Overheating of O ring manufactures
is usually caused by the unfavorable conditions of excessive heat generation of the sealing surfaces of centrifugal pumps. Teflon O-rings turn blue or black, O-rings harden and crack. The condition is always worst near the sealing surface. 1. Overheating of the O-ring Overheating of the O-ring is usually caused by the unfavorable conditions of excessive heat generated by the sealing surface of the centrifugal pump. Teflon O-rings turn blue or black, O-rings harden and crack. The condition is always worst near the sealing surface. Relevant corrective measures: Check the circulation of the sealing chamber of the centrifugal pump (if a cooler is installed, it should also be checked at the same time) to see if there is any blockage, etc. Check the pump for failures such as reduced suction capacity, dry running, slag formation, etc. Check the condition of the product according to the original regulations. 2. O-ring extrusion When a part of the O-ring is forced through a small gap, extrusion will occur. This extrusion can occur when seals are assembled or assembled with excessive force, or when operating pressures and temperatures are too high. O-ring extrusion can also occur when the shaft seal elements are adjusted in situ, if the dimensions are out of limit, resulting in a large gap between the elements. PTFE O-rings are curled, and rubber seals
O-rings are peeled or torn. Relevant corrective measures: Check the assembly method and operating conditions to ensure that all parts of the seal are adjusted to the original design requirements or readjusted by the manufacturer. 3. Unqualified O-rings When the O ring manufactures are not properly selected, permanent deformation such as swelling and undercut will occur, and the consequences will not only cause the O ring manufactures themselves to lose their original performance and break, but also prevent the sliding parts from moving. . Relevant corrective measures: Check the original product working conditions of the shaft seal to see if the material is suitable. If it is not suitable, the material and size of the O-ring should be re-selected. Company website: https://www.orksealing.com/
Most people who see a in operation for the first time are amazed at how well the custom rubber seals is managed.
Ruichen Sealing Co., Ltd. is committed to supplying the consumer and our customers with the finest, high-quality products and to leading the industry in rubber seals custom rubber seals.
There are many advantages associated with .
Ruichen Sealing Co., Ltd.’s model also predicts (i) a positive effect of management on firm performance; (ii) a positive relationship between product market competition and average management quality (part of which stems from the larger covariance between management with firm size as competition strengthens); and (iii) a rise (fall) in the level (dispersion) of management with firm age.
