Tensile testing machine Microcomputer controlled electro-hydraulic servo horizontal tensile testing machine

Scope of application
The testing machine is used for tensile property testing of long flexible and rigid material structural parts and finished parts. With the addition of other testing equipment, tensile performance testing of structural parts can also be performed. It is widely used in structural laboratories and mechanics laboratories of pipeline engineering, electric power engineering, bridge engineering, petroleum industry, industrial and mining enterprises, scientific research institutes and colleges and universities.
Functional features
According to the structure, it is divided into three modes: single space, double space, double cylinder type
The cylinder piston and the reaction frame are connected through a spherical support and a load sensor, so that the specimen can be pulled During the stretching process, the force is more even and there is no lateral force.
The servo hydraulic source adopts a dual-pump system. When no-load, the low-pressure and large-flow pump operates to complete the fast forward and rewind of the piston
When loading, it automatically switches to a small-flow and high-pressure plunger pump, which consumes less power
The electrical console and oil source are integrated designs. The console has a built-in fully digital measurement and control system. The oil source system is a high-precision differential pressure servo system. The motor consumes power as the load changes, but the power loss is small, the heat is small, and the oil temperature rises low
The stretching space is adjusted by using electric steps. Each level mode can easily and quickly adapt to the requirements of various specimen lengths.
Retaining the manual valve, the machine is easy to debug and calibrate the force value, and has the function of a screen display machine
Full digital measurement controller, high resolution, and does not change throughout the entire process. It can realize closed-loop control of test force and displacement, and control constant test force, constant displacement, uniform stress rate and uniform displacement rate in a multi-step manner. The computer communicates with the measurement control system through the serial port and operates with a virtual keyboard on the Chinese/interface.
The test frame is equipped with a steel mesh protective cover to prevent the sample from splashing after being broken.
Test space, piston stroke and other indicators are determined according to user requirements.
