Newly purchasedElectronic Tissue Strength MachineAfter the installation is complete, power-on test is required. When conducting the power-on test, the following points must be noted to ensure that the purchased electronic tissue strength machine can work normally:
1. Horizontal Calibration
The electronic tissue strength machine needs to be horizontally calibrated during installation so that when testing, it will shrink due to the gravity belton the error.
Calibration method: There is a water bubble for level calibration behind the base of the electronic cloth gauge tester, adjust The height of the four machine feet under the base is such that the air bubbles in the bubbles are in the middle position.
Second, various wiring checks
Before commissioning of the electronic power machine, you must carefully check whether the power cord of the device is plugged in properly. Whether there is damage, whether the ground wire is reliable. If it is a microcomputer-controlled model, attention must also be paid to whether the data cable between the computer and the tissue attachmentmachine is working properly and properly connected.
Third, check the state of the moving bar
Turn on the power switch of the electronic fabric strength machine and the control computer, confirm that the program and control software of the instrument are running normally, and then check the working status of the moving beam.
1, moving crossbar up:Press the up button on the control panel (or the up button on the computer control software interface), the moving beam should move according to the preset speed move up in a straight line, und the running process is stable. When the moving beam touches the upper limit valve, it will stop running immediately and an overrun alarm will be displayed on the control interface.
2, moving crossbar down:Press the down button on the control panel (or the down button on the computer control software interface), the moving bar moves according to the set speed down in a straight line, and the down operation is smooth and the speed is steady. When the moving beam touches the lower limit valve, it will stop running immediately and an overrun alarm will be displayed on the control interface.
3, pull-off test simulation:When the movable crosshead is in the preset position, drPush the start button, the movable crosshead moves up in a straight line and applies a certain tensile force (generally ≥5% of full scale) on the jig at the end of the fabric strength tester where the sensor is installed. ), and then release it. When the tension disappears, the movable crossbar should immediately stop rising and rotate to a rapid fall until it returns to the starting position during the test.
