Quickly understand the structure of centrifugal pump
Time: 2024-05-29 Source: Solids Control Equipment Author: Mrek
Centrifugal pump are vane pumps that rely on high-speed rotating impellers to subject liquids to centrifugal force to achieve the purpose of transporting media. Centrifugal pumps usually consist of six parts, namely impeller, pump body, pump shaft, bearings, sealing ring, and stuffing box.
1. The impeller is the core part of the centrifugal pump. It rotates at a high speed, and the blades on the impeller play a major role. The impeller must pass a static balance test before assembly. The inner and outer surfaces of the impeller must be smooth to reduce friction losses in the water flow.
According to its mechanical structure, it can be divided into three types: closed type, semi-closed type and open type. Closed impellers are suitable for conveying clean liquids; semi-closed and open impellers are suitable for conveying suspensions containing solid particles. The efficiency of these pumps is low.
2. The pump body is also called the pump casing, which is the main body of the water pump. It plays a supporting and fixing role and is connected to the bracket where the bearing is installed.
3. The function of the pump shaft is to connect the motor with the coupling and transmit the torque of the motor to the impeller, so it is the main component for transmitting mechanical energy.
4. The sliding bearing uses transparent oil as lubricant, add oil to the oil level line. Too much oil will seep out along the pump shaft, and too little bearings will overheat and burn out, causing accidents! During the operation of the water pump, the temperature of the bearings reaches a maximum of 85 degrees, and generally operates around 60 degrees.
5. The sealing ring is also called the leakage reducing ring.
6. The stuffing box is mainly composed of stuffing, water seal ring, stuffing barrel, stuffing gland and water seal tube. The main function of the stuffing box is to close the gap between the pump casing and the pump shaft, prevent the water in the pump from flowing to the outside, and prevent outside air from entering the pump, and always maintain a vacuum in the pump!
When the friction between the pump shaft and the packing generates heat, the water seal tube must be used to trap the water into the water seal ring to cool the packing! Keep the water pump running properly. Therefore, special attention should be paid to the inspection of the stuffing box during the inspection of the water pump operation! The packing must be replaced after about 600 hours of operation.
