Embodiment Construction
[0010] See figure 1 with figure 2 As shown, the special volute Francis turbine unit for cooling tower is composed of three parts: the volute Francis turbine in the middle, the fan 1 in the upper part, and the water distributor 8 in the lower part. The volute Francis turbine consists of two parts: a horizontal cavity volute 6 and a wheel fan system installed in the central cavity. Volute 6 protruding part is cavity water inlet pipe 9, and from this pipe and volute 6 tangent intersects, has horizontal water outlet narrow mouth 15 on the inner wall of ring volute 6 housings. The water inlet pipe 9 communicates with the draft pipe of the central air-conditioning circulating water system. The upper and lower end surfaces of the volute 6 are connected with a connecting disk 16 . The wheel fan system consists of a fan shaft 2, a shaft sleeve 3 that passes through it from top to bottom, upper, middle and lower flanges 4, 5, 11, a circular wheel fan blade 12 with a hole in the cent...
