In the production process, if the electric welding or polishing treatment of the screen frame is uneven and has burrs, the rubber sealing ring also has shock absorption and buffering effect on the upper and lower screen frames in addition to the actual effect of tightness. If the edge is uneven or the polishing treatment is incomplete during the production and processing of the screen frame, unevenness or burrs will appear, and the continuous friction of the screen frame during the operation of the machine equipment will cause the dense components to crack.

What factors will affect the storage time of rubber sealing ring.
1. Sealing ring temperature: 5°C ~ 25°C is the ideal storage temperature. Avoid contact with heat sources and sunlight. Before use, the seal removed from low-temperature storage should be placed in an environment of 20°C.
2. Humidity: The relative humidity of the warehouse should be less than 70% to avoid over-wet or over-dry, and no condensation.
3. Light: Avoid sunlight and strong artificial light sources containing ultraviolet rays. Anti-ultraviolet bags provide better protection. It is recommended that the windows of the warehouse be painted with red or orange paint or film.
4, radiation: to avoid ionizing radiation damage to the seal.
5. Oxygen and ozone: Rubber materials should be avoided from being exposed to circulating air. This can be achieved by packaging, winding, storing in a closed container or other appropriate methods.
Rubber sealing ring is not only used for sealing machinery and equipment, but also has a very important function, that is, to reduce the friction and vibration in the middle of the components, and to maintain the machinery and equipment. Silica gel, pc polycarbonate, vulcanized rubber rubber, spring, etc. can be used as hydraulic seals of vibrating screens. According to the investigation, some customers will crack the hydraulic seals when using them, in fact, the reasons for this situation are likely to have several aspects directly below.
The quality of rubber sealing rings is not up to standard. At present, a wide range of hydraulic seals are made of silicone raw materials, but the quality of hydraulic seals used by different manufacturers is also different. If the raw materials of hydraulic seals are hard or the quality of silicone keys is not good, the cracking difficulties will occur after the machinery and equipment have been running for a period of time. If such problems often occur, the cost of related spare parts will be increased.
