Main uses, scope of application, functional characteristics and operating procedures of microcomputer hydraulic universal testing machine

The microcomputer hydraulic universal testing machine uses hydraulic pressure to apply test force. In order to ensure the high accuracy of the test force reading of the test machine, this machine uses a hydraulic sensor to measure the force. After amplification, the digital displays the test force, force peak value, and loading rate. The hydraulic system is mainly controlled manually, which is more convenient to operate, safe and reliable. The jaw clamping part is divided into manual clamping and hydraulic clamping. Adding the attachment can expand the test range, and the accuracy of the test force display is one level. This time I will share with you the main uses, scope of application, functional characteristics and operating procedures of microcomputer hydraulic universal testing machine. Let’s take a look.

Main uses and scope of application of microcomputer hydraulic universal testing machine:

Microcomputer hydraulic universal testing machine is mainly used for tensile, compression, bending and shear tests of metals and plastics, concrete, cement and other non-metals. Add simple accessories to complete the mechanical properties tests of tape, chain, wire rope, welding rod and components. It can be widely used in machinery, building materials, metallurgy, scientific research units, colleges and universities, quality testing centers and commodity inspection departments. It is an ideal testing machine for the industry requirements of production, scientific research and teaching.

Functions and features of microcomputer hydraulic universal testing machine:

1. The microcomputer hydraulic universal testing machine adopts manual oil return valve control, hydraulic loading, electronic measurement and automatic processing of microcomputer data. It mainly completes tensile, compression and bending tests of metal materials and non-metallic materials, and fully complies with the standards of: GB/T16826-2008 "Electro-hydraulic servo universal testing machine" and GB/T228-2002 "Metal Material Room Temperature Tensile Test Method"; it can also meet the experimental requirements for materials in: ISO, ASTM, JIS and other standards. The upper yield force and lower yield force can be automatically obtained, and various mechanical properties indicators such as non-proportional elongation strength, specified total elongation strength, tensile strength, elastic modulus, and elongation under maximum force can be determined. After adding accessories, the mechanical properties test of high-strength bolts, chains, wire ropes and other materials can be completed.

2. The main unit of the microcomputer hydraulic universal test machine adopts a double-screw mid-beam transmission mechanism, with a hydraulic cylinder underneath, and a fully open jaw seat, which is convenient to install the sample, good stability, and beautiful shape.

3. The microcomputer hydraulic universal testing machine uses a computer to complete the setting of test parameters, the collection, processing, analysis, storage and display of test curves during the test process (data includes: elastic modulus E, tensile strength Rm, upper and lower yield point ReH, ReL and other indicators, etc.).

4. The microcomputer hydraulic universal testing machine is equipped with Windows microcomputer screen display testing machine special software, which measures the performance parameters of each material according to national standards or standards provided by users, and statistics and processing of the test data, and outputs and prints various required test curves and test reports.

Operating procedures of microcomputer hydraulic universal testing machine:

1. Turn on the power supply, turn on the system power supply, turn on the display switch, select the load range according to the sample, and enter the known conditions of the sample.

2. Turn on the hydraulic universal test oil pump motor of the microcomputer, unscrew the oil supply valve to raise the piston for a period of time, and let the oil cylinder hang. Select and install different tools according to the different contents of the test. If tensile tests, select and install a suitable tensile jaw clamp.

3. Place the sample on the main unit of the test machine. For example, if the tensile test is performed, turn on the oil pump switch, clamp one end of the sample into at least 4/5 of the length of the jaw, open the upper jaw electric switch to clamp the sample, run the cross beam, and let the sample run to the upper jaw and penetrate deep into the jaw at least 4/5 of the length position, stop rising, and open the lower jaw electric switch to clamp the sample. (This is the model of automatic clamping of the sample. Another manual clamping only requires manual clamping of the sample)

4. Unscrew the oil pump switch, turn on the oil pump, and slowly unscrew the oil feed valve according to the loading rate required by the test. When the sample breaks, close the oil supply valve and stop the oil pump motor.

5. Record the value from the microcomputer hydraulic universal testing machine microcomputer display screen or print data directly from the microcomputer. After the data is correct, open the oil return valve to restore the instrument to its initial state.

6. Remove the broken sample, turn off the screen switch and power supply, wipe and clean the surface of the instrument, pay attention to the daily maintenance of the microcomputer hydraulic universal test machine
