CYH-Large Flow Horizontal Stainless Steel Seawater Transfer Pump

Large Flow Horizontal Stainless Steel Seawater Transfer Pump

CYH pumps have the following design features:

The pump cover is fixed on the middle bracket through the stopper, and then the pump cover is clamped in the middle through the connection between the pump body and the stopper of the middle bracket. The pump body is axially inhaled, radially discharged, and foot-supported, and can be directly fixed on the base. The suspension component is fixed on the middle bracket through the stopper and supported on the base by the suspension bracket. For easy disassembly, an extended coupling is designed, and the inlet and outlet connection pipelines, pump body and motor can be maintained during maintenance. Only the middle connection of the coupling needs to be removed to withdraw the rotor component for maintenance.

Precautions for using Stainless Steel Seawater Transfer Pump：

• This type of stainless steel chemical centrifugal pump can be installed with different forms of mechanical seals according to different use conditions, such as internal single-end balanced and unbalanced types, double-end balanced and unbalanced types, external mechanical seals, etc. Depending on the selected seal type, its use method and precautions are also different.
• Since mechanical seals are generally suitable for use in clean media without suspended particles, the newly installed pipeline system and liquid storage tank should be carefully rinsed to prevent solid impurities from entering the mechanical seal end face and causing the seal to fail.
• In media that are easy to crystallize, mechanical seals should be used with care to rinse frequently. Before restarting after stopping, the crystals on the mechanical seal should be cleaned.
• The mechanical seal should be disassembled carefully, and it is not allowed to be knocked with a hammer or iron tools to avoid damaging the dynamic and static ring sealing surfaces.
• If there is dirt that cannot be removed, try to remove the dirt, rinse it clean and then disassemble it to avoid damaging the sealing components.
• Before installing the mechanical seal, all sealing components should be checked for failure or damage. If so, they should be repaired or replaced.
• The relative friction sealing surface of the dynamic ring and the static ring should be strictly checked, and no minor scratches, bumps or other defects are allowed. All other parts, including the pump body, impeller, sealing chamber, etc., should be rinsed clean before assembly, especially the end faces of the dynamic and static rings, which should be carefully wiped with a clean, soft cloth or cotton yarn, and then coated with a layer of clean grease or engine oil.
• Pay attention to eliminating deviations during assembly. When tightening the screws, tighten them evenly to avoid deflection and make the seal ineffective.
• Correctly adjust the compression of the spring. After the pump is installed, when the rotor is turned by hand, you should feel that the sealing spring has a certain amount of compression, but can rotate lightly and flexibly without a sense of biting. If it feels too tight or the disc does not move, it should be loosened appropriately.
• For mechanical seals with external flushing, the flushing wave should be turned on before starting to fill the sealing chamber with sealing liquid. When stopping, stop the pump first and then turn off the sealing flushing liquid.
