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...

Abstract

The invention discloses a volute mixed flow water turbine unit special for a cooling tower. The volute mixed flow water turbine unit special for the cooling tower is composed of a middle volute mixed flow water turbine, an upper fan and a lower water distributor. The volute mixed flow water turbine is composed of a horizontal cavity volute and a turbine vane system mounted inside the central hollow portion of the horizontal cavity volute; the extending portion of the volute is a cavity water inlet pipe; from the tangent intersection of the cavity water inlet pipe and the volute, a horizontal water outlet is formed around the inner wall of a volute housing, and the water inlet pipe is communicated with the draft tube of a circulating water system. The volute mixed flow water turbine unit special for the cooling tower is simple in structure, small in size, free from power consumption, noise and maintenance, low in drifting loss and very applicable to supporting low-cost operation of the cooling tower of a small building.

Description

technical field [0001] The invention relates to a volute mixed-flow water turbine unit specially used for a cooling tower, which belongs to the field of central air conditioning, and in particular to a cooling tower unit. Background technique [0002] The traditional central air-conditioning cooling tower is an electric fan type, that is, the motor installed on the top of the tower drives the fan in the tower to rotate, so as to realize the heat exchange of air and water to achieve the purpose of cooling. Its disadvantages are: high power consumption, high noise, unable to guarantee safe operation in explosion-proof and high-risk environments, and it is difficult to stabilize the gas-water ratio in the best state, which affects the cooling effect. The loss of floating water is large, and the amount of water needs to be replenished frequently, and the daily maintenance workload is heavy. The patent number is 200820228871.9, and the utility model patent named "Spiral Case Fra...
