear movement of the crossbeam, and the self-lubricating structure achieves maintenance-free operation.

Precise Drive and Control:

• Servo Power System: The servo motor provides core assurance for experimental stability. Combined with synchronous belt drive, it features low maintenance and excellent force/speed characteristics.
• Fully Digital Closed-Loop Control: Supports constant velocity deformation, constant velocity loading, constant velocity displacement, and multiple cyclic functions, ensuring a high degree of automation and accuracy in the testing process.

Convenience and Durability:

• Flexible Adjustment: The fixture span adjustment is supported by linear guides, allowing for smooth sliding adjustments; quick couplings facilitate easy and quick replacement of different fixtures.
• Durable Components: Heavy-duty bearings ensure long-term stable operation, providing accurate and repeatable test results.

User-Friendly Interaction:

• The equipment is equipped with an independent control cabinet workbench, including a monitor and keyboard, allowing operators to monitor data curves in real time.

Standards Compliance

This equipment is designed to strictly comply with multiple national standards, including but not limited to:

Frequently Asked Questions (FAQ)

Q1: Which industries is this WDW series product primarily intended for?

A: It is particularly suitable for building material testing institutions, wall material manufacturers, and research institutes, specifically for testing the flexural strength of various large wall panels, new blocks, roofing tiles, and stone materials.

Q2: Besides flexural testing, can it also perform tensile testing?

A: Yes. This machine is equipped with a fixture interface that can be used to add tensile and compression functions. By changing the corresponding quick-connect fixtures, multi-functional testing can be achieved.

Q3: What are the advantages of the 1000mm effective test width?

A: The extra-wide test space (1000mm) allows the equipment to directly accommodate and test large-sized building wall panels or paving bricks (up to 1000×1000mm) without excessive cutting of the samples.

Q4: Why does this equipment use ball screw drives?

A: The ball screw, combined with heavy-duty bearings, ensures extremely high displacement accuracy and data repeatability even under long-term high-load operation.

Q5: Are there any requirements for the laboratory power supply when installing this equipment?

A: Its design is very user-friendly; it only requires standard 220V household electricity to operate, with a power consumption of 1.5kW, making it very suitable for most laboratory environments.
