Single Space Electro-hydraulic Servo Universal Testing Machine

Model: WAW-F Series


WAW-F series single space Servo-Hydraulic Testing System Computerized is suitable for testing tension, compression and other strengths of various metallic or nonmetallic materials with high strength. The ultra-large testing space & dual-action actuator with longer stroke enable it to test not only standard specimen, but also longer ones with long elongation every so often. Equipped with the electronics, computer &software packages, it is capable of controlling the test procedures by the predetermined programs. The Servo-Hydraulic Testing System Computerized can also display, record, process and print the test results. The test curves can be drawn automatically in real time. The Servo-Hydraulic Tester of Single Space is easy to operate and is versatile in the applications of metallurgy manufacturers such as steel mills & alloy, reinforced bar, aircraft industry, research institutes, laboratories, calibration institutes etc.

Structure Load frame features

WAW-F series adopts single testing space designed with single central hydraulic drive for loading on specimen directly to do the tests of tensile, compression, bending and shearing etc.. The space created by counter force frame structure is totally eliminated so that the testing results are more accurate and real. The single large test space fully considers operation convenience and safety that raise testing efficiency. Such a large test space also entitles the load frame to adapt a wide range of specimen sizes, grips, accessories, extensometers, furnace, environmental chambers etc.. For the load capacity of 300kN, it has two-column structure, while for the load capacity from 500kN-3000kN, it has four-column structure.

Hydraulic power pack
1. Constant pressure and fixed flow rate servo power pack is adopted in the famous and advanced design. The power pack is designed with two constant pressure systems of quick response for loading and clamping.
2. The Servo-Hydraulic Testing System Computerized is capable of low pressure start-up, medium and high pressure switch-over.
3. The oil source consist of fixed oil pump, high and low pressure switch-over module, air cooling device and electric control cabinet.
4. On the front panel, function buttons like main oil pump control, clamping pump control and emergency stop are equipped for easy operation of the computer control electro-hydraulic servo testing system.
5. Intelligent and environmental friendly air cooling device can start and stop at preset temperature.
6. Safety features: oil level protection, oil actuator overflow protection, oil pump over current protection, hydraulic oil overheating protection, overload protection and filter protection.
7. To start and stop the oil pump can be done through software.
8. Two oil filters with high filter grade are installed to ensure the cleanness of the servo system and the actuator’s endurance.
9. Pressure gauges to show the main pressure of the system and the clamping pressure
