The manufacturer said that axis flow is a very energy -consuming mechanical equipment.If you use it for a long time, it will consume a lot of electricity.Through the following operations, a lot of electricity bills can be saved.Manufacturers can help energy conservation according to the following methods.1. minimize the resistance of the pipe network, reasonably select the pipeline size and installation location, and install the imported set.2. Control the radial gap between the top and the top of the shovel.3. Reasonable selection models to avoid running in inefficient areas.4. If the fan images are used alone, equipped with a suitable motor
The fan manufacturer said that the noise generated by the axis flowers has the following reasons!In fact, any fan will make more or less noise during use!The noise of the axis fans must be fully observed, the source of noise, and then targeted!The common method of reducing the noise of the axial fans is to install a blocking muffler at the inlet and export of the bearing fans.For occasions with higher noise reduction requirements, you can use it.The sound insulation box and the shock absorber should be placed between the device and the foundation.Generally speaking, the above method can be used to obtain a significant noise reduction effect.Fan manufacturers say several causes of noise 1. Fan discrete noise (rotation noise): related to the rotation of the leaf.Especially in the case of low load, this noise is more obvious.Generally speaking, there are three noise generated by the asymmetric structure around the blade and the turning of the blade opening design test rotation.(1) Inlet interference noise caused by air -conducting or metal mesh before the air inlet.(2) The rotation frequency noise generated by the leaves in the non -smooth or asymmetric shell.(3) Export interference noise caused by the existence of the guidelines behind the axis fans. Discrete noise has discrete spectrum characteristics. The noise of the radical frequency (the corresponding frequency) at the base frequency (i = 1).2. Fan: The vortex noise is caused by various separation of vortex when the air flows.There are generally four reasons.(1) When the air flow with a certain turbulence flow to the blades, the turbulent flow noise generated.(2) When the air flows across the surface of the blades, the turbulent boundary layer of the turbulent boundary layer is noise.(3) Separation vortex noise caused by the turbulent boundary layer of the blade surface at the back edge of the leaves.(4) The secondary flow noise of the top flow from the concave surface to the convex surface is taken from the concave surface to the convex surface.
The above is the energy -saving method and several causes of the noise of the axial flow fan.
