擇風(fēng)機殼主要看冷鍍鋅板的鍍層厚薄。薄的易銹，不宜選用；風(fēng)機進風(fēng)罩有鍍鋅鋼板和玻璃2種材質(zhì)，選用鍍鋅鋼板為好；與之匹配的電機功率有750瓦和1100瓦2種，選擇1100瓦的電機為好；風(fēng)機類型較多，材質(zhì)有不銹鋼、鍍鋅鋼板、鋁合金、彩鋼板，從性能而言，宜選用不銹鋼風(fēng)葉。風(fēng)葉造型多種多樣，性能好的造型和加工工藝均復(fù)雜；轉(zhuǎn)動總成有壓鑄鋁、鑄鐵2種，相比之下，壓鑄鋁性能較好；百葉窗自動開啟裝置有離心錘式、重力錘式和風(fēng)吹式。從經(jīng)驗看，離心錘式較穩(wěn)定，重力錘式易受積塵影響，啟閉易失靈。風(fēng)吹式主要用于36寸風(fēng)機。百葉窗主要看其密合性是否。

The thickness of the coating on the cold galvanized plate is the main factor for selecting the fan case. Thin and easy to rust, not suitable for selection; the fan inlet hood has two materials of galvanized steel plate and glass, which is better to choose galvanized steel plate; the matching motor power has two kinds of 750 watt and 1100 Watt, which is better to choose 1100 watt motor; there are many types of fans, which are made of stainless steel, galvanized steel plate, aluminum alloy, color steel plate, and from the performance point of view, stainless steel fan blade should be selected. There are many kinds of fan blade models, and the modeling and processing technology with good performance are complex; there are two kinds of rotating assembly: Die Casting Aluminum and cast iron, in contrast, the performance of die casting aluminum is better; the automatic shutter opening device includes centrifugal hammer type, gravity hammer type and wind blowing type. From experience, the centrifugal hammer is relatively stable, the gravity hammer is easily affected by dust accumulation, and the opening and closing are easy to fail. Wind blowing type is mainly used for 36 inch fan. Shutter mainly depends on its good tightness.

在電力、鋼鐵、水泥、造紙等行業(yè)中大量使用的風(fēng)機設(shè)備，因輸送的氣體介質(zhì)中含有大量的硬質(zhì)粉塵顆粒和酸性氣體，這些設(shè)備的過流部件，受到強烈的沖刷腐蝕，尤其是其心臟部件葉輪，在其葉片的末端運行線速度達到160米每秒，磨損速度比其它部位更為嚴(yán)重。據(jù)統(tǒng)計，使用普通的碳鋼或一般耐磨鋼16Mn制造的葉輪，一般使用壽命只有半年，更短的只有幾十天，雖然使用過各種表面防磨措施如堆焊，噴涂，噴焊、涂覆高分子耐磨材料等，使用壽命也難以得到顯著提高。比較常用的方法中，以堆焊使用比較多，效果尚可，一般能使用一年以上而不需要大面積修理。其缺點是由于堆焊輸入大量熱量，如果控制不好，會導(dǎo)致葉輪變形，而且不能反復(fù)修理使用。熱噴涂噴焊也有同樣的問題，而大大限制了它們的應(yīng)用。

In the power, steel, cement, paper and other industries, a large number of fan equipment are used. Because the gas medium contains a large number of hard dust particles and acid gas, the flow passage parts of these equipment are strongly eroded and corroded, especially the heart part of the impeller, which runs at the end of the blade at a linear speed of 160 meters per second, and the wear rate is more serious than other parts. According to statistics, the impeller made of ordinary carbon steel or ordinary Wear-resistant Steel 16Mn has a general service life of only half a year, and the shortest one is only dozens of days. Although various surface anti-wear measures such as surfacing, spraying, spray welding and coating of polymer wear-resistant materials have been used, the service life is also difficult to be significantly improved. Among the commonly used methods, overlay welding is widely used, with acceptable effect. Generally, it can be used for more than one year without large area repair. The disadvantage is that a lot of heat is input into the surfacing, if the control is not good, the impeller will be deformed, and can not be repaired and used repeatedly. Thermal spray welding has the same problem, which greatly limits their application.

目前一種較好的方法是在葉輪活蝸殼便面粘貼或者鑲嵌耐磨陶瓷，由于耐磨陶瓷有良好的耐磨性能，可以大大提高分機的耐磨性能。

At present, a better method is to paste or inlay wear-resistant ceramics on the surface of the movable volute of the impeller. Because the wear-resistant ceramics have good wear-resistant performance, it can greatly improve the wear-resistant performance of the extension.
