As the core component of the generator sealing oil system, the maintenance and care of the HSNH-280-43NZ recirculation pump is crucial. The pump maintenance spare parts package is designed to provide a comprehensive parts replacement solution, like a miniature treasure house for equipment maintenance, which can cope with various wear and failures that may occur in the pump body.

Opening the HSNH-280-43NZ recirculation oil pump spare parts package is like entering a miniature treasure house for equipment maintenance. From precision sealing components to powerful sleeves, each spare part is carefully selected for different parts and maintenance needs of the pump, forming a master key in the hands of maintenance personnel, ready to solve any problems of the pump at any time.

Mechanical seal components – including dynamic rings, static rings, springs and auxiliary seals. These parts are in direct contact with the sealing oil and are prone to wear or corrosion after long-term operation. Regular replacement can avoid leakage. The mechanical seal component is mainly used inside the pump body to prevent the sealing oil from leaking and prevent external impurities from entering the pump cavity. When impurities are found in the sealing oil or abnormal leakage occurs in the pump body, the sealing component should be replaced immediately.

Bearing kit – Contains radial and thrust bearings that support the pump shaft and reduce friction during rotation. Worn bearings can cause increased vibration in the pump, affecting pump stability and efficiency. The bearing kit is located at both ends of the pump shaft and bears radial and axial loads. When the pump vibrates abnormally or the noise increases, it may be a sign of worn or damaged bearings, and the bearing kit needs to be replaced.

Impeller and sleeve – The impeller is responsible for pushing the fluid, while the sleeve protects the shaft from wear. These two components may need to be replaced after long-term use due to corrosion or foreign body damage. The impeller and sleeve are located in the center of the pump and are directly involved in the oil delivery process. The shape and size of the impeller have a direct impact on the performance of the pump, and any damage may lead to reduced pump efficiency, so the condition of the impeller and sleeve needs to be checked regularly.

Coupling and elastic element – The coupling connects the motor and pump, and the elastic element absorbs vibration and keeps the transmission smooth. Regular inspection and replacement can extend the life of the equipment. The coupling and elastic element ensure smooth and unimpeded power transmission between the motor and the pump. If the coupling or elastic element ages, it will not only increase energy consumption, but may also cause greater mechanical failures.

The rational use and management of the HSNH-280-43NZ pump maintenance spare parts kit is the basis for ensuring the long-term stable operation of the seal oil recirculation pump. Regular inspection and timely replacement of worn parts can not only avoid sudden failures, but also significantly improve the performance and service life of the pump. Engineers and technicians in the power industry should be familiar with the functions and applications of these spare parts so that they can take prompt action when necessary to ensure the continued safe operation of power generation facilities.
