通风管道风机维护和贮存!

发布时间:2020/02/12

1.使用环境应经常保持整洁,风机表面保持清洁,进、出风口不应有杂物。定期消除风机及管内的灰尘等杂物。
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.只能在风机完全政党情况下方可运转,同进要保持供电设施容量充足,电压稳定,严禁缺相运行,供电线路必须为专用线路,不应长期用临时线路供电。
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.风机在运行过程中发现风机有异常声、电机严重发热、外壳带电、开关跳闸、不能起动等现象,应立即停机检查。为了保证安全,不允许在风机运行中进行维修。检修后应进行试运转五分钟左右,确认无异常现象再开机运转。
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.根据使用环境条件不定期对轴承补充或更换润滑油脂(电机封闭轴承在使用寿命期内不必更换润滑油脂),为保证风机在运行过程中的良好的润滑,加油次数不少于1000小时/次,封闭轴承和电机轴承,加油用ZL–3锂基润滑油脂填充轴承内外圈的2/3。严禁缺油运转。
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.风机应贮存在干燥的环境中,避免电机受潮。风机在露天存放时,应有防雨措施。在贮存与搬运过程中应防止风机磕碰,以免风机受到损伤。
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.
择风机壳主要看冷镀锌板的镀层厚薄。薄的易锈,不宜选用;风机进风罩有镀锌钢板和玻璃2种材质,选用镀锌钢板为好;与之匹配的电机功率有750瓦和1100瓦2种,选择1100瓦的电机为好;风机类型较多,材质有不锈钢、镀锌钢板、铝合金、彩钢板,从性能而言,宜选用不锈钢风叶。风叶造型多种多样,性能好的造型和加工工艺均复杂;转动总成有压铸铝、铸铁2种,相比之下,压铸铝性能较好;百叶窗自动开启装置有离心锤式、重力锤式和风吹式。从经验看,离心锤式较稳定,重力锤式易受积尘影响,启闭易失灵。风吹式主要用于36寸风机。百叶窗主要看其密合性是否优良。
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.
在电力、钢铁、水泥、造纸等行业中大量使用的风机设备,因输送的气体介质中含有大量的硬质粉尘颗粒和酸性气体,这些设备的过流部件,受到强烈的冲刷腐蚀,尤其是其心脏部件叶轮,在其叶片的末端运行线速度达到160米每秒,磨损速度比其它部位更为严重。据统计,使用普通的碳钢或一般耐磨钢16Mn制造的叶轮,一般使用寿命只有半年,更短的只有几十天,虽然使用过各种表面防磨措施如堆焊,喷涂,喷焊、涂覆高分子耐磨材料等,使用寿命也难以得到显著提高。比较常用的方法中,以堆焊使用比较多,效果尚可,一般能使用一年以上而不需要大面积修理。其缺点是由于堆焊输入大量热量,如果控制不好,会导致叶轮变形,而且不能反复修理使用。热喷涂喷焊也有同样的问题,而大大限制了它们的应用。
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.
目前一种较好的方法是在叶轮活蜗壳便面粘贴或者镶嵌耐磨陶瓷,由于耐磨陶瓷有良好的耐磨性能,可以大大提高分机的耐磨性能。
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.
