Operation steps of polymer testing machine

There are many places where the polymer testing machine is used. Generally, when using this type of product, there will be some masters to teach the novice how to operate, and the product will have corresponding instructions for use, and there will be corresponding usage methods on it. However, no matter what kind of equipment is used for operation, there may be problems. It is very important to understand the operation steps of the polymer testing machine in detail. Only the correct operation of the polymer testing machine can play its role. So how to operate is better? Let's find out. 1. Select the measurement range according to the sample, hang or remove the pendulum thallium on the pendulum rod and adjust the handle of the buffer valve to align with the marking line. 2. Install the corresponding chuck into the upper and lower jaw seats according to the shape and size of the sample 3. On the drum of the plotter, roll and press the recording paper (graph paper), this is only done when necessary. 4. Start the oil pump motor, unscrew the oil feed valve to make the test bench rise by 10 mm, and then close the oil valve. If the test bench is already in the raised position, it is not necessary to turn on the oil pump to send oil first, just close the oil feed valve. . 5. Clamp one end of the sample into the upper jaw. 6. Start the oil pump to adjust the pointer to the zero point of the dial. 7. Start the lower jaw motor, lift the lower jaw to an appropriate height, clamp the other end of the sample in the lower jaw, and make sure that the sample is vertical. 8. Put down the drawing pen on the push rod and enter the drawing ready state (only when drawing is required). 9. According to the loading speed required by the test, slowly unscrew the oil delivery valve to carry out the loading test. 10. After the sample is broken, close the oil valve and stop the oil pump motor. 11 Record the required value and will draw it. 12. Open the oil return valve. After unloading, turn the passive needle back to zero. 13. Remove the fractured sample. 14. Compression and bending tests can be carried out with reference to the above items. Don't think that the polymer testing machine can be used up as long as you follow the correct method of use. In fact, there are corresponding tips when using the polymer testing machine, and these tips will only be discovered after a long period of use. Yes, if you want to know in advance, you can also consult some experienced masters. I believe you can learn a lot of useful knowledge. If you have any questions, you can also consult us.
