How to improve the temperature uniformity of the metal hot and cold impact box? Whether the test temperature is uniform is a particularly important issue, so how can the deviation of the temperature uniformity of the equipment be reduced when the operator is in use? Today, Haida Xiaobian analyzes the following questions for everyone:
1. Reduce the supply air temperature and increase the air supply volume: the air supply temperature difference and the air supply volume depend on the cooling load or the heat load.
2. Improve the rationality and perfection of the machine structure design: the structure is symmetrical. For example, two fans need one left-handed and one right-handed to make the air uniform. It is also possible to install a wind deflector at the air outlet to make the temperature uniform.
3. Increase the wind speed under the conditions allowed by the test side, enhance the flow of air in the tank, avoid the dead zone, and make the temperature inside the box even.
4. When using the equipment, observe the volume and weight of the sample and the position of the working space of the equipment.
5, improve the control accuracy of the equipment to reduce the temperature fluctuations can reduce the temperature deviation.
6. Adjust the median value of the temperature field to reduce the temperature deviation.
The above are a few small methods to stabilize the temperature uniformity of the metal thermal shock box. I hope that I can help you. Let me introduce the core steps of this equipment:
1. Before using the equipment and impact drill, check the insulation protection, auxiliary handle and depth gauge adjustment of the machine, and whether the screws are loose.
2. Check whether the power supply matches the regular rated 220V voltage on the power tool before use.
3, protect the wire, it is strictly prohibited to drag, to prevent rolling, cutting and other phenomena.
4. It is necessary to load the alloy steel impact drill or the perforated universal drill with the allowable range between φ6-25MM according to the material requirements.
5. When replacing the drill bit, use the wrench and the drill bit to lock the key to prevent the impact drill from being hit with a special tool.
6. Do not use excessive force or skew operation during use. Always tighten the appropriate drill bit and adjust the impact drill beforehand.
7. The power outlet should be equipped with a leakage switch device to check whether the power cord is damaged. If the impact drill is found to be abnormal, stop working immediately and repair it.
