Electrohydraulic Servo Universal Testing Machine

Product Description

WAW-300B/600B/1000B
Computer Control Electrohydraulic Servo Universal Testing Machine

Main functions & features:
1. This machine adopts computer controlled digital broadbrand electrohydraulic servo valve to drive precision hydraulic cylinder to perform automatic control to test force, displacement, deformation in many modes and thus finishes tests of tension, compression and bending. It accords with standard requirements of GB/T228-2002 Method for Tensile Test of Metallic Materials at Room Temperature and GB/T3159-92 Hydraulic Universal Testing Machine. If added with accessories, it can perfom mechanical performance tests for high strength bolt, chain and steel wire etc.

2. Utilizing downsetting hydraulic cylinder, and its power of adjusting test space and transmission mechanism are installed the bottom of machine, stable transimission. Its upper and lower jaw bases are open, easy to install specimen and with good stability.

3. Independent hydraulic servo loading system, adopting high precision broadbrand electrohydraulic servo valve to make sure that system is high precision, high efficiency, low noise, fast response. And its independent hydraulic clamping system makes system low noise, smooth operation. During test, specimen is clamped tightly and nonslip.

4. Utilizing computer control, completely realizing three closed loops to test force, displacement, strain. With accurate and reliable test procedure control, data acquisition, processing, analysis(test data including: Elasticity modulusE, tension strength RM, Upper and lower yield points ReH, ReL etc. ).
