Engineer Mr. Leong maintain universal testing machine in Uzbekistan

HZ-1009 Dual Column Universal Tensile Testing Machine is a new material testing machine that combined with the electronic technology and mechanical transmission, it has accurate load speed, range of force measurement, Has high accuracy and sensitivity for the load, displacement measurement and control, This machine is simple to operate, simple structure, it can be directly placed on the testing table for test, especially suitable for controlling quality in production line This series of machine is mainly applied to test the non-metallic and metallic materials which the load is less than 100KN.

Standard

GB/T16491-1996 ,GB/T 528, GB/T 529, ISO 37, ASTM D412,ASTM D638,EN13986

Main Feature

This machine is suitable for stretching, compression, bending, shearing and peeling of materials and products in various textile, rubber, plastic, synthetic leather, tape, adhesive products, plastic film, composite materials, electronics, metal and other industries. A variety of tests, such as 90 degrees and 180 degrees), tearing, two-point extension (with an additional extensometer), to determine the quality of the product.

There may be many faults during the use of the tensile machine, which will affect its normal operation and the accuracy of the test results. The following are some common faults and their solutions:

Common faults and solutions
1. The main power supply has power but the equipment cannot move up and down: Check whether the equipment cannot move after 15S (time), because the main power needs to self-check, which takes about 15S; Check whether the upper and lower limits are in the appropriate position and have a certain running space; Check whether the power supply voltage connected to the test machine is normal.
2. After the computer software is connected, a prompt box message appears showing overload: Check whether the communication line between the computer and the test machine is detached; Check whether the sensor is selected correctly when selecting the online connection; Check whether the sensor has been hit during the recent test or keyboard operation.
3. The pendulum position is abnormal, and the pendulum rod is not aligned with the vertical mark: the viscosity of the oil is too dirty or too large, and the oil needs to be changed; the force measuring piston does not rotate and there is a lot of friction or movement, check whether it is horizontal to eliminate it.
4. The pendulum returns abnormally, sometimes fast and sometimes slow: the buffer valve gear position is improperly placed: adjust the buffer valve to the appropriate position. The viscosity of the hydraulic oil is too low or too high: When the viscosity of the hydraulic oil is too low, the pendulum falls back quickly, and when the viscosity is high, it falls back slowly. The hydraulic oil with appropriate viscosity should be replaced.

Preventive measures
1. Regular maintenance: Regularly maintain the tensile machine, including cleaning, lubrication and checking the wear of each component.
2. Correct operation: Strictly follow the operating procedures to avoid equipment damage caused by misoperation.
3. Software calibration: Make sure that the software has been correctly calibrated before use to avoid inaccurate test results due to software problems.
