Solenoid valve is an automatic basic element used to control the direction of fluid, which belongs to the actuator; it is usually used in mechanical control and industrial valves to control the direction of the medium, so as to achieve the control of the valve switch.
Predictive maintenance helps schedule replacement of equipment parts before errors occur, and can reasonably schedule replacement times, such as during idle periods of the machine, without taking up production time. This not only ensures the efficiency of the production line, but also improves the overall agility of the plant.
Fully automatic high-speed N95 mask production line, including automatic raw material delivery, automatic transportation, cutting nose bridge strips, welding forming, nose bridge filling, ear strap welding, folding, cutting and recycling, and other complete process automation to complete the entire production process from coil raw materials to mask finished products .
As for the development of the industry, the gap with foreign countries, and the problems existing in the industry, we have not paid much attention to it. And it is precisely these problems that are affecting the development direction of this industry.
As the saying goes, there is still a high mountain, so many senior designers will feel that they are just a person who can skillfully operate CAD, not enough to become a master in the eyes of others.
There are two major factors to consider in the law of fluid flow: flow rate and flow rate . Let’s look at each separately.
Several common unfolding formulas for sheet metal.
The so-called chamfer of the bearing, that is, the intersection of the horizontal and vertical surfaces. Due to the production technology limitations, counterfeit bearing products are not handled satisfactorily at these corners. We can easily Identify.
Why can’t the aircraft be welded? Decades of doubt finally understood!
When the bolt is broken, the easiest conclusion that people can draw is that the strength is not enough, so most of them adopt the method of increasing the strength level of the bolt diameter. This method can increase the pre-tightening force of the bolts, and the frictional force has also been increased. Of course, the anti-loosening effect can also be improved, but this method is actually a non-professional method, its investment is too large, and the benefits are too small.
Flange bolt pre-tightening force is the pre-tightening force in the direction of the axis of the bolt generated between the bolt and the connected part under the tightening torque during the bolt tightening process.
Bearing heat treatment is directly related to the subsequent processing quality, which ultimately affects the performance and life of the parts.
When the motor is running under load, the total internal loss is converted into heat energy to increase the temperature of the motor. The poor heat resistance in the motor is the insulating material. If the load of the motor is too large and the loss is too large to make the temperature exceed the allowable limit of the insulating material, the life of the insulating material will be shortened sharply.
In the forging production, according to the law of constant volume, it is possible to carry out technological calculations such as the size of the forging, the size of the process parts and the size of the mold.
Mechanical seals have become one of the most common forms of sealing in motorized equipment in oil refining and chemical installations. Moreover, with the continuous improvement of their design and manufacturing level and the continuous development of new materials, their application scope will be further expanded.
