应对离心风机叶轮磨损的问题可以使用哪些方法

2018-12-20 07:15:33 常州市星火铝艺制品有限公司 阅读

对于离心风机的使用用户来说,磨损问题无时无处不在,那么离心风机在使用过程中会出现磨损分为多种情况,主要hi指轴承之间的磨损,再就是叶轮、整机的磨损这些磨损现象严重的话会直接导致离心风机的使用效果不能发挥出来,由于磨损的方面比价多,我们在本章节主要以叶轮的磨损问题出发点,为用户寻找几个能应对叶轮磨损问题的方法和技巧,以便能更好的使用风机

For the use of centrifugal fans users, wear problems are ubiquitous, then the centrifugal fans in the use of the process of wear can be divided into a variety of situations, mainly hi refers to the wear between bearings, and then impeller, machine wear these serious wear phenomenon will directly lead to the use of centrifugal fans can not play a role In this chapter, we mainly start with the problem of impeller wear and tear, and find several methods and skills to deal with the problem of impeller wear and tear for users, so that we can better use the fan.

改进工艺路线是一个比较典型的方法,尽量将离心风机置于除尘器之后,如:风机置于增湿塔或管道增湿之后,烘干热源抽风机置于除尘器之后均大大利于防止风机的磨损,表面粘贴或焊接陶瓷,将耐磨工程陶瓷利用高强度耐高温胶粘剂或特殊焊接工艺复合在风机叶片表面上,该技术要重点解决防脱落问题。等离子堆焊,堆焊时叶片变形大,而且反复焊接会导致叶面产生裂缝,易产生事故。对叶片表面可以进行渗碳,渗碳工艺难度大,实际渗碳时,渗碳层的部位和厚度要由叶片厚度和磨损情况以及渗碳工艺决定。热喷涂,采用等离子喷涂方法或氧乙炔火焰,在叶片磨损表面喷涂陶瓷或碳化钨或者喷焊镍基+碳化钨合金。

Improving the technological route is a typical method. Putting the centrifugal fan behind the dust collector as far as possible, such as: the fan after humidifying tower or pipeline, drying heat source fan after the dust collector are greatly beneficial to prevent the fan from wearing, surface pasting or welding ceramics, wear-resistant engineering ceramics will use high strength and resistance. High temperature adhesives or special welding processes are combined on the surface of the fan blades, and the anti-shedding problem should be solved. Plasma surfacing welding, surfacing blade deformation, and repeated welding will lead to cracks on the blade surface, easy to cause accidents. It is difficult to carburize the blade surface. The position and thickness of carburizing layer are decided by the blade thickness, wear and carburizing process. Thermal spraying, using plasma spraying method or oxyacetylene flame, spraying ceramic or tungsten carbide or spraying welding nickel-based + tungsten carbide alloy on blade wear surface.

减少叶轮磨损的方法还需要用户从防腐蚀做起,很多时候风机的腐蚀会加重风机的磨损现象,因此如何在使用中减少风机的腐蚀现象,也是用户使用风机的过程中需要研究的一个课题,保障风机的顺利谁用仅仅从这些方面来入手是远远不够的,我们都知道风机能不能保持最长的使用效果,和平时对风机的保养维护程度是分不开的,一个完善的保养方案是用户必须要具备的。

The method of reducing impeller wear also needs the user to start from anticorrosion. In many cases, the corrosion of the fan will aggravate the wear phenomenon of the fan. So how to reduce the corrosion phenomenon of the fan in use is also a subject that the user needs to study in the process of using the fan. Hand is far from enough, we all know whether the fan can maintain the longest effect, and peacetime maintenance of the fan is inseparable, a perfect maintenance program is the user must have.
