The impeller must pass a static balance experiment before assembly. The sealing ring is also called the leakage reducing ring. The stuffing box is mainly composed of packing, water seal ring, packing tube, packing gland and water China Submersible Drainage Pumps Factory seal pipe. The sliding bearing uses transparent oil as lubricant, and fill it to the oil level line. Always maintain the vacuum in the pump! When the pump shaft and the packing friction generate heat, the water seal pipes the water into the water seal ring to cool the packing! Maintain the normal operation of the pump. 2, the pump body is also called the pump housing, which is the main body of the water pump. The impeller is the core part of the centrifugal pump. The basic structure of a centrifugal pump is composed of six parts: impeller, pump body, pump shaft, bearing, sealing ring, and stuffing box. The blades on the impeller play a major role. The function of the stuffing box is mainly to close the gap between the pump casing and the pump shaft, and prevent the water flow in the pump from flowing outside and the outside air from entering the pump. 5.. 6. 1. Play a supporting and fixing role, and connect with the bracket for mounting the bearing. It has a high speed and high output. The role of the pump shaft is to connect with the motor by means of a coupling, and transmit the torque of the motor to the impeller, so it is the main component that transmits mechanical energy. Therefore, special attention should be paid to the inspection of the stuffing box during the itinerant inspection of the pump operation! The packing should be replaced after 600 hours of operation. 3. The inner and outer surfaces of the impeller are required to be smooth to reduce the friction loss of the water flow. Too much oil will seep along the pump shaft, and too little bearing will overheat and burn out causing accidents! During the operation of the water pump, the temperature of the bearing is as high as 85 degrees, and it generally runs around 60 degrees
