1. The use environment should always be kept clean, the fan surface should be kept clean, and the air inlet and outlet should be free of sundries. Remove dust and other sundries in the fan and pipe regularly.

2.只能在風機完全政黨情況下方可運轉，同進要保持供電設施容量充足，電壓穩定，嚴禁缺相運行，供電線路必須為專用線路，不應長期用臨時線路供電。

2. The fan can only be operated under the condition of complete party. The capacity of power supply facilities shall be sufficient and the voltage shall be stable. It is strictly prohibited to operate without phase. The power supply line must be a special line and shall not be powered by temporary lines for a long time.

3.風機在運行過程中發現風機有異常聲、電機嚴重發熱、外殼帶電、開關跳閘、不能起動等現象，應立即停機檢查。為了保證，不允許在風機運行中進行維修。檢修后應進行試運轉五分鐘左右，確認無異常現象再開機運轉。

3. If the fan is found to have abnormal sound, the motor is seriously heated, the shell is electrified, the switch trips and cannot be started during the operation of the fan, it shall be stopped immediately for inspection. In order to ensure safety, it is not allowed to carry out maintenance during fan operation. After maintenance, the test run shall be carried out for about five minutes, and the machine shall be started again after confirming that there is no abnormal phenomenon.

4.根據使用環境條件不定期對軸承補充或更換潤滑油脂（電機封閉軸承在使用壽命期內不必更換潤滑油脂），為保證風機在運行過程中的良好的潤滑，加油次數不少于1000小時/次，封閉軸承和電機軸承，加油用ZL–3鋰基潤滑油脂填充軸承內外圈的2/3。嚴禁缺油運轉。

4. Supplement or replace the lubricating grease for the bearing irregularly according to the use environment conditions (it is not necessary to replace the lubricating grease for the closed bearing of the motor in the service life). In order to ensure the good lubrication of the fan in the operation process, the oil filling times shall not be less than 1000 hours / time. The closed bearing and the electric bearing shall be filled with zl-3 lithium base lubricating grease to fill 2 / 3 of the inner and outer rings of the bearing. It is strictly forbidden to operate without oil.

5.風機應貯存在干燥的環境中，避免電機受潮。風機在露天存放時，應有防雨措施。在貯存與搬運過程中應防止風機磕碰，以免風機受到損傷。

5. The fan shall be stored in a dry environment to avoid motor damp. When the fan is stored in the open air, rainproof measures shall be taken. In the process of storage and handling, the fan shall be prevented from bumping, so as to avoid damage to the fan.

擇風機殼主要看冷鍍鋅板的鍍層厚薄。薄的易銹，不宜選用；風機進風罩有鍍鋅鋼板和玻璃2種材質，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；風機類型較多，材質有不銹鋼、鍍鋅鋼板、鋁合金、彩鋼板，從性能而言，宜選用不銹鋼風葉。風葉造型多種多樣，性能好的造型和加工工藝均復雜；轉動總成有壓鑄鋁、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、重力錘式和風吹式。從經驗看，離心錘式較穩定，重力錘式易受積塵影響，啟閉易失靈。風吹式主要用于36寸風機。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、造紙等行業中大量使用的風機設備，因輸送的氣體介質中含有大量的硬質粉塵顆粒和酸性氣體，這些設備的過流部件，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重。據統計，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，會導致葉輪變形，而且不能反復修理使用。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.
