Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] see Figure 1-Figure 5 , the seismic analysis method of waste heat removal pump includes the following steps:
[0018] Step 1. Preliminary structural design. According to the relevant technical requirements of the nuclear power plant, a preliminary structural design is made for the waste heat discharge pump.
[0019] According to the functional requirements of nuclear power plants for waste heat discharge pumps, the waste heat discharge pumps for nuclear power plants are designed. At the same time, it meets the hydraulic performance requirements of the waste heat discharge pump and the requirements of high structural rigidity. flow Q d =910m 3 h -1 , head H des =77m, speed n d =1490rpm, inlet diameter D s =270mm, impeller outlet diameter D 2 =513mm, blade outlet width b 2 =49mm.
[0020] Step 2: Use 3D modeling tools to carr...
