Dual Space Electro-hydraulic Servo Universal Testing Machine

Model: WAW-E Series

Description:

WAW-E series computer control servo-hydraulic testing machine is suitable for testing tension, compression, bending and shearing strength of various metallic & non-metallic materials. Equipped with the electronics, computer &software packages, the servo-hydraulic tester of dual space is capable of controlling the test procedures by the predetermined programs. The computer control servo-hydraulic testing machine can also display, record, process and print the test results. The test curves can be drawn automatically in real time. The servo-hydraulictesting machine is easy to operate and is versatile in the applications of metallurgy industries such as steel mills & alloy, reinforced bar, aircraft manufacturer, research institutes, laboratories, calibration institutes etc.

Load Frame Structure
Featuring a dual test space with high stiffness to meet extensive test applications, test loads are available from 300kN to 3000kN.
1. Compact design with rigid four-column & two-lead screw construction.
2. Dual work-space design. The upper one is for tension test (expandable for peel & tear test etc) while the lower one is for compression, bending and shearing tests, which is quite convenient for different kinds of tests.
3. The frames have considered all of the human factor into the design to ensure safety, improve testing efficiency, and reduce operators’ weariness.
4. Cylinder mounted at the bottom of the machine guarantees the working gravity.
5. Test space can be extended according to the length & elongation of specimen and other related test requirements.

Crosshead

The design of front open hydraulic wedge grips makes the exchange of inserts and specimen loading easier. Tensile grips are embedded into upper fixed and lower movable crosshead to keep maximum strength. Lower movable crosshead motor-driven by roller chain make the operation much easier.

Hydraulic power pack of servo-hydraulic Testing Machine

1. Variable pressure hydraulic power supply provides pressure on demand, reducing heat, extending oil life and eliminating the need for water cooling.
2. Double control mode, manual control & PC servo control model. For manual control model, hydraulic pack is for manually loading and clamping specimen hydraulically for high efficiency of test. While test data & curves can displayed on PC, manual control mode is especially suitable for the batch broken load tests on the large scale of specimens. For PC servo control mode, all can be controlled & processed by PC automatically. Closed-loop servo control of position, load, stress & strain increases the test efficiency and meets the data consistency between collection and analysis.
3. The pumping units are designed to be located in the lab with lower noise level within 65dBa.
4. The oil pump, as the core heart of the oil source, is the power source of the hydraulic system. MARZOCCHI pumps from Italy and the NACHI pumps from Japan are commonly used. The two oil pumps are high pressure gear pump, with low noise and steady performance.
