Tensile testing machine should pay attention to waterproof and moisture resistance

Before we buy the universal tensile testing machine The definitive one Purchase usually takes place after comparison and information from several dealers. After purchasing the universal tensile testing machine, care and maintenance of the universal tensile testing machine must be taken into account in addition to daily use. The so-called maintenance, we only need to do the daily maintenance. The following is a brief introduction of some daily maintenance methods of the universal tensile testing machine. 9r4Textile Testing Instruments, Testing Equipment Manufacturer

First, the universal tensile testing machine is a great precision testing instruments should special attention should be paid to water and moisture resistance, and anti-rust oil should be applied frequently to prevent rusting. As long as you do this well, you shouldn't have any problems. 9r4Textile Testing Instruments, Testing Equipment Manufacturer

Second, the rusty parts of the machine are often attached anti-rust oil. Corrosion and rust are the main reasons for the destruction of this firmware, which will cause great damage on various vehicles. According to statistics, the annual economic loss caused by metal rust accounts for about 2% to 4% of the national economy's total output value. Therefore, the firmware of the instrument must strengthen the anti-rust work and cooperate in the selection of appropriate cleaning agents, packaging materials, etc., so that the anti-rust oil can play its due role, otherwise the best effect cannot be achieved by simply applying anti-rust oil. 9r4Textile Testing Instruments, Testing Equipment Manufacturer

Third, you should pay attention to the relative position of the jaws or Slider Holdthe surface clean and avoid bumps. Remove the dirt in the jaws in time. If the jaw ruler is blocked, please use a steel brush dipped in gasoline to clean it. Never use hard tools to clean it. In order not to damage the jaw ruler. 9r4Textile Testing Instruments, Testing Equipment Manufacturer

Universal tensile testing machine performs tensile measurement The most common mistake is that the sample material is always broken on both sides, it needs to be broken from the middle and only one place is broken. The picture is not an error or anything, but something went wrong during the operation of the test machine. When such an error occurs, you should first think about whether the local fixture of the testing machine main body is vertical, and then check whether the jaws are placed correctly when clamping. If the first two points look goodare guided, the quality of the jaws will be poor and the teeth will be damaged. In addition to affecting the misalignment of the jaws, the specimen will slip during the test, making it difficult to identify the yield point This time, the jaws should be replaced. Finally, the reason for this phenomenon may be that the adjustment of the elevator idler wheel may not be correct, so the upper and lower jaws are not concentric. At this point, a control bar should be processed. After the upper and lower jaws are tightened, measure with a dial indicator based on the two columns of force until the adjustment is qualified. 9r4Textile Testing Instruments, Testing Equipment Manufacturer
