Tensile testing machine is a high-precision, high-tech material testing equipment, which can be used to perform tensile, compression, bending, shearing, peeling and other mechanical performance tests on metallic and non-metallic materials. It has become the main equipment for material inspection now because it has the advantages of easy operation and high accuracy.

However, if we buy a tensile tester that is not of high quality because of the price, it may cause the test data to be inaccurate. If the test fails due to unskilled human factors, its use value will be greatly reduced.

1.Cleaning and maintenance: During the course of the experiment, there is no preventable dust that will occur, such as scale and non-metallic debris.If it is not cleaned when there is no overlap, there will be no wear and tear only on the surface of some complete machines. Scratches, etc., are even more serious. If the department's dust enters the hydraulic system of the electro-hydraulic servo tensile testing machine, very serious consequences such as clogging the valve hole and scratching the surface of gōu will occur, because cleaning after each use is very critical It is necessary to maintain the health of the testing machine;

2.Use a suitable tenon to end the echoing experiment. Without the light, the experiment will not be smooth. Moreover, the tenon will be protected: the electro-hydraulic servo tensile testing machine is generally only equipped with a tenon that is used as a standard sample. Specimens, such as steel strands, overlapped steel, etc., must be equipped with compliant tenons; some super-angle materials, such as spring steel, must use special material clips, otherwise they will protect the tenon ;

3.Hydraulic oil: It is necessary to always check the liquid level of the fuel tank and replenish the oil in time; generally, the oil needs to be changed every 2000 to 4000 hours; however, the most important thing is that the oil temperature does not exceed 70 ° C, and it must be opened when the oil temperature exceeds 60 ° C. Icing system;

4. Accumulators: Some electro-hydraulic servo tensile testing machines are equipped with accumulators. It must be guaranteed that the pressure of the accumulator lies in the abnormal mission situation. If you find that the pressure is not applied, you need to compensate the pressure immediately; only charge the accumulator. Nitrogen;

5. Filters: For filters without clogging indicators, they are generally exchanged every 6 months. For the filter with clogging indicator, it must be constantly monitored, and it must be exchanged immediately when the indicator alarms;

6.Monitoring inspection of element parts: All pressure control valves, flow control valves, pump conditioners, and signal facilities such as pressure relays, distance switches, thermal relays, etc., must be stopped and checked;

7.Icing device: The scale of the air-cooled ice device must be determined; the selection of the electric cooling device must be used to check whether the icing copper pipe has cracked water;

8.Smooth oil: All the screws and drives of the electro-hydraulic servo tensile testing machine should be coated with smooth oil to prevent dry friction from occurring;

9.The fasteners of the electro-hydraulic servo tensile testing machine must be stopped and locked: the vibration of the sample pull cover often causes some fasteners to loosen. It is necessary to stop the inspection (the deformity uses 30 mission days and outside) ) To prevent large losses due to loose fasteners.

10. The rest of the inspection: step back and be vigilant and pay close attention to the details, so that early warning of the accident can be detected to prevent major accidents. This is especially true when entering the operation at the beginning of the facility. Should not pay attention to external disclosure, purification, element protection and abnormal noise from pumps, couplings, etc.
