Although electronic universal testing machine and hydraulic universal testing machine belong to mechanical testing equipment, they have differences in driving power source, main body structure and application expansibility.Because of their great differences, they have their own characteristics in practical application. The following is a brief introduction to the specific differences between the two, hoping to help you better understand them

Choose the right product.

1、 Structural features

1. The electronic universal testing machine takes the servo motor as the driving power source and drives the servo motor to load through the control system. The whole machine is mainly composed of base, deceleration transmission system and ball

It is composed of lead screw pair, fixed beam, moving beam, force sensor, fixture (removable), measurement and control system, test software, etc. The main engine has compact structure and small occupied space. Compared with the hydraulic universal testing machine, the relative height is lower under the same test space conditions.

The structural form of electronic universal testing machine determines that it can be designed to cover different models with test force ranging from 0.1N to 2000kN, and can also be expanded on the same host

The force sensor and corresponding fixture are equipped with professional test software to realize a variety of tests with a wider range of force values.

The tension and compression space of electronic universal testing machine can be determined according to various environmental test chambers and high-temperature furnaces with expanded configuration, and the form of pull-down and up pressure or pull-up and down pressure can be adopted.

2. The hydraulic universal testing machine takes the hydraulic pump driven by asynchronous motor as the driving power source, and drives the servo valve to load through the control system. The whole machine is mainly composed of main engine, servo oil source

Measurement and control unit and test software.

The main engine of double space model is mainly composed of sealing base, actuator, test space adjustment lead screw, smooth screw, loading beam (integrated clamping jaw, built-in hydraulic clamping mechanism), force

Sensor, displacement sensor, measurement and control unit, test software, etc.

The main engine of single space model is mainly composed of bearing frame, actuator, hydraulic fixture, force sensor, displacement sensor, measurement and control unit, test software and so on.
