Stress analysis of electric push rod
Under normal circumstances, the electric push rod is subjected to a certain mutual force on the concave and convex surfaces, and the direction of this force is the same as that of fitness exercise on the swing rod. The direction of the force points is the same. From a basic theoretical analysis, the perspective is relatively large between 370 degrees and 370 degrees. It is not difficult to see that the larger the viewing angle, the greater its bearing capacity. Therefore, when designing a floor plan, the viewing angle should be minimized as much as possible.
For electric push rods, in order to better ensure their normal operation, it is usually stipulated that the viewing angle should be controlled within 40 degrees. This not only improves work efficiency, but also reduces friction and wear. In addition, everyone must also develop an effective design plan for the support frame of the swing rod and analyze the state of cross section interaction forces.
Therefore, after fully considering the hazards of the surface of the electric push rod bearing, everyone usually divides the electric push rod into swing rods of different lengths and specifications. And changing the cylinder diameter also varies. In other words, not only must the length be controlled, but the viewing angle must also be controlled as much as possible to ensure that the pressure on the cross-section is within an acceptable range.
Then, when designing electric push rod products, everyone must consider this: the supporting frame structure can not only withstand a large amount of mutual force, but also can be completed through fitness exercises. In addition, according to different workplaces, everyone must also choose consistent raw materials. For example, aluminum alloy profiles have strong ductility, making them suitable for areas with frequent real-time fitness exercises.

Range hood push rod motor malfunction
The power line of the range hood push rod motor is in open circuit or the joint is detached. Carefully identify the open circuit or detachment point and re weld it firmly; If the on-off switch has an open circuit or poor contact, check if the circuit breaker is soldered properly. If the contact is poor, replace it with a new one;
