First, the main purpose:

WAW-D series of computer controlled electro-hydraulic servo universal testing machine adopts the fuel tank mounted, four-column host, is mainly used for metal and nonmetal of tension, compression, bending and shear tests. Used in metallurgy, construction, light industry, aviation, aerospace, materials, universities, research institutes and other fields. Test operations and data processing line GB228-2010 "metal materials at room temperature tensile test method" requirements.

Second, the performance characteristics:

Host 1:

1.1 The oil cylinder mounted under tensile space at the top of the host, compression, bending test space located between the lower beams and a host table.

1.2 sturdy four-column two screw design, the whole strong stability.

1.3 moving beam design with a unique mechanism to eliminate the gap and avoid the experimental error D-type machine traverse beam by the force brought.

Between 1.4 and jaw jaw jaw with a 10mm slide, effectively extending the life of the jaw splint.

1.5 test space can be divided into three length adjustments of the sample according to the highest point applies to the use of high-temperature furnace and other peripheral devices.

1.6 oil cylinder clearance seal, which improves the measurement accuracy and increased service life.

2 Transmission:

By lifting beam with motor, cycloid reducer, sprockets, Vice drive screw nut to achieve tension, compression space adjustments.

3 hydraulic system (piano desktop oil source)

3.1 imported high pressure gear pump low noise, smooth pressure.

3.2 Dynamical Systems and console integrated design, easy to operate, saving space experiments.

3.3 surface by spray, beautiful appearance.

4 Control System

4.1 to achieve the test force, the specimen deformation of the four closed-loop control beam displacement and testing process;

4.2 data acquisition system consists of four high-precision 32-bit A / D converter channels. Maximum resolution of 1/500000, full, regardless of file;

4.3 selection of BB, AD, Xilinx and other original brand-name integrated devices, all-digital design;

Compliant with PCI 4.4 bus standard, microcomputer automatic identification and installation, so "plug and test";

4.5 electronic measuring system no potentiometer and other analog components to ensure interchangeability, easy maintenance and replacement.
