专注通风管道加工·排烟罩

　　虽然目前风机防磨方法很多，但大多数是局部的和被动的，一种既经济又切实可行的防磨方法亟待提出。从气动设计的角度出发，通过改变粒子轨迹，从根本上降低磨损是风机防磨措施的发展方向。

　　Although the wind preventing wear many methods, but most of them are local and passive, an economical and feasible method to put forward anti abrasion. From the perspective of aerodynamic design, by changing the particle trajectory, fundamentally reduce wear is the development direction of wind abrasion - resistant measures.

　　风机长期运行造成磨损是再说难免的，那么风机都有哪些磨损形式呢，接下来就由山东通风管道加工带大家了解一下：

　　Fan running for a long time, wear and tear is inevitable, then what kind of fan wear form, we come to understand below.

　　1.磨粒磨损：离心风机凸凹不平的接触表面，因相对运动下的锉削效应或界面间分散的固体颗粒的研磨作用所导致的磨损。它对叶轮磨损的程度影响大。在风机中固体颗粒以一定的速度与零件表面作相对运动就会引起磨粒磨损。

　　1. abrasive wear: centrifugal fan uneven surface of contact, due to the relative movement of the file effect or the interface between the solid particles caused by grinding wear. It has the greatest influence on the degree of impeller wear. In the fan, solid particles with a certain speed and relative motion of the surface of the parts, will cause abrasive wear.

　　2.疲劳磨损：由于表面疲劳应力(或温度或冲击)引起表面裂纹或鳞屑脱落所致。

　　2. fatigue wear: as a result of surface fatigue stress (or temperature or impact) caused by surface cracks or scaling off.

　　1.吸附磨损：研究表明，离心风机在其它条件相同时，即使提高加工表面的加工精度等级和洁净度，使彼此贴合更好，但其磨损并不降低，反而因界面贴近，分子吸附作用显著，加重了界面的磨损，称此为吸附磨损。

　　1. adsorption wear: the results show that the centrifugal fan under the same other conditions, even improve the surface machining accuracy level and cleanliness, make each other better fit, but the wear is not reduced, but because the interface to molecular adsorption significantly, increased the wear of the interface, called for the adsorption of wear.

　　2.冲刷磨损：因固体颗粒对金属表面的冲刷而引起的表面擦伤。

　　2. erosion wear: surface erosion caused by erosion of solid particles against metal surfaces.
