Abstract
The invention discloses a novel combined type spindle seal for a hydraulic power fan of a cooling tower. The novel combined type spindle seal for the hydraulic power fan of the cooling tower consists of a rubber type flat-plate seal and a fiber woven packing seal; the problem that a spindle seal of a hydraulic power fan leaks water can be effectively solved; and the purposes of self compensation, energy conservation and zero maintenance of the seal are achieved. According to the technical scheme, a spindle is provided with two seals which are the rubber type flat-plate seal and the fiber woven packing seal, and the two seals form the combined seal. The spindle seal mainly comprises fiber woven packing, a spring, a spindle jacket, a packing gland, a sealing seat, a rubber type flat-plate seal, a sealing pressure plate, a connecting piece and the like. The sealing seat is fastened to a top cover; the spindle jacket is hung on the spindle and is in contact with the fiber woven packing in the sealing seat so that water is sealed; and the rubber flat-plate seal is arranged on a lower flange of the spindle jacket and is tightly pressed through the sealing pressure plate. During working, the rubber flat-plate seal is in contact with the sealing seat due to inner water pressure, so that the water is sealed. The novel combined type spindle seal for the hydraulic power fan of the cooling tower is simple and novel in structure, convenient to mount and use, high in work efficiency and free of maintenance, and is energy-saving, environment-friendly and safe; running cost is saved; the novel combined type spindle seal is a great innovation for the field of spindle seals for the hydraulic power fan of the cooling tower; and the economy is high.

Root.Seal receptacle puts together on top cover, and main shaft sheath is suspended on main shaft and contacts water shutoff with the fibrage packing in seal receptacle；
On the other hand rubber type plate seal is disposed with main shaft sheath lower flange and is compressed by sealing clamp.Rubber flat plate seals
Because internal water pressure contacts water shutoff with seal receptacle during work.
The present invention based on the operative practice of existing cooling tower hydraulic power blower fan, by carrying out to the structure of existing main shaft seal
Analyze and optimize and be verified in real machine test, a kind of cooling tower hydraulic power blower fan combined main that final optimization pass is designed
Sealing it is characterised in that：The combination sealing forming with fibrage packing_seal for rubber type plate seal, that is, on main shaft
Setting two seals, realize double sealing effect.
According to cooling tower hydraulic power blower fan of the present invention with combined main sealing it is characterised in that fibrage packing
Realize the self compensation regulatory function after abrasion by spring and packing gland.
According to a kind of cooling tower hydraulic power blower fan of the present invention with combined main sealing it is characterised in that：Combination type
It is sealed in while realize double sealing effect, self-compensating function can be realized under the pretightning force of spring and internal water pressure, reliable
Property high, safe, non-maintaining, save operating cost.
The present invention is advantageous in that：The present invention passes through to improve and optimizate, and here provides a kind of cooling tower hydraulic power blower fan group
Box-like main shaft seal, this combined sealing structure overcomes the inefficiency that most of existing hydraulic power blower fan main shaft seals exist
Under, run that water leakage is big, the problem of poor reliability, have the characteristics that high working efficiency, water leakage be few, high reliability, non-maintaining.
Brief description
Fig. 1 invention combination spindle sealed structural representation
Wherein：Main shaft sheath 1, spring 2, packing gland 3, seal receptacle 4, sealing clamp 5, rubber type plate seal 6, fiber
Braiding packing 7, main shaft 8.
Specific embodiment
Below in conjunction with accompanying drawing 1, the present invention is described in detail, and the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.
Based on the embodiment in the present invention, it is all that those of ordinary skill in the art are obtained under the premise of not making creative work
Other embodiment, broadly falls into the scope of protection of the invention.
It is an object of the invention to overcoming work efficiency present on existing cooling tower hydraulic power blower fan main shaft seal technology
Lowly, run that water leakage is serious, the problem of poor reliability, a kind of Novel cooling tower hydraulic power blower fan combined main sealing be provided,
Have the characteristics that high working efficiency, water leakage be few, high reliability, non-maintaining, be finally reached that hydraulic power blower fan is energy-efficient, safety is steady
The fixed use requirement run.
As shown in Figure 1：A kind of cooling tower hydraulic power blower fan combined main sealing of the present invention, it is improved by：Main
