振动筛分机如何保护筛网

威猛振动

[b][b]解决 振动筛筛网保护问题我们首先应该来看一下振动筛网过快破损的主要原因： 1、网的质量问题是一个引起筛网破损过快的重要因素。筛网的材质如果达不到物料的筛分要求，筛网损坏的就很快，我们在客户在选择旋振筛时注意事项中列举了筛网的分类及如何选择合适的筛网。　　2、筛网张紧力度不够，以致引起筛网颤动，通常沿筛网边缘或包边压条处断裂或损坏。　　　　3、筛网一般有上部的筛分层和下部的受力层，要求这2层之间紧密贴合，如果筛网预张紧工艺差，当筛网底部的受力层绷紧时，筛分层没有拉紧，那么做筛机工作时筛网上下颤动的距离过大，和筛框接触部分不能有效压紧，这也是引起筛网损坏过快的原因之一。　　4、物料的投料问题。因为在振动筛工作过程中不断的投料，但是如果一次投料过多，阻碍物料在筛面上正常运动，不但容易使筛网疲劳变松，而且会大大降低物料的处理量。一次性给予大量的物料，会使本身处于不平衡运转的电机负荷突然增加，不但容易损坏筛网，而且容易造成振动电机的损坏，所以在投放物料时要均匀的投料。在有强大冲击力的给料方式，必须给振动筛加装缓冲料斗，物料直接冲击筛网会消耗振动源所产生的激振力，更容易造成筛网破损及筛网疲劳。　　　　然后我们再来看一下解决方法：　（1）首先在选择振动筛时选择质量可靠的筛网；　（2）经常检查筛网的张紧度；　（3）检查筛网是否压实。　（4）如果是筛分液体，有强大冲击力时最好加装料斗或缓冲器。　（5）如果有物料堆积，尽快查找原因如调整振动电机偏心块等。

很愿意与这样讨论技术而非纯做广告的商家接触

I can go back to HBeAg (Later I learned that three months can not be good governance). Three positive and carriers can continue to work. parajumpers jakke norge When the list of published, I obviously found far from me and my good colleague, sharing a dormitory to see me will be a rush scattered. Originally, Parajumpers Jakke Salg I did not think of what to see them do this Parajumpers salg norge to jakke parajumpers me, straight up the Parajumpers barn salg pressure. The entire company Parajumpers frakker are talking about Hepatitis B is an infectious Parajumpers p? Salg disease, to the dead. That time Parajumpers Norge hepatitis B has not yet reached this knowledge, Parajumpers Jakke the 2013 parajumpers norge state in terms Parajumpers Salg of publicity and rarely. That life Parajumpers pjs jakke together is Parajumpers Jakke necessary to infection, and now think is ridiculous. Get the Parajumpers Norge complement month's salary, I set foot parajumpers pjs on the way home. Parajumpers Jakke After returning home, I did not dare to his sick told my parents that day to Parajumpers parka eat, sleep, asleep wanted, I was not soon to leave this world and the like, depressed. Days half do not go out, Parajumpers Norge I do not want to Parajumpers Salg go to therapy, because there is no money, but also Parajumpers Salg hear people say that this is a rich man's disease, cure little money I do not want Parajumpers oslo salg to add to the burden of the Parajumpers Norge family. Inside the brain think Parajumpers Jakke the more I began to feel the feeling of pain in the liver area. Day do not want to get up, do not want to eat rice. That child was none other than Parajumpers Salg the mother also! ! My mother obviously feel I was born and Parajumpers Norge serious illness,
