    离心风机的几种防磨措施!
    来源:www.jntchbt.com 日期:2019-07-17 15:32:13

      离心风机在运用中叶片磨损现象经常呈现,如何才干改善离心风机这种磨损状况。下面就由经历丰厚的山东通风管道厂家为大家引见几种防磨措施:

      The blade wear phenomenon of centrifugal fan often appears in operation. How to improve the wear condition of centrifugal fan? Here are several anti-wear measures introduced by Shandong Ventilation Pipeline Manufacturers who have experienced abundant experience:

      1、对叶片外表停止处置:对叶片外表能够停止渗碳、等离子堆焊、喷涂硬质合金、粘贴陶瓷片处置。这些办法均能够在一定水平上增加叶片外表的硬度,从而进步叶片的耐磨性,不过各种处置工艺均存在一定难度,不易操作或是价钱高等要素降低了对叶片停止处置的可行性。

      1. Stop disposal of blade appearance: Carburizing, plasma surfacing, spraying cemented carbide and bonding ceramics on blade surface can be stopped. These methods can increase the hardness of the blade surface at a certain level, so as to improve the wear resistance of the blade. However, there are some difficulties in all kinds of disposal processes, and the factors of difficult operation or high price reduce the feasibility of stopping the disposal of the blade.

      2、外表喷涂耐磨涂层:这种办法是比拟倡议的,操作起来简单,本钱也不高,但涂层磨损很快,大约需求3-5个月就重新停止外表耐磨涂层的喷涂。

      2. Appearance Spraying Wear Resistant Coatings: This method is comparable to the initiative, simple to operate and low cost, but the coating wears quickly. It takes about 3-5 months to stop the spraying of wear resistant coatings.

      3、改良叶片构造:能够经过对叶片构造的改造来降低磨损,比方将叶片工作面加工成锯齿状、变中空叶片为实心叶片、叶片加焊防磨块等办法。

      3. Improving blade structure: It can reduce wear through modification of blade structure, such as processing blade working face into serrated shape, changing hollow blade into solid blade, welding blade anti-wear block and so on.

      4、前置防磨叶栅:在易磨损处装置防磨叶栅后,能够阻止粒子向后盘及叶根处活动,从而将粒子的集中磨损转化为平均磨损,进步了叶轮的耐磨性,延长风机的运用寿命。

      4. Front anti-wear cascade: After installing anti-wear cascade at the most vulnerable wear point, it can prevent particles from moving towards the rear disc and blade root, thus transforming the concentrated wear of particles into average wear, improving the wear resistance of impeller and prolonging the service life of fan.

      5、运用高效除尘安装:离心风机运转环境中的粉尘也会加剧风机磨损,倡议采用除尘安装,净化风机工作环境,以降低离心风机磨损。

      5. Effective dust removal installation: Dust in centrifugal fan operating environment will also aggravate fan wear. It is recommended to adopt dust removal installation to purify fan working environment in order to reduce centrifugal fan wear.

      山东厨房排烟采用的离心风机先的运用是从它的启动开端的。有时分会呈现启动失败或者启动时间十分长的问题,呈现这个状况的缘由有很多。假如电动机拖不动,就检查平安机构的设定值;假如电动机额定功率过低,就改换电动机;假如起动程序不正确,就调整起动设备;假如当起动时功率耗费过大,就核实当起动时气体流量控制机构能否处在关闭位置;假如转子卡住了,就用手盘动风机以检查和调查卡住缘由(摩擦、有障碍物等);假如在电动机的接线处电压过低,就检查电源线电压—如损耗过大,加大电源线。

      The centrifugal fan for smoke exhaust in Shandong kitchen was first used from its start. Sometimes the club presents the problem of starting failure or very long starting time. There are many reasons for this situation. If the motor cannot be pulled, check the setting value of the safety mechanism; if the rated power of the motor is too low, change the motor; if the starting procedure is incorrect, adjust the starting equipment; if the power consumption is too high when starting, check whether the gas flow control mechanism is in the closed position when starting; if the rotor If the voltage is too low at the connection of the motor, check the voltage of the power line - if the loss is too large, increase the power line.

      很多时分用户会发现叶轮总是在白白的耗费能量。气体经由前盖与集流器之间的泄露构成轮回活动。都要坚持一定的间隙,离心透风机的前盖与集流器之间和机壳与转轴之间。以保证风机旋转的牢靠性。这样能在很大水平上缓解这个现象。

      In many cases, users will find that the impeller is always in white energy consumption. The gas leakage between the front cover and the collector constitutes cyclic activity. Must adhere to a certain gap between the front cover of the centrifugal ventilator and the collector, and between the casing and the rotating shaft. To ensure the reliability of fan rotation. This can alleviate this phenomenon to a great extent.

      山东厨房排烟离心风机在运用常呈现的问题就是风机的振动了,想要从基本上处理这个问题也不是一个简单的事,但是假如降低风机的转速是一个十分好的方法,而这个方法的效果也为显着。不过还需求用户依据所运用风机的详细状况来判别终究运用什么办法才干愈加的合理。

      Shandong kitchen smoke exhaust centrifugal fan in the use of the most common problem is the vibration of the fan, want to basically deal with this problem is not a simple matter, but if the speed of the fan is a very good method, and the effect of this method is the most remarkable. However, users are also required to judge what method is more reasonable in the end according to the detailed conditions of the fan used.
