The engraving machine users all feel the same. The engraving machine will generate heat after a long time of use. At this time, if the motor is too hot, it will cause some negative effects. We should consider how to dissipate heat. When the motor temperature of the stone engraving machine is too high, you can choose to stop the machine to rest for a period of time and continue to work. You can also add heat radiation in the motor to ensure that the heat is dissipated in time.
Here are some tips on heat dissipation: The temperature range of electric heating depends on the insulation of the engraving machine motor. Generally, the internal insulation will be destroyed at high temperature (130 degrees). As long as it does not exceed 130 degrees, the motor will not be damaged, but at this time, the surface temperature is below 90 degrees. Therefore, the surface temperature of the motor is normal at 70-80 degrees. A simple temperature measurement point thermometer is useful, and you can also roughly determine: 1-2 seconds to touch, no more than 60 degrees, only hand touch, about 70, 80 degrees; a few drops of water quickly vaporize, then 90 degrees .
The heat dissipation of the engraving machine is also very important, and passive heat dissipation and air cooling are commonly used. For low-power machines, passive cooling can be used to solve it. Using the temperature difference between the ambient temperature and the equipment, and natural cooling, it is relatively simple and low cost. It is suitable for heat dissipation of low-power, short-time working equipment.
Air-cooled heat dissipation is more extensive, and most of them also use this method to dissipate heat. Air-cooled heat dissipation uses a fan to blow heat away, thereby quickly dissipating heat. But air cooling also has many disadvantages. For example, when working for a long time, the noise is indeed very loud. And it is easy to accumulate dust, resulting in poor heat dissipation.
Water-cooled heat dissipation is to add a heat-absorbing cold head on the surface of the heating core, which can flow through the water, thereby transporting heat to achieve the effect of cooling. Or there is a water cooling device on the outside, which works the same as the previous one. The disadvantage of water cooling is the high cost. The advantage is that its heat dissipation effect is quite good, and it will not be disturbed by dust.
With the increase of high-power engraving machines, the problem of heat dissipation has become increasingly serious. As a new trend in the field of heat dissipation, water cooling will definitely play an increasingly important role.
