Basic Structure: The fundamental construction of a centrifugal pump consists of six main parts: impeller, pump housing, shaft, bearings, seal ring, and stuffing box.
Blade Wheel
The impeller is a critical component of the centrifugal pump, featuring high speed and strong power. The blades on the impeller play a major role. The impeller must undergo a static balancing 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 coupling and the motor, transferring the motor's torque to the impeller, making it the main component for transmitting mechanical energy.
Pipe centrifugal pump bearing
This is a component that fits over the pump shaft and supports it, available in two types: rolling and sliding bearings. Rolling bearings use cow oil as a lubricant; the oil should be added appropriately, usually 2/3 to 3/4 of the volume: too much will cause heat, and too little will produce noise and heat! Sliding bearings use transparent oil as the lubricant; add oil to the oil level line. Too much oil will seep along the pump shaft and float away, while too little oil will overheat the bearing, potentially causing damage and accidents! During the operation of the water pump, the bearing temperature typically runs around 60 degrees Celsius, with an upper limit of 85 degrees. If it exceeds this, investigate the cause (such as impurities, oil discoloration, or water intrusion) and address it promptly!
Sealing Ring
Also known as a leakage ring. 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 into the low-pressure area, affecting the pump's output 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 inner edge of the pump casing and the outer edge of the impeller, with the sealed gap maintained between 0.25 to 1.10 mm.
Filling bush
Primarily composed of packing, water seal rings, packing筒, packing cover, and water seal pipes. The function of the packing chamber is mainly to seal the gap between the pump housing and the shaft, preventing water inside the pump from escaping and external air from entering the pump. Always maintain a vacuum inside the water pump! When heat is generated due to friction between the pump shaft and the packing, the water seal pipe channels water to the water seal ring to cool the packing! To ensure the normal operation of the water pump. Therefore, during the routine maintenance inspections of the pump, special attention should be given to checking the packing chamber. It is recommended to replace the packing after approximately 600 hours of operation.
