Mechanical Seal Complications And Repair

Many industries that use mixers or blenders have switched to mechanical seals to help mix their product. A mechanical seal is a product that connects two systems or objects together to keep the equipment running smoothly. A fitted mechanical seal should not make a high-pitched sound during use, and properly functioning mechanical seals prevent leakage and contamination by containing liquid pressure. A malfunctioning mechanical seal can be dangerous for companies mixing substances such as petrol, bio-fuel, and even some paint solutions. Occasionally, mechanical seals require repair or a second fitting to continue functioning adequately.

Repairing a mechanical seal rather than replacing one can help companies reduce costs. Two of the most important factors when it comes to repair is time-efficiency and quality. While mechanical seals may look like a simple object, they are actually made up of several parts; outer/inner gland, sleeve, collar, rings, diffusers, and others, any of which may require polish, repair, or ultimately replacement. When running mixers or agitators at high speeds, parts can occasionally become worn or dislodged, resulting in malfunction. One of the more common problems is related to chemical corrosion. Repair technicians note that the most common problems with a mechanical seal includes cracks, broken or missing parts, irregular wear, grooved surface, discoloration, or heat-related damage.

Mechanical seal failure is most likely the result of installation, pump, or application issues. Other damages are typically incurred through chemical attack, vibration, axial and radial run-out, barrier fluid, high pressure or temperature levels, or product erosion. Some mechanical seals have a max seal life. During this stage, the mechanical seal should continue to run at a stable rate, but after the lifespan has ended, some seals become worn or damaged, causing vibrations or cracks, which leads to repair or replacement. Improper selection and maintenance are the most considered factors when a seal breaks.

The high-pitched sounds caused by mechanical seals can also be remedied with the right parts provider. Silent mechanical seals can be purchased in single and dual designs to make the workplace less noisy. Upgrading to a silent mechanical seal can make the workplace a more composed and safer environment. Employees who once struggled to hear each other over the squealing sounds of mechanical seals running at high RPM levels no longer have to shout or struggle after an upgrade.
