Axial Flow Pump for Locomotive
The axial flow pump is mainly composed of front and back shell, main body, impeller, guide vane, bearings and motor. The impeller, is installed at the end of the shaft directly, rotates to create pressure. The transformer oil is lead to main flow channel by guide vane, meanwhile, the guide vane converts kinetic energy that comes out from impeller into pressure to force oil circulation. The pump can be a part of the pipe line due to the inlet and outlet of the pump are in the same axis. Therefore, the transformer oil flows through the outer of motor directly which is able to bring the heat away immediately.
Centrifugal Pump for Locomotive
It is mainly composed of pump body, impeller, motor housing, bearing and motor. The centrifugal impeller is connected to the motor directly. The high-rotating impeller generates a centrifugal force and drives the transformer oil to flow through the volute. Then the volute converts a part of kinetic energy of transformer oil to pressure energy. So that the transformer oil flows out from the pump outlet and leads to the circulation of the transformer oil.
