Description
Technical field
The utility model relates to a kind of water wheel fan, particularly relates to a kind of upside-down mixed flow water wheel fan being applicable to devaporizer and small-sized cooling tower.
Background technique
Mixed-flow wheel blower fan is widely used in the cooling tower with backwater potential energy because noise is low, efficiency is high, for substituting original motor and speed reducer, reaches energy-saving and cost-reducing object.Current substantial amounts by the cooling unit of motor direct-drive, such as devaporizer and small-sized cooling tower, its inner space is all narrower and small.Existing mixed-flow wheel blower fan, adopt water wheel arrangement under, fan is at upper mounting type (see accompanying drawing 4), and the mixed-flow wheel blower fan of this kind of structure is not suitable for using on the narrow and small cooling unit in above inner space.
Summary of the invention
The purpose of this utility model is the upside-down mixed flow water wheel fan providing a kind of and existing mixed-flow wheel assembling mode contrary, to overcome the above-mentioned deficiency existing for prior art.
For solving above technical problem, the technological scheme that the utility model is taked is: a kind of mixed flow water wheel fan of upside-down, comprise water wheel arrangement and fan blade, described water wheel arrangement comprises intake pipe, outlet pipe, mixed flow runner, described intake pipe is positioned at outlet pipe top, described mixed flow runner is arranged in intake pipe, the transmission shaft upper end of mixed flow runner is driven to be connected with the bearing unit A on water wheel arrangement shell, described fan blade is arranged on the bottom of water wheel arrangement, and is connected with the transmission shaft passing outlet pipe bottom.
Its further technological scheme is: the junction of described transmission shaft and outlet pipe bottom is provided with bearing unit B, comprises Sealing, bearing and gland, and described fan blade is connected to successively through the transmission the tip of the axis of Sealing, bearing and gland.
Its further technological scheme be: the diameter that described transmission shaft stretches out the position of below gland is less than the diameter at the position of more than gland.
Owing to taking above technological scheme, the mixed flow water wheel fan of the upside-down of the utility model has following beneficial effect:
Although devaporizer and small-sized cooling tower driving power little, be generally 7.5-30 kilowatt, but substantial amounts, number of applications is the decades of times of large and medium-sized cooling tower, the utility model solves existing mixed flow fan can not be applied to the devaporizer of narrow space and the problem of small-sized cooling tower, can be widely used in that there is the devaporizer of backwater potential energy and small-sized cooling tower, substitute drive motor, reach energy-saving and cost-reducing object;
2. the upside-down mixed flow water wheel fan of the utility model, its transmission shaft diameter stretching out below gland are less than the diameter of more than gland, convenient maintenance and change bearing unit;
3. the upside-down mixed flow water wheel fan structure of the utility model is simple, easy for installation, can make full use of original mounting bracket and install, and substitutes original motor.
Be further described below in conjunction with the technical characteristics of drawings and Examples to a kind of upside-down mixed flow water wheel fan of the utility model.

Embodiment
As depicted in figs. 1 and 2, a kind of mixed flow water wheel fan of upside-down, comprise water wheel arrangement and fan blade 5, described water wheel arrangement comprises intake pipe 1, outlet pipe 2, mixed flow runner 3, described intake pipe is positioned at outlet pipe top, described mixed flow runner 3 is arranged in intake pipe, can install the stator 8 for guiding current in intake pipe; Drive transmission shaft 4 upper end of mixed flow runner 3 to be connected with the bearing unit A6 on water wheel arrangement shell, described fan blade 5 is arranged on the bottom of water wheel arrangement, and is connected with the transmission shaft 4 passing outlet pipe 2 bottom.
Described transmission shaft 4 is provided with bearing unit B7 with the junction of outlet pipe bottom, comprises Sealing 71, bearing 72 and gland 73, and described fan blade 5 is connected to successively through the end of the transmission shaft 4 of Sealing 71, bearing 72 and gland 73.
The diameter that described transmission shaft 4 stretches out the position 42 of gland less than 73 is less than the diameter at the position 41 of gland more than 73.
During installation, body 11 is arranged on the top of the mounting bracket 10 of small-sized cooling tower or devaporizer 9, replaces original fan drive motor, and fan blade 5 is arranged on the below (as shown in Figure 3) of mounting bracket 10.
Working principle: current are entered by intake pipe 1, presses after several angle water conservancy diversion through stator 8, and enter promotion mixed flow runner 3 in body and rotate, thus drive transmission shaft 4 to rotate, current are flowed out by outlet pipe 2 after completing acting by mixed flow runner 3; Transmission shaft 4 and then the fan blade 5 under driving outlet pipe 2 are rotated, and carry out radiating and cooling to the circulating water in devaporizer or cooling tower 9.
