How to fix the semicircle of the leaf inside the three-dimensional fan?

1. Replace the fan blades. If the fan blades are badly damaged beyond repair, the best way is to replace them. You can purchase new fan blades and replace them according to the fan manual or online tutorials.

2. Glue the leaves. If only a small part of the fan blade is broken, you may consider using glue to stick the sheet. However, before gluing, you must ensure that the broken part of the sheet has been cleaned and free of dust or other debris. In addition, when using glue, you must choose a glue that can bond plastic materials, and before waiting for the glue to dry, you must maintain the shape of the sheets to avoid deformation.

Why do hair dryer blades break?

20 years.

The wind turbine blade is a thin shell structure madeof composite materials. The structure is divided into three parts: root, shell and keel. There are many types, including pointed head, flat head, hook head, pointed head with flaps, etc. The manufacturing process mainly includes male mold, female mold turning, rolling, heating and curing, demolding, surface grinding, spray painting, etc. Design challenges include aerodynamic design of blade shape, strength, fatigue, noise design, and composite material layup design. The technical difficulties mainly include mold positive processing, mold recasting and resin system selection. The blade is a large composite material structure, and more than 90% of its weight is composed of composite materials. Each generator typically has three blades, and each generator requires up to qFour tons of composite materials.

Blade maintenance. Cracks on the blade surface will generally appear after 2-3 years of wind turbine operation. Cracks are caused by low temperatures and natural vibrations of the unit. If the crack appears 8-15 meters from the root of the blade, the crack will deepen and lengthen each time the wind turbine vibrates or stops. As the cracks widen, dirt, wind and sand from the air penetrate, causing the cracks to deepen and widen. Cracks seriously threaten the safety of the blades and can cause cracking, while transverse cracks can cause the blades to break. In case of transverse cracks, reinforcement and restoration of the zipper should be used. Reinforcing and restoring the zipper requires the use of special tie bars to bond et repair the blade to its original plane.

Notes on daily use:

Is the input power charged? Turn on the power first, then turn on the switch to avoid the impact of excessive voltage and radiation on the life of the motor. If half used, the switch should be turned off. If it is stopped for a short time, it can remain on, but the air inlet must remain unobstructed and the air outlet must be kept away from objects to avoid burns. When using it, handle it with care, do not swing it too much or change gears frequently to avoid loose parts, keep the input voltage relatively stable, and prolong the life of the switch and the engine. During use, if there are abnormal phenomena such as excessive temperature, noise, sudden speed decrease, motor failure, fan blades falling, odorburnt material, foreign objects coming out of the air outlet, smoke coming from the power cord, etc. ., the power must be turned off immediately. Wait until you know the cause and resolve the problem before using it again. Don't use it for too long at a time. Intermittent use may also extend lifespan. After use, wipe the outer shell with a clean cloth and store it in a dry place away from moisture. liveIf it has been left for too long, when reused, it should be lit for two or three minutes and the moisture should be removed before use. Hair dryers should not be used in bathrooms or places with high humidity to avoid the risk of electric shock. Induction fans need to add oil to the bearings regularly. Stock fans should not add oil if it is too dry, no more than half a tastete should not be added to avoid burning the rotor or stator coil. Keep the power cord well insulated, connecting screws firm and regular maintenance to achieve safe, durable and comfortable use.
