Trouble-free pumps are a major goal for all pump operators, and achieving this goal is not an easy task. Botou Haina Pump Co., LTD. Key components of the pump - mechanical seal, impeller, coupling, roller bearings and housing are worn. Maintaining a pump in good working condition is essential for equipment and systems to be cost-effective and reliable to operate. Unplanned downtime can negatively impact production schedules and the facility's bottom line.
"Any system can function only as the life of the weakest component" - this statement applies to many types of products - but especially mechanical seals. Although mechanically sealed pumps are one of the key components, they also have one of the shortest average life of service. Mechanical seals are recognized as the most responsible for pump failures and therefore represent the highest pump maintenance costs. Thus, reducing MTBF (mean time between failures) or MTBR (mean time to repair) can significantly improve pump operations and save money.
When working normally, mechanical seals are generally safe and reliable to operate with almost no wear on components. The problem occurs when the sliding surface of the mechanical seal is not adequately lubricated under dry operating conditions, eventually leading to the destruction and collapse of the seal. Industry surveys show that dry operation or insufficient lubrication is responsible for more than 50% of all mechanical seal damage, therefore, it is safe to say that about 20% of all pump failures are due to poor lubrication or dry mechanical seal operating state face.
Analysis of the service life of pump components, it was found that only 1.2 years of average service life, mechanical seals, pump components in the weakest link, the future of the weakest components, bearings, on average, three years of service life. In order to reduce pump maintenance and downtime, this will benefit the average service life of the pump's mechanical seals by increasing the service life of the bearings to match the operator.
By using mechanical seals with DiamondFaces coating, the average service life of mechanical seals is greatly increased. This allows mechanical seal pump operators to plan preventive inspections, eliminating or reducing the cost of unplanned process disruptions. By improving the mechanical seal, approximately every second of pump repair, as well as the associated downtime and production disruption of the service life, can be avoided.
These diamond crystals grow together to form a closed layer. The separation process is stimulated with the tungsten wire stretched horizontally or vertically throughout the reactor and heated to about 2,000 C. This arrangement of tungsten wire is one of the key factors to ensure that the sealing surface of the coating is completely flat and evenly coated. DiamondFaces guarantees sealing surface uniformity, which is necessary for functional reliability of mechanical seals.
DiamondFaces coated mechanical seals such as the user provide many advantages:
· Hardly worn diamond coating
· Reduce friction sliding surfaces
· Extend MTBF and MTBR values
· Greatly save energy
· Increased application range
· Shorten ROI (return on investment
These advantages can make pump life long, and can be people for a long time.
