The UD-1,6 wind turbine is high-speed. Due to the high speed of rotation in the wing, large forces arise. Therefore, if the wing breaks and flies away, then it can cause an accident. In addition, by rotating rapidly, the wings can touch and injure anyone who climbs onto the site and inadvertently approaches the wind turbine. To avoid accidents and ensure reliable operation of the installation, the safety and technical operation of the wind turbine should be strictly followed, which are discussed in more detail below. When caring for the UD-1,6 wind turbine, the electrical part requires the most attention. When looking for the causes of a malfunction, it is useful to have a portable electric lamp with a long cord. It is convenient to check faults in all electrical circuits with such a lamp. So, by connecting it to the wires of the generator (with the batteries disconnected), it is easy to check whether the generator is giving current. If you turn off the generator and connect a lamp to the same wires, then by pressing the armature of the relay and thereby supplying current from the battery, you can check the rest of the electrical circuit. In relatively light winds, the engine sometimes cannot move. In order to start it from the ground, it is necessary to supply current to the generator from the batteries by pressing the relay contact with your hand or by pressing an additional button made especially for such a start. The main conditions for the normal care of the wind turbine while observing the most important safety rules are the following: 1. Climbing to the platform of the working bridge under the head of the wind turbine is possible only when the wind is not strong and only when the wind turbine is stopped. 2. Being at the top of the bridge, it is necessary to be tied to the support post with a fire belt or a rope tested for five times the weight of a person. 3. Every week in the first month of operation and then monthly, it is necessary to check the fastening of all bolts, in particular the bolts that fasten the wings to the hub and to the generator shaft. The rope tied to the tail at the first launch must be untied when it is no longer necessary, but while it is tied, care must be taken that it does not fall into the rotating wings. 5. At least 2 times a year, you need to wash the engine ball bearings with gasoline and lubricate them with oil. 6. Once every 15-20 days it is necessary to lubricate the friction bearing in the generator, cables and roller axles. 7. In ice, ice should be cleared from engine parts or sprinkled with table salt on the wings. 8. If the wings are out of balance, stop the engine immediately, find out and eliminate the cause. 9. It is necessary to ensure that the distance from each wing to the pole at any position of the wing and change in wind direction is not less than 50 mm, considering that the wing bends during operation and turns of the engine, and therefore can touch the pole and collapse. 10. Pantograph rings should be cleaned every 1-2 months. If there is no pantograph, then more than 5 turns of cable and wires around the pole should not be allowed to form. If the turns are formed, then you need to rotate the engine around the pole so as to completely unwind the cable and wire. 11. All engine parts must be painted before installation and repainted every 3 years. Wooden wings, tail and shovel should be replaced every 3 years. Author: Perli S.B.
