11 operation steps of cement electric bending tester

Release time: September 7, 2020 popularity: two hundred and fifty-nine

   Cement electric bending tester Two large and small oil cylinders are used to test the compressive strength and flexural strength of cement respectively. The high-precision digital servo valve has the function of force closed-loop control, which can realize equal load rate loading or equal stress rate loading. Electronic measurement and automatic test are realized by microcomputer.

The system includes digital servo valve, high precision sensor, controller and software. It has high control precision and good reliability. It is suitable for one channel or two channel microcomputer control. The compressive mechanical properties of cement, mortar, concrete, brick and other building materials are tested by hydraulic servo control technology. The loading force value, loading speed and loading curve are displayed. The test data are processed, stored and printed automatically, and the data can be uploaded online.

The control cabinet and the compression host are designed separately, with beautiful appearance and convenient operation. Hydraulic loading is adopted, and the performance is stable and reliable. The transmission efficiency is high and the transmission is stable. The electric screw adjusts the test space, which improves the test efficiency and reduces the labor intensity. The integrated industrial computer, with multiple interfaces reserved, is convenient for networking.

Operation steps of cement bending tester:

1. Turn on the main switch.

2. According to the sample, select the measuring range, hang or remove the pendulum on the swing rod, adjust the handle of buffer valve, and align the marking line.

3. Install the corresponding chuck into the upper and lower jaw seat according to the sample shape and size.

4. Roll and press the recording paper (checkerboard paper) on the drum of the tracer, which is only carried out when necessary.

5. Turn on the oil pump motor, screw off the oil delivery valve to make the test bed lift paper 10 mm, and then close the oil valve. If the test bench is in the rising position, it is not necessary to turn on the oil pump to supply oil, just close the oil delivery valve.

6. Clamp one end of the sample in the upper jaw.

7. Start the oil pump and adjust the pointer to the zero point of the dial.

8. Start the lower jaw motor, lift the lower jaw to a proper height, clamp the other end of the sample in the lower jaw, and pay attention to make the sample vertical.

9. Put down the drawing pen on the push rod and enter the drawing preparation state (only when painting is needed).

10. According to the loading speed required by the test, slowly open the oil delivery valve for loading test.

11. Close the oil valve and stop the oil pump motor after the sample is broken.
