Embodiment 1
[0067] A low-lift pumping station adopts an oblique pump device, the pumps are arranged obliquely, the inclination angle of the pump shaft is 20°, and the design flow rate of a single pump is 50m 3 / s, select the TJ04-ZL-20 water pump model tested on the same platform as the South-to-North Water Diversion pump model, and determine the pump impeller diameter D 0 It is 3.65m, the speed of the water pump is 107r / min, the water inlet channel is an inclined water inlet channel, and the water outlet channel is an inclined water outlet channel. The elevation view of the inclined pump device is as follows figure 1 As shown, from the inlet to the outlet of the pump device, there are inclined water inlet flow channel 1, water pump impeller 2, guide vane body 3 and inclined water outlet flow channel 4. The inclined water outlet channel 4 is divided into an inlet curved section 4a, a middle diffuser section 4b, and an outlet straight section 4c along the water flow direction, and a septu...
Embodiment 2
[0090] A large-scale low-lift pump station adopts a vertical pump device, and the design flow rate of a single pump is 33.5m 3 / s, select the TJ04-ZL-06 water pump model tested on the same platform as the water pump model of the South-to-North Water Diversion Project, the diameter of the pump impeller is D 0 The length is 3.15m, the speed of the water pump is 125r / min, the water inlet channel is an elbow-shaped water inlet channel, and the water outlet channel is a low hump-shaped outlet channel. like Figure 10 As shown, the vertical pump device includes an elbow-shaped water inlet channel 11 , a water pump impeller 12 , guide vanes 13 and a low-humped water outlet channel 14 from the inlet to the outlet. The low hump type outlet flow channel 14 is sequentially composed of an inlet curved section 14a, a middle diffuser section 14b, and an outlet straight section 14c from the inlet to the outlet, and an intermediate pier 17 is arranged in the middle of the outlet straight sec...
