Function summary:
SHT4106G microcomputer controlled electro-hydraulic servo universal testing machine adopts double space cylinder lower structure。There is a compression space between the test bench and the lower beam, which can realize the compression, bending, shearing test of the sample.The tensile space is between the lower beam and the upper beam, and the tensile test of the sample is mainly carried out。The test space is automatically adjusted by rotating the lead screw to move the lower beam up and down。The closed-loop servo control system composed of electrical controller, servo valve, load sensor, displacement sensor, extensometer and computer can control the test process automatically and accurately, and measure test parameters such as test force, displacement and deformation automatically。
The testing machine is mainly used for tensile test of prestressed concrete steel strand, which meets the standard GB/T 5224。
The computer and the measurement and control system collect the test data and send the control instructions, which can automatically control the test process and automatically calculate the test results, and display the test curve and the test result in real time by the microcomputer screen, and print the test report and the test curve by the printer。The system has a return function, after the test, the loading cylinder piston can automatically or manually return to the initial position。
Test software built-in standard network interface, test data can be transmitted to the network through this standard interface, the software manual and help documents have detailed description of this interface and the use of configuration methods, network software through this interface and test software data exchange and transmission。We assist users in networking, but do not customize the network interface for users alone, nor do we assume the responsibility for consultation and coordination with the relevant network companies。If it involves sending software personnel to the user site service, corresponding fees will be charged。
