Abstract
The utility model relates to a hollow output shaft of a cooling tower fan. A high-quality medium-carbon seamless steel tube is adopted, both ports of the seamless steel tube are sealed by the same material by way of welding, and after being tempered, the seamless steel tube is reprocessed, so that the hollow output shaft is produced. On the basis of the conventional solid output shaft of the fan, the structure is changed to form the newly structured output shaft of the cooling tower fan, which is characterized by material saving and energy saving and can increase the efficiency of the cooling tower fan.
Description
Technical field
The utility model belongs to the output shaft of blower fan of cooling tower technical field, particularly blower fan of cooling tower.
Background technique
No matter be industrial production or daily life, cooling tower all obtains using very widely.The used heat that produces in industrial production or the refrigeration process process generally will be led away with once-through cooling water.When not possessing the direct current cool condition, then need to cool off with cooling tower.Generally speaking, cooling tower is to pump air by the fan blade of rotation, thereby reaches the effect of cooling.
Fig. 1 is the theory structure schematic representation of existing blower fan output shaft.Existing blower fan output shaft 5 is solid output shafts.This solid output shaft is owing to the variation of carrying, and the diameter of axle also will change accordingly usually, thus the also corresponding increase of energy consumption that blower fan self produces, the also corresponding reduction of the efficient of blower fan.Yet because the extensive use of cooling tower, manufactory must improve the quality of products and reduce cost and the efficient that improves blower fan dominates the market,
At present, the output shaft of domestic blower fan of cooling tower industry blower fan product all adopts solid shaft.Because carrying is bigger, the diameter of axle is bigger usually, thus the also corresponding increase of energy consumption that blower fan self produces, the also corresponding reduction of the efficient of blower fan.Therefore must there be a kind of novel output shaft to substitute existing solid shaft.
The model utility content
In order to solve the above problems, the utility model provides a kind of novel output shaft to replace existing solid output shaft.Both satisfied and carried big requirement, solved fan efficiency again, improved the efficient of blower fan, reduced the cost of blower fan owing to the thick reduction that causes of input shaft.
The utility model changes solid output shaft into the heavy wall hollow output shaft.Select the middle carbon seamless steel pipe of high-quality for use, the mode that adopts welding with the material of identical material at the two ends of steel pipe is after heat treatment carried out processing again with closed at both ends.So just made hollow output shaft.
Adopt this hollow output shaft, reduced the weight of output shaft, the efficient of blower fan has corresponding raising, has saved steel and energy consumption, also corresponding the alleviating of the building structure of cooling tower carrying simultaneously.

Embodiment
Describe the utility model in order better to illustrate below in conjunction with accompanying drawing.
With reference to figure 2, this is the theory structure schematic representation of blower fan hollow output shaft of the present utility model.Fig. 3 is the structural representation of blower fan hollow output shaft of the present utility model.Blower fan hollow output shaft 4 comprises steel pipe 1 and is arranged on the termination 2,3 at its two ends.Steel pipe 1 is selected the middle carbon seamless steel pipe 1 of excellent performance for use, the material with the identical material of seamless steel pipe is adopted in the termination 2,3 at two ends, termination 2,3 is placed on the two-port hollow position of steel pipe 1, modes such as employing welding manner are carried out welded closure respectively with the hollow position of the two-port of termination 2,3 and seamless steel pipe 1, have so just formed the seamless steel pipe of a two-port sealing.Heat-treat again, carry out processing again.Make hollow blower fan output shaft.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present utility model.That is to say that what the utility model adopted is the blower fan hollow output shaft, hollow steel pipe 1 is fixedlyed connected with termination 2,3, and the seamless steel pipe that forms the two-port sealing gets final product.
Adopt hollow output shaft of the present utility model, reduced the weight of output shaft, the efficient of blower fan has corresponding raising, has saved steel and energy consumption, also corresponding the alleviating of the building structure of cooling tower carrying simultaneously.
Claims (2)
1. a blower fan of cooling tower hollow output shaft is characterized in that, comprises a seamless steel pipe and the termination that is arranged on its two ends, and seamless steel pipe forms a hollow shaft that seals with the termination that is separately positioned on two ends.
2. blower fan of cooling tower hollow output shaft according to claim 1 is characterized in that the termination is connected it by welding manner with seamless steel pipe.
