O-rings are prone to failure due to improper use of daily work and other factors, such as overheating of the rubber ring. The failure of the O-ring will not only delay the daily operation, but also waste manpower and material resources and cause losses. Therefore, you must be familiar with the solutions for different situations.
1. Overheating of the O-ring: If the O-ring is overheated, check the sealing chamber of the centrifugal pump and its cooling device as soon as possible. This inspection is mainly to check whether there is any blockage in the equipment. If there is a blockage, it should be cleaned up in time.
2. Improper selection of O-ring overheating specifications: Improper selection of O-ring will lead to permanent deformation, affecting use, not only causing the O-ring to lose its original performance and break, but also prevent the sliding parts from moving. So choose carefully and match.
3. O-ring extrusion: O-ring sometimes has a small space, and when the space is small, extrusion will occur. At this time, all parts of the O-ring should be adjusted immediately to improve the narrow space.
4. O-ring compression set: Another indicator for evaluating the sealing performance of O-ring is the compression set of the selected material. Under the action of pressure, the O-ring, which is an elastic element, produces elastic deformation, and as the pressure increases, permanent plastic deformation also occurs.
5. The hardness of the O-ring: The hardness of the O-ring material is the most important indicator for evaluating the sealing performance. The hardness of the O-ring determines the amount of compression of the O-ring and the maximum allowable extrusion gap of the groove.
