Canned pump is a non-sealing pump, and the pump and the driving motor are sealed in one in a pressure vessel filled with pumping medium, the pressure vessel is only statically sealed and is provided by a set of wires to provide a rotating magnetic field and drive the rotor. The driving of the ordinary centrifugal pump is to connect the impeller shaft of the pump with the electric shaft through the coupling, so that the impeller rotates together with the electric motor. This structure eliminates the rotary shaft seal of the conventional centrifugal pump, so that it can be completely leak-free.
Structure type
1. The integrated structure of the motor and the water pump, the water pump and the motor are coaxially connected.
2. There is a shielding sleeve on the inner side of the stator and the outer side of the rotor, and the inner side of the shielding sleeve is connected with the inside of the pump.
3, the installation method is divided into horizontal and vertical.
4. The motor cancels the cooling fan, and the motor is cooled by the circulating medium between the stator and the rotor, and the surface of the motor base is cooled.
Features
1. The integrated structure of the motor and the pump is all statically sealed, so that the electric pump is completely leak-free.
2. Fully enclosed, leak-free structure can transport toxic and harmful liquid substances.
3. The use of shielded water-cooled motor and the elimination of the cooling fan to make the pump quiet and quiet operation, suitable for occasions with high requirements on environmental noise.
4. The graphite sliding bearing lubricated by the conveying medium makes the running noise lower and does not require manual refueling, which reduces the maintenance cost. In recent years, the bearing material has increased silicon carbide SIC, super hard, etc., and the service life is better than graphite bearing.
5. The vertical structure can be installed on the pipeline like a valve, the installation is convenient and fast, and the motor and the impeller can be extracted only during maintenance, without removing the pipeline.
6. It can be installed and operated with shock absorber or cushion to make the electric pump have lower noise during operation.
