Basic Structure: The fundamental construction of the centrifugal pump consists of six main components: impeller, pump housing, shaft, bearings, seal ring, and packing gland. Impeller The impeller is a critical component of the centrifugal pump, featuring high speed and powerful force. The blades on the impeller play a major role. The impeller must undergo a static balance test before assembly. The inner and outer surfaces of the impeller must be smooth to minimize frictional losses in water flow. Pump shaft The shaft of the pump serves to connect the motor via a coupling, transferring the motor's torque to the impeller, thus it is the main component for transmitting mechanical energy. Pipe centrifugal pump bearing This is a component that fits over the pump shaft to support it, available in two types: rolling bearings and sliding bearings. Rolling bearings use cow oil as a lubricant; it should be applied appropriately, generally 2/3 to 3/4 of the volume: too much can cause overheating, while too little will result in noise and overheating! Sliding bearings use transparent oil as the lubricant, and should be filled to the oil level line. Too much oil will leak along the pump shaft and become wasteful, while too little can cause the bearing to overheat, burn, and lead to accidents! During the operation of the water pump, the bearing temperature usually runs around 60 degrees, with an average of 85 degrees. If it's higher, investigate the cause (such as impurities, whether the oil has turned black, or if water has entered) and handle it promptly! Sealing Ring Also known as a leakage reducer. An excessive gap between the impeller inlet and the pump casing can cause water in the high-pressure area of the pump to flow through this gap to the low-pressure area, affecting the pump's flow rate and efficiency! A too small gap can cause friction and wear between the impeller and the pump casing. To increase backflow resistance, reduce internal leakage, and extend the service life of the impeller and pump casing, a sealing ring is installed at the junction of the pump casing inner edge and the impeller outer edge, with the sealed gap maintained between 0.25 to 1.10 mm. Filling Case Primarily composed of packing, water seal rings, packing sleeve, packing cover, and water seal pipes. The function of the packing chamber is mainly to seal the gap between the pump housing and the pump shaft, preventing water inside the pump from leaking out and external air from entering the pump. Always maintain a vacuum inside the water pump! When friction between the pump shaft and packing generates heat, the water seal pipe channels water into the water seal ring to cool the packing! Ensuring the normal operation of the water pump. Therefore, during the routine inspection of the pump, special attention should be paid to the packing chamber. It is recommended to replace the packing after approximately 600 hours of operation. Application Vertical hot water pumps are suitable for metallurgy, chemical industry, textile, wood processing, papermaking, as well as for increasing pressure and circulating water supply in boilers for restaurants, bathrooms, hotels, etc. They are used for urban housing heating circulation and operate at temperatures below 120℃. 2. Vertical high-temperature centrifugal pumps are used for: energy, metallurgy, chemical industry, textile, papermaking, and boiler high-temperature hot water pressure boosting circulation in restaurants, bathrooms, hotels, etc. Suitable for city housing heating circulation, with operating temperature below 240℃. 3. Vertical PipelineChemical PumpIdeal for conveying liquids that are free of solid particles, corrosive, and have a viscosity similar to water, suitable for industries such as petroleum, chemicals, metallurgy, electricity, papermaking, food, and synthetic fibers. Operating temperature range: -20℃ to 120℃. Installation Notes (1) The base surface of the installation must be flat, clean, and capable of withstanding the corresponding load; (2) Anchor bolts should be used where fixation is required. (3) For vertically mounted pumps, the anchor bolts must be sufficiently strong. (4) If vertically mounted, the motor must be above the pump. (5) When installing on the wall, ensure proper alignment and centering. Product Features 1. Hydraulic Model: Performance. 2. Easy Installation and Maintenance: Pipe-style installation allows for the installation of inlets and outlets like valves at any position and direction along the pipeline, making installation and maintenance extremely convenient. 3. Aesthetically pleasing: Features a stainless steel exterior for a sleek and attractive appearance. 4. Lower operating and maintenance costs: Utilizing mechanical seals, leak-free with long service life, low failure rate, resulting in reduced operating and maintenance expenses. 5. Noise Reduction: Hydraulics component design with excellent flow performance, significantly reducing flow noise. 6. Vertical structure, with minimal land area.
