Test steps and fault treatment methods for microcomputer pipe ring stiffness tester

The microcomputer tube ring stiffness tester is mainly used in mechanical tests such as tensile tests, ring stiffness, flattening, ring flexibility, etc. The pipe ring stiffness test machine is a new generation of dual-space microcomputer controlled testing machine designed for colleges and universities, science institutes, and quality inspection institutions. It can complete various mechanical properties tests such as tensile, compression, ring stiffness, and bending of the sample.

The force value and deformation value measured by the pipes during constant speed deformation of the microcomputer pipe ring stiffness tester determine the ring stiffness. Place the pipe sample horizontally, determine the compression speed of the plate according to the diameter of the pipe, and apply pressure to the sample in vertical directions of two plates parallel to each other. Reaction force is generated during deformation, and the ring stiffness is calculated using the force value when the deformation amount in the diameter direction of the tube sample is 0.03d. The pipe ring stiffness test machine is a new generation of dual-space microcomputer controlled testing machine designed for colleges and universities, science institutes, and quality inspection institutions. It can complete various mechanical properties tests such as tensile, compression, ring stiffness, and bending of the sample. Below, let’s briefly analyze the test steps and fault treatment methods of the microcomputer tube ring stiffness tester.

1. Test steps and methods of microcomputer pipe ring stiffness tester:

1. If it is possible to determine that the ring stiffness of the sample at a certain position is the smallest, put the position of sample a into contact with the press plate, or when placing the first sample, turn the position of the other two samples b and c 120° and 240° relative to the first sample in turn.

2. For each sample, place a deformation measuring instrument and check the angular position of the sample. When placing the sample, make its long axis parallel to the press plate and then place it in the center of the test machine. Make the upper plate and the sample in just in contact and hold the sample, compress the sample at a constant speed until at least 0.03d deformation is reached

3. Generally, the deformation amount is obtained by measuring the position of a pressure plate, but if the change in the thickness e of the pipe wall exceeds 10% during the sample process, it should be obtained by measuring the change in the inner diameter of the sample by diameter.

4. The test of the microcomputer pipe ring stiffness test machine should be carried out under 23℃±2℃

2. Fault treatment method for microcomputer pipe ring stiffness tester:

1. No response to operation: The most common thing is that the rising and falling keys of the beam have no response. Such a glitch causes the device to fail to work.

2. Do not place the microcomputer tube ring stiffness tester in places with high temperature, high humidity and strong magnetic fields. The magnetic field will affect the sensitivity of the buttons, and a humid environment will accelerate the damage of the electronic components of the instrument box, resulting in unpredictable problems. If the electronic components are damaged, you must contact the manufacturer to replace them.

3. Operation confusion: Due to the transmission signal problem, the functions of the keys overlap and intersect each other, which is caused by the inconsistency of the functions of each key, which leads to the failure of the experiment.

4. For the situation where the operation is not responded, first of all, it is necessary to determine whether the external power supply and transmission signal cable of the control box are connected correctly. If the rising key and falling key do not respond, the user can try to press other keys such as the speed key, return key, clear key, calibration key and other buttons to see if they are responded. If none of them are responded, the greatest possibility is the connection problem of the external power supply. If it is just simply rising and falling, then the test machine that needs to be checked next has touched the limit protection device switch. If the above problem still occurs after checking and confirming that the above problem is correct, it means that it is an internal problem of the instrument box. Then we must contact the manufacturer immediately for further inspection.
