Structure principle: dlr vertical multistage centrifugal pump consists of motor and pump two parts, the motor is Y-phase three-phase asynchronous motor, the pump and the motor are connected by a coupling, the overall rigid connection, no need to use calibration. The pump consists of a stator part and a rotor part. Part of the pump stator from the water section, the middle section, different leaves, the water section, stuffing boxes and other parts. In order to prevent the stator from wearing, the stator is equipped with a seal ring, a balance sleeve and the like, and the worn parts can be replaced with spare parts. Rotor part of the shaft, the wheel, flat drums and other components. The lower end of the rotor is a water-lubricated bearing. The upper part is an angular contact ball bearing. Most of the axial direction of the pump is borne by the balance drum. The rest of the remaining axial force contacts the ball bearings to withstand the axial load. Sewage pumps, vertical sewage pumps, chemical pumps, chemical centrifugal pumps, single-stage centrifugal pumps, centrifugal pumps, corrosion-resistant centrifugal pump inlet and outlet of the junction with the paper pad by tightening to achieve tight. Seal with packing or mechanical seal, the user can choose according to need. Pump rotation direction from the drive side down to look counterclockwise rotation.
