Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Traditional axial fan wheel spinning reel on the relatively backward axial fan wheel plant processes are generally carried out using three roll rolling and welding rough shape without power hood, then finishing machinery, due to this backward process leading to the hub of dimensional tolerances and geometric tolerances can not be effectively guaranteed, and because of the stress and deformation of welding, but also lead to reduced accuracy of the fan, the fan affects the efficiency of China's Zhejiang mold drawing using some Blower manufacturing hub, but only a very few product model, because a larger die size wheels, costly, and the need for supporting the thousands of tonnage pressure machine in order to be implemented, and the manufacturing cost of spinning tires with only one drawing die / 20 or so, or even less, and the spinning tire tool machining cycle even shorter than the drawing die, and for the fans varieties, small quantities of product features is extremely appropriate. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. No power ventilation can use the following approach to the implementation of how dressing without power ventilation purposes becomes difficult to repair the problem, ventilation is the widely used class implements a hood or without power prices, ventilation fan on the job course, because the speed is extremely high, and work surroundings ferocious closed lax sand with opportunities for wind caused severe wear. This article revealed a class of simple and practical way to repair. Ventilators are all balanced by moving the experiment, due to its high speed, therefore, it is also very high balance requests, especially fan impeller without power hood specifications, the outer circumferential uneven particularly sensitive, but this core part of fine does not request a higher sense of balance. This is a feature based on the impeller prone to problems, and no power ventilation Measures shall be able to use the following dressing: 1. For the purposes of simplicity impeller dynamic balancing test, is also very simple way. The impeller support from the use of hand after it struck Manman rotation, reach a balanced place will stop to the bottom point and up and down. If you have to focus on the over the impeller can be spot-on, it increases the quality of balance, or rubbed with a focus on the impeller angle grinder welding marks, the same can be achieved and to achieve a balanced, so you can look good and keep trimming machine working properly implemented a. Note that in the course of the fan repair welding unavailable Xpress spot welding, the welding marks left on the wheel, so the impact of the fan impeller balancing roof without power hood wholesale attempt to reach the finishing, causing even greater losses. 2. Should the rivet head was worn impeller, the impeller can be pressed through the hub body with welded surfacing, so wear normal rivet head back to the original situation. 3. rivet hole fatigue cracks easy to type into the situation, can not have the whole root to speak about non-existent or new welding electrodes used to repair cracks in the implementation of stitching, but leaves the car to use as the center axis, proportionate implementation, the welding cracks at the rest of the welding remain on the premises, and then use a new welding trap corresponding rivet holes known cracks after welding welding remaining commensurate with the rest of the welding trap rivets same length, no power ventilation to ensure the quality of welding up the same.
