32、010 - 6 - 1 Scope This Technical Specification covers requirements for electric pumps which generate the circulation of insulation liquid in traction transformers and reactors of rail vehicles and their associated cooling system. The pumps covered by this Technical Specification are rotodynamic pump
33、s driven by a squirrel cage induction motor which is immersed in the insulating liquid. CLC/TS 50537-2 gives consideration to both technical and normative requirements of the railway environment and restricts the variety provided by industry-wide standards for pumps (for example EN 50216-7 and EN IS
34、O 9906). It determines requirements and tests enabling the interchangeability especially regarding electrical, mechanical and hydraulic interfaces. Furthermore, service conditions are described. 2 Normative references The following referenced documents are indispensable for the application of this d

44、ocument, the following terms and definitions apply. 3.1 rotodynamic pump pumps based on bladed impellors which rotate within the fluid to impart a tangential acceleration to the fluid and a consequent increase in the energy of the fluid. The purpose of the pump is to convert this energy into pressur
45、e energy of the fluid to be used in the associated piping system. In-line pumps and radial pumps are rotodynamic pumps 3.2 in-line pump (axial flow pump) pump with the suction and delivery flow being on the same axis. In the case of transformer pumps, the axis of the flanges is usually the same as t
46、he axis of rotation of the pump rotor 3.3 radial flow pump pump with the suction and delivery flow pointing in perpendicular direction. For transformer pumps the axis of the delivery flange is usually perpendicular to the rotation of the motor 5)Superseded by EN 60085:2008. DD CLC/TS 50537-2:2010CLC
