1〠Test roller axial load tester:
Roller diameter measured: Φ245～Φ76
Measured roller length: ≤ 800mm (We can choose different length test according to customer's requirements, more than the standard length, need to be customized)
2, the design principle:
I, screw regulator, II, high-precision sensor Larry part, III, screw micro-adjustment device, IV, test specimen placement position, V, supported roller base support, multi-step, VI, force on the pressure device.
Use force on the pressure device to make the sample under test and the screw fine-tuning device contact, if you find that the length of the sample under test is not enough, you can use the fine-tuning device of the screw rod to fine-tune the distance, make the test more accurate, after the contact, make the force on the pressure device continue to press , Apply an axial load.
3, explain the use of the process:
I. Connect the outlet of the device to the power supply system securely, turn on the power supply, observe the stability of the power supply, and when the power supply is stable, prepare to start the test.
II, fixed sensor position, according to the installation requirements after the sensor is installed in place, check whether the installation is firm, and then connect the sensor under the link part of the solid sensor, observe the digital analysis instrument digital stability, if the sensor has a problem with the data display is not stable, If you find a similar problem, stop the trial and contact us.
III. According to the requirements of the testing machine, the upper pressure device is installed in a fixed position. After the installation is stabilized, the bottom tray is firmly mounted on the upper pressure device, and then the sample to be tested is vertically and stably placed on the roller supporting seat. IV. Adjust the height of the screw fine-tuning device according to the length of the idler. After the idler is in firm contact with the upper top plate, prepare the test.
V. During the process of adjusting the contact, adjust the position of the lower tray according to the position of the idler to ensure that the balance centerline of the inner roller and the centerline of the sensor are as vertical as possible to ensure the accuracy of the collection force value.
VI, use the pressure device to press, slowly increase force, when the sensor meter shows the reading reaches the specified load value of the roller, the pressure is stopped, if the reloading process, the inner shaft of the roller appears obvious destruction record The value of the damage can also be observed by a single-chip microcomputer after the test to observe the maximum force value. (meter reading in KN).
VII, uninstall the pressure system.
VIII. Check whether the change of the central axis of the roller (including the bearing seat and the sealing device) is separated from the roller outer pipe body. Those who are not detached are qualified, and the detachment is unqualified.
The end of the experiment!
