雖然目前風機防磨方法很多，但大多數(shù)是局部的和被動的，一種既經(jīng)濟又切實可行的防磨方法亟待提出。從氣動設(shè)計的角度出發(fā)，通過改變粒子軌跡，從根本上降低磨損是風機防磨措施的發(fā)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.

　　風機長期運行造成磨損是再說難免的，那么風機都有哪些磨損形式呢，接下來就由山東通風管道加工帶大家了解一下：

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

　　1.磨粒磨損：離心風機凸凹不平的接觸表面，因相對運動下的銼削效應(yīng)或界面間分散的固體顆粒的研磨作用所導致的磨損。它對葉輪磨損的程度影響大。在風機中固體顆粒以一定的速度與零件表面作相對運動就會引起磨粒磨損。

　　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.疲勞磨損：由于表面疲勞應(yīng)力(或溫度或沖擊)引起表面裂紋或鱗屑脫落所致。

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

　　1.吸附磨損：研究表明，離心風機在其它條件相同時，即使提高加工表面的加工精度等級和潔凈度，使彼此貼合更好，但其磨損并不降低，反而因界面貼近，分子吸附作用顯著，加重了界面的磨損，稱此為吸附磨損。

　　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.沖刷磨損：因固體顆粒對金屬表面的沖刷而引起的表面擦傷。

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