The dry weather in winter weather is low, Winter weather drying temperature is low, because the principle of thermal expansion and contraction,Whether metal or non-metal, it will become harder and more brittle.For mechanics laboratory generally have a temperature requirements,and avoid the sample being too brittle and the experimental results are not accurate,also avoid the steel strand tensile tester because the temperature is too low, can not be turned on, or the experimental data error after booting.

In the winter, the steel strand tensile tester is used indoors. It is recommended to maintain the temperature at around 20°.It is not recommended to use a tensile testing machine outdoors, and the temperature is too low to open the machine.Secondly, the lubrication of the winter test machine is more important, and the lubrication of the clamp and the chuck should be paid more attention.It is recommended again that the warm-up time is a little longer than in summer.

In addition, there are the following things to note:

1. Regularly apply anti-rust oil to the fixture to prevent long-term oxidation and rusting of the equipment.
2. Check the tightness of the device itself and related accessories screws to prevent it from falling off.
3. Due to the high frequency of the experiment, the condition of the electrical connection wires in the controller is checked regularly.
4. The steel strand tensile testing machine needs to replace the filter element in time to prevent the valve body from being blocked.
5. Observe the condition of the hydraulic oil, replenish it regularly, and preheat it before starting it to make more accurate measurements.
