What failures are prone to use O-rings?

O-rings are prone to failure due to improper use in daily work and other factors, such as overheating of the rubber ring. Failure of the O-ring will not only delay the daily work operation, but also waste manpower and material resources and cause losses. Therefore, you must be familiar with the solutions for different situations.

1. O-ring is overheated: If the O-ring is overheated, check the sealing cavity 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 blockage occurs, it should be cleaned up in time.

2. Improper selection of O-ring overheating specifications: Improper selection of O-ring will cause permanent deformation and affect use. Not only will the O-ring lose its original performance and break, it will also prevent the sliding parts from moving. Therefore, the choice must be carefully and matched.

3. O-ring extrusion: O-ring sometimes has a narrow space, and extrusion will occur when the space is small. At this time, all parts of the O-ring should be adjusted immediately to improve the narrow space.

4. O-ring compression set: Another index for evaluating the sealing performance of O-rings is the compression set of the selected material. Under pressure, the O-ring, which is an elastic element, produces elastic deformation, and as the pressure increases, permanent plastic deformation will also occur.

5. O-ring hardness: O-ring material hardness is the most important index for evaluating sealing performance. The hardness of the O-ring determines the compression of the O-ring and the maximum allowable extrusion gap of the groove.
