Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. No power distribution cabinet wind balls should be paired balls wind turbine without power distribution control box must match the corresponding fan (mean power, voltage, pneumatic control forms, etc.). Fan wiring by professional electrician wiring, the wiring must be correct and reliable, consistent with the corresponding number in particular number and fan wiring terminal at the electrical control box on the fan casing should be reliable grounding must be reliable, can not connect to ground zero instead. Must have safety devices to prevent accidents by professionals familiar with the relevant safety requirements without power installation and wiring installed typhoon. Join the fan duct with a separate import and export support, do not allow the weight of the pipe overlapping parts added to the fan; wind turbine installation should pay attention to the horizontal position of the fan, the fan and the ground connection to the combination of surface and out of the wind pipe should be adjusted, making it a natural fit, can not be forcibly join. Wind power installation without the ball, hand or lever toggle wheel, check whether there is too tight or collision phenomenon steel roof fan manufacturers, whether or interfere with the rotation of goods factory roof fan manufacturers, under no anomalies before trial the exposed part of the operation, the fan should be gearing shield (user-supplied) if the fan is not connected to the inlet pipe, also need to purchase protective nets or other mounting device (user-supplied). Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. No power ventilation Measures shall be able to use the following dressing how to perform repairs without power ventilation becomes difficult problems, ventilation is the widely used class of farmers have a fan on the ventilation in the work process, because of the speed particularly 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, an outer circumferential uneven particularly sensitive, but this is not the core part fine sense of balance request is not high. 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 welded to the roof fan manufacturers, increase the quality of it balanced, or rubbed off with angle grinder impeller focused welding marks, the same can be achieved and to achieve a balanced, so you can look good and keep trimming machine implementation of normal work. Pay attention to the natural roof fan manufacturers 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 attempts 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.
