In the previous article, test machine Lao Er shared with you the common sense of the ability of universal material test machine and related operating procedures. I believe you have a further understanding of the universal material test machine.
Then, the second test machine will talk to you about the maintenance of the universal material test machine, hoping to ensure that the test instrument has a longer service life.
universal material testing machine, also known as electronic universal material testing machine , is mainly equipped with high-precision Huang Anqi, servo control system, servo motor , high-precision ball bearings and screws, shock absorbers, fixtures, etc.
As a high-precision testing instrument, when the universal material testing machine conducts mechanical properties testing of the samples, even if the operating standard is performed, it will still cause considerable wear or damage to the test instrument. Therefore, in order to extend the service life of the test instrument, it is particularly necessary to carry out regular maintenance!
Regarding maintenance, the second tester believes that we should pay special attention to the three core parts, including the host, control system and oil source.
Host maintenance:
1. The fixtures equipped with the machine should be coated with anti-rust oil for storage;
2. Since the jaws of the hydraulic universal testing machine are often used, they are easy to wear. If there are too many scale , it is easy to cause damage to small pistons, so the jaws should be cleaned frequently and kept clean (it is best to clean after each test);
3. The sliding surface of the steel plate in contact with lining plate and the dovetail groove surface on the lining plate should be kept clean, and a thin layer of MoS2 is applied regularly. ( Molybdenum disulfide ) Lubricating grease;
4. Regularly check the screws in the jaw area. If it is found to be loose, tighten it in time;
5. Regularly check the transmission status of sprocket . If it is found to be loose, please re-tension the tensioner ;
Oil source maintenance:
1. Regularly check whether there is oil leakage in the host and oil source. If there is oil leakage, replace the sealing ring or combination pad in time;
2. According to the use of the machine and the service life of the oil, regularly replace the oil suction filter and filter element, and replace the hydraulic oil .
3. When not doing tests for a long time, be careful to turn off the host power supply. If the machine is in standby state, conversion switch should be turned to the "load" setting, because if the conversion switch is turned to the "quick reversal" setting, the electromagnetic reversing valve is always in the power-on state, which will affect the service life of the device.
Control system maintenance
1. Regularly check whether the connection cable of the back panel of the controller is in good contact. If it is loose, it should be tightened in time;
2. If there is a long period of time after the test, turn off the controller and the computer;
3. The interface on the controller corresponds one by one, and the wrong interface may cause damage to the device;
4. The interface on the plug-in and unplug the controller must turn off the controller power.
or above is the explanation of the test machine's maintenance method for three core components such as the universal material test machine host, control system and oil source. If you want to know more about the test machine: principle, performance, parameters, usage, detection, operation, measurement, maintenance, technology, three-dimensional diagram, assembly drawing, structural diagram, schematic diagram, mechanical diagram, exploded diagram, circuit diagram, etc., welcome to chat with the test machine in the background, and the test machine can provide you with free consultation!
