Rubber sealing ring is not only used to seal mechanical equipment, it also has a very important role, is to reduce the friction and vibration between the parts, with protective effect on mechanical equipment. Silicone, polyurethane material, vulcanized rubber, spring, etc., can be used as the sealing parts of the vibrating screen. According to the investigation of some users in the application of the seal will break the specific situation analysis, in fact, the reason for this phenomenon is very likely to have the following aspects.

  First of all, the quality of the rubber sealing ring is not qualified. At present, the widely used sealing parts are silicone products, but the quality of the sealing parts used by different manufacturers is not the same. Such as: the sealing material is hard or the quality of silicone material is not good, it will be difficult to crack after the mechanical equipment runs for a period of time. Problems like that often raise the cost of related parts.

  Secondly, in the process of processing, such as: screen frame welding or polishing treatment uneven burr. Rubber sealing ring in addition to the actual effect of sealing, but also on the upper and lower screen frame shock absorption and buffering, such as: in the production and processing of screen frame, the edge is not smooth or polishing treatment is not complete, will occur uneven or rough edge, so that mechanical equipment operation, screen frame constant friction will make the close component crack. If this kind of situation should be found in the use of the screen frame and other places to correct the rough edge, to prevent the same problem in the future.
