The basic structure of a vertical pipeline chemical pump consists of six parts: impeller, pump body, pump shaft, bearings, sealing ring, and packing box.
1. The impeller is the core part of a chemical pump, with high speed and high output. The blades on the impeller play a major role, and the impeller needs to undergo static balance tests before assembly. The inner and outer surfaces of the impeller are required to be smooth to reduce frictional losses caused by water flow.
2. The pump body, also known as the pump casing, is the main body of the water pump. Plays a supporting and fixing role, and is connected to the bracket for installing bearings.

3. The function of the pump shaft is to connect with the motor through a coupling, transmitting the torque of the motor to the impeller, so it is the main component for transmitting mechanical energy.
4. Bearings are components that are fitted onto the pump shaft to support it. There are two types of bearings: rolling bearings and sliding bearings. When using butter as a lubricant for rolling bearings, it is recommended to add oil at a volume of 2/3 to 3/4. If the volume is too large, it will generate heat, while if it is too small, it will produce noise and heat up! Sliding bearings use transparent oil as a lubricant, add oil up to the oil level line. Too much oil will seep out along the pump shaft and float, and too little bearing will overheat and burn out, causing accidents! During the operation of the water pump, the temperature of the bearings can reach up to 85 degrees Celsius, usually around 60 degrees Celsius. If it is too high, it is necessary to investigate the cause (whether there are impurities, whether the oil quality is black, whether water has entered) and deal with it in a timely manner!
