Tensile testing machine use maintenance precautions

In the process of using the pull machine, pay attention to the use of the pull machine. The maintenance and maintenance of the pull machine can effectively extend the service life of the pull machine and make the pull machine play a greater role in our product testing. Here, Kunshan Haida instrument details the precautions for use and maintenance of tensile testing machines.

First, electronic tension testing machine should pay attention before using:

1, the surrounding environment.

2, the power supply voltage.

3, boot detection.

4, the host must be grounded.

Two. Electronic Rally machine to use during the operation of the beam inspection

(1) The speed is stable at each speed.

(2) Whether each speed is normal.

(3) Operating distance, whether overshoot.

(4) belt and tension.

Three.Electronic tension machine control panel necessary checkpoint

(1) Panel display function.

(2) Panel key functions.

Four.Electronic tensile testing machine rack must be lubricated

Five. The electronic load system must be checked

Six, strain system inspection

(1) Calibration and zeroing of the extensometer: measure the standard length.

7. Electronic tensioning machine transmission system inspection (motor brush)

VIII. Inspection of accessories, such as pneumatic clamps, air compression pumps, foot switches, etc.

Comprehensive maintenance and maintenance of electronic tensile testing machine in the later period:

1. Before testing, the tensile tester must ensure that the system is warmed up more than 20 minutes in advance so as to minimize the influence of temperature.

2. The buffer oil should be kept clean. If the oil level is less than two-thirds of the depth of the barrel, it should be replaced immediately.

3. Before starting the tension strength tester, check whether the frictional active parts should be filled with lubricating oil.

4. Before holding the test piece, the brake handle must be stuck, and then add the test piece and release it.

5, dynamometer main bearings do not allow refueling. The surface of the friction wheel in the gearbox must not be oiled or splashed with oil. The friction surface must be clean and clean, and the bevel block on the swing arm must not be violently impacted.

6, after the test is completed, cut off the power, then give the test machine for surface cleaning, timely protection, to prevent surface rust.

7, on average every month to 2 to 3 times maintenance of the pulling machine.
