Development of the Cooling Circulation Device for Surface Water
摘要
Abstract
The cooling circulation device for surface water is developed according to the technical specification for the cooling circulation system of the traction converter of CRH3 high speed EMU. It mainly consists of the plate heat exchanger, the inner circulation system, the outer circulation system and the electrical control cabinet. Through calculation and selection, Thermowave TL90 KCCL plate heat exchanger from Germany is adopted, which consists of 17 pieces stainless steel plates. The total area of the plates is 4.1 m2 and the thermal power of 209. 9 kW can be conducted by it. Grundfos TP50-190/2 pump and the Kaiquan KQL65/11O-2. 2-2 pump are adopted respectively as the inner circulating pump and the outer circulating pump. GBNL-3/20T cooling tower is adopted as the cooling tower. The flow regulator of the cooling fluid is composed of Siemens SKB62 electro-hydraulic valve actuator and Siemens WF45. 50 control valve. Siemens ACX32 programmable controller is adopted. The remote monitoring and control system is established. This device has been used for the routine test and the type test for the traction converter unit of CRH3 and CRH350 EMU.关键词
