Description
Technical field
The special-purpose spiral case mixed-flow wheel of cooling tower of the present utility model unit belongs to the central air-conditioner field, relates in particular to a kind of cooling tower unit.
Background technique
Traditional air-condition cooling tower is the electric fan type, and promptly the motor drives tower internal fan by the cat head installing rotates, and realizes that the air water heat exchange reaches cooling purpose.Its shortcoming is: power consumption height, noise be big, can't guarantee safe operation under explosion-proof, high-risk environment, and gas-water ratio is difficult to be stabilized in the optimum state, influences cold effect.The water loss that wafts is big, needs frequent amount of makeup water, and the maintenance work amount is big.The patent No. is 200820228871.9, and denomination of invention preferably resolve above-mentioned defective, but it is at building for the utility model patent of " exempting from electric energy cooling tower spiral case Francis turbine ".
Summary of the invention
The purpose of this utility model is to propose a kind of no power consumption, abates the noise, reduces the drift ice loss, and is simple in structure, the reliable special-purpose spiral case mixed-flow wheel of small-sized cooling tower unit.
The purpose of this utility model is achieved in that the special-purpose spiral case mixed-flow wheel of cooling tower unit is made up of the spiral case Francis turbine at middle part, the fan on top, water-dispensing device three parts of bottom.The spiral case Francis turbine is made up of horizontal cavity spiral case and the empty in the central wheel fan system two-part located of installing.The spiral case extension is the cavity intake pipe, should begin with spiral case tangent line intersection by pipe certainly, has horizontal water outlet narrow orifice on the ring volute body madial wall.Intake pipe is communicated with the draft tube of circulation.The upper and lower end face of spiral case all is connected with interface disc.Wheel fan system is by fan shaft, wear its outer axle sleeve from top to bottom, the upper, middle and lower flange plate, and the circular wheel flabellum of center drilling, spring, nut is formed.Be equiped with bearing and water seal on the fan shaft of corresponding position, axle sleeve lower end.Axle sleeve links to each other in turn with the interface disc of upper, middle and lower flange plate, spiral case upper-end surface.All have keyway in fan shaft bottom and wheel flabellum center bore inner wall, the wheel flabellum is connected with fan shaft by key, and the horizontal water outlet narrow orifice on wheel flabellum and the volute body madial wall is in same horizontal position.The interface disc of spiral case lower end surface connects the flange plate that is equipped with three the flange plate position symmetries in spiral case top in turn, and the flange plate of below is communicated with in turn with outlet pipe, water-dispensing device.
Because carry out technique scheme, but just implementation structure is simple for this unit, volume is small and exquisite, zero power consumption, noise free, freedom from repairs, the water loss that wafts is minimum, is very suitable for supporting aedicula cooling tower low cost movement.
Description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is the special-purpose spiral case mixed-flow wheel of a cooling tower unit structural representation;
Fig. 2 is a spiral case Francis turbine decomposition texture schematic representation.
