2 differences between different hydraulic universal testing machines

Hydraulic universal testing machineIt is a fully functional and stable experimental instrument. It has been widely used on the market. There are many models of this type of test machine. According to different models, the differences between different models are provided by Jinan Hengsi Shengda Instrument Co., Ltd.:

1.The difference between digital hydraulic universal, screen hydraulic universal and microcomputer control electrical servo universal:

First, the display data has different levels of comprehensiveness. The main display of the force value, strength, and force of the digital explicit-Time curve and yield strength of materials with obvious yield properties; the screen and microcomputer control electrical servo show various force values, strengths, elongation, fracture strength, upper and lower yield points, elastic modulus and various test curves. Secondly, the display method is different. The digital display displays the test data and results in real time, while the display displays the test data and results in the hydraulic universal test machine and the electrical servo universal test machine are displayed through the microcomputer screen. It means that the control method is different. Digital and screen explicit control flow into the oil cylinder by manually operating the oil supply valve and oil return valve. The microcomputer controls the electrical servo by computers to operate the hydraulic servo valve.

2.Digital hydraulic universal, screen displayHydraulic universal testing machineCommon points of the universal power of electro-hydraulic servo control with microcomputer:

First, their host form is the same. They all use the under-cylinder type, the tensile test space is located above the main machine, and the compressed and bent test space is located between the lower beam and the workbench above the main machine. The size of the test space is adjusted by moving the intermediate beam. Second, they work the same way. All the motors drive the high-pressure gear pump into the oil circuit and flow through the check valve.10uThe high-pressure oil filter, differential pressure valve group, and oil supply valve enter the oil cylinder. The amount of oil entering the oil cylinder is controlled by manually controlling the oil supply valve or microcomputer control servo valve, which meets the loading requirements and completes the test.
