Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. Currently in the industrial large-scale plant in common natural ventilation has streamlined roof natural ventilation, cyclone-type roof natural ventilation and a variety of roof exhaust hood and the like. Standards were prepared where the 1990s had 96K105-1 ~ 3 "tubular hood and Accessories", "circle umbrella hood" and "conical hood." Many domestic production of all types of ventilators, the material according to the requirements of different points of stainless steel, plain carbon steel and mineral glass and steel. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. No power ventilation can use the following approach to the implementation of how to repair no power ventilation purposes of repair becomes difficult problems, ventilation is the widely used a class of farmers having ventilation fan on the roof ventilation in the course of work, Because speed is particularly high, and the working surroundings ferocious, closed lax, sand with opportunities for wind caused severe wear. This article reveals a kind of simple and practical way to repair. Ventilation by moving all balanced experiments, because of its high speed, therefore, it is also very high balancing requests skylight roof ventilation, especially fan impeller, an outer circumferential imbalance particularly sensitive, but in this tiny central portion of It does not request a higher sense of balance. According to this feature, the impeller prone to problems, and no power ventilators can use the following approach to the implementation of dressing: 1. For the purposes of a simple dynamic balanced impellers experiment approach is also very simple. The impeller support the use of hand struck after the date it Manman rotation, reach a balanced place to the lowest point will stop and teeter. If there is emphasis on the over the impeller can be spot-welded to the increase in quality it balanced, or rubbed off with a grinder impeller focus welding marks, the same can be achieved and to achieve a balanced, so it is possible to see defensive unit trimmed the purposes of normal operation a. Pay attention, not with welding Xpress spot welding, welding marks will be left to the impeller, lest affect balanced rectangular skylight ventilation fan impeller, attempt to reach the finishing, causing a greater loss in the fan's repair history. 2. Should the rivet head is worn impeller can be pressed through the impeller hub body and welded wire welding plant ventilation skylights, so wear rivet head is returned to its original posture. 3. easy to type into the rivet hole of fatigue cracks in the situation, can the entire root, or who do not speak the absence of new welding 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 rivet holes corresponding to said cracks after welding when the rest of the match rivet welding and welding trap remaining the same length, no power ventilation to ensure the quality of welding up the same. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. How then should debug an axial fan, axial fan in the proper installation, the first part of the function of each commission, see if you can work properly. 2, first check the fan when turning is smooth, you can try to see if there is jammed blade struck or without rotation. 3. Internal check whether the fan was not removed debris and keep it clean inside and clean with a rag to clean up. 4, the operator after checking the pipe throttle state, away from the fan. 5, after the fan starts, it continues to rotate after half an hour, stop working, check all parts for loose phenomenon. These are described in the fan commissioning after installation, the desire to help you.
