China Education Equipment Purchasing Network News: In addition to the high temperature, people can eat too much, and the same is true for machines, especially those with high heat generation. Like a projector, in the hot summer, it will also appear as a "heatstroke" symptom like a human. In fact, for those who know a little about the projector, they must know that the two natural enemies of the projector are dust and high temperature. So the arrival of summer is a big test for the projector.
Different protective measures in different regions
The so-called different areas, in fact, are mainly divided into north and south. Due to the different climates between north and south, the maintenance of the projector also requires different maintenance. Anyone who has been to the south will have the same feeling, that is, the humidity is higher than that of the north. The climate in the south is humid all the year round, especially in summer, when there is enough rain and the air is full of moisture, plus the rainy season, this is very important for the projector. The northern climate is characterized by dryness. For projectors, high temperatures are mainly considered in summer.
Since the projector is used for a long time, the dust or pollutants in the air are filtered. The surface of the dust filter at the vent of the projector will inevitably accumulate more and more dust or other pollutants. If it is not cleaned in time, the dust or contaminants may block the cooling vents, which will affect the cooling effect.
Therefore, the editor here recommends that users in the northern region must clean and clean the dust net from time to time to ensure that the dust or other contaminants on its surface are cleaned, so that the air path is clear. , The working temperature inside the projector can be effectively controlled, and some core components inside the projector are not susceptible to thermal damage. In addition to paying attention to the above problems, users in the southern region should also keep the room dry and dehumidify frequently, especially during the rainy season. If you do not clean it frequently, the life of the projector will be greatly shortened.
Users have different maintenance methods
Projectors are mainly divided into educational projectors, business projectors, home projectors, and engineering projectors, and this distinction also makes users different. For home projector users, good protection can be achieved at any time, such as the above-mentioned unscheduled cleaning and cleaning operations of the air filter, to ensure that the surface of the dust or other contaminants are cleaned in time . Business users often place it on the desktop when using the projector. At this time, try not to place any obstructions around the projector to ensure that there is enough space for the air inlet and air outlet and the bottom of the projector. Let the air flow freely and increase the heat dissipation of the projector. So for those users who use in large places, how to better deal with the "heat stroke" symptoms of summer projectors?
Of course, I hope that these users can achieve the above maintenance methods, but in reality, it is difficult to do, especially for users in large places, they will not assign a person to be responsible for maintenance. And when they choose, they will pay more attention to the dustproof function of the projector. Choosing a high-performance dustproof projector has become the first choice. In fact, this is also a way to maintain the projector. Good quality projectors will last longer and save a lot of unnecessary trouble.
The editor also found some excellent representatives for reference from many projector manufacturers. Acer projector's exclusive "Smart Three Dustproof" technology is one of them. Its exclusive dustproof technology, Smart Three Dustproof, through three dustproofs, completely rejects dust intrusion, and does not affect heat dissipation. The high-efficiency dust-proof and heat-dissipating design of the ASK projector is also very good. The unique S-shaped air path design allows the core of the lamp to fully contact with the cooling air, and conducts heat out and dust out, especially suitable for dust, The dusty classroom. In addition, the unique "dust wall" technology of ViewSonic projector is also very representative. It adopts a fully sealed dustproof shell design, which includes a fully sealed dustproof chassis and a fully sealed lens cover. It is also specially equipped with advanced three-dimensional electrostatic filter. This filter adopts a multi-layer design, which can realize deep filtration, and the contact area of ​​the filter is three times that of the ordinary filter. During the working process of the projector, this filter will actively absorb particles and smoke in the air through static electricity, and the dustproof efficiency is significantly higher than that of the ordinary filter.
Finally, when shutting down, it is necessary to pay attention, it is not appropriate to unplug the power quickly. After the projector is turned off, the cooling fan will still rely on electricity to run at a high speed for a period of time. The main purpose of this is to allow the lamp to cool to a minimum temperature after a long period of use, thus shortening when the fan stops working , The natural cooling time of the lamp, so after using the projection, users are advised to unplug the power after the fan completely stops working, so as to ensure that the projection can shorten the time of natural cooling after each use, also indirectly Play the role of extending the life of the lamp.
Deboning chicken is a time-consuming process and large meat processing plants deal with significant amounts of meat. Even if a plant employs a large number of workers to debone poultry manually, it will still be costlier and more time-consuming than utilizing deboning machines. Additionally, manual deboning has a negative effect on the freshness and quality of the meat. To solve these problems, Helper deboners provide excellent efficiency and output.
You can preprocess the poultry by cutting them into parts, and then efficiently debone separated meat by Helper deboner, which means customers only need to purchase the meat and segment it. Sunby deboners can quickly debone the meat and has less influence on the meat quality during the processing. Moreover, there are many models of deboners to meet your different demands.
After processing, minced poultry can be made into chicken nuggets, sausages, etc.. The remaining crushed bone can be made into pet feed because it contains a lot of protein to that makes for high quality nutritional supplements.
